Too close to call
It is close. Our weighted score puts them within a point (GLM-5-Turbo 38/100, GLM-5 37/100), so choose by what matters most for your work: GLM-5 on price and GLM-5 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: GLM-5 or GLM-5-Turbo?
It is close. Our weighted score puts them within a point (GLM-5-Turbo 38/100, GLM-5 37/100), so choose by what matters most for your work: GLM-5 on price and GLM-5 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, GLM-5 or GLM-5-Turbo?
GLM-5 is cheaper at $1.00 input / $3.20 output per million tokens (official Z.AI API price). GLM-5-Turbo costs $1.20 input / $4.00 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $1.55 per million tokens for GLM-5 versus $1.90 for GLM-5-Turbo (1.2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. GLM-5 has an ECI of 145.8 and GLM-5-Turbo has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for GLM-5-Turbo 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?
GLM-5 has the largest context window at 204,800 tokens, against 200,000 for GLM-5-Turbo. Maximum output per response: GLM-5 up to 131,072, GLM-5-Turbo up to 131,072 tokens.
Which can read images, PDFs, audio or video?
GLM-5 accepts text; GLM-5-Turbo accepts text. They handle the same number of input types.
Are any of these open source?
GLM-5 publishes its weights and can be self-hosted; GLM-5-Turbo is proprietary.
Which is newer?
GLM-5-Turbo is the newest, released Mar 16, 2026. GLM-5 came out Feb 12, 2026.
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.
