Class: QueryGenerator

Defined in: packages/agentos/src/query-router/QueryGenerator.ts:136

Builds tier-appropriate prompts and generates LLM answers.

The generator selects a model (standard vs. deep) based on the query tier, constructs a system prompt with optional documentation context and research synthesis, then delegates to generateText for the actual LLM call.

Example​

const gen = new QueryGenerator({
  model: 'openai:gpt-4.1-mini',
  modelDeep: 'openai:gpt-4.1',
  provider: 'openai',
});

const result = await gen.generate('How does auth work?', 1, chunks);
console.log(result.answer);
