GPT-6 Astra is a multimodal language model developed by OpenAI. It's particularly well-suited for analyzing images, screenshots, and visual content, tackling complex, multi-step reasoning problems, orchestrating tool-using agents that call APIs and external services, grounding responses in real-time web search results, producing structured outputs for reliable data extraction and handling large contexts of up to 1.1M tokens. Its 1.1M-token context window means you can pass in entire documents, codebases, or conversation histories without losing context. It can write up to 128K tokens in a single response.
As of Oct 28, 2026, GPT-6 Astra costs $3.73 per 1M input tokens and $18.67 per 1M output tokens on Qubax, versus $5.00 / $25.00 on OpenRouter (25% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $16.81. Measured availability over the last 7 days: 100.0%. 61 independent compute providers currently serve it, so requests fail over automatically. It handled 17,807 requests on Qubax in the last 24 hours.
