What is the max output length for GLM-4-AIR?

GLM-4-AIR returns up to 4,095 output tokens per request, within a 128,000-token context window. Cap the response with the max_tokens parameter so a single call cannot run past your budget.

What should you evaluate before moving production traffic to GLM-4-AIR?

Before switching production traffic to GLM-4-AIR, run a pilot on a representative slice of your traffic and check output quality, latency at peak concurrency, and cost per request. Verify the error and retry behaviour, and confirm the request limits you depend on match your plan.

Can you call GLM-4-AIR with the OpenAI SDK you already use?

Yes. GLM-4-AIR 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-air . Keep your current request and response handling.

When was GLM-4-AIR released, and is it still maintained?

GLM-4-AIR was released on 2024-06-05. Its catalog status is stable. Check the model page for deprecation notices before you build a long-lived integration on it.

What is the rate limit for GLM-4-AIR?

The current model record does not publish a numeric rate limit for GLM-4-AIR. 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.

What should you check before using it?

128,000 context, 4,095 output tokens

GLM model that supports tool calling and structured output. Released 2024-06-05.

Why use it through MixRoute?

Swap the base URL, keep the GLM-4-AIR client

MixRoute serves GLM-4-AIR on the OpenAI-compatible endpoint /v1/chat/completions; point your existing client at https://api.mixroute.ai/v1 with the model ID glm-4-air and re-run your integration tests.

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Tool calling

GLM-4-AIR 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-AIR can produce JSON-formatted output on demand.

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

Streaming

GLM-4-AIR supports streamed responses.

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

OpenAI SDK

Call GLM-4-AIR 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-AIR is billed per use and the record publishes no free-tier allowance. The current published rates are input $0.071429 per 1M tokens and output $0.071429 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.
