Usage

export interface Env {
  AI: Ai;
}

export default {
  async fetch(request, env): Promise<Response> {

    const messages = [
      { role: "system", content: "You are a friendly assistant" },

        content: "What is the origin of the phrase Hello, World",
      },
    ];

    const stream = await env.AI.run("@cf/zai-org/glm-4.7-flash", {

Parameters

Input

prompt

stringrequiredminLength: 1The input text prompt for the model to generate a response.

model

stringID of the model to use (e.g. '@cf/zai-org/glm-4.7-flash, etc').

▶audio{}

objectParameters for audio output. Required when modalities includes 'audio'.

frequency_penalty

number | nullPenalizes new tokens based on their existing frequency in the text so far.

logit_bias

object | nullModify the likelihood of specified tokens appearing in the completion. Maps token IDs to bias values from -100 to 100.

logprobs

boolean | nullWhether to return log probabilities of the output tokens.

top_logprobs

integer | nullHow many top log probabilities to return at each token position (0-20). Requires logprobs=true.

max_tokens

integer | nullDeprecated in favor of max_completion_tokens. The maximum number of tokens to generate.

max_completion_tokens

integer | nullAn upper bound for the number of tokens that can be generated for a completion.

metadata

object | nullSet of 16 key-value pairs that can be attached to the object.

modalities

array | nullOutput types requested from the model (e.g. ['text'] or ['text', 'audio']).

n

integer | nullHow many chat completion choices to generate for each input message.

parallel_tool_calls

booleandefault: trueWhether to enable parallel function calling during tool use.

▶prediction{}

object

presence_penalty

number | nullPenalizes new tokens based on whether they appear in the text so far.

▶chat_template_kwargs{}

object

▶response_format

one ofSpecifies the format the model must output.

seed

integer | nullIf specified, the system will make a best effort to sample deterministically.

▶stop

one of

store

boolean | nullWhether to store the output for model distillation / evals.

stream

boolean | nullIf true, partial message deltas will be sent as server-sent events.

▶stream_options{}

object

temperature

number | nullSampling temperature between 0 and 2.

▶tool_choice

one ofControls which (if any) tool is called by the model. 'none' = no tools, 'auto' = model decides, 'required' = must call a tool.

▶tools[]

arrayA list of tools the model may call.

top_p

number | nullNucleus sampling: considers the results of the tokens with top_p probability mass.

user

stringA unique identifier representing your end-user, for abuse monitoring.

▶web_search_options{}

objectOptions for the web search tool (when using built-in web search).

▶function_call

one of
