Meta AI has launched Muse Ember, a reasoning model for tasks including tool calls, coding subtasks, extraction and long-document parsing, Simon Willison reported. It supports up to a million input tokens and offers six reasoning levels.

For prompts of up to 200k tokens, input costs $0.10 per million tokens and output costs $0.50 per million. Above that threshold, the rates rise to $0.30 and $1.50 respectively. Willison cautioned that reasoning models can consume different numbers of tokens to solve the same problem, limiting comparisons based solely on token prices.
