How I went from toggling a single GPIO pin to deploying intelligent, low-power firmware on the edge — and the lessons that shaped me along the way. The first program I ever ran on a microcontroller did exactly one thing: it blinked an LED. No operating system. No framework. No safety net. Just my code, a register, and a clock ticking a few million times a second. When that LED finally blinked at the rate I intended — not too fast, not stuck on — I felt something I hadn't felt writing software before. On a bare-metal system, nothing happens unless you make it happen. There's no runtime quietly cleaning up after you. That mix of total control and total responsibility is what pulled me into embedded systems, and it's the same thread that eventually led me to running machine learning models on the edge. This is the story of that journey — from a single blinking pin to intelligent devices that sense, decide, and act on their own. The Bare-Metal Beginning Bare-metal firmware is where you learn what a computer actually is. When you write to a memory-mapped register to toggle a GPIO, or configure a UART peripheral one bit at a time, there's no abstraction hiding the hardware from you. You read the datasheet. You read the reference manual. You get the clock configuration wrong, and nothing works — no error message, just silence. Then you fix it, and suddenly bytes are streaming out of a pin at exactly the baud rate you configured. Most of my early growth happened writing low-level peripheral drivers — UART, SPI, I2C, GPIO, ADC — on ARM Cortex-M platforms. These are the unglamorous building blocks, but they teach you the discipline embedded work demands: Every byte and every milliwatt matters. On a resource-constrained MCU, you don't get to be careless with memory or power. Timing is a first-class citizen. An interrupt that fires 50 microseconds late can break the whole system. The hardware is always right. If your code and the oscilloscope disagree, the oscilloscope wins. Th

Originally published on tamiz.pro . Introduction Over-the-air (OTA) updates are a critical component of modern software ecosystems, yet they introduce complexity through network instability, device fragmentation, and rollback challenges. Meanwhile, AI agents are emerging as powerful tools for autonomous workflow orchestration. This article explores how to architect resilient developer workflows by integrating AI-driven decision-making with OTA update management systems. The Chaos of OTA Updates OTA updates face three primary challenges: Unreliable Network Context : Mobile devices frequently lose connectivity during updates Device State Fragmentation : Managing compatibility across 1000+ device configurations Rollback Complexity : Traditional systems lack real-time failure detection Traditional solutions rely on retries and checksum validation, but these fail to address root causes like partial updates on low-memory devices or race conditions during state transitions.

From data preparation and tokenizer selection to pretraining, LoRA, RLHF, evaluation, and production monitoring, this guide covers the major stages involved in training an AI model. Training an artificial intelligence model is not simply a matter of loading a dataset onto a GPU and running a few commands. A successful model requires a measurable objective, legally usable and carefully cleaned data, an architecture suited to the problem, controlled optimization, independent evaluation, and continuous monitoring after deployment. In large language model development, a mistake in any one of these stages can waste millions of training examples and a significant amount of compute. This guide explains the model development process primarily through the training of large language models. However, fundamental concepts such as dataset splitting, loss functions, overfitting, and evaluation also apply to computer vision, speech, and predictive models. The goal is not to provide a single fixed recipe. Instead, it is to explain which training approach is appropriate for which problem and to clarify the cost difference between training a model from scratch and adapting an existing model. In Brief: How Is an AI Model Trained? First, the target task and success criteria are defined. Data is collected, reviewed for licensing and privacy, cleaned, and divided into training, validation, and test sets. The model generates predictions from the input data. The difference between the prediction and the correct target is measured using a loss function. Backpropagation calculates how each parameter contributed to the error, and an optimization algorithm updates the parameters. This process is repeated under controlled conditions until the model achieves acceptable results in independent tests and safety evaluations. What Does Training a Model Actually Mean? A neural network initially contains a large number of numerical parameters. During training, the model generates a prediction for a giv

