Overview
Meta's first proprietary, paid-API model and the flagship of the new Meta Model API — a multimodal agentic model with a 1M-token context that takes text, image, video, audio and PDF input. Built for tool calling, computer use and coding. $1.25/$4.25 per 1M tokens, with cached input at $0.15. Unlike Llama, it is API-only: there are no open weights.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 50.6 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 37.5 (Tool use, planning, autonomy)
- AA-Omniscience Index: 18 (−100–100)
- GDPval-AA v2: 1375.1 ELO (Real-world work tasks, human baseline = 1000)
- LMSYS Chatbot Arena: 1489.7 ELO (Human preference)
- Ranks #25 of 136 comparably-measured models by percentile score, across 5 independent measurements
- Ranks #55 of 136 comparably-tested models by normalized performance per dollar
