llm-exe features

  • Full TypeScript support. Infers types throughout LLM chains, eliminating any/unknown values.
  • Provider agnostic. Same code works with OpenAI, Anthropic, Google, xAI, Ollama, AWS Bedrock, DeepSeek and more.
  • Composable executors. Chain modular executors (prompt + LLM + parser) and swap parts independently.
  • Powerful parsers. Parse JSON, lists, regex, markdown etc. with schema validation that throws on mismatch.
  • Built-in production features. Automatic retries, timeouts, error handling and hooks for logging/monitoring.
  • Function-calling agents. Turn any function into an LLM-callable tool, even for models without native function calling.
