GLM 4.7 Flash serves the OpenAI-compatible Chat Completions API. Point any OpenAI SDK at https://api.empiriolabs.ai/v1 with your EmpirioLabs API key and use the model id glm-4-7-flash. Get an API key from the EmpirioLabs dashboard.

print(response.choices[0].message.content)Request parameters supported by the GLM 4.7 Flash API on EmpirioLabs. Defaults apply when a field is omitted.
| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| temperature | number | 1 | 0 to 1 | Sampling temperature. Lower values are more deterministic. GLM-4.7-Flash and GLM-4.6V-Flash default to 1.0; GLM-4.5-Flash defaults to 0.6. |
| top_p | number | 0.95 | 0.01 to 1 | Nucleus sampling probability mass. Z.AI documents a 0.95 default for the GLM-4.7, GLM-4.6, and GLM-4.5 series. |
| max_tokens | number | 4096 | 1 to 131072 | Maximum output tokens for GLM-4.7-Flash: 131072. |
| stop | array | - | - | Stop word list. Z.AI currently supports one stop string in array form. |
| do_sample | boolean | true | - | Enable sampling. When false, temperature and top_p do not affect generation. |
| enable_thinking | boolean | true | - | Controls Z.AI thinking mode. Enabled is the default and makes GLM-4.7-Flash think; disable it for simple low-latency turns. |
| thinking | object | - | - | Advanced thinking object. Use {"type":"enabled"} or {"type":"disabled"}. GLM-4.7-Flash thinks when enabled. |
| response_format | object | - | - | Set {"type":"json_object"} for JSON mode or {"type":"text"} for plain text. |
| tools | array | - | - | Function tools and the built-in web_search tool are supported. |
| tool_choice | enum | auto | auto | Controls whether the model may use tools. Z.AI documents auto tool selection; omit tools to disable tool use. |
| tool_stream | boolean | false | - | Stream function-call tool output when stream is true. Z.AI documents tool_stream for GLM-4.6 and newer models. |
| tool_web_search | boolean | false | - | Enable built-in web search. Adds $0.033 per request when enabled. |
| search_result | boolean | true | - | Return structured web search result metadata when web search is enabled. |
| search_prompt | string | - | - | Optional instruction for summarizing retrieved web search results. |
Base token use is free. Built-in web search is optional through tool_web_search and adds $0.033 per request when enabled.
On EmpirioLabs, GLM 4.7 Flash is billed pay as you go: Input Free per 1M prompt tokens; Output Free per 1M generated tokens; Implicit cache read Free per 1M cached input tokens. The live rate card on this page always matches what the API charges.
GLM 4.7 Flash supports a 200K-token context window with up to 131,072 output tokens per response.
Yes. GLM 4.7 Flash serves the OpenAI-compatible Chat Completions API, so existing OpenAI SDKs work by pointing base_url at https://api.empiriolabs.ai/v1 and setting the model id to glm-4-7-flash.
Yes. The EmpirioLabs playground runs GLM 4.7 Flash in the browser with the same parameters the API exposes, so you can test prompts before writing code.
