Sarah Friar, CFO of OpenaAI, introduces a practical AI scorecard to measure ROI through useful work, cost per successful task, dependability, and return on compute.

Ask ten AI developers what tools they use, and you'll probably get ten different answers. The AI ecosystem is evolving so quickly that it's easy to believe you need every new framework, model, and application to stay productive. I don't think that's true. Over the past year, I've experimented with dozens of AI tools while building products, writing technical content, managing prompt libraries, and developing AI workflows. Along the way, my stack has become surprisingly simple. It's not built around the "best" tools. It's built around the tools that work well together. Here's the AI stack I rely on in 2026 and, more importantly, why each tool has earned its place. 1. ChatGPT: My Primary Thinking Partner ChatGPT is where most of my work begins. Not because it can do everything, but because it helps me think faster. I use it for: Brainstorming ideas Structuring articles Reviewing technical concepts Exploring architectural trade-offs Refining prompts Research assistance I rarely expect the first response to be perfect. Instead, I treat it like collaborating with a knowledgeable teammate who accelerates my thinking. 2. Cursor: My AI-Powered Development Environment When it's time to write code, I move into Cursor. Its strength isn't just code generation. It's understanding the context of an entire project. Whether I'm building a FastAPI backend, integrating APIs, or refactoring an existing codebase, having AI directly inside the editor removes a huge amount of friction. The less I switch between applications, the more productive I become. In fact, one of the biggest lessons I've learned is that adding more AI tools doesn't automatically improve productivity. Sometimes it has the opposite effect. I explored this idea in The Hidden Cost of Using Too Many AI Tools , where I explain why a smaller, well-integrated stack often outperforms a collection of disconnected applications. 3. GitHub: The Source of Truth Every project eventually ends up in GitHub. Not just source code. I

A tutorial series, DEV.to blog series — from your first HTML element to production-grade User Interfaces, all in pure Python. Modern Python web frameworks force developers into a split workflow: business logic lives in Python files with full IDE support, while presentation logic is exiled to template files that offer none of it. Template languages like Jinja2 introduce their own syntax for conditionals, loops, and variable access — syntax that your linter cannot check, your type checker cannot verify, and your debugger cannot step through. Every context variable passed across that boundary is a potential KeyError waiting to surface at runtime. Probo eliminates this divide entirely by making HTML a native Python construct — written, validated, and refactored with the same tools you already use for the rest of your codebase. PART 1: Introduction to Probo — Write HTML Entirely in Python What is Probo? Probo is a Python-first, declarative UI rendering framework . Instead of writing HTML in .html files or using template languages like Jinja2, you write everything in pure Python. No template files. No string concatenation. No f-strings full of angle brackets. Just Python functions and classes that are your HTML. The Two Flavors of Every Tag Every HTML tag in Probo comes in two forms: Flavor Example Returns Use Case Function (lowercase) div() , h1() , p() Rendered HTML Quick rendering, lightweight Class (uppercase) DIV() , H1() , P() SSDOM tree node Tree manipulation, streaming from probo import div , DIV # Function: returns a string immediately # return_list=True html_string = div ( " Hello World " ,) # → "<div>Hello World</div>" # Class: returns a tree node, call .render() to get the string node = DIV ( " Hello World " , Id = " main-title " ) # Because it's a Node, you can manipulate it dynamically node . add ( div ( " Subtitle added later! " )) html_string = node . render () # → '<div id="main-title">Hello World<div>Subtitle added later!</div></div>' Note: by adding ret

In this article, we're going to explore Event Schema evolution with Event versioning 10. Event Schemas Will Eventually Change No event schema stays the same forever. As businesses grow, regulations shift, products gain new features, and processes become more complex, the data shared between services must evolve as well. This evolution is not optional—it is a natural consequence of a system adapting to changing requirements. Many teams initially assume they can simply update an event whenever needed. This assumption may hold when there is only one producer and one consumer, but real-world systems rarely remain that simple. Over time, multiple consumers emerge, each with its own responsibilities and release cycles. A typical system often looks like this: OrderConfirmed | +------------------+-------------------+ | | | v v v Inventory Billing Notification | v Analytics | v Customer Insights Each consumer evolves independently. Some services may deploy updates weekly, while others might release changes quarterly. In some cases, consumers may even belong to external teams with entirely different priorities and timelines. Because of this, producers cannot assume that all consumers will upgrade simultaneously. Schema evolution, therefore, is not just about modifying data structures. It is fundamentally about maintaining compatibility across independently evolving systems. Compatibility Is More Important Than Version Numbers When discussing schema evolution, teams often focus immediately on versioning. While versioning is useful, compatibility is far more critical. Without compatibility, versioning alone cannot prevent system breakage. Consider the following event: { "orderId" : "ORD-1001" , "customerId" : "CUS-501" , "totalAmount" : 249.99 } Now imagine a new requirement introduces currency. One approach might replace the existing field entirely: { "orderId" : "ORD-1001" , "customerId" : "CUS-501" , "amount" : { "value" : 249.99 , "currency" : "USD" } } Although the data mo

