    Andrej Karpathy Joins Anthropic to Run a Claude-Powered Pre-Training Team
    • OpenAI co-founder and ex-Tesla AI lead starts this week under pre-training lead Nick Joseph.
    • Mandate: stand up a new team that uses Claude itself to accelerate pre-training research — the bottleneck Anthropic just bought 220K H-class GPUs to push on.
    • Karpathy pauses his year-old education startup Eureka Labs to take the role.
    • HN front-page thread 'I've joined Anthropic' is the top developer story of the day.

    Cursor Composer 2.5 Matches Opus 4.7 and GPT-5.5 at One-Tenth the Price
    • Built on Moonshot's Kimi K2.5 checkpoint, with Cursor putting 85% of compute into extra training and RL on top.
    • 79.8% on SWE-Bench Multilingual and 63.2% on CursorBench v3.1 — within points of Opus 4.7 and GPT-5.5.
    • Priced at $0.50 / $2.50 per million input/output tokens, roughly a tenth of Anthropic and OpenAI's frontier tiers.
    • Trained on 25× more synthetic tasks than Composer 2, including 'feature deletion' rebuild puzzles.
    • HN reaction split between developers cheering open-base coding models and skeptics flagging benchmark gaming on Cursor's own evals.

    Anthropic Tells Investors It's About to Have Its First Profitable Quarter
    • Q2 revenue guided to $10.9B — more than double Q1's $4.8B, and more than all of 2025 combined.
    • Projected operating profit of $559M (excludes stock-based comp); last summer's investor deck said profitability not before 2028.
    • Growth rate ahead of historical peaks at Zoom, Google, and Facebook.
    • Disclosed inside an ongoing round that bankers now expect to value Anthropic above OpenAI.

    Anthropic Pays $300M+ for Stainless and Pulls It From Every Rival
    • Stainless's AI compiler generates the official SDKs for OpenAI, Google, Cloudflare, Runway, and Meta from OpenAPI specs.
    • Anthropic confirmed it will wind down hosted Stainless products and restrict the engine to internal teams.
    • Third acquisition in six months after Bun and Vercept; pairs with the Karpathy hire as a one-week talent + infra play.
    • HN reaction calls it 'somewhat anti-competitive' — rivals now have to rebuild SDK and MCP-server tooling from scratch.

    OpenAI Joins C2PA, Embeds Google SynthID, and Ships openai.com/verify
    • OpenAI becomes a C2PA Conforming Generator — every image from ChatGPT, the API, and Codex now carries signed provenance metadata.
    • Adds Google DeepMind's SynthID invisible watermark as the durable second layer that survives screenshots and re-encoding.
    • Public verification tool at openai.com/verify accepts any uploaded image and reports which signals are present.
    • At launch it only verifies OpenAI-generated content; cross-lab support depends on Anthropic and others adopting the same stack.

    DeepMind Plugs Project Genie's World Model Into Street View
    • Pick any U.S. address; Genie 3 generates a navigable, interactive scene grounded in Google's 280B-image Street View archive.
    • 60-second sessions at 720p; same engine Waymo already uses to train robotaxis on rare scenarios like tornadoes and elephants in the road.
    • Live globally for $200/month Google AI Ultra subscribers; the new $99.99 Ultra tier does not get access.
    • Still video-game quality, not photorealistic, and not yet physics-aware.
