Helicone Ship your AI app with confidence

What is Helicone?

Helicone is a comprehensive platform designed to support the entire lifecycle of Large Language Model (LLM) applications. It offers a suite of tools to help developers monitor, debug, and enhance their AI-powered applications, ensuring optimal performance and reliability.

From initial development to deployment and beyond, Helicone provides the necessary infrastructure to log request data, evaluate performance, conduct experiments, and deploy with confidence. It integrates seamlessly with popular models and offers both proxy and asynchronous integration options for maximum flexibility.

Features

Logging: Visualize multi-step LLM interactions, log requests in real-time and pinpoint root cause of errors.
Evaluation: Monitor performance in real-time and catch regressions pre-deployment with LLM-as-a-judge or custom evals.
Experiments: Tune prompts and justify iterations with quantifiable data.
Deployment: Unified insights across all providers to quickly detect hallucinations, abuse and performance issues.
Prompt Playground: Test and refine prompts before deployment.
Caching: Use caching for faster response.
API Key Management: Manage API Key usage and restriction.

Use Cases

Debugging LLM applications
Monitoring LLM application performance
Improving prompt quality
Preventing regressions in LLM applications
Evaluating LLM applications using various methods
Experimenting with different prompts and models

FAQs

Is there an impact to the latency of the calls to LLM?

There are two ways to interface with Helicone - Proxy and Async. You can integrate with Helicone using the async integration to ensure zero propagation delay, or choose proxy for the simplest integration and access to gateway features like caching, rate limiting, API key management.
I don't want to use Helicone's Proxy, can I still use Helicone?

Yes, you can use Helicone without using the proxy.
How do you calculate the cost of LLM requests?

The content doesn't explicitly state how the cost calculation works, but implies it does track the costs.
Which Helicone plan is right for me?

It depends on the project and team, you can start with Hobby plan. For teams the Pro plan offers more features and for growing companies Team plan is the best value.
What are the limits for each plan?

Hobby plan allows 10,000 free requests. Pro and Team plan has no usage limits. See pricing page for more.
