Evals & Testing
Unit testing for AI. Ensures that changes to your prompts don't break the model's accuracy.
| Rank | Model | Price | Summary |
|---|---|---|---|
|
1
|
Open Source | The CI/CD Standard. It treats prompts like code, integrating directly into GitHub Actions to block PRs if they degrade model performance. Its matrix view allows you to test 50 prompts against 10 models simultaneously. | |
|
2
|
Open Source | The RAG Specialist. The industry standard for 'Reference-Free' evaluation. It uses judge models to mathematically score your retrieval pipeline on Faithfulness, Context Relevancy, and Answer Correctness without needing human ground truth. | |
|
3
|
Open Source | The Unit Test Framework. Designed to look and feel exactly like Pytest. It allows developers to write 'assert_faithfulness' checks in their existing test suites, bringing LLM testing into the standard TDD loop. | |
|
4
|
Open Source | The Security Scanner. While others test for accuracy, Giskard scans for vulnerabilities. It automatically generates thousands of adversarial attacks (injections, hallucinations, bias) to find holes in your logic before deployment. | |
|
5
|
Open Source | The Developer's Choice. A lightweight, fast evaluation platform that focuses on 'Tracing as Testing'. It allows you to click on any step in a production trace and instantly turn it into a regression test case. |
