Inception Labs · 2026-02-24
Mercury 2 is Inception Labs' diffusion-based reasoning language model, announced in February 2026 with tunable reasoning, native tool use, and structured JSON output. Unlike autoregressive models, it generates text through parallel refinement, producing multiple tokens simultaneously. Mercury 2 supports a 128K-token context window and is designed for high-throughput production reasoning workloads.
