Question 1

What does this Grok Build 0.1 vs GLM-5.2 comparison cover?

Accepted Answer

It brings together documented inputs and outputs, token limits, deployment terms and available pricing. When both models have source-linked, verified results on a shared benchmark, those results are shown with their individual sources. The comparison is a starting point for evaluating your own workload.

Question 2

Which is cheaper: Grok Build 0.1 or GLM-5.2?

Accepted Answer

Grok Build 0.1 lists $1.00 input and $2.00 output per 1M tokens. GLM-5.2 lists $1.40 input and $4.40 output. The cheaper workload depends on the mix of input and output. Long-context tiers, caching, batch processing and retries can change the bill.

Question 3

Which has the larger context window: Grok Build 0.1 or GLM-5.2?

Accepted Answer

Grok Build 0.1 lists 256K tokens and GLM-5.2 lists 1M. GLM-5.2 therefore has the larger recorded context window, but capacity alone is not a quality score.

Question 4

Which is faster: Grok Build 0.1 or GLM-5.2?

Accepted Answer

There is no matched speed measurement for both models with the same source, host, region and date. Test the same prompts at your expected concurrency and measure time to the first useful response as well as complete task time.

Question 5

What input and output types do Grok Build 0.1 and GLM-5.2 support?

Accepted Answer

Grok Build 0.1 records text, image, pdf input and text output. GLM-5.2 records text input and text output. “Not documented” means the current source record is incomplete; it does not prove that a modality is unsupported.

Question 6

Should I choose Grok Build 0.1 or GLM-5.2?

Accepted Answer

Consider Grok Build 0.1 if you need larger maximum output or a lower listed input rate or a lower listed output rate. Consider GLM-5.2 if you need larger context. GLM-5.2 offers downloadable weights; Grok Build 0.1 is listed as a proprietary model. Compare licence terms and operating costs before choosing a deployment. Test both on the same representative examples and judge the output against your acceptance criteria. Include tool failures, retries and the time to a completed task.
