OpenAI: GPT-6 Astra
Analysis Summary
OpenAI's GPT-6 Astra combines a 52.7 intelligence index with a 76.9 coding index and a 51 agentic index. It supports text, image, and file input, tool use, and function calling, with a 1.05M-token context window. This puts it in the high-capability tier for reasoning and software work, with the long context and multimodal input supporting complex tasks beyond short prompts.
For an agency, Astra is a strong candidate for coding assistance, tool-using agents, and analysis across large document sets. Its vision and file input also support workflows that mix text with visual material. The main trade-off is cost: listed rates are $10 per million input tokens and $50 per million output tokens. Use it where depth and reliability matter, and route routine, high-volume work to a less expensive model.
