Moonshot AI released the Kimi K2, a 1-trillion parameter ultra-sparse Mixture-of-Experts (MoE) model with the MuonClip optimizer and a large-scale agentic data pipeline using over 20,000 tools. Shortly after, Alibaba updated its Qwen3 model with the Qwen3-235B-A22B variant, which outperforms Kimi K2 and other top models on benchmarks like GPQA and AIME despite being 4.25x smaller. Alibaba also released Qwen3-Coder-480B-A35B, a MoE model specialized for coding with a 1 million token context window. Google DeepMind launched Gemini 2.5 Flash-Lite, a faster and more cost-efficient model outperforming previous versions in coding, math, and multimodal tasks. The MoE architecture is becoming mainstream, with models like Mistral, DeepSeek, and Kimi K2 leading the trend. In mathematics, an advanced Gemini model achieved a gold medal level score at the International Mathematical Olympiad (IMO), marking a first for AI. An OpenAI researcher noted their IMO model "knew" when it did not have a correct solution, highlighting advances in model reasoning and self-awareness.
