Mercury 2.5 diffusion LLM launches at 80% off, p99 voice latency cut from minutes to 1s

Inception Labs' Mercury 2.5 diffusion LLM is now available via its API, OpenRouter, and Baseten, with 100M free tokens for new accounts. Launch pricing is 80% off at $0.04/M input and $0.15/M output tokens. OpenCall AI uses Mercury for voice agents on live patient calls: after switching from an AI inference chip provider, p50 latency fell below 200ms and p99 dropped from several minutes to one second, fitting multi-step reasoning inside a live call's latency budget.
