VernLLM

What happens when your LLM call hits a rate limit, times out, or returns malformed JSON? With VernLLM, it just works. One typed call() wraps retries, timeouts, cancellation, and a self-healing circuit breaker, skipping retries on errors that won't fix themselves, like bad JSON or bad key. Get typed, Zod validated output via native JSON Schema mode. Cache calls, track cost per request, plug in your own logger. One interface across OpenAI, Groq, Anthropic, Gemini, Bedrock, and more.
