Do you need downloadable weights?
Use the weight field to separate API-only models from downloadable options. Read the stated use restriction before deploying an open-weight model.

Catalog current through July 21, 2026
Five source-backed models whose Epoch records explicitly include code generation. This is a shortlist, not a performance ranking.
Selection rule
Included when the Epoch record explicitly lists “Code generation.” Release date, lab, access, and weight availability do not improve a model’s position because this page has no positions.
Task-fit shortlist
Ordered by release date for readability, newest first. The order is not a score or recommendation.

Decision criteria
These checks narrow an evaluation plan. They do not replace hands-on testing.
Use the weight field to separate API-only models from downloadable options. Read the stated use restriction before deploying an open-weight model.
Domain labels can identify models with vision or multimodal coverage. They do not prove performance on screenshots, diagrams, or interface work.
Run representative repository tasks for correctness, tool use, latency, context handling, and cost. Epoch's catalog does not report those fields.
Evidence boundary
No task-level quality, price, context window, latency, or reliability measurement is present in the Epoch catalog. We therefore publish no ranking or “best” label.