Arc 11 covered Days 71–77 of Epoch 3, and it was all about Cross-Program Invocations. In Arc 9, we wrote our first Solana program. In Arc 10, we gave that program a more useful state model with Program Derived Addresses. But our programs were still mostly working alone. They could read and update their own accounts, enforce their own constraints, and respond to instructions sent by a client. They could not directly change state owned by another program or bypass the rules that program enforced. That is an important part of Solana’s security model. The System Program owns the rules for creating accounts and transferring lamports. Token-2022 owns the rules for mints, token accounts, supply, and mint authorities. If our program needs one of those capabilities, it calls the program that owns the operation. That call is a Cross-Program Invocation, or CPI. The Web2 comparison is a service-to-service API call. One service sends a request through another service’s public interface, and the receiving service applies its own rules. A CPI works in a similar way, with one important difference: the outer and inner instructions execute as part of the same Solana transaction. If the inner call fails, the state changes made by the outer instruction are rolled back too. That combination of clear program boundaries and atomic execution is what makes Solana programs composable. Our first CPI called the System Program The arc began with the smallest useful CPI we could build. Our Anchor program accepted a sender, a recipient, and an amount of SOL to transfer. But the program did not edit the sender’s balance directly. Instead, it called the System Program’s transfer instruction. That distinction matters. Accounts on Solana are owned by programs, and the owner program controls how their data may be changed. Our program could not simply reproduce the effect of a System Program transfer by adjusting balances itself. It had to ask the System Program to perform the operation. Every CPI need

What I learned at Zone01 Kisumu's IP training Introduction Yesterday, I attended an Intellectual Property training at Zone01 Kisumu, and it fundamentally changed how I think about the code I write. As developers, we spend countless hours building software, but how many of us truly understand the value of what we create,and how to protect it? In Kenya's rapidly growing tech ecosystem, understanding IP isn't just a legal nicety, it's a competitive advantage. Whether you're building an app, contributing to open source, or launching a startup, knowing your rights can mean the difference between owning your work and losing it. This article breaks down the essential IP frameworks every software developer should know. What is Intellectual Property in Software? Intellectual Property (IP) in software encompasses legal protections designed to safeguard the rights of creators and developers. The four primary types of IP protection relevant to software are: patents, copyrights, trademarks, and trade secrets . Copyright: Protecting Your Code Copyright is the most immediate form of protection for software developers. In Kenya, copyright protection arises automatically at the moment of creation,registration is not mandatory . This means that when you write code, you automatically own the copyright to that expression, provided the work is fixed in a tangible medium . However, a crucial distinction exists: copyright protects the expression of ideas, not the ideas themselves . This principle was reinforced in the Kenyan case of Solut Technology Limited v Safaricom Limited, where the court confirmed that without access to source code, it's difficult to prove infringement because the "expression" (the code itself) wasn't shared . Key Insight: Registering your copyright with KECOBO in Kenya provides prima facie evidence of ownership and can make enforcement faster if someone copies your work . Patents: Protecting Functionality While copyright protects the expression of code, patents pro

The Idea: Hidden Instructions Inside Trusted Content Prompt injection is an attack where malicious instructions are embedded inside content that an AI is asked to process - a document, a webpage, an email, a customer support ticket. The model can't always distinguish between "data I'm reading" and "commands I should follow," so it follows the embedded instruction as if a legitimate user sent it. This gets sharper when AI agents (autonomous systems that browse the web, read files, and take actions on your behalf) are involved. A summarizer that reads a webpage might encounter hidden text instructing it to forward your conversation history somewhere, or change the tone of its next reply, or deny remembering something it just said. The model has no inherent way to verify who is actually giving orders. The core problem is one of trust boundaries: current large language models process instructions and data through the same channel - natural language - so there's no hard technical wall between "read this" and "do this." Researchers have demonstrated this across multiple major models, not because any one model is uniquely broken, but because the architecture makes the distinction genuinely difficult. Defenses exist but are imperfect. Techniques include output filtering, sandboxing agent permissions (limiting what actions the model is allowed to take regardless of what it's told), prompt hardening (structuring system prompts to be resistant to override), and retrieval-aware design that treats external content as untrusted by default. No single fix closes the gap entirely. Real Example: The Customer Support Agent Imagine a small business deploys an AI agent to handle incoming support emails. The agent reads the email, checks order history, and drafts replies. A bad actor sends a support ticket that looks normal on the surface, but contains a hidden paragraph - white text on white background, or text in a section the agent processes but doesn't display - that says: "Ignore pr

