Too close to call
It is close. Our weighted score puts them within 2 points (GLM-4.6V 59/100, Seed 2.0 Code 57/100, Qwen3 Coder Next 51/100), so choose by what matters most for your work: Qwen3 Coder Next on price. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which can read images, PDFs, audio or video?
Qwen3 Coder Next accepts text; Seed 2.0 Code accepts text, images and video; GLM-4.6V accepts text, images and video. Seed 2.0 Code handles the widest range of inputs.
Are any of these open source?
Qwen3 Coder Next and GLM-4.6V publishes its weights and can be self-hosted; Seed 2.0 Code is proprietary.
Which is newer?
Seed 2.0 Code is the newest, released Feb 14, 2026. Qwen3 Coder Next came out Feb 3, 2026; GLM-4.6V came out Dec 8, 2025. Knowledge cutoff: Qwen3 Coder Next Sep 2025, GLM-4.6V Apr 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 Oct 4, 2026.
