- Collaborative Debugging: Trace multi-step agent workflows end-to-end to pinpoint failures in RAG pipelines or tool integrations.
- Compliance-Critical Deployments: Securely manage healthcare/financial LLM apps with audit trails via self-hosted instances.
Key Features of Helicone
- One-Line Integration: Compatible with JavaScript/Python SDKs and frameworks like LangChain/LlamaIndex without disrupting existing workflows.
- Response Caching & Retry Logic: Reduces API costs by 40-60% through smart caching while automatically handling rate limits across providers.
- Prompt Experimentation Suite: Test variations directly on production traffic via UI to refine outputs without code changes.
- Granular User Management: Track usage patterns by custom tags (user/session IDs) and enforce rate limits per API key or endpoint.
Final Recommendation for Helicone
- Essential for DevOps Teams: Prioritizes actionable metrics over raw data visualization for engineers scaling LLM apps beyond prototypes.
- Ideal for Cost-Conscious Startups: Free tier (1M monthly requests) supports early-stage validation while Pro plan unlocks caching/retries at $25/month.
- Recommended for Regulated Industries: On-prem deployment capabilities make it uniquely suited for healthcare/fintech applications requiring data isolation.
Frequently Asked Questions about Helicone
What is Helicone?▾
Helicone is an observability layer for AI/LLM usage that helps teams track requests, responses, and performance metrics to understand model behavior and costs.
How do I get started with Helicone?▾
Sign up on the website, install the recommended SDK or instrument your API client to send telemetry, and then view calls and metrics in the Helicone dashboard; consult the quickstart docs for step‑by‑step instructions.
Which model providers and deployments does Helicone work with?▾
Helicone is designed to work with common LLM providers and self‑hosted deployments via API instrumentation, so you can typically monitor requests to providers like OpenAI, Azure OpenAI, Anthropic, or your own model endpoints—check the docs for exact integration guides.
How does Helicone address privacy and security?▾
Observability platforms like Helicone typically transmit telemetry over encrypted channels and offer configuration to avoid logging sensitive fields; review Helicone's data retention, access control, and encryption documentation for specifics and compliance options.
Will Helicone add noticeable latency to my API calls?▾
Most monitoring setups add minimal overhead because telemetry can be batched or sent asynchronously, but exact impact depends on your integration method (client SDK vs. proxy); measure latency in a staging environment before deploying to production.
What are the pricing options for Helicone?▾
Pricing commonly includes a free or trial tier plus usage‑based and enterprise plans; visit Helicone's pricing page or contact sales for current tiers, quotas, and enterprise terms.
Can I query and analyze logged requests and metrics?▾
Yes—Helicone provides querying, aggregation, and dashboarding capabilities so you can filter, group, and visualize request/response patterns, performance metrics, and cost-related data.
How long does Helicone retain telemetry data and can I change it?▾
Retention periods vary by plan and are often configurable; check the account settings or documentation for retention policies and options to adjust or archive data.
How can I export or delete my data from Helicone?▾
Most platforms provide export (CSV/JSON or API) and deletion tools or retention policies to remove data; consult Helicone's data management documentation or support for the exact export and deletion procedures.
What should I do if I don't see logs or metrics in the dashboard?▾
Verify your SDK or instrumentation is using the correct API key/endpoint, check network connectivity and sampling settings, and review any error logs; if issues persist, contact Helicone support with request IDs and timestamps for troubleshooting.
