What Helicone is
Helicone is an AI gateway and LLM observability product for AI teams and engineers building AI applications. It supports routing, debugging and analysis across AI model providers. It offers a seven-day free trial without requiring a credit card.
Users access models through the OpenAI SDK and can switch providers by changing the model name. Helicone routes requests through one interface, selecting models by cost, speed, accuracy or availability. It also provides load balancing, failovers and response caching. The product logs requests in real time, visualises multi-step LLM interactions, and provides cross-provider insights into hallucinations, abuse, errors and performance issues.
