1M token context
About a million tokens in one conversation, enough for a large repository or a stack of long documents.
Anthropic released Claude Opus 5.5 on September 22, 2026, as the successor to Claude Opus 5: the same 1 million token context window, text, images and files as input, and a lower price of 4 USD in and 20 USD out per million tokens. On avots.ai you run it pay per use, with no Claude Pro or Max plan, and the same balance covers GPT-6, Gemini, Grok and 40+ image, video and music models.