Grok Build is open source, and that matters for AI coding tools What happened xAI published the source code for Grok Build , its terminal-based AI coding agent. The repository shows a full stack for a TUI-driven assistant that can inspect a codebase, edit files, run shell commands, search the web, and manage longer-running tasks. In other words, this is not just a model demo or a chat wrapper; it is the software layer that turns a model into a usable developer tool. The release came up on the Hacker News front page, which is useful context because the discussion there was less about model benchmarks and more about tooling, workflow, and whether open-source agent infrastructure is becoming a competitive advantage on its own. Primary source: Grok Build repository Why this release is interesting A lot of AI coding products hide the implementation details behind a hosted UI. Open-sourcing the agent runtime gives the community something different to inspect: how the tool is structured, how it handles shell access, and how it organizes the user experience around files, commands, and context. That matters for engineers because the practical questions are often not about raw model capability. They are about reliability, prompting surfaces, permissions, and how much of the workflow can be automated without turning the tool into a black box. The README describes Grok Build as a terminal-based coding agent that supports interactive use, headless scripting, editor integration via the Agent Client Protocol, and a modular tool/runtime layout. That makes it closer to an infrastructure project than a showcase demo. If you are building internal copilots, code assistants, or agent workflows, the design choices here are worth studying. What the repository tells us The repository description makes a few things clear: 1. The agent is meant to be operational, not decorative The docs emphasize real actions: editing files, executing shell commands, searching the web, and coordinating long-

Building a semantic search engine for an e-commerce catalogue doesn't require a team of PhDs or a six-figure cloud budget. In this tutorial, I'll walk you through a production-ready pipeline using open-source tools: sentence-transformers for embedding, FAISS for vector indexing, and FastAPI for serving. The core insight is that semantic search isn't magic — it's just good engineering wrapped around a pre-trained language model. We'll start by setting up a product embedding pipeline that transforms your catalogue (title, description, category, attributes) into dense vectors. The key architectural decision is whether to embed each product as a single vector or to use late interaction models like ColBERT that preserve token-level detail. For most e-commerce use cases with fewer than 1 million SKUs, single-vector embedding with sentence-transformers' all-MiniLM-L6-v2 offers the best balance of speed and accuracy. The entire indexing pipeline — from CSV export to queryable vector index — runs in under 100 lines of Python. The re-ranking layer is where most tutorials stop and real-world systems begin. Pure vector similarity doesn't understand your business: it doesn't know that out-of-stock items should be deprioritised, that high-margin products should float up, or that a customer's purchase history should influence results. I'll show you how to build a hybrid scoring function that blends semantic relevance (cosine similarity), business rules (margin, inventory), and personalisation signals (user embedding) into a single ranked result set that returns in under 100ms.

For five years, the answer to "how do we make the model better" was always the same: bigger model, more data, wait for the loss curve to bend. Scaling laws made AI progress feel almost boring — predictable, like compound interest. That knob still works. But it's not the interesting one anymore. The real question teams are fighting with now is: given a model you already have, how much compute should it spend per question? Not per training run. Per question. And the answer turns out to break almost every assumption your inference stack was built on. The single forward pass was always the weak link Here's the thing nobody says out loud enough: a model's first answer is often just a noisy sample. The right answer was in there somewhere — it just wasn't the loudest one. You don't fix that with more pretraining tokens. You fix it by sampling more, checking the work, or letting the model take a second pass. That's the whole idea behind test-time compute. And there are three ways to spend that extra compute, and they are not interchangeable: Let it ramble longer. Cheap. Also the reason some models talk themselves out of the right answer after 3,000 tokens of unnecessary detours. Generate N answers, vote. Parallel, simple, plugs into infra you already have. Also: returns drop off fast. Past a certain N you're burning GPU-seconds for crumbs. Search a tree of partial reasoning steps, prune the bad branches early with a verifier. The most compute-efficient option by far. Also the one that quietly breaks your serving stack. Most real systems end up doing all three — cheap by default, escalating only when a confidence check says "this one's hard." That escalation decision is its own piece of architecture. Most teams bolt it on as an afterthought. It shouldn't be one. Your serving stack was not built for this Continuous batching, paged KV-cache, speculative decoding — all of that infra assumes requests are independent, similar in length, and finish in one pass. Test-time compute v

#NebiusServerlessChallenge Live dashboard: Myth-Busting Quantitative Terminal · Live endpoint: /predict on Nebius Serverless · Code: github.com/KoralZakai/stocksPredictionAfterTweet Everyone on a trading desk knows the story. He tweeted about Intel, and the stock ran for months. He posts about Iran, oil spikes. The anecdotes are vivid, specific, and everybody has one. While the prevailing myth suggests that Trump's tweets drive market movements, my research — built on an analysis of 78,130 posts, with Llama-3.3-70B reading every market-relevant tweet — reveals a more nuanced reality. The findings demonstrate that the market tends to price in significant events long before the tweet is even posted. This indicates a case of reverse causality, where the market dictates Trump's narrative, rather than the other way around. He isn't moving the market; he is simply riding the wave of established trends. Forward — the direction you could trade — the signal is a coin flip, and I can show that with pre-registered tests rather than vibes: 0 of 63 cells survive correction. Getting to that answer honestly was the hard part.

