## Providers

- **openai** — ctx 1050000, input $10.00/M, output $50.00/M

## Verdict

GPT-6 Astra delivers OpenAI's largest context window yet at 1.05M tokens, making it the go-to for processing entire codebases, legal document sets, or multi-hour meeting transcripts in a single pass. The trade-off is steep pricing at $50/Mtok output — roughly 2.5× Claude Sonnet 4 — which limits its use to scenarios where context length genuinely matters more than cost. Reach for this when you need to reason over massive documents and can justify the premium for not chunking or retrieval-augmenting your workflow.
