Alternatives to Qwen-2.5-1B-RLCD
Grouped by the reason you would actually switch, not by a leaderboard position that does not exist yet.
Qwen-2.5-1B-RLCD is open weights already, so switching is about fit rather than about control.
The reasons to move are narrow: a licence you can ship, a size you can afford, a format you can deploy, or an architecture whose confidence you trust. Each group below is one of those reasons.
1 of the 134 projects in our directory reference Qwen-2.5-1B-RLCD, so there is working code to read before you commit either way. Full detail on the model itself is on its page.
Licensed for commercial use
Apache-2.0 or MIT. Start here if this is going into a product, because licence rules a model out faster than any benchmark.
laya
The most-liked open-weight decision model of the post-Jev wave, a 421M ModernBERT-large encoder. The base release of a three-model family.
cua-s1-forms
A System One model narrowed to one job, filling forms. MIT licensed, and the clearest example in the directory of the interface spreading past the benchmark it was born on.
laya-multilingual
The only multilingual decision model we have found, a 322M encoder on mmBERT. Also the one our English-only test set cannot say anything useful about.
decider-2b
The most-downloaded open-weight decision model in the post-Jev wave. A Qwen3.5-2B decoder fine-tuned to emit typed decisions, and the largest member of a three-model family.
laya-typed-decisions
The Laya variant tuned on the typed-decisions benchmark, and the only open model whose card publishes head-to-head numbers against Jev. One of those numbers is the reason we started measuring.
open-jev-deberta-v3-large
A DeBERTa-v3-large encoder positioned as an open reimplementation of Jev. The highest ratio of likes to downloads in the directory, which is usually what a credible claim looks like early.
Same architecture family
Closest in how the probability is actually produced, which matters more than size if you intend to route on confidence.
decider-2b
The most-downloaded open-weight decision model in the post-Jev wave. A Qwen3.5-2B decoder fine-tuned to emit typed decisions, and the largest member of a three-model family.
LFM2.5-350M-RLCD
A typed-decision model from notnotsamuel, 354M parameters. Licensed other, check before commercial use.
JEV-CPU
Qwen3-0.6B fine-tuned to return typed decisions.
laya-vision-smolvlm-256m
SmolVLM-256M-Instruct fine-tuned to return typed decisions, 237M parameters. Licensed cc-by-nc-sa-4.0, check before commercial use.
decider-2b-vision
Qwen3.5-2B-Base fine-tuned to return typed decisions, 2.2B parameters.
LFM2.5-2.6B-RLCD
LFM2.5-2.6B fine-tuned to return typed decisions, 2.7B parameters. Licensed other, check before commercial use.
Smaller and cheaper to run
Fewer parameters, so cheaper per decision at volume. Whether they give up accuracy for it is unmeasured.

The honest caveat
None of these has been benchmarked against Qwen-2.5-1B-RLCD by anyone independent, including us. This page groups candidates by facts you can check. It cannot tell you which one holds up on your traffic, and anyone presenting a ranking here is guessing.
