Meta API Pricing, Models & Rate Limits (2026)
Meta serves its proprietary Muse Spark family through a first-party, OpenAI-compatible Model API — a break from the open-weight Llama models it previously shipped for third-party hosts like Groq. It offers two pricing tiers on the same model: a private Standard tier, and a Contributor tier priced up to 95% lower in exchange for Meta training on your inputs and outputs.
Also known as: Muse, Meta AI.
How much does the Meta API cost?
Meta API pricing is usage-based and varies by model and token volume. Use the current model table and provider documentation to estimate a workload before committing to production.
For cross-provider quota units and fixed-workload capacity, see the LLM API rate-limit comparison; this page remains the authoritative owner for Meta provider facts.
Meta product vs API
