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), so choose by what matters most for your work: GLM-4.6V on price and Seed 2.0 Code for long inputs. 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 should you choose?
Which is better: Seed 2.0 Code or GLM-4.6V?
It is close. Our weighted score puts them within 2 points (GLM-4.6V 59/100, Seed 2.0 Code 57/100), so choose by what matters most for your work: GLM-4.6V on price and Seed 2.0 Code for long inputs. 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 is cheaper, Seed 2.0 Code or GLM-4.6V?
GLM-4.6V is cheaper at $0.30 input / $0.90 output per million tokens (official Z.AI API price). Seed 2.0 Code costs $0.475 input / $2.37 output per million tokens (official Volcengine Ark API price). At a typical mix of three input tokens to one output token, that is $0.45 per million tokens for GLM-4.6V versus $0.95 for Seed 2.0 Code (2.1× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Seed 2.0 Code has not been scored yet and GLM-4.6V has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Seed 2.0 Code and GLM-4.6V yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.
Which has the bigger context window?
Seed 2.0 Code has the largest context window at 262,144 tokens, against 128,000 for GLM-4.6V. Maximum output per response: Seed 2.0 Code up to 131,072, GLM-4.6V up to 32,768 tokens.
Which can read images, PDFs, audio or video?
Seed 2.0 Code accepts text, images and video; GLM-4.6V accepts text, images and video. They handle the same number of input types.
Are any of these open source?
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. GLM-4.6V came out Dec 8, 2025. Knowledge cutoff: 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.