This is the next big thing! I've been working on Moonlight AI for almost 6 months now and today I have big news. Automated Applications . That's right, Moonlight AI will have automated applications for the 2.0 version! What is Moonlight AI? Moonlight AI at first, was a project that was aimed to compete with Upwork. That definitely didn't work out even at the development phase so I had to pivot to another project. A month after the conception of the original version, I met a potential co-founder for a new initiative. Moonlight has been repurposed to be a capabilities mapping engine based on worker experience. We used a resume parser and a local LLM to map the capabiities based on skills and job experience alongside Github integration to use as proof of work. The project ultimately didn't work out, the potential cofounder was MIA so my only recourse was to rewrite Moonlight AI to be another thing, which ended up being a glorified job board which is how it works now. The Development Process Moonlight AI was vibe-coded in a night. Modifications were done the same way with different LLM models. LLMs today are what I call an automated entry-level developer since juniors is the wrong term because juniors at least have from 1-3 years of experience in the professional landscape and are more than just coding monkeys, where as entry-levels are just that, developers with 0 years of experience. Today, Moonlight AI should be done the correct way: reading the code and writing it too. Why let an LLM to do my job as well as think for me? DO YOU WANT ME TO GET ALZHEIMER? BECAUSE THAT'S HOW YOU GET ALZHEIMER! Anyways, exercising the mind is very important, that's what make us humans. People today have an obsession with automating their lives completely and end up like the humans in WALL-E. End of rant. The Future (Conclusion) I don't know the future, but I envision Moonlight AI to be a tool to make unemployed people lives a little less unbearable. I know how frustrating is to use a jo

Hi everyone! I’m a developer at the beginning of my journey, and I’ve just finished working on a small project that brought me a lot of joy: Capybara Game. It’s a cute game where you feed your capybara and improve her happiness level. You can choose between 5 different types of food or pick your own snack. If the capybara likes the snack, her happiness level rises; if she doesn't like it, the happiness level falls. Your progress is saved automatically. Keep in mind that your capybara gets hungry over time, so make sure to check back and feed her regularly! I went for a minimalist, cozy design. The interface is clean and intuitive, focusing on a relaxing user experience that lets the player focus entirely on the capybara. I built this project using HTML, CSS, and JavaScript. Hope you're interested in playing! You can do it here: Play the game here I’d love to hear your thoughts! If you have any ideas for new features or if you find any bugs, feel free to let me know in the comments.

By default, whenever you request a machine learning model, the underlying architecture saves gigabytes of tensor data into a hidden directory located directly inside your home folder ( ~/.cache/huggingface ). Because standard bare metal and virtual cloud configurations typically isolate the root operating system on a smaller, highly optimized boot drive, pouring 140GB+ of raw weights into the home folder guarantees absolute storage exhaustion. Here is the engineering blueprint to fix it cleanly on Linux. The Cache Location Trajectory When attempting to solve this problem, avoid outdated tutorials recommending deprecated parameters like TRANSFORMERS_CACHE . Environment Route Support Status Architecture Impact HF_HOME Active Master Route Safely redirects all models, datasets, and core assets globally. TRANSFORMERS_CACHE Deprecated Warning Fails to capture datasets and will be removed in version 5.0. HUGGINGFACE_HUB_CACHE Deprecated Warning Legacy routing path that creates unnecessary diagnostic warnings. 🛑 The Symlink Security Risk Creating symbolic links (symlinks) to trick the OS into routing files elsewhere is a common anti-pattern. Mapping these links improperly or running your workflow with elevated rights introduces privilege escalation vulnerabilities, compromising container and host security. Step 1: The Permanent Environment Override To change your Hugging Face cache directory on Linux permanently, target an expansive secondary storage array instead by appending a direct master route into your user profile configuration: # Create a dedicated folder inside your secondary storage array sudo mkdir -p /mnt/massive_drive/ai_model_cache sudo chown -R $USER : $USER /mnt/massive_drive/ai_model_cache # Append the master environment variable to your bash profile echo 'export HF_HOME="/mnt/massive_drive/ai_model_cache"' >> ~/.bashrc source ~/.bashrc Step 2: The Python Import Order Mandate If you declare your custom storage location programmatically inside an application

