Frequently Asked Questions

  • How does Mercury Coder Small Beta's diffusion approach differ from standard code models?

    It generates a full draft, then refines all token positions in parallel over iterative passes. Standard code models generate tokens left to right, one at a time. This parallel approach enables higher throughput on the same hardware.

  • What is Mercury Coder Small Beta's fill-in-the-middle score?

    84.8 on FIM benchmarks. FIM measures how well a model generates code that fits between an existing prefix and suffix, which maps to editor autocomplete.

  • How does Mercury Coder Small Beta perform on HumanEval?

    90.0 on HumanEval in Inception's published Mercury Coder tables.

  • What throughput does Mercury Coder Small Beta achieve?

    Live throughput metrics appear on this page.

  • Is Mercury Coder Small Beta suitable for multi-language coding tasks?

    Yes. Its MultiPL-E score is 76.2 across multiple programming languages beyond Python, with Python-centric benchmarks showing its strongest results.

  • How does Mercury Coder Small Beta relate to Mercury 2?

    Mercury Coder Small Beta is a smaller, coding-focused model from an earlier generation of the Mercury diffusion family. Mercury 2 is a later, broader reasoning model with a larger context window and tunable reasoning depth.

  • Where are the benchmark numbers published?

    Inception published HumanEval, FIM, MBPP, and MultiPL-E figures for Mercury Coder in its Mercury announcement. See https://platform.inceptionlabs.ai.

  • What does Mercury Coder Small Beta cost?
