Questions people ask
Is grok-4.3 better than glm-5.2?
glm-5.2 outperforms grok-4.3 on 6 of 7 shared benchmarks. See the benchmark comparison above for specifics: grok-4.3 and glm-5.2 have different strengths across reasoning, coding, math and multimodal tasks.
Which is cheaper, grok-4.3 or glm-5.2?
grok-4.3 is cheaper. grok-4.3 costs $1.25/$2.50 per 1M input/output tokens, while glm-5.2 costs $1.40/$4.40.
Can I use grok-4.3 and glm-5.2 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch between "xai/grok-4.3" and "zai/glm-5.2", no other code changes needed.
What are the context windows?
grok-4.3 supports up to 1M tokens of context. glm-5.2 supports up to 1M tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
Switch between grok-4.3 and glm-5.2 with one line of code
Requesty provides a single OpenAI-compatible API for 400+ models. Change the model parameter, not your code.
