Open weights are table stakes now So here's the boring infra nobody wants to tweet about, also open⚡️ Things we've open sourced: — CubeSandbox, per-conversation sandboxes with browser, code, shell and file access, spun up and torn down for you — Agent Memory, a shared memory layer across your agents, and now across your teammates' agents too Things we've upstreamed: — RoCE optimizations for DeepSeek's DeepEP, doubling throughput on commodity networks, with 30% carrying back to InfiniBand — FlexKV, tiered KV cache offloading, now in NVIDIA Dynamo, vLLM and TensorRT-LLM mainlines All four are searchable by name, repos and docs. Pull requests welcome, and so are complaints 🛠️

Open weights intelligence advanced today with the release of Kimi K3. The gap between the leading proprietary and open weights models is now just 4 points on the Artificial Analysis Intelligence Index, the smallest it has been since the GLM-5 release in February @Kimi_Moonshot's Kimi K3 scores 57 on the Artificial Analysis Intelligence Index. Only two labs have higher-scoring models: @AnthropicAI, with Claude Opus 5 at 61 and Claude Fable 5 at 60, and @OpenAI, with GPT-5.6 Sol at 59.

Open weights models really accelerated! > Qwen-3.8 (2.4T), “second only to Fable 5” > Kimi-K3 (2.8T), “only behind Claude Fable 5 Max and GPT-5.6 Sol Max” > GLM-5.2 (753B): remarkably efficient and capable. The demand we’re seeing from Databricks customers is wild. This is super exciting.

OpenClaw signed @Microsoft’s Open Weights and American AI Leadership letter. Open weights protect user choice and enable people to run, study, and build AI on their own terms.

Tomorrow is a big day - Kimi K3 open weights will drop - move sonnet and Terra workloads to K3 - fine tune frontier models to create your custom model - open weights AI will truly be only a few points behind OpenAI and Anthropic 🚀🚀

Periodic reminder: Codex is a fully open source harness! You can audit exactly what happens to your prompt and how codex works its magic And if you want to you can also run any open weights model with it too ;)
