Use Cases
- Agent prototyping: Build an agent by chatting with AI then refine logic with low code steps and controlled prompt versions
- Prompt iteration: Compare LLM outputs side by side and select prompts that improve accuracy and reduce unwanted variation
- Regression testing: Run evaluations on a saved dataset before release to catch quality drops after model or prompt changes
- RAG apps: Attach a knowledge base and test retrieval behavior with representative questions and strict document scope rules
- Stakeholder demos: Publish hosted agent apps so product and compliance reviewers can test behavior without local setup steps
- Model selection: Evaluate providers and self hosted options with the same tasks to choose the best cost and latency mix for production
- Speed up SDK usage for AWS services with correct patterns
- Generate tests and boilerplate from natural language comments
- Detect hardcoded secrets before code leaves your laptop
- Enable juniors to learn API usage by example in IDE
- Reduce copy paste from docs while keeping human review
