Helicone: LLM Gateway, Logging and Usage Pricing
What does Helicone do?
Helicone documents an OpenAI-compatible gateway for routing requests to multiple model providers, with logging and observability. Its platform also includes cost tracking, sessions and evaluation-related features. A gateway can centralize a request path, but the application still needs explicit behavior when a provider fails or returns an unusable answer.
Who should consider it?
Teams maintaining several model integrations may want one place to inspect usage and routing. Before adding another service to the request path, identify the problem it should solve: cost attribution, provider switching or debugging. If existing provider logs already answer that question, a gateway adds operational work without an obvious benefit.
How does pricing work?
Hobby is listed as free with 10,000 requests, 1 GB storage and one seat. Pro is $79 per month with usage-based pricing still applying. The pricing table separates request allowances, storage and retention. Model inference is another cost dimension; compare the full bill rather than treating the observability subscription as an all-inclusive model plan.
How should you test a gateway change?
Use synthetic prompts and a narrow staging workload. Record the intended model, response schema and timeout behavior. Exercise both an ordinary response and a simulated provider failure. Verify which provider actually served the fallback and whether the returned answer still meets the application contract.
What should pass before production?
A useful checklist includes correct request attribution, no secrets in stored logs, consistent response parsing and a documented fallback policy. Compare measured application latency with and without the extra request path. Ensure cost reports distinguish original calls from retries and do not count a cached response as fresh inference.
What data and lifecycle questions matter?
Request logs can contain user input and proprietary context. Confirm retention and deletion requirements before enabling full-body logging. Review current provider-routing and account terms because operational ownership and service offerings can change. Preserve a tested direct-provider fallback path if gateway availability is critical to your application.
Which alternatives fit?
Compare Langfuse and LangSmith for tracing-oriented workflows, and Braintrust for evaluation workflows. They overlap in observability but should not be assumed to offer identical routing or retention behavior.
