Frequently asked questions

How much does glm-5.2 cost?
glm-5.2 is priced at $1.40 per million input tokens and $4.40 per million output tokens when accessed via Requesty. Requesty charges exactly what the upstream provider charges, we don't add markup.
What is the context window of glm-5.2?
glm-5.2 has a context window of 1M tokens, with a maximum output of 131K tokens per response. That's roughly 1,333 words of input you can fit in a single prompt.
How does glm-5.2 perform on benchmarks?
glm-5.2 scores 99.1% on τ²-Bench, 89.5% on GPQA Diamond, 50.8% on Terminal-Bench Hard. See the full benchmark chart above for results across MMLU Pro, GPQA Diamond, SWE-Bench Verified, HumanEval, MATH, AIME, MMMU, and LiveBench.
What can glm-5.2 do?
glm-5.2 supports tool calling, extended reasoning. You can call it through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use glm-5.2 with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "nebius/glm-5.2". The Quickstart above shows Python, JavaScript and cURL snippets.
Can I run glm-5.2 through Requesty?
Yes. glm-5.2 runs through Requesty's OpenAI-compatible API, served from Nebius AI. You do not host the model yourself: point base_url at Requesty, set the model to "nebius/glm-5.2", and requests are routed to the upstream provider with automatic failover. The same key gives you 400+ other models too.
