Agents

A heavy Tuesday. HN’s #1 is the formal end of Microsoft and OpenAI’s exclusive partnership and revenue-share — the AGI clause is now history. GitHub Copilot moves to usage-based billing (HN 532 pts, 408 comments). Mercor’s 4TB voice-sample leak puts 40k AI annotators on the public web. pgbackrest stops maintenance and the Postgres community begins migrating. Microsoft drops VibeVoice on MIT — a Whisper-class ASR model with diarization that runs on a Mac with one uv line. Two strong Japan picks: Matz’s own Ruby AOT compiler Spinel, and the CAMPFIRE GitHub-credentials breach postmortem.

Monday opens hot. HN’s #1 today is an AI agent that wiped a production database — its ‘confession’ (i.e. reasoning trace) is openly published and the 422-comment thread is required reading. OpenAI itself declares SWE-bench Verified saturated. Microsoft ships TypeScript 7.0 Beta — the compiler ported to Go, ~10x faster. mattpocock/skills tops GitHub Trending at +2,507 stars/day. The agent-skills-as-infrastructure phase has clearly begun.

DeepSeek V4 lands with two preview models that are basically frontier-grade at a fraction of the price; Hugging Face open-sources ml-intern, an ML-engineer agent that reads papers and trains models; Cloudflare ships a Git-shaped filesystem for AI agents; Anthropic doubles down on Japan via NEC; OpenAI publishes a serious GPT-5.5 prompting guide.

The GPT-5.5 dust settles and the interesting news moves one layer down the stack: Google puts PyTorch natively on TPUs (TorchTPU), ships Spanner Omni that runs on your laptop, and the Claude Code ecosystem keeps maturing with a code-search MCP hitting GitHub Trending.

GPT-5.5 ships, Anthropic posts a Claude Code postmortem, and Google Cloud Next debuts Gemini Enterprise Agent Platform — all on the same day. Plus a Bitwarden CLI supply-chain breach and Crawshaw’s ‘I am building a cloud’ manifesto.
