Imajev-4B
Photos checked against your record, with a trained “can’t tell”.
Two open image decision models · updated October 26, 2026
Both read a photo, take your typed questions and return a probability for every option instead of prose. Each is ahead on a different leaderboard: Imajev-4B is far ahead of Jev-Omni on Image JevBench, and Jev-Omni ranks far higher on the text JevBench. Here is why, and which one fits your decisions.
Jev-Omni is hosted in our Playground in beta. Imajev-4B is not offered on this site, and neither model is available through our public API.

One classifier for text, images, audio and video.

Jev-Omni has been offline since 19 October 2026, so this editor runs Jev 1.14, the model we recommend today. It also reads images.

Measured by the same third party
Benchmark Heaven runs both boards. On images, Imajev-4B is near the top of the open-weights systems and well clear of Jev-Omni on both accuracy axes, while Jev-Omni still answers faster. On text, Jev-Omni ranks 81 places higher, #52 against #133 on the open-weights board, and scores 21 points higher on intelligence.

Version 0.3.0 is a fresh start, not an update: a new pool of 2,441 items on 2,160 images, drawn as 300 public and 1,200 sealed decisions, of which 713 items are real and 1,728 synthetic. 67 systems were measured and 64 ranked; two more keep a separately dated v0.1.5 score and are not ranked on the v0.3 scale, and one is an unranked second read of H2O-Lightning-4B v1.4.1 under changed serving settings. No v0.3.0 score can be compared with a v0.1.5 one, and the per-system public and sealed item counts the old release published are not part of this one. Wity-1, the closed API that led v0.1.5, was re-measured on the new pool on 7 October at 71.2, and on 16 October Sqwish’s closed kettei-fat API entered above it at 75.4. With those two ahead, Imajev-4B then held the highest place of any system whose weights you can download. The same day kettei-chub, Sage 1.4 with images and Celeris-1 Decision joined too, all hosted APIs, and on 17 October the open-weights basal-omni-1.0-ultra, a text model reading images zero-shot, entered at #11, followed by Drex Max on 21 October at #8. On 27 October H2O.ai’s open-weights H2O-Lightning-4B v1.4.1 (image) entered at #3, above Imajev-4B. Together these additions pushed Jev-Omni down to #16. A 15 October addendum added TypeSafe’s two Jev-with-images preview rows, removed one row at its operator’s request and moved the board’s Jev-class cost reference to Jev with images, which widened the pool behind its Capability ranking and moved the Capability places above. No composite changed.
Read the test, not just the number
ImajevBench is the Imajev author’s benchmark: 279 test questions about photos, records and text, 21 of which have no answer the evidence supports. It is a preview with AI-generated images and no human audit yet.
Imajev-4B against Jev-Omni, run by the Imajev author with Jev-Omni’s own predict(). The author’s significance test, run on an earlier Imajev release, found a gap of this size not significant.
The gap comes from the “can’t tell” questions, which Jev-Omni has no output for. On answerable questions the author found Jev-Omni slightly ahead of an earlier Imajev release, and better calibrated.
Both return decision probabilities instead of generated explanations. Their inputs, limits and serving paths are not the same.
| Capability | Imajev-4B | Jev-Omni |
|---|---|---|
| Backbone | Qwen3.5-4B with a LoRA adapter and decision readout; also 2B and 9B | Gemma 4 12B IT, fine-tuned and merged |
| Images | Up to two per request, such as a reference and a target | One per request |
| Audio and video | Not supported | Video as 16 sampled frames; the model also takes audio, switched off on Jev AI after our tests |
| Can’t tell | A trained unknown probability and an abstained flag on every answer | No abstain output |
| Request format | TypeSafe-style /v1/systemone, plus images | Its own Python loader and predict(); hosted here in the Playground |
| Options | 2 to 254 per question, 1 to 8 questions per request | Head accepts 256; best supported at 20 or fewer |

Imajev-4B, and by a wider margin than before. On Image JevBench v0.3.0 it is fourth of 64 at 63.7, behind only kettei-fat at 75.4, Wity-1 at 71.2 and H2O-Lightning-4B v1.4.1 (image) at 66.6, against Jev-Omni’s 32.8 at #16, with intelligence 49.9 against 37.5 and calibration 86.1 against 71.0. On that board’s Capability ranking it is seventh at 68.0, with Jev-Omni #25 at 54.3. Jev-Omni answers faster. On the Imajev author’s own ImajevBench, Imajev-4B scores 83.9% against 78.5%.
Jev-Omni, by a wide margin. On the text JevBench v1.7.48 it is #52 of 235 open-weights systems at 71, with intelligence 55.5, and #52 on the headline Capability ranking; Imajev-4B is #133 at 30, with intelligence 34.6 and #103 on Capability.
Imajev-4B can: every answer carries a trained unknown probability and an abstained flag. Jev-Omni has no abstain output, so on questions whose honest answer is “can’t tell” it always picks one of the options.
Jev-Omni is hosted in this site’s Playground: sign in and run text, image or video decisions; audio runs on Clef-Omni. Imajev-4B has a demo on Hugging Face Spaces run by its author, and it also runs locally on Apple silicon.
No. Imajev is a third-party project by Mohit Garg and Jev-Omni a third-party model by akhilaaa3. Both borrow Jev’s typed-decision idea; TypeSafe’s Jev itself reads text only.
