# Mercury 3 from @_inception_ai is live on AI Gateway at a 50% discount.

## Retrieval answer

**Thesis:** Gateway availability makes model choice easier to test, but does not establish task-level suitability.

**Thesis:** Gateway availability makes model choice easier to test, but does not establish task-level suitability.

Vercel says Mercury 3 from Inception is now available on AI Gateway under `inception/mercury-3`, and that it can also be set up for coding agents. **Mechanism:** A common Gateway API and documented coding-agent setup reduce the integration work required to trial a new model; diffusion-based parallel refinement is the model-generation approach described by Vercel. That lowers the integration step for teams already using Gateway; it does not remove the need to evaluate the model on their own prompts, tools, and latency constraints.

**Why now:** Vercel is advertising launch pricing at 50% off, and reports throughput claims that make the release timely for teams considering latency-sensitive trials. The company also cites a 1M-token context window and names browser agents, real-time search, interactive education, and customer support as latency-sensitive uses. **Evidence boundary:** The supplied public source is Vercel’s announcement. Performance, speed, and context claims are attributed to Vercel and are not independently verified here; no customer deployment results are provided.

**First implication:** Teams using AI Gateway can add Mercury 3 to comparative evaluations without adopting a separate model-calling surface. Whether its speed, context capacity, or output quality translates into better completed tasks remains an empirical question. **First watch condition:** Watch for independent or workload-specific measurements of end-to-end latency, output quality, and cost on real agent tasks, rather than relying on headline token speed alone.
