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.
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.

| Best for | analysis, coding, research, long agents | the hardest problems, longer thinking | frontier work at half the price |
| Price per 1M in / out | $10 / $50 | $10 / $50 | $5 / $30 |
| Context window | 1.05M tokens | 1.05M tokens | 1M tokens |
| Max output | 128k tokens | 128k tokens | 128k tokens |
| Input | text, images, PDFs | text, images, PDFs | text, images |
| On avots.ai | pay per use | pay per use | pay per use |
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.
