How to read this profile

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.

We track Mercury Edit 2, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.

Mercury Edit 2 is a proprietary model with a 128K context window. No explicit reasoning mode is documented in this profile.

A diffusion next-edit-prediction model served through the Inception API (the blog index dates the launch to March 30, 2026; the post itself carries a September 9, 2026 update stamp). Inception does not publish a context window for the edit model; the value is inherited from the Mercury 2 family.

Inception reports Mercury Edit 2 as superior on Instinct, fill-in-the-middle, next-edit-prediction, and an internal next-edit benchmark, with a 48% higher acceptance rate and 27% more selective suggestions than its predecessor, but publishes no exact scores, so BenchLM stores no scored rows. The row stays unranked.

The profile has no source-displayable benchmark row yet.

Frequently asked questions

How does Mercury Edit 2 perform overall in AI benchmarks?

Mercury Edit 2 does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.

Does Mercury Edit 2 have full benchmark coverage on BenchLM?

No. Mercury Edit 2 currently has 0 source-displayable rows across 434 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.

What is the context window size of Mercury Edit 2?

Mercury Edit 2 has a documented context window of 128K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
