no long-context premium — the same rate across the full window. A `muse-spark-1.2-contributor` tier bills $0.10 in / $0.002 cached / $0.20 out in exchange for permission to use the prompts, code, files and context you send, plus the responses you get back, to train future Meta models, at 150 RPM against the standard tier's 3,000. Web-search grounding is $2.50 per 1,000 queries on top

the models page states 1,048,576; the board keeps its rounded 1M

Meta caches the stable prefix automatically — no flag or key

Watch out

Superseded by Muse Spark 1.3 at an identical rate; 1.1 and 1.2 are both still on the pricing page. Meta's first closed model — this row is not open weights, and nothing in the Llama licence applies to it

What we would use it for

Coding agents on a first-party Meta endpoint, flat-priced across 1M tokens

What this has cost, week by week

Output price at each refresh since 2026-08-14. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.

08-14 $4.25→08-20 $4.25→08-27 $4.25→09-03 $4.25→09-10 $4.25→09-17 $4.25→09-24 $4.25→10-01 $4.25→10-08 $4.25→10-15 $4.25→10-22 $4.25

Nothing has moved since we started tracking it.
