Alibaba's Qwen division has released Qwen 3.6 Plus Preview, a free multimodal model available via OpenRouter with a 1,000,000 token context window. The model claims stronger reasoning and more reliable agentic behavior compared to the 3.5 series, with particular strength in coding and complex problem-solving tasks.

OpenAI has released GPT-5.4 mini and GPT-5.4 nano, compact models optimized for coding and subagent tasks. The new models deliver significant performance improvements—GPT-5.4 mini reaches 54.4% on SWE-Bench Pro versus 45.7% for GPT-5 mini—but cost 3-4x more per input token than their predecessors.
