Mercury 3 is a diffusion-based language model from Inception, and the lab's most capable model to date. It is suited for agentic workflows and real-time applications where latency compounds, such as search agents, voice pipelines, and coding subagents. Its distinguishing trait is speed: more than 40x larger than the first Mercury model while generating at the same throughput, because it produces and refines tokens in parallel rather than one at a time.

Throughput is how fast the model writes (tokens per second, higher is better). Time to first token is how long before the answer starts (lower is better).
Share of requests served without a server error. Client errors (4xx) do not count.

On NagaAI, Mercury 3 costs $0.05 per 1M input tokens and $0.175 per 1M output tokens. You pay only for what you use, with no subscription.
Mercury 3 reads up to 1M tokens in one request, counting the prompt and the answer together.
Yes. Mercury 3 can call your functions as tools and can answer in a JSON schema you give it.
It takes text as input and returns text.
