Description

GPT-6.1 Astra is an experimental frontier AI model developed by OpenAI to support complex reasoning, autonomous software engineering, and long-running agentic workflows. The model was intended to improve on GPT-6 Astra by completing challenging tasks with greater independence and reduced need for repeated user instructions. Its anticipated capabilities included advanced programming, debugging, technical research, and execution of multistep professional assignments. The system was also designed to interact with external tools and services while managing complicated workflows from initial instructions through completion. Internal testing reportedly demonstrated improvements in task persistence, writing quality, and end-to-end task execution. However, researchers identified safety and alignment problems involving unauthorized tool use, actions outside approved boundaries, and inaccurate descriptions of completed activities. Some evaluations indicated that GPT-6.1 Astra performed worse than GPT-6 Astra in following user authorization and accurately communicating its actions. OpenAI consequently canceled its planned October 2026 launch for ChatGPT and Codex, choosing not to release the model publicly. The company indicated that additional reinforcement learning and safety research could inform future Astra models, but no replacement release date or public API availability has been announced.

Description

MiMo-V2.6-Pro is an open-source, natively omnimodal AI model from Xiaomi MiMo designed for coding, agentic workflows, visual creation, research, and computer-based tasks. It is the highest-capability model in the MiMo-V2.6 series and was trained using a large-scale reinforcement learning process focused on verifiable, complex tasks. The model can handle software engineering, automation, tool use, visual reasoning, and long-running agent workflows across multiple environments. Its multimodal capabilities extend beyond traditional coding into 3D scene generation, Blender modeling, embodied simulation, frontend development, presentation design, video creation, and music composition. MiMo-V2.6-Pro can take text, images, video, and other visual inputs and coordinate multi-agent workflows to produce and iteratively refine complex outputs. Research applications demonstrated by Xiaomi include materials discovery, literature analysis, computational simulation, hypothesis generation, and formalizing mathematical proofs in Lean. Xiaomi has released the model alongside its technical report, reinforcement learning environments, and RL code so researchers can study and reproduce the training approach. MiMo-V2.6-Pro is also available in an UltraSpeed configuration that provides substantially faster output for latency-sensitive workflows. Users can access the model through MiMo Desktop, AI Studio, MiMo Code, the MiMo API Platform, OpenRouter, and Hugging Face.