Perimenopause has entered the chat. Perimenopause—and its better-known relative, menopause—used to be considered taboo. Not anymore, thanks at least in part to TV doctors and social media influencers. Perhaps it’s my age, but these days, both my algorithm and my conversations with friends increasingly swing toward perimenopause. Menopause is defined as the life stage that…

A practical, end-to-end walkthrough of taking a read-only slice of an enterprise source system and exposing it to an AI agent as a set of Model Context Protocol (MCP) tools — using Azure Logic Apps, API Management, and Agent Foundry. All identifiers below are placeholders; swap in your own. The goal We wanted a simple outcome: a user asks a business question in plain language and gets a straight answer — no dashboards, no field names, no training on the underlying system. That means an AI agent with safe, read-only access to a backend system of record, exposed as discrete tools the model can call. The constraints shaped every decision: Read-only. The agent can retrieve and analyze, never write. Safe. Records in most business systems contain free text (notes, subjects, descriptions) that could carry prompt-injection payloads. Tool output must be treated as data, never instructions. Composable. The agent should see many small, well-described tools — "list records", "aggregate by category", "record change history" — not one giant "query the system" tool. The architecture Five layers, one direction of flow: Agent (Agent Foundry) │ MCP (JSON-RPC over HTTP) ▼ MCP server (API Management) │ REST operation per tool ▼ API gateway (API Management) │ single POST, routed by body ▼ Tool executor (Logic App) │ OAuth token + REST calls ▼ Source system (REST API) The key design choice: one backend endpoint, many logical tools. The Logic App exposes a single HTTP trigger that accepts { "tool": "records.list", "parameters": { ... } } and routes internally. API Management then fans that single endpoint out into many named operations, and its MCP feature turns those operations into agent tools. This keeps the backend trivial to maintain while the agent still sees a rich, typed tool catalog. Step 1 — Design the tools Start from the questions , not the schema. A useful toolset usually falls into a few families: Records: list / get / search / filter for the core business entities. Activity

GitHub announced enterprise-managed OpenTelemetry export for Copilot activity from VS Code and Copilot CLI on July 8, 2026. Primary source: GitHub Changelog, July 8, 2026 . Export availability is only the start. The receiving collector becomes an enterprise ingress point. This is an unexecuted operating plan; signal types, attributes, endpoint requirements, and controls must be checked against current GitHub documentation. Isolate the path managed clients -> private telemetry ingress -> dedicated OTel Collector pool -> field policy + bounded queue -> dedicated backend dataset Do not point every developer client directly at the primary observability backend. Give the collector write-only destination credentials, separate its dataset from production application telemetry, and define retention before rollout. Isolation is not anonymity. Stable user, device, organization, or repository identifiers may still be sensitive. Start with a field budget Category Initial policy Product and version Keep bounded values Operation and status Keep documented enums Timing and counts Keep numeric measures Raw prompts or generated code Drop by default File paths and repository URLs Drop or transform after review User identity Prefer scoped pseudonymous identity Free-form errors Drop raw text; keep reviewed classes These categories are recommendations, not a description of GitHub's payload. Inspect a restricted canary before naming actual keys. processors : memory_limiter : check_interval : 1s limit_mib : 512 spike_limit_mib : 128 attributes/field_budget : actions : # Illustrative keys only; replace after payload review. - key : user.email action : delete - key : file.path action : delete - key : command.arguments action : delete batch : send_batch_size : 512 timeout : 5s Verify processors against the chosen Collector distribution. A valid startup does not prove that records satisfy policy. Drill three failures Backend outage: block the exporter. Retries must be bounded, queue growth vi

