Notes on the record
Launched 2026-11-09 (Meta AI Research blog dated November 9, 2026; @AIatMeta post 2026-11-09T18:04:15Z and the pricing thread). The Standard model id is `muse-ember-1.0`. Input is text, image, video, audio and PDF. Output is text. Meta lists a 1,048,576-token context, a 524,288-token maximum output, and reasoning effort from minimal to max with max as the default (dev.meta.ai/docs/muse-ember, checked 2026-11-10).
Pricing is tiered by request length. Up to 200K input tokens the rate is $0.10 input, $0.004 cached and $0.50 output per million tokens. Above 200K it is $0.30, $0.012 and $1.50, and the whole request is billed at that long-context tier (dev.meta.ai/docs/pricing-rate-limits, checked 2026-11-10). The stored headline is the $0.10/$0.50 short-context rate. The long-context tier is higher, so it is not stored as price_alt.
Meta publishes no Muse Ember parameter count or knowledge cutoff, and the docs link no weights, so those fields stay empty and the license is proprietary. No tracked independent Muse Ember score was on a board this site tracks at the 2026-11-10 scan, so this page adds no score row. Meta's launch table reports Agents' Last Exam at 61.6% as an internal Linux subset, not the tracked overall. Terminal-Bench 4.0 at 40.9% is that table's best-published-harness figure, and the Muse Ember harness named there is mini-swe-agent. OSWorld 2.1 on the same Muse Ember table is an internal 69.5% partial and 33.8% binary. None of those Muse Ember figures is a score row. The family is Muse Ember, so Muse Wonder is not marked a previous version.

FAQ
What does Muse Ember cost?
$0.10 in / $0.004 cached / $0.50 out per million tokens up to 200K input tokens. Above 200K the rate is $0.30 / $0.012 / $1.50, and the whole request is billed at that long-context tier (Meta pricing docs, checked 2026-11-10). The stored headline is the short-context rate, because the long-context rate is higher and cannot be price_alt.
What inputs does Muse Ember accept?
Text, image, video, audio and PDF input with text output under the Standard id `muse-ember-1.0`, a 1,048,576-token context and a 524,288-token maximum output (Meta docs, checked 2026-11-10).
What reasoning effort does Muse Ember offer?
Meta offers reasoning effort from minimal to max, with max as the default, according to the Muse Ember model docs checked 2026-11-10. The page does not publish a parameter count or a knowledge cutoff.
Is Muse Ember open source?
No. Meta's Muse Ember documentation links no weights, and this page records the license as proprietary. The docs also publish no parameter count or knowledge cutoff, so those remain empty rather than estimated.
Does Muse Ember replace Muse Wonder?
No. Muse Ember has its own family, Muse Ember, so it neither replaces Muse Wonder nor makes it a previous version. The two are separate product lines with different pricing: Muse Wonder is a flat $4/$20, while Muse Ember starts at $0.10/$0.50.
Has Muse Ember been independently benchmarked?
No tracked independent board had a Muse Ember row at the 2026-11-10 scan, so this page carries no score. Meta's launch-table cells for Agents' Last Exam, Terminal-Bench 4.0 and OSWorld 2.1 are claims in the notes above, not score rows.
