GPT-6 Astra is live

GPT-6 Astra is available on BetterToken as gpt-6-astra for complex reasoning, coding, research, computer use, and long-running agent workflows. In practice.

Updated: September 5, 2026

BetterToken now supports GPT-6 Astra with the exact Model ID gpt-6-astra. OpenAI describes Astra as its most capable model for difficult end-to-end work, including complex reasoning, software engineering, research, computer use, and document creation. Check current availability and BetterToken pricing in the model plaza.

Highlights

  • End-to-end work: designed for complex, multistep tasks across code, browsers, tools, and professional applications
  • Software engineering: OpenAI positions Astra as its strongest model so far for coding and agentic software development
  • Large context: OpenAI documents a 1,050,000-token context window and up to 128,000 output tokens
  • Adjustable reasoning: the OpenAI API supports low, medium, high, xhigh, and max reasoning effort
  • Responses API tools: OpenAI documents support for function calling, structured outputs, web search, file search, code interpreter, computer use, MCP, and other Responses API tools

Configuration recommendations

  • Use Astra for difficult coding, research, computer-use, or long-running agent tasks. For routine work, compare it with faster or lower-cost models in the model plaza.
  • Start with a representative test task before switching production traffic. Compare output quality, latency, and token usage in your own workflow.
  • Use https://bettertoken.ai for Claude Code and https://bettertoken.ai/v1 for Codex CLI and OpenAI-compatible tools. Choose the endpoint for the protocol your client uses. Model ID: gpt-6-astra.
  • Availability can change during a staged rollout. Treat the model plaza as the source of truth for BetterToken availability and pricing.
