What is the rate limit for GLM-4.5-X?

The current model record does not publish a numeric rate limit for GLM-4.5-X. Confirm the quota for your plan in the console, then run a short load test at your expected concurrency to establish the effective ceiling before production.

Can you call GLM-4.5-X with the OpenAI SDK you already use?

Yes. GLM-4.5-X is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to glm-4.5-x . Keep your current request and response handling.

How are reasoning tokens billed on GLM-4.5-X?

Reasoning tokens are billed as output on GLM-4.5-X, at $8.9 per 1,000,000 token. They are generated before the visible answer and count toward both latency and spend, so a higher reasoning setting costs more even when the final answer is short.

Can you control the reasoning budget on GLM-4.5-X?

GLM-4.5-X is a reasoning model. Reasoning effort can be tuned per request. Lower effort settings cut reasoning tokens and cost for routine work; reserve higher settings for problems that need deeper search. Measure quality at two or three settings before fixing one in production.

When was GLM-4.5-X released, and is it still maintained?

GLM-4.5-X was released on 2025-07-28. Its catalog status is stable. Check the model page for deprecation notices before you build a long-lived integration on it.

What should you check before using it?

128,000 context, 16,384 output tokens

GLM model that supports reasoning and tool calling. Released 2025-07-28.

Why use it through MixRoute?

GLM-4.5-X cache reads cut repeated-prompt cost

Cached prefixes are billed at 0.45 USD per 1M tokens instead of 2.2 USD, so repeated system prompts cost less. MixRoute serves GLM-4.5-X on the OpenAI-compatible endpoint /v1/chat/completions; point your existing client at https://api.mixroute.ai/v1 with the model ID glm-4.5-x and re-run your integration tests.

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Tool calling

GLM-4.5-X supports function and tool calls.

EX Send a tools definition; the response returns tool_calls to execute and feed results back.

Structured output

GLM-4.5-X can produce JSON-formatted output on demand.

EX response_format: { type: "json_schema" } forces valid JSON output.

Streaming

GLM-4.5-X supports streamed responses.

EX stream: true streams tokens incrementally, so chat UIs render as they arrive.

Prompt caching

GLM-4.5-X supports prompt caching under supported routing conditions.

EX Keep the system prompt and tool definitions at the start of the request; repeated prefixes are automatically billed at the cache-read rate.

OpenAI SDK

Call GLM-4.5-X through MixRoute's OpenAI-compatible endpoint.

EX Change base_url to https://api.mixroute.ai/v1; everything else follows the OpenAI style.

FAQ

GLM-4.5-X is billed per use and the record publishes no free-tier allowance. The current published rates are input $2.2000 per 1M tokens and output $8.9000 per 1M tokens. Trial credit or promotional quota is tied to your account rather than to the model, so check the console before planning around a free tier.
