Posted Oct 23, the 428B-total/23B-active multimodal MoE with 1M context ships with a DSpark draft head and serving recipes for SGLang, vLLM (day-0 images), and TokenSpeed, at roughly 233 GB of MXFP8 weights. It's not Apache or MIT: the MiniMax Community License requires a "Built with MiniMax M3.1-Flash" notice for commercial use and written approval above $20M in yearly revenue (license).
Announced Oct 22, agents can search Interchange's docs and call any API method in its sandbox to open, fund, and trade accounts, under a Docs Only, Read Only, or Read & Write key you approve in your browser. Each call swaps the agent's token for a 60 second one recorded on the action, and the command tool never retries on its own, so a timeout can't turn into a second trade…
Since Oct 22, the usage metrics API reports customer defined skills, custom agents, MCP servers, slash commands, and plugins by their configured names instead of other or custom , and lists up to 25 per record instead of five. Names come from Copilot CLI, the Copilot app, ACP integrations, and SDK based IDE agents (CLI 1.0.97+ or SDK 1.0.21+), and MCP counts still track connection attempts, not tool calls…
With Theorem, Claude patched the bugs it found and then produced about 180 million lines of Rocq proving those fuzz targets never crash on any input under 64 MB, checked by the Rocq kernel rather than human reviewers. The guarantee only covers single threaded static RISC V Linux binaries, and a subset of proofs plus a Claude skill for verifying your own code are public (proofs)…
Speaking at Grafana's ObservabilityCON, Katelyn Lesse said her roughly 200 person team, which runs Anthropic's core services and developer tools, no longer writes code by hand: engineers own system design and verification while Claude Code does the implementation, including a Python to Rust migration. Some test fixes already run with no human in the loop, and Anthropic is weighing letting agents change real codebases on their own…
Launched Oct 23, v2.0 averages Cognition's private FrontierCode v1.1 (graded on whether a maintainer would merge the change), Terminal Bench 4.0, and re graded SWE Atlas QnA AA across 290 tasks, so scores reset below v1.5. Claude Code with Opus 5.5 tops it at 61.7 for $11.42 per task, while Codex with DeepSeek V4.1 Flash scores 47.3 for $0.39 (announcement)…
