01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Qwen3 Coder Flash 50/100, GLM-4.5V 49/100), so choose by what matters most for your work: Qwen3 Coder Flash on price and Qwen3 Coder Flash 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.

04 — Questions

Which should you choose?

Which is better: Qwen3 Coder Flash or GLM-4.5V?

It is close. Our weighted score puts them within a point (Qwen3 Coder Flash 50/100, GLM-4.5V 49/100), so choose by what matters most for your work: Qwen3 Coder Flash on price and Qwen3 Coder Flash 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, Qwen3 Coder Flash or GLM-4.5V?

Qwen3 Coder Flash is cheaper at $0.30 input / $1.50 output per million tokens (official Alibaba API price). GLM-4.5V costs $0.60 input / $1.80 output per million tokens (official Z.AI API price).

Which can read images, PDFs, audio or video?

Qwen3 Coder Flash accepts text; GLM-4.5V accepts text, images and video. GLM-4.5V handles the widest range of inputs.

Are any of these open source?

GLM-4.5V publishes its weights and can be self-hosted; Qwen3 Coder Flash is proprietary.

Which is newer?

GLM-4.5V is the newest, released Aug 11, 2025. Qwen3 Coder Flash came out Jul 28, 2025. Knowledge cutoff: Qwen3 Coder Flash Apr 2025, GLM-4.5V 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.
