openai/gpt-6-astra is listed at $10/$50 per million tokens with a 1,050,000-token context window, tiered above 272K tokens. Specs, pricing, and what is unverified. Esta guía está escrita para equipos de producto y plataforma que comparan calidad de modelos, costo, política de enrutado y riesgo de despliegue.
What shipped
GPT-6 Astra is listed in the NextModel catalog as openai/gpt-6-astra: a 1,050,000-token context window, chat and Responses API support, and Thinking, Streaming, Computer Use, and Function Calling capabilities, with a maximum output of 8,192 tokens per request. OpenAI announced the model on September 3, 2026, positioning it as a frontier agent model; its announcement cites a 72.6% OSWorld computer-use score and near-perfect retrieval on long-context needle benchmarks. Call it through the same OpenAI-compatible base URL you already use for the rest of the catalog.
Pricing
Listed at $10 input and $50 output per million tokens (USD) for prompts up to 272,000 tokens, with cache hits at $1. Above 272,000 tokens the listed tier is $20/$75 with $2 cache hits. See the worked examples in our pricing explainer before sending half-million-token prompts.
Who this launch is for
The catalog tags vision, long-context, and agent use cases. Concretely: whole-repository reasoning, million-token document analysis, agent runs where the model operates a computer, and retrieval-heavy workloads where you would rather pay for context than maintain a RAG pipeline.
What is unverified
Benchmark figures quoted here are OpenAI's own published numbers, not first-party measurements. The catalog lists no latency band for this model yet, and there is no first-party CacheSafety row for gpt-6-astra in the NextModel bench table. Benchmark against your own workload before routing production traffic.
FAQ
What model id do I send for GPT-6 Astra?
Send openai/gpt-6-astra to your NextModel base URL with the OpenAI SDK you already have. Both the Chat Completions and Responses APIs are supported.
Is GPT-6 Astra billed differently above 272K tokens?
Yes. The catalog lists $10/$50 per million tokens up to 272,000 prompt tokens, and $20/$75 above that, with cache hits at $1 and $2 respectively. Price your prompt size before you paste a whole repository in.
Do I need a new integration?
No. NextModel exposes one OpenAI-compatible endpoint, so switching to Astra is a one-string model id change in your existing code.