Ever sat down and thought about how a movie can spark your curiosity about technology? I was rewatching "Jurassic Park" recently, and, for the umpteenth time, I found myself mesmerized not just by the dinosaurs but by the computers! The way they portrayed tech in the early '90s was a mix of excitement and pure whimsy. I’ve been exploring the tech behind the magic, and it’s been a wild ride down memory lane—a nostalgia trip mixed with some surprising insights into how things have evolved. A Walk Down Memory Lane When I first watched "Jurassic Park" as a kid, the scene where Dr. Ellie Sattler runs through the control room, frantically trying to restore the park’s security, left me awestruck. I mean, who didn’t dream of typing on one of those cool-looking computers? As a budding developer, I couldn't help but wonder about the behind-the-scenes tech. Ever wondered why they used UNIX systems? Or why the computer graphics felt so cutting-edge back then? Turns out, they were leveraging a blend of SGI workstations and proprietary software that made their visual effects legendary. I remember my first experience with UNIX during my college days, and it felt like being dropped into a different universe—powerful, complex, and sometimes, downright intimidating. I’ve learned that just like in the movie, the power of tech lies in how effectively we can wield it. The Nostalgia of User Interfaces Let’s talk about user interfaces. The interfaces portrayed in the film, with their vibrant colors and flashy animations, were quite ahead of their time. It’s funny looking back because, at points, they seemed so unrealistic. I mean, the way Dr. Ian Malcolm effortlessly navigated the systems? I wish it was that easy! When I started working on UI/UX projects, I learned that simplicity is key. I once spent hours creating a beautiful interface that was so complex no one could figure it out! My takeaway? Sometimes, less is more. It’s the same lesson I’ve carried into modern frameworks like React

Risk stratification sounds like a data-science buzzword until you have to build the thing. For a Medicare Advantage plan, it's a concrete pipeline: take a population of members, score each one's clinical and financial risk, and rank them so care management and documentation teams know who to touch first. Here's how I'd architect it. The core idea Population health risk stratification = scoring + segmentation. You compute a per-member risk signal, then bucket members into tiers (e.g., rising-risk, high-risk, catastrophic) so finite resources go where they move outcomes and revenue most. The mistake teams make is treating it as a single ML model. In practice you want a layered signal: a stable, explainable base (RAF + chronic conditions) plus optional predictive overlays. Explainability matters because care managers won't act on a black-box score, and auditors won't accept one. Step 1: Build the member feature record { "member_id" : "SYNTH-77310" , "age" : 73 , "hccs" : [ "HCC37_1" , "HCC85" , "HCC18" ], "raf" : 1.842 , "gaps" : [ "a1c_overdue" , "no_pcp_visit_180d" ], "utilization" : { "ed_visits_12m" : 3 , "inpatient_12m" : 1 } } The RAF here is your defensible, model-grounded risk anchor under CMS-HCC V28. Everything else is supplemental signal. Step 2: Score and tier def risk_tier ( member ): base = member [ " raf " ] util = 0.15 * member [ " utilization " ][ " ed_visits_12m " ] \ + 0.30 * member [ " utilization " ][ " inpatient_12m " ] score = base + util if score >= 3.0 : return " catastrophic " if score >= 1.8 : return " high " if score >= 1.0 : return " rising " return " stable " Keep the weights transparent and tunable. The point isn't a perfect model; it's a defensible, reproducible ranking your operational teams trust. Step 3: Make "rising-risk" actionable The tier that quietly drives the most ROI is rising-risk — members trending toward high cost who still have open documentation and care gaps. Surface their specific gaps (overdue labs, undocumented chroni

