Pricing details for additional usage tiers are available on their official pricing page. - **Requirements:** Ensure TypeScript is supported in your project environment since Helicone's API is compatible with TypeScript.; Before integrating Helicone, verify that intelligent routing and fallback mechanisms align with the requirements of your LLM deployment scenario. - **Adopt for:** Helicone is an open-source LLM observability platform that supports monitoring, evaluation, and experimentation of Large Language Models using a simple integration. It provides advanced tracing, intelligent routing, cost ## Choose when ### Choose opik if… - opik is primarily Python; helicone is TypeScript. - Helicone and Opik both offer AI observability, evaluation, and optimization services. - Tags unique to opik: langchain, llm-observability, llama-index, llm-evaluation. - Use Opik when you are working on complex LLM systems or agentic workflows that require detailed observability and evaluation. ### Choose helicone if… - helicone is primarily TypeScript; opik is Python. - Pricing: Helicone offers a free tier (generous monthly 10k requests/month). Pricing details for additional usage tiers are available on their official pricing page.. - Requirements: Ensure TypeScript is supported in your project environment since Helicone's API is compatible with TypeScript.; Before integrating Helicone, verify that intelligent routing and fallback mechanisms align with the requirements of your LLM deployment scenario.. - Helicone and Opik both offer AI observability, evaluation, and optimization services. - Tags unique to helicone: agent-monitoring, cost-tracking, observability, model-routing. - Also covers Inference & Serving. - helicone ships Docker support for self-hosted deployment. - When you need to integrate multiple AI models with one API key through the OpenAI API, including automatic fallbacks. ## When NOT to use opik - Avoid using Opik if you only need basic tools for AI model monitoring without requiring advanced functionalities such as deep tracing or automatic optimization. - Do not use Opik if your project does not align with the observability and evaluation focus of this platform, preferring a more specialized tool. ## When NOT to use helicone - When the requirement demands strict adherence to proprietary systems, as Helicone encourages open-source development. - For projects that do not necessitate monitoring metrics such as cost and latency tracking via an external platform. - If your application does not need intelligent routing across multiple AI models or fallback mechanisms. ## Common questions ### What is the difference between opik and helicone? opik: Open-source AI Observability, Evaluation, and Optimization. helicone: Ice-cold observability for LLMs..
