ProviderReasoningLevel

SUPPORT · type · Type contract

Supplier wire shape is explicit; levels express requested effort, not measured quality.

Import

TypeScript

import type { ProviderReasoningLevel } from '@jangts/agent-core/support';

Examples

• Reasoning strategies: explicit wire format and natural levels: Support generates reasoning parameters from an explicitly chosen protocol format, preserving exact overrides and custom mappings.

Generate a thinking budget for an explicit wire format

Configuration · Node.js

This only assembles configuration and sends no network request. At call time the output token limit must be larger than the thinking budget.

TypeScript

import { Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
  baseUrl: 'https://provider.example', apiKey: 'placeholder', model: 'configured-model',
  reasoning: { format: 'thinking-budget', level: 'high', budgets: { high: 6000 } },
} });
console.log(provider instanceof Support.CompatibleModelProvider);

JavaScript

import { Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
        baseUrl: 'https://provider.example', apiKey: 'placeholder', model: 'configured-model',
        reasoning: { format: 'thinking-budget', level: 'high', budgets: { high: 6000 } },
    } });
console.log(provider instanceof Support.CompatibleModelProvider);

Map a custom provider while keeping exact overrides of original fields

Extension · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
  baseUrl: 'https://provider.example', apiKey: 'placeholder', model: 'configured-model',
  reasoning: { format: 'custom', level: 'medium', map(level) { return { analysis_mode: level }; } },
  requestBody: { analysis_mode: 'app-defined' },
} });
console.log(provider instanceof Support.CompatibleModelProvider);

JavaScript

import { Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
        baseUrl: 'https://provider.example', apiKey: 'placeholder', model: 'configured-model',
        reasoning: { format: 'custom', level: 'medium', map(level) { return { analysis_mode: level }; } },
        requestBody: { analysis_mode: 'app-defined' },
    } });
console.log(provider instanceof Support.CompatibleModelProvider);
