Latest update (11-09 14:56): Meta's Muse Ember now available on OpenRouter

Overview: Meta's Muse Ember is now available on OpenRouter and in OpenCode, according to OpenRouter and OpenCode posts and an account of Alexandr Wang. OpenRouter lists text, images, video and audio as inputs and suggests pairing Muse Ember with a frontier model such as Muse Wonder, which handles planning while Muse Ember runs bounded sub-tasks in coding agents.

Design Arena ranks Muse Ember 10th overall on its Overall HTML leaderboard with an Elo of 1345, according to its post. The post says Muse Ember averages 33 seconds per generation, 9.5 times faster than the previous frontier models it replaced, and costs $0.10 per 1M input tokens and $0.50 per 1M output tokens, at least 34 times cheaper on average. The OpenRouter reports do not give context length or other performance figures.
