Frequently asked questions about Parea
What is Parea AI used for?
Parea AI is used for testing, evaluating, and monitoring LLM-powered applications throughout their development lifecycle. It helps AI engineering teams track experiments, collect human annotation feedback, debug failures, optimize prompts through a playground, and monitor production performance including cost, latency, and quality. The platform automates creation of domain-specific evaluations by turning human annotations into scalable evaluation functions.
How do I get started with Parea AI?
Create a Parea account at parea.ai using your email or social accounts like Google or Twitter. Then create an Organization by clicking your profile avatar and selecting 'Create Organization'. Go to the API Keys tab under Settings and click 'Create new API key' under the Parea API Key section. Anyone in your organization can use this key to authenticate requests. You should also set your organization's model provider keys to avoid providing LLM Model API keys through the API/SDK.
What integrations does Parea support?
Parea has native integrations with major LLM providers and frameworks including OpenAI SDK, Anthropic SDK, LangChain, Instructor, LiteLLM, DSPy, SGLang, Maven, and Trigger.dev. Both Python and TypeScript SDKs are available, with OpenAI, LangChain, and LiteLLM supporting both languages. Anthropic and Instructor work with Python only, while DSPy and SGLang are Python-only.
How does Parea's evaluation system work?
Parea automates evaluation creation by bootstrapping evaluation functions with human annotations. You can define evaluation functions locally in your codebase that receive a Log object and return a float or boolean value, or create evaluation functions on the platform. Evaluations run non-blocking in separate threads and results are logged. You can also run evaluations on a sample of logs by setting a sampling rate using apply_eval_frac (Python) or applyEvalFrac (TypeScript) to reduce evaluation costs.
What observability features does Parea provide?
Parea's observability features include input/output tracking, LLM performance monitoring, error monitoring that captures raised errors in your application, and performance tracking for token counts, cost, and latency per request. The dashboard provides aggregated metrics like requests over time, average latency, time to first token (TTFT), total cost, average tokens, and average user feedback/evaluation scores. You can drill down into trace details to view inputs, outputs, LLM messages, model parameters, and custom metadata.
What is included in Parea's Prompt Playground?
The Prompt Playground allows you to tinker with multiple prompts on samples, test them on large datasets, and deploy the best ones into production. It is version-controlled and enhanced for better prompt engineering. You can open specific spans from trace logs directly in the prompt playground to quickly iterate on failure cases and compare different prompt variations.
How does human annotation work in Parea?
Parea's Human Review feature lets you collect human feedback from end users, subject matter experts, and product teams. You can comment on, annotate, and label logs for Q&A and fine-tuning purposes. This human feedback is used to bootstrap automated evaluation functions, turning subjective assessments into scalable and reliable evaluations aligned with human judgment for quality assurance.
Can I use Parea for fine-tuning models?
Yes, Parea's Dataset feature allows you to incorporate logs from staging and production environments into test datasets that can be used for fine-tuning models. The platform helps you build test case datasets from trace logs, which can then be leveraged for model fine-tuning to improve performance.
What is the difference between Parea's free and paid plans?
The Free Builder plan includes all platform features but limits you to 2 team members, 3k logs/month with 1-month retention, and 10 deployed prompts. The Team plan at $150/month includes 3 members (expandable to 20 at $50/month each), 100k logs/month, 3-month retention (upgradable to 6/12 months), unlimited projects, 100 deployed prompts, and a private Slack channel. Enterprise offers custom pricing with unlimited logs, on-prem/self-hosting, SSO, custom roles, and enhanced security features.
Is Parea AI suitable for enterprise use?
Yes, Parea offers an Enterprise plan specifically designed for larger organizations. Enterprise features include on-prem/self-hosting options, support SLAs, unlimited logs, unlimited deployed prompts, SSO enforcement, custom roles, and additional security and compliance features. The platform is already trusted by teams at companies like SweepAI, CodeStory, SixFold AI, and Trellis Law, demonstrating its capability for production enterprise use.
