ModelRunnerSettings

CORE · interface · 类型合同

Named settings keep all model limits together; output token reservation stays per call.

导入

TypeScript

import type { ModelRunnerSettings } from '@jangts/agent-core/model';

JavaScript

/** @typedef {import('@jangts/agent-core/model').ModelRunnerSettings} ModelRunnerSettings */

其他公开入口：@jangts/agent-core、@jangts/agent-core/model、@jangts/agent-core/types、@jangts/agent-core/structs。

定义

interface ModelRunnerSettings

继承或实现： Partial<ModelRuntimeConfig>。

字段结构

字段	类型	必需	说明
children	ModelChildPolicy | undefined	可省略	只读。见类型定义及调用场景。
maxInputChars	number | undefined	可省略	Character budget for the assembled input.
maxSchemaChars	number | undefined	可省略	Character allowance for registered capability schemas.
tokenBudget	ModelTokenBudget | undefined	可省略	见类型定义及调用场景。
maxOutputTokens	number | undefined	可省略	Default output reservation; invoke can override it for one call.
maxCalls	number | undefined	可省略	Calls allowed for the whole request, including descendant runners' reservations.
callTimeoutMs	number | undefined	可省略	Deadline for one provider call, in milliseconds.
maxOutputChars	number | undefined	可省略	Cap on streamed output characters; exceeding it fails the call.
usage	boolean | undefined	可省略	Request and record provider usage for each call.

使用示例

• ModelRunner：输入可以省写，输出合同保持一致：用真实 Provider 端口执行一次模型交互，返回 value 和本次 invocation。

同一输出的两种输入

入门 · Node.js

TypeScript

import { ModelRunner } from '@jangts/agent-core/model';
const provider = {
  async *stream(messages: readonly { content: string }[]) {
    yield '收到：' + messages.at(-1)!.content;
  },
};
const runner = new ModelRunner({ provider });
const first = await runner.invoke('你好');
const second = await runner.invoke({ input: '你好' });
console.log(first.value, second.value);
console.log(first.invocation.invocationId);

JavaScript

import { ModelRunner } from '@jangts/agent-core/model';
const provider = {
    async *stream(messages) {
        yield '收到：' + messages.at(-1).content;
    },
};
const runner = new ModelRunner({ provider });
const first = await runner.invoke('你好');
const second = await runner.invoke({ input: '你好' });
console.log(first.value, second.value);
console.log(first.invocation.invocationId);

配置 · Node.js

const provider = {
  async *stream(messages: readonly { content: string }[]) {
    yield '收到：' + messages.at(-1)!.content;
  },
};
const runner = new ModelRunner({ provider, maxCalls: 2, maxInputChars: 4000,
  maxOutputChars: 2000, callTimeoutMs: 15000,
  execution: { signal: AbortSignal.timeout(20000) },
});
const result = await runner.invoke({ input: '你好', stageId: 'reply', maxOutputTokens: 600 });
console.log(result.value, runner.remainingCalls);

JavaScript