OpenAI published an audit of SWE-Bench Pro on July 8, 2026 and estimated that roughly 30% of its tasks are broken. The reported issues make a familiar leaderboard assumption unsafe: every task in the denominator is a valid, equally interpretable trial. Primary source: OpenAI, “Separating signal from noise in coding evaluations” . The operational response should not be “ignore all benchmarks.” It should be: version task validity, preserve disputed cases, and publish how conclusions change across plausible denominators. Model task state separately from model result task validity: unreviewed | valid | broken | disputed model result: pass | fail | infrastructure_error | missing Never convert infrastructure_error to model failure without reporting that policy. Never delete broken tasks while retaining an old score label. A row needs provenance: { "task_id" : "repo-issue-17" , "dataset_revision" : "sha256:..." , "harness_revision" : "git:..." , "model_config" : "immutable-config-id" , "validity" : "disputed" , "result" : "pass" , "review_revision" : 3 , "evidence" : [ "fixture.log" , "review.json" ] } Publish three denominators Let: P_v , N_v : passes and total among reviewed-valid tasks; P_a , N_a : passes and total across all attempted tasks; D : disputed tasks. Report: valid-only score = P_v / N_v all-attempted score = P_a / N_a uncertainty interval = score if every disputed task hurts conclusion .. score if every disputed task helps conclusion This interval is not a statistical confidence interval. It is a sensitivity bound for unresolved task validity. A tiny sensitivity calculator #!/usr/bin/env python3 import json , sys rows = [ json . loads ( line ) for line in open ( sys . argv [ 1 ]) if line . strip ()] valid = [ r for r in rows if r [ " validity " ] == " valid " ] disputed = [ r for r in rows if r [ " validity " ] in ( " unreviewed " , " disputed " )] attempted = [ r for r in rows if r [ " result " ] in ( " pass " , " fail " )] rate = lambda passed , total : pa

OpenAI introduced GPT-Live on July 8, 2026 and describes it as a full-duplex voice architecture: it can listen and speak at the same time. GPT-Live-1 and GPT-Live-1 mini are rolling out in ChatGPT Voice, while API availability was described as coming later. Primary source: OpenAI, “Introducing GPT-Live” . Full duplex changes the mobile failure surface. The app may hold microphone input, play output, detect interruptions, and continue background work concurrently. A polished desk demo does not answer what happens when a phone call arrives, Bluetooth disconnects, the app backgrounds, or permission changes. This is the test plan I would run before shipping a full-duplex voice workflow. It is a plan, not a report of measured GPT-Live API behavior. Record the environment device : " physical device model" os : " exact OS version" app_build : " immutable build" voice_model : " product/model label visible during test" audio_route : " speaker | wired | bluetooth" network : " wifi | 5g | constrained" battery_start : " percent" low_power_mode : false microphone_permission : granted background_permission : " record actual setting" A result without device, route, and network context is difficult to reproduce. Define observable states idle -> connecting -> listening <-> speaking -> reconnecting -> paused_by_system -> ended -> error Track three channels separately: audio input — is the microphone active? audio output — what route is speaking? task state — is a delegated/background operation still running? The UI should never imply “listening” after the OS revoked microphone access. Interruption sequence Use a harmless scripted conversation and timestamp every event: T+00 connect on phone speaker T+10 user speaks while assistant is speaking T+20 switch to Bluetooth headset T+35 background the app for 30 seconds T+65 return to foreground T+80 trigger an incoming call or system audio interruption T+95 decline/end interruption T+110 disable microphone permission in Settings T+130 retu

OpenAI's July 14 guidance for managing AI investments recommends five moves: improve visibility into usage and spend, evaluate efficiency by outcome ROI, govern advanced workflows before scaling, fund workflows that compound, and match capacity to proven demand. Primary source: OpenAI, “How to manage AI investments in the agentic era” . The hard part is the denominator. “This agent used $800” says little. “This workflow cost $14 per accepted reconciliation, including review and rework” can support a decision. Here is a one-page ledger I would require for an agent pilot. Define one accepted outcome Do not start with tokens, seats, or tasks launched. Define the business state that counts after review. workflow : vendor-invoice-reconciliation accepted_outcome : " invoice matched, exceptions reviewed, result posted" owner : finance-ops pilot_window_days : 21 minimum_sample : 100 invoices quality_gate : false_postings : 0 exception_recall : " >= 0.98" reviewer_minutes_p50 : " <= 3" A generated draft is not an outcome if a person must rebuild it. An agent run is not successful if its result never enters the system of record. Capture the complete cost AI cost + orchestration and observability + human review + rework + incident handling + allocated implementation cost = total workflow cost Use a table with declared variables: Variable Meaning Example only C_model model and tool-call spend $600 C_platform workflow infrastructure $200 H_review reviewer hours 35 R_hour loaded reviewer rate $45 C_build pilot build cost allocated to window $2,000 N_accept accepted outcomes 850 total = C_model + C_platform + H_review * R_hour + C_build cost_per_accepted_outcome = total / N_accept With the illustrative numbers, total cost is $4,375 , or about $5.15 per accepted outcome. These are not benchmark claims; replace every value with measured data. Compare against the real baseline The baseline must use the same unit and quality gate: Metric Manual baseline Agent pilot attempted invoices
