Are any of these open source?
GLM-4.6V-Flash and Qwen3 VL 235B A22B Instruct publishes its weights and can be self-hosted; Grok Code Fast 1 is proprietary.
Which is newer?
GLM-4.6V-Flash is the newest, released Dec 8, 2025. Qwen3 VL 235B A22B Instruct came out Sep 23, 2025; Grok Code Fast 1 came out Sep 2, 2025. Knowledge cutoff: Qwen3 VL 235B A22B Instruct Mar 31, 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.
