04 — Questions

Which should you choose?

Which is better: Grok 4.3 or GLM-5-Turbo?

Grok 4.3 is the better all-round choice, scoring 56/100 against GLM-5-Turbo (38). It leads on price, inputs & features and context window. 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, Grok 4.3 or GLM-5-Turbo?

Grok 4.3 is cheaper at $1.25 input / $2.50 output per million tokens (official xAI 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 $1.56 per million tokens for Grok 4.3 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. Grok 4.3 has an ECI of 149.2 and GLM-5-Turbo has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Grok 4.3 and 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?

Grok 4.3 has the largest context window at 1,000,000 tokens, against 200,000 for GLM-5-Turbo. Maximum output per response: Grok 4.3 up to 30,000, GLM-5-Turbo up to 131,072 tokens.

Which can read images, PDFs, audio or video?

Grok 4.3 accepts text, images and PDFs; GLM-5-Turbo accepts text. Grok 4.3 handles the widest range of inputs.

Are any of these open source?

Which is newer?

Grok 4.3 is the newest, released Apr 17, 2026. GLM-5-Turbo came out Mar 16, 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.
