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

Yes. GLM-4-Plus 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-plus . Keep your current request and response handling.

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

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

How does GLM-4-Plus score on benchmarks?

Recorded results for GLM-4-Plus: arena_text 66.1. Benchmark positions are a coarse filter only — run your own prompts against the candidate models before you commit, because ranking shifts with task shape and prompt style.

How should you set the output budget for GLM-4-Plus?

Set max_tokens on GLM-4-Plus to the longest response your task actually needs, not the 4,095-token ceiling. Keeping the cap tight reduces worst-case spend and shortens tail latency. Raise it only for tasks that demonstrably need longer output.

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

GLM-4-Plus 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 check before using it?

128,000 context, 4,095 output tokens

GLM model that supports tool calling. Released 2024-08.

Why use it through MixRoute?

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

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

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Tool calling

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

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

Streaming

GLM-4-Plus supports streamed responses.

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

Prompt caching

GLM-4-Plus 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-Plus through MixRoute's OpenAI-compatible endpoint.

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