The first half of June 2026 saw an unprecedented surge in open-weight AI model releases, with over 25 new models launched across various domains including LLMs, image generation, and video. Key proprietary releases included Anthropic's Claude Fable 5 and Claude Mythos 5, OpenAI's GPT-5.6, and Google DeepMind's Gemini 3.2. The open-weight landscape was equally dynamic, featuring Qwen 3.7, DeepSeek V4.1, GLM-5.1, and MiniMax M3, alongside NVIDIA's Cosmos 3 for video simulation and an agentic framework called OpenClaw.
