阿里巴巴推出了其新的Qwen 3.5模型系列，这是一个包含四款开源AI模型的家族，该公司表示这些模型以更低的成本就能媲美GPT-5 mini和Claude Sonnet 4.5。该系列包括一个轻量级的Flash变体和三个不同参数规模的混合专家（mixture-of-experts）模型。

Nous Research releases NousCoder-14B, an open-source coding model that benchmarks competitively against proprietary tools like Claude Code.

Nous Research releases a 14-billion-parameter coding model trained with reinforcement learning in just four days, publishing the entire training stack.
