doubleword/glm-5.2

this id pins the doubleword deployment, with no routing and no failover. the managed id on the canonical page routes across all 11 providers instead

main.py
from openai import OpenAI client = OpenAI(    api_key="YOUR_REQUESTY_API_KEY",    base_url="https://router.requesty.ai/v1",) response = client.chat.completions.create(    model="doubleword/glm-5.2",    messages=[        {"role": "user", "content": "Explain quantum computing in one paragraph."},    ],) print(response.choices[0].message.content)

Change the base url to https://router.requesty.ai/v1, use your Requesty key, set the model to the id above. Existing OpenAI SDK code needs no other edit, and the same key reaches every other model in the catalog. Browse all models

notes

reference

Z.ai's next-generation flagship model for agentic software engineering, with significantly stronger coding capabilities than GLM-5.1.

questions 6

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 1.0M tokens, with a maximum output of 131K tokens per response. That is roughly 1,398 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, 68.8% on Coding Index. The benchmarks pane shows every published result, each normalised to 100.
What can glm-5.2 do?
glm-5.2 supports 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 "doubleword/glm-5.2". The quickstart pane 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 Doubleword. You do not host the model yourself: point base_url at Requesty, set the model to "doubleword/glm-5.2", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
