Theo open-sources tsc-rs: Opus 5.5 ported the TypeScript 7 compiler to Rust in two weeks for ~$24K, type-checking ~1.6x faster than the Go version
Theo (T3) open-sourced ts-rust (npm: tsc-rs), a Rust port of Microsoft's Go-native TypeScript compiler, checker and language server. Months of GPT-5.6 Sol / GPT 6 Astra runs cost over $400K in API-priced tokens and stalled near 84% compatibility; Claude Opus 5.5 restarted from scratch, reached a working v0 in 10 hours and finished in two weeks for about $24,047. All 181,711 ported Go tests pass, it type-checks 1.61x faster than tsc 7 (geometric mean over six open-source apps), ships Effect diagnostics built in and has a WASM build.

OpenCode team ships Hex 3.0 stable: local voice dictation for Mac, Windows and Linux, built for talking to coding agents
Anomaly, the company behind open-source coding agent OpenCode, shipped Hex 3.0 stable: hold a shortcut, speak, and the text is pasted at your cursor. Recognition runs on-device, local model memory drops from about 900 MB to about 160 MB, and it adds vocabulary hints, a hex CLI and optional OpenCode rewriting.

OpenAI Details Pando, Its In-House Git Backend: Median Push Latency Down Nearly 5x, Nearly 1 PB Served Daily, Built With Codex in 10 Weeks
On November 2 OpenAI published "Scaling Git at OpenAI", describing Pando, a Git-compatible backend it built for its monorepo. Per OpenAI, Pando cut median push latency by nearly 5x (about 80%), now delivers nearly a petabyte of Git data per day, and has served more than 57 TB in a single hour. It is written in Rust, its core was designed by one engineer and implemented by teams of Codex agents, and it went from kick-off to production in 10 weeks, serving production traffic since April. The trigger: Codex multiplied parallel branches and pushes, and the old system's reliability at times fell below 90%.
