OpenAI's flagship GPT‑6 Astra model is now available on OpenRouter, priced at $10 per million input tokens for demanding end‑to‑end tasks.
OpenAI’s flagship GPT‑6 Astra model has been added to the OpenRouter marketplace, widening the channel through which developers can tap the system’s “end‑to‑end” capabilities. The listing on OpenRouter details a 1.05 million‑token context window, a maximum output length of 128 000 tokens and a two‑provider architecture that promises higher uptime. Pricing is set at $10 per million input tokens and $50 per million output tokens, with rate limits that scale with a user’s spend tier.
The move matters because it extends Astra beyond OpenAI’s own ChatGPT Work, Codex and API tiers, which we covered on 5 September when the model was first rolled out to Plus, Pro, Enterprise and Business customers. By exposing Astra on an independent aggregator, OpenAI can reach a broader developer base that already uses OpenRouter to compare and switch between large‑language‑model providers. The model’s benchmark scores, supplied by Artificial Analysis, place it on par with leading competitors such as Claude Opus 5 and Fable 5, signalling that the performance edge that justified the premium pricing is now more widely testable.
OpenAI’s safety overview flags Astra as a “significant step up in cyber capabilities,” capable of autonomously discovering previously unknown security flaws. The company says it has “significantly strengthened” safeguards to prevent misuse, a point that dovetails with earlier concerns about the model’s opacity and alignment that we reported earlier this month.
What to watch next: how OpenRouter’s usage monitoring and rate‑limit policies interact with OpenAI’s internal safety controls, whether pricing or token limits are adjusted as demand grows, and if third‑party developers begin to surface novel use cases—or new security challenges—leveraging Astra’s expanded accessibility.
