not much happened today

**Google** rapidly released **Gemini 3.7 Flash** just three weeks after 3.6 Flash, targeting coding, web development, knowledge work, and agentic workflows with a 50% introductory price cut and improved benchmark scores like **DeepSWE 65.3%** and **Code Arena Elo 1588**. The update quickly integrated across multiple platforms including Gemini API and Android Studio, with independent benchmarks confirming performance gains. Meanwhile, **DeepSeek** open-sourced **DeepSeek Harness** under MIT license as a developer preview, focusing on architecture innovations like KV-cache-aware append-only history semantics and treating the harness as an OS/runtime substrate for recursive improvement. **Arcee** also open-sourced **NAC** under Apache 2.0, designed for long-running asynchronous tasks and powering significant code pipelines, enabling orchestration from phones or delegation via Codex/Claude.
