Opik vs Paperspace Gradient

Opik helps teams building applications or agents that call an LLM log actions and evaluate behavior across development, testing, and production. It captures and visualizes traces, supports annotation, and provides audit logs. Its evaluation tools include more than 30 metrics for outcomes such as answer relevance, context precision, task completion, and hallucination. In production, Opik can evaluate traces in real time, alert when criteria fail, and track token use and model costs. Test Suites offer pass/fail assertions, an Agent Playground supports end-to-end tests, and a Prompt Optimizer provides six algorithms. Core observability and evaluation features are available as open-source code for local use. Opik includes a REST API and Python client, with Python and TypeScript SDKs listed, and integrations with more than 40 frameworks, model providers, and gateways. Free Cloud allows up to 10 team members, 25,000 spans per month, and 60-day retention. Pro Cloud costs $19 a month and lists up to 50 team members and 100,000 spans monthly.

Paperspace Gradient is a machine-learning platform for developing and operating models. It combines managed compute with experiment tracking, a model registry, pipeline orchestration, model serving and data versioning. Gradient is available on Linux, macOS, Windows and the web. Free plans for individual users and teams include 5 GB of storage; no hourly or maximum monthly price is shown for those plans. Paid plans are billed hourly up to a maximum monthly price. Pro — User costs $8 a month and includes 15 GB of storage, while Growth — User costs $39 a month with 50 GB. Team plans include Pro — Team at $12 a month with 15 GB of storage and Growth — Team at $39 a month with 50 GB. Those listed paid prices are maximum monthly prices, not a statement of a fixed hourly charge. The combination of compute and tools for tracking data, organizing pipelines and serving models covers several stages of machine-learning work.
