The Competition Over "Which AI Model Is Smartest" Is Over.

10 Architectures in 8 Weeks Between January and February 2026, something unprecedented happened in the AI landscape. Ten major open-weight LLM architectures were publicly released in just eight weeks. Here's what the numbers look like: Model Total Params Active Params Performance Level GLM-5 (Zhipu AI) 744B 40B Matches GPT-5.2 and Claude Opus 4.6 Kimi K2.5 (Moonshot AI) 1T 32B Frontier-class at release Step 3.5 Flash 196B 11B Outperforms DeepSeek V3.2 (671B) at 3x throughput Qwen3-Coder-Next 80B 3B Approaches Claude Sonnet 4.5 on SWE-Bench Pro MiniMax M2.5 230B N/A #1 open-weight on OpenRouter by usage Nanbeige 4.1 3B 3B 3B (dense) Dramatically outperforms same-size models from 1 year ago The key source: Sebastian Raschka's analysis, "A Dream of Spring for Open-Weight LLMs" (February 25, 2026). This isn't incremental progress. This is a phase transition. The Performance Gap Has Vanished Let's be precise about what "vanished" means. GLM-5 scores 77.8 on SWE-bench Verified. Claude Opus 4
