Claude Haiku 5.5 in plain words

Claude Haiku 5.5 is a text model from Anthropic. It takes text, images, and files as input and returns text. Its context window is 1,000,000 tokens. It costs 0.097 credits per 1M input tokens and 0.485 credits per 1M output tokens. A request with 100,000 or more input tokens is charged, as a whole, at 0.485 credits per 1M input tokens and 2.425 credits per 1M output tokens.

It is good at reasoning through multi-step problems, reading attached files, and calling tools. It reads images as well as text. It is one of the fast models in the catalog. A context window of 1,000,000 tokens holds about 4,000,000 characters of English text, at 4 characters a token.

For example, a question of 2,000 tokens (about 8,000 characters) with an answer of 1,000 tokens (about 4,000 characters) costs 0.000679 credits. The exact charge follows the usage the model reports for your request.
