Anthropic Is Now the Most Valuable AI Startup. Here's the Developer's Read.

on may 28 anthropic announced a $65 billion series h round at a post-money valuation of about $965 billion, which makes it, on paper, the most valuable ai startup in the world. the round was led by altimeter capital, dragoneer, greenoaks and sequoia, on top of earlier hyperscaler commitments that included around $15 billion with $5 billion of it from amazon. the headline everyone ran with is that anthropic passed openai. that part is true, but the comparison is messier than the headline, and the more interesting story is what is generating the number. i build small dev tools and write comparison content, and a lot of what i ship runs on top of anthropic's models. so when the company that makes the tools i depend on nearly touches a trillion dollars, i do not read it as a sports score. i read it as a question about whether the thing i am betting on is durable, and what i should do differently because of it. here is the honest version of both. the number, with the caveats intact the $965 billion figure is consistent across cnbc, axios, morningstar, al jazeera and euronews, so i trust it. what i would not do is state the gap over openai as a precise fact, because the sources do not agree on openai's number. axios pegged openai's most recent valuation at $730 billion. other outlets put it closer to $850 billion off a record round earlier in the year. either way anthropic is ahead right now, but "ahead by $115 billion" and "ahead by $235 billion" are different sentences, and anyone quoting one as gospel is rounding away the uncertainty. the safe claim is the one i will make: as of late may 2026, anthropic is the most valuably-priced private ai company, and it got there fast. the reporting has it roughly tripling from a $380 billion mark in february. the part that matters more to me is the revenue. anthropic crossed a $47 billion run-rate earlier in may. that is the line that turns a valuation from a vibe into something with a floor under it. you can argue about whether $

A free model that runs 4x faster on your own GPU — and two more shifts for builders

A free model that runs 4x faster on your own GPU — and two more shifts for builders Three things landed for builders at once: a free open model that generates text far faster, a more autonomous Codex, and Anthropic owning up to a model that was quietly holding back. Two of them you can act on right now. Here's the 2-minute video version if you want the quick pass first: 1. Google shipped DiffusionGemma — a free open model that runs 4x faster Google released DiffusionGemma , an open-weights model that uses text diffusion instead of standard autoregressive decoding. Instead of generating one token at a time, it generates whole blocks in parallel. It writes blocks of 256 tokens at once , for up to 4x faster generation on a dedicated GPU. It hits 700+ tokens per second on a single RTX 5090 , and fits in 18GB of VRAM quantized — inside consumer GPU limits. It's a 26B Mixture-of-Experts (only 3.8B parameters active), ships under Apache 2.0 , and runs natively in vLLM . The tradeoff Google states openly: output quality is lower than standard Gemma 4, so it's a speed play, not a quality play. Why it matters: this is a fast, free, local draft model you can run on your own hardware. Use it for low-latency drafts and agent loops, then route the hard calls to a stronger model. No inference bill for the cheap 80%. 2. OpenAI gave Codex web search and autonomous goals OpenAI shipped a major Codex update that pushes it further toward an autonomous agent. Code mode can now call web search directly , even from nested JavaScript tool calls — so it can look up current API docs mid-implementation. Goal mode is generally available across the Codex app, the IDE extension, and the CLI. Appshots (macOS) attach an app window to a Codex thread with a hotkey, and MCP tool schemas now preserve oneOf / allOf for richer connectors. Why it matters: Codex can research and chase a goal on its own across every surface. Still — hand it a clear, scoped goal in a branch. Full hand-offs go sideways witho

7 Things I Wish I Knew Before Scaling Next.js + Supabase to 100K Users

7 Things I Wish I Knew Before Scaling Next.js + Supabase to 100K Users Six months ago, we launched our SaaS with Next.js and Supabase. The stack was perfect for our MVP: fast development, great DX, and it just worked. Then we hit 10K users. Then 50K. Then 100K. Everything that worked beautifully at small scale started breaking. Database queries that took 50ms now took 5 seconds. Our Supabase bill went from $25/month to $800/month. Users complained about slow page loads. Here's what I wish someone had told me before we started. 1. RLS Policies Are Not Optional (Even in Development) We skipped RLS in development. "We'll add it before launch," we said. Launch day came. We enabled RLS on all tables. The app broke in 47 different places. Queries that worked suddenly returned empty arrays. Inserts failed with permission errors. We spent 12 hours fixing RLS policies while users waited. What I'd do differently: Enable RLS from day one. Write policies as you create tables: CREATE TABLE posts ( id UUID PRIMARY KEY DEFAULT uuid_generate_v4 (), title TEXT NOT NULL , user_id UUID REFERENCES auth . users ( id ) ); -- Enable RLS immediately ALTER TABLE posts ENABLE ROW LEVEL SECURITY ; -- Write policies now, not later CREATE POLICY "Users can view own posts" ON posts FOR SELECT USING ( auth . uid () = user_id ); Test with RLS enabled. If it works in development, it'll work in production. 2. Database Indexes Are Not Premature Optimization "We'll add indexes when we need them." We needed them on day 3. Our posts feed query went from 50ms to 8 seconds as we hit 10K posts. Users complained. We scrambled to add indexes during peak traffic. The query: const { data } = await supabase . from ( ' posts ' ) . select ( ' *, profiles(*) ' ) . eq ( ' published ' , true ) . order ( ' created_at ' , { ascending : false }) . limit ( 20 ) The fix: CREATE INDEX posts_published_created_at_idx ON posts ( published , created_at DESC ) WHERE published = true ; Query time dropped to 12ms. What I'd do di