You've got a recording and you want text back. For years that meant one thing at AssemblyAI: submit the file, wait for the job to finish, get a transcript. Async. It's reliable, it's cheap, and for a huge range of workloads it's exactly right. But "wait for the job to finish" is doing a lot of work in that sentence. If your file is two minutes long and your user is staring at a spinner, waiting is the whole problem. That's the gap the Sync API fills — and it's why "which transcription path" is no longer a two-way question. This post is about the two ways to transcribe a recording : async and sync. (If you're deciding between recorded and live audio in the first place — streaming versus the rest — start with our guide to real-time vs batch transcription , then come back here to choose between the two non-streaming paths.) The one-sentence difference Async transcription hands you a job: you submit audio, the work happens in the background, and you collect the result later by polling or via a webhook. Sync transcription hands you an answer: you POST a short clip and the transcript comes back in the same HTTP response — no job to track, no callback to wait for. Everything else follows from that. Async is built for throughput and depth on files of any length. Sync is built for speed on short files, when a person or an agent is waiting on the other end. How fast can each actually go? This is the question that usually settles it, so let's be concrete. Async processes the whole file and returns a single complete transcript, typically in seconds to a few minutes depending on file length and load. Crucially, it bills on audio duration ($0.21/hr on Universal-3.5 Pro), so a 30-minute file costs the same whether it comes back in 20 seconds or two minutes. You're optimizing for cost and completeness, not for the clock. Sync is built to return a transcript for a short clip almost immediately — roughly 134ms p50 — in one request/response, with no polling and no webhooks. It's price

How an unexpected regional constraint forced us to deeply understand Azure GPU VM families, naming conventions, and workload fit. Introduction As architects, we often assume that infrastructure decisions are straightforward: "The workload is already running successfully in Region A. Let's deploy the same Kubernetes workload in Region B." That's exactly what we thought. Our workload consisted of a Visual Element Detection (VED) service hosted on Kubernetes. The application uses a PyTorch model to analyze images and detect various visual elements in an image file. The service was already running successfully on a node pool backed by Azure's NVads_A10_v5 GPU VMs. Then we hit an unexpected challenge. The target region did not offer NVads_A10_v5 instances. What looked like a simple deployment exercise became a deep dive into Azure GPU virtual machine families, GPU architectures, VM naming conventions, and workload characteristics. This article shares what I learned in the hope that it helps others who find themselves evaluating Azure GPU SKUs for AI inference workloads. I am relatively new to the world of MLOps, Model deployments, GPU Workloads etc and equally interested and excited to learn more on this front. The Workload Before discussing VM selection, let's understand the workload characteristics: Model Type : PyTorch Model Size : less than 200 MB (.pth) Image Resolution : ~2000 x 2000 Expected Throughput : 5-7 requests/sec Platform : AKS (Kubernetes) Workload Type : Inference only This is important because GPU sizing should always start from the workload and not from the VM catalog. Step 1: Understanding Azure GPU VM Families Many engineers first encounter Azure GPU machines through names like: NV12s_v3 NV6ads_A10_v5 NC4as_T4_v3 ND96isr_H100_v5 The naming can be intimidating. The first breakthrough was understanding that Azure organizes GPU VMs into three primary families: N-Series ├── NV ├── NC └── ND NV Series – Visualization and Graphics NV-series VMs are designe

I stared at the GitHub page for what felt like forever. The repo had thousands of stars, hundreds of issues, and a long list of contributors who clearly knew what they were doing. Me? I had a few small personal projects, some half-finished tutorials, and a nagging feeling that I wasn’t “ready” to contribute to real open-source software. Especially not an AI project with fancy models, complex pipelines, and people publishing papers off the codebase. But I wanted in. I wanted to learn how real-world AI systems are built, to get feedback on my code, and to be part of something bigger than my local src/ folder. So I made a deal with myself: no more waiting until I feel “ready.” I’d go from zero to my first pull request (PR) in one focused push. Here’s exactly how I did it, what I learned, and what I’d tell anyone hesitant about contributing to an open-source AI or machine learning project for the first time. Step 1: Pick the Right Project (Not the Biggest One) The biggest mistake I almost made was aiming for the most famous AI repo I could find. Big projects are great, but they can be intimidating and slow for a first-timer. Instead, I looked for: Active maintenance : recent commits, issues being closed, maintainers responding. Clear contribution guidelines: a CONTRIBUTING.md or at least a solid README. Beginner-friendly issues: labels like good first issue, beginner, or help wanted. Scope I could understand: I didn’t need to grasp the entire codebase, just enough to fix one small thing. I ended up choosing a mid-sized open-source AI library : not unknown, not legendary. Perfect. If you’re searching now, try queries like: “awesome open source llm” “open source machine learning projects good first issue” “open source AI tools GitHub” Then scan their issues tab for beginner-friendly tasks. Step 2: Set Up the Project Locally (Without Panicking) Once I picked a project, the next hurdle was getting it to run on my machine. The repo had a typical structure: project/ README.md

