MUSE EMBER API PRICING
What Meta charges for Muse Ember, in USD, cross-checked daily against the public pricing dataset. Effective price — if there's a promo running, this is the promo.
Meta publishes no separate marginal rate above the line — just this one number, same shape as the whole-request pricing Google, Anthropic and xAI confirm. The scenarios below stay under the line; a large-codebase agent run often doesn't.
USAGE: <0.2% of OpenRouter tokens in the week of 2026-11-02. What people actually run. Source: OpenRouter (openrouter.ai/rankings), as of 2026-11-12.
NOTE: Same list price as Claude Haiku 5.5 and GPT-6 Luna, but cache reads cost $0.004/MTok (0.04x input). Past 200K prompt tokens the whole request reprices to $0.30/$1.50. No contributor discount.
WHAT THINGS ACTUALLY COST ON MUSE EMBER
| Scenario | Tokens in / out | 1 run | 1,000 runs |
|---|---|---|---|
| A typical prompt (300 tokens in) | 300 / ~900 | $0.0005 | $0.48 |
| A 20-turn conversation (context re-sent) | 4,000 / ~4,000 | $0.0024 | $2.40 |
| Summarizing a 10-page document | 8,000 / ~3,200 | $0.0024 | $2.40 |
| One agent run (tools, retries, thinking) | 2,000 / ~12,000 | $0.0062 | $6.20 |
| A code review request | 1,500 / ~3,750 | $0.0020 | $2.02 |
Output sizes assume the same editorial ratios as the Burn Calculator (3x for prompts, 6x for agent runs). Estimates, not invoices.
VS. THE REST OF THE BOARD
“Same job” = a 1,000-token prompt with a 3,000-token reply, priced on both models. Cheaper is not always better. It is, however, always cheaper.
PRICE HISTORY
Muse Ember joins the board at $0.10 in / $0.50 out per MTok, the same list price as Claude Haiku 5.5. Cached reads are where it pulls ahead: $0.004 against Haiku's $0.01.
