# Best Coding agents — Open models

> Source: https://theagentsindex.com/best/coding-agents/open-models (curated, quality-gated, re-verified)

16 of 28 coding agents have a confirmed yes for “Open models”. 7 are qualified or tier-scoped, 5 are confirmed no, and 0 remain not established. Only confirmed yes answers appear in this set; an unknown is never treated as a negative.

This is not an arbitrary slice of coding agents. Among the ones with a confirmed yes for “Open models”, 15 of 16 also answer yes on bring your own key, against 4 of 12 across the rest of the category. Every figure is counted from the stored, sourced datasheet answers linked on each row.

All four support open-weight models (Llama, DeepSeek, Mixtral-class and similar), but only through a bring-your-own-provider setup; none of these bundle a hosted open model for you, so the real differentiator is how much setup each one demands before you can point it at a local or self-hosted model.

## Methodology

Projected from the live listing datasheets using the tenant’s “Can it run open-weight models?” axis. Membership requires a sourced yes; partial and unknown answers are reported above but excluded from the ranking. Differences from the rest of the category are Fisher exact tests over 34 other datasheet axes, Holm-corrected. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
