OpenAI has fully rolled out its ChatGPT agent to all Plus, Pro, and Team users and is building hype for the upcoming GPT-5, which reportedly outperforms Grok-4 and can build a cookie clicker game in two minutes. Alibaba's Qwen team released the open-source reasoning model Qwen3-235B-Thinking, achieving an 89% win rate over gpt4-0314 using a new RL algorithm called Group Sequence Policy Optimization (GSPO). Runway introduced Runway Aleph, a state-of-the-art in-context video model for editing and generating video content. Hugging Face highlights the growing momentum of open-source AI, especially from Chinese teams. Other updates include Kling's upgrades for image-to-video generation and Google's Imagen 4 Ultra being recognized as a top text-to-image model. Anthropic integrated Claude with Canva for branded visual designs but faces stability issues. The PyTorch team released optimized checkpoints for SmolLM3 to speed up inference.
