GPT-6 Astra online: OpenAI's new flagship, pay per use

OpenAI released GPT-6 Astra on September 3, 2026 and called it its most intelligent and aligned model. It is built for demanding end-to-end work: analysis, software engineering, deep research and long agent runs that drive a computer or a browser, with a 1 million token context. On avots.ai you use GPT-6 Astra and GPT-6 Astra Pro pay per use, no ChatGPT plan, and the same balance also covers Claude Fable 5.1, Gemini, Kimi K3 and 40+ image, video and music models.

Astra and Astra Pro are the same model: Pro runs with the reasoning mode set to pro, so it thinks longer and uses more tokens per answer at the same price per token. Keep GPT-5.6 Sol for volume work, switch to Astra when the task is worth it. One balance covers all three.

What is new

What GPT-6 Astra brings

A generational step

OpenAI's largest training run so far, on more than 100,000 GPUs, and near-perfect scores on core reasoning tests: 94.6% on GPQA Diamond, ahead of GPT-5.6 Sol and Claude Fable 5.

Built for long agent runs

Designed for work that spans hours and tools: computer and browser use, multi-step research, large refactors, full documents from a brief.

1M context, files in

About a million tokens of context and 128k output, with PDFs and images read directly. A whole codebase or a case file fits in one conversation.

Pro mode on demand

GPT-6 Astra Pro is the same model with deeper reasoning. Pick it per task in the model picker instead of paying for a separate plan.

FAQ

GPT-6 Astra questions

What is GPT-6 Astra?
GPT-6 Astra is OpenAI's flagship model released on September 3, 2026. OpenAI calls it its most intelligent and aligned model, built for demanding end-to-end work: advanced analysis, software engineering, deep research, scientific work and document creation, with particular strength in long agent runs that use a computer or browser. It reads about a million tokens of text, images and PDFs.
What is the difference between GPT-6 Astra and GPT-6 Astra Pro?
Same model, different reasoning mode. Astra Pro runs with reasoning set to pro, so it thinks longer and answers complex tasks with higher quality. It costs the same per token but uses more of them per answer. Pick Astra for everyday work and Astra Pro for the hardest problems.
How much does GPT-6 Astra cost on avots.ai?
Pay per use, no subscription. The model is priced at 10 USD per million input tokens and 50 USD per million output tokens, about twice GPT-5.6 Sol. On avots.ai you top up from 0.99 EUR and every reply shows its token cost before you run it, so a short question costs a handful of tokens.
Do I need ChatGPT Pro to use GPT-6?
No. avots.ai routes to GPT-6 Astra through the official API, so you use the same model without a ChatGPT plan. Pay only for the tokens you use, in the web app, Telegram, MCP or the OpenAI compatible API.
GPT-6 Astra or Claude Fable 5.1?
Both arrived in the first days of September 2026 at the same list price. Astra leads on reasoning benchmarks such as GPQA Diamond, Fable 5.1 is tuned for long agentic coding and knowledge work. On avots.ai they sit in one picker on one balance, so the honest answer is to run your own task on both and keep the winner.
