American companies are losing market share to chinese open-source companies! Anthropic’s coding market share on OpenRouter went from 46% in July down to 32% in a month the reason for it? Qwen3-Coder https://x.com/scaling01/status/1956858471682617553

There’s been a lot of Discourse about Qwen’s rejection of hybrid paradigm. “”Did DeepSeek fall for the hybrid meme?”” But hybrids make *so much sense* if you’re building a fast, economical SWE agent, which is exactly what 3.1 is for. It’s all been for Aider, Claude Code, MCPs. https://x.com/teortaxesTex/status/1958437173948023127

>V3.1-Base I guess this confirms they’ve moved on to hybrid models, Anthropic-style (and contra Qwen). I am not amused with how it works. But I was also disappointed with V2.5 (original), their merge of chat and code; ultimately, it worked. Another reason to expect V4, not R2. https://x.com/teortaxesTex/status/1957818879205351851

What if your agent uses a different LM at every turn? We let mini-SWE-agent randomly switch between GPT-5 and Sonnet 4 and it scored higher on SWE-bench than with either model separately. Read more in the SWE-bench blog 🧵 https://x.com/KLieret/status/1958182167512584355
I’m fine with this. The community largely agrees that lmsys isn’t a reliable proxy for real-world performance, and Sonnet consistently scores low because it doesn’t optimize for that benchmark. To me, this signals a shift from preference-based rewards to real-world rewards, and https://x.com/LucasAtkins7/status/1956435679229186353
Anthropic acquired Humanloop’s team to strengthen its AI testing and observability efforts The company also added memory to Claude, and a 1M token context window in Sonnet 4 for API use https://x.com/adcock_brett/status/1957111198115115164
The OpenAI Playground has improved a lot recently. I’ve been using it to test GPT-5 on new use cases. Watch how I use it to chat with internal docs via MCP tools. It uses the vector store feature too. Testing out the Prompt Optimizer and Evaluation features next. https://x.com/omarsar0/status/1956459233039233528
