An evaluation row appears only where at least two of these models report the same benchmark with the same stated configuration, metric, unit and setup. Different evaluators stay named in each cell. Values are shown as reported: no unit conversion, no ranking.

Other Reported Results

These results are listed for each model on its own, because the conditions needed to compare them are not stated or do not match. Two results that leave a condition blank are not assumed to share it.

SAVRN's Notes on Qwen3.5-2B

2.3B parameters, image and text in, text out, over a 262,144-token context: 5.5 GB at 16-bit, 2.7 GB at 8-bit and 1.4 GB at 4-bit on the one 192 GB MI300X at $1.85 an hour that anchors our small-model pricing — the weights take a sliver and the long context fills the rest. This is the entry point of Qwen's natively multimodal 3.5 line, first published 2026-02-28 at 4.8M downloads a month.

Apache 2.0 covers commercial use, modification and redistribution. Reported scores — GPQA Diamond 44.9495, MMLU-Pro 55.3 — set honest expectations: this is the edge and appliance tier, and the derived list includes Rockchip RK182X LLM and VLM ports, which tells you where the community is taking it. For a bigger multimodal step, the 4B sibling doubles capacity for roughly twice the memory.

SAVRN's Notes on Rax-4.5

2.3B parameters carrying a 262,144-token context with image-plus-text input. At 16-bit the weights are 4.5 GB and the run needs 5.5 GB; 8-bit is 2.7 GB and 4-bit 1.4 GB — any of them fits the cheapest card in our table, one MI300X at $1.85 an hour, and the spare room matters because a filled 262K context adds memory on top of the weights. The pull is a single 4.5 GB safetensors shard.

Apache 2.0 covers commercial use. The open question is lineage: the architecture field reads Qwen3_5ForConditionalGeneration, but the only relation on record points back to Rax-4.5 itself, so the base model and training data are unstated — ask the publisher before you depend on it. RaxCore released it November 27, 2025 and updated it July 13, 2026; no SAVRN Index host prices it, and it draws 952.2k downloads a month.
