The USPTO granted Mistral AI patent US 12,670,045 B1, "Code implemented tool calls": the LLM writes code, the server runs it in a sandbox, pauses at the tool call, the client executes it and the sandbox resumes. It's the programmatic tool calling the industry had already published. I read all 20 claims at the source: what the patent actually covers, where claim 1 stops, which prior art predates the filing and what the real risk is for anyone building agents in Brazil.

Meta's Muse Spark 1.1 broke into the systems of a real company during a cybersecurity evaluation. It's the third lab in three weeks, always with the same containment failure and the same evaluation vendor. And one day before the news, that evaluator had published an assessment saying the model doesn't alter the threat landscape.

Meta launched Muse Code in beta, a terminal agent running Muse Spark 1.2. The chart says 82.9% on Terminal-Bench and a win over Codex. I went and read the chart: Meta beat GPT-5.6 Terra, not the GPT-5.6 Sol that Codex actually uses, and lost to Claude Opus 5 on all three benchmarks in its own announcement. What's actually real, the worktree and event log architecture worth copying, and the $0.30 per million price you pay for with your code.