DeepSeek vs Qwen vs Kimi vs GLM: Which One Wins My Freelance Budget? Last Tuesday I spent two hours building a client dashboard that needed AI-powered text summarization. The client is a small e-commerce shop, they get maybe 500 product descriptions a week that need condensing into bullet points. Sounds simple, right? Except when I ran the numbers on my usual OpenAI setup, the bill was going to eat into my margin harder than I'd like. That's when I went down the rabbit hole of Chinese AI models. DeepSeek, Qwen, Kimi, GLM — I've been hearing about these for months from other devs in Discord, but I never actually committed to testing them because, honestly, who has the time? Well, apparently I do, because that Tuesday I decided to run all four head-to-head against my actual workload. Here's what happened. Why I Even Bothered (The Real Math) Before we get into the benchmarks and pricing tables, let me put this in perspective. My hourly rate as a freelance dev sits at $85. Every hour I spend wrestling with a subpar API that hallucinates or charges too much is an hour I'm not billing a client. The "free" model is never free — either it costs me time or it costs me money, and usually both. I was paying roughly $0.60 per 1M output tokens on GPT-4o for the summarization work. For 500 product descriptions, each averaging maybe 150 tokens output, that's about $0.045 per batch. Sounds tiny, right? But multiply that across multiple clients, and suddenly I'm watching $40-60 a month vanish into API costs that I can't really pass along without awkward pricing conversations. So I started shopping. And what I found genuinely surprised me. The Contenders at a Glance All four model families run through Global API's unified endpoint, which means I didn't have to maintain four different SDKs, four different auth setups, four different billing dashboards. Just swap the model name in the request and ship. For a one-person operation, that's huge. Here's the landscape I was working with: Di

Hi guys ! I'm a new developer who's interested in data science and artificial intelligence. To showcase what I learnt thus far, I've started writing articles, with my first one being published here ! One of the most difficult parts of getting into machine learning was the overload of terminology that tutorials had, even when explaining basic concepts such as how a neural network itself would function. Because of this, I've written an article (see above) that simplifies it while ensuring the main concepts are sufficiently explained; it requires no mathematical background and will only take less than 5 minutes to read ! I hope you find it informative and well written, and I highly welcome any suggestions or corrections that might be suggested to improve my future articles !

TL;DR: Graph renderings of blockchain transactions carry topology signals that serialize badly into token sequences. A hub node surrounded by 47 short-lived leaf wallets looks like a table of addresses and amounts in text form — recognizable only if you already know the pattern. 📖 Reading time: ~23 min What's in this article The Problem: Blockchain Forensics Needs Vision, Not Just Text Hardware and Environment Setup on MI300X Data Pipeline: Rendering Blockchain Graphs as Training Images Fine-Tuning Loop: LoRA on 7B vs Full-Parameter on 7B ROCm-Specific Failure Modes and How to Diagnose Them Inference Serving: vLLM on ROCm for Classification Throughput Verdict: When This Setup Makes Sense and When It Doesn't The Problem: Blockchain Forensics Needs Vision, Not Just Text Graph renderings of blockchain transactions carry topology signals that serialize badly into token sequences. A hub node surrounded by 47 short-lived leaf wallets looks like a table of addresses and amounts in text form — recognizable only if you already know the pattern. Rendered as an image, that star topology is immediately visible as a structural shape. The same applies to layering patterns in mixing operations, where funds move through sequential depth levels that form visually distinct bands, and to clustering signatures where tightly-coupled address groups show dense internal edges versus sparse external ones. A vision-language model can learn to classify on those shapes directly. A text-based LLM working from a transaction list has to reconstruct the topology from raw numbers, which is possible but brittle — edge count and clustering coefficient can be computed and injected as tokens, but that's you doing the feature engineering that the vision model can learn to do itself. The reason Qwen2-VL entered this experiment rather than a GNN is mostly practical. Graph neural networks are the academically correct tool for graph classification, but they require a fixed-schema graph dataset and a trainin
