DiffusionGemma 26B A4B IT accepts text and images; Nemotron 3.5 Lightning 30B A3B accepts text; Hy-MT2-1.8B accepts text. DiffusionGemma 26B A4B IT handles the widest range of inputs.
Are any of these open source?
Yes, all three publish their weights (Apache 2.0), so you can self-host them.
Which is newer?
Nemotron 3.5 Lightning 30B A3B is the newest, released Aug 11, 2026. DiffusionGemma 26B A4B IT came out Jun 9, 2026; Hy-MT2-1.8B came out May 21, 2026. Knowledge cutoff: DiffusionGemma 26B A4B IT Jan 2025, Nemotron 3.5 Lightning 30B A3B Sep 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
