Google opened Gemini 4 Argon to paying Gemini app subscribers on October 13, and OpenCode disclosed on the 17th that OpenAI and Anthropic keys belonging to 1.4% of Console users may have been exposed.
Anthropic described on October 13 how it moved its monorepo off git onto an in-house version control system called Scion. Daily merges went from about 2,500 in May to 30,000 in September, hundreds of mirrors stopped holding, and the code is not being open sourced.
Google locked manual model switching in the Gemini app behind a paid plan, leaving 3.5 Flash-Lite as the only model its pricing page lists for free accounts, and GitHub shipped Claude Haiku 5.5 to five Copilot plans.
Anthropic opened OSS Scanner, a free vulnerability scan for open source, on October 8, 2026. Reports go out without human review and never become public advisories, and 363 application PRs piled up in three days.
Anthropic shipped Claude Haiku 5.5 on October 7. Input runs $0.10 per million tokens, a tenth of Haiku 4.5, but any prompt over 100,000 tokens pays $0.50, five times the headline rate.
OpenAI shipped GPT-6.1 Sol at DevDay on September 29 for the same $2 input price as its predecessor, and a day earlier Anthropic released Claude Sonnet 5.5 with 70.6% on Terminal-Bench.
Anthropic added Claude Mods to Claude Code v2.1.287 on October 1. Plugins now redraw the interface and intercept or pre-approve tool calls from inside the Claude Code process. There is no sandbox, mods can read environment variables and API keys, and the feature is on by default.
AWS opened in-region Claude inference on Amazon Bedrock in Seoul and Singapore on September 29. Requests never leave the Region, but the newest 5.5 generation is not on the list: Seoul gets Opus 5 and Sonnet 5, Singapore gets Sonnet 5 alone.
Anthropic released Claude Sonnet 5.5 on September 28. Pricing holds at Sonnet 5 levels, $2 per million input tokens, and Terminal-Bench 4.0 climbs from 10.3% to 70.6%, past Opus 5.5 at 66.4%.
xAI shipped Grok 4.7 on September 21 without raising the price, and the next day OpenAI cut GPT-6 Sol and Luna to half the previous rate while Anthropic released Claude Opus 5.5.
Disclosed September 17, Plugin4Shell shows Claude Code, Codex, GitHub Copilot, and Gemini CLI never verify they landed on the commit they pinned. Claude Code patched in June, Codex in August, Copilot still has no fix.
Anthropic released Claude Opus 5.5 on September 22. Input runs $4 per million tokens against Fable 5.1 at $10, and Terminal-Bench 4.0 climbs from 52.3% on Opus 5 to 66.4%.
