About

GPT-6 Astra is OpenAI’s frontier AI model for computer use, software engineering, scientific research, cybersecurity, browsing, and complex professional work. It combines advanced reasoning with agentic capabilities that allow it to navigate software, use tools, conduct research, manipulate data, troubleshoot systems, and complete multistep workflows. Astra is also designed to produce polished documents, spreadsheets, presentations, websites, applications, and other business or technical artifacts while following existing templates and organizational standards. In Codex, the model introduces improved long-running context management that can preserve notes and retrieve information from earlier context windows during extended software engineering tasks. OpenAI positions Astra as its most aligned model to date, with improvements in respecting task boundaries, interpreting user intent, communicating limitations, and avoiding unauthorized actions.

About

Step 5 Preview is StepFun’s flagship model for agentic work, designed for real-world tasks across software engineering and professional knowledge work, with particular strength in finance. It natively supports text, image, and video input and provides a 1M-token context window, enabling tasks that require large amounts of information, tool calls, and continuous progress toward a deliverable. The model can analyze long documents, multiple source materials, and conversation history for cross-document question answering and research organization. For programming and software engineering, it works across multiple languages and can support troubleshooting, code changes, verification, and test creation. Its multi-step agent capabilities let applications provide tools for retrieving information, processing documents, conducting deep research, and producing analytical reports. Multimodal understanding combines images, video, and text for chart analysis, screenshot question answering, etc.

Pros & Cons from Real Users

Pros

  • For coding, it is especially strong. I can hand it a bigger problem, ask it to reason through the architecture, generate code, catch issues, and refine the solution without needing to restart the whole conversation every few minutes. The computer-use and browsing improvements are also noticeable. Astra feels less like a chatbot and more like an agent that can actually move through a workflow, gather context, and turn it into something useful. What I like most is that it is not just smarter in a trivia sense. It is better at doing work: planning, debugging, researching, writing, analyzing, and pulling complicated pieces together.

Cons

  • Only downside so far really is cost. It's expensive.
