What changed
Meta describes Ember as a model for tool calls, code subtasks, routing and long-document parsing. It accepts text, images, audio and video and produces text. Its reported benchmark results are vendor-presented and are not an independent ranking by this site.
Who it's for
Teams orchestrating many small agent steps may want to compare it with their existing fast models. Creators and analysts can also evaluate its handling of mixed media and documents, subject to access and practical testing.
How to try it
Meta lists muse-ember-1.0 on the Meta Model API and Muse Code. Check current access, usage limits and API documentation for your account.
What it costs
Meta Model API: $0.1 input / $0.5 output per 1M text tokens. Standard text rate; long-context tiers may differ.
Cached input and long-context tiers are priced differently. Check the current rate card before estimating a workload.
