- Traces appear almost instantly even at high volumes
- Flexible hosting options including self-hosted, cloud, and custom deployments
- Easy integration with just a few lines of code
- Opik automatically turns trace data and eval results into code fixes
| - Reaches answers across unrelated documents that share no keywords, where vector search scores zero
- Deterministic retrieval with no model in the path, so results never vary between queries
- Constant per-query cost regardless of memory size, even at 32,000 words
- No infrastructure to run—no vector database, cluster, or GPU needed
- Works with any model, so small local models gain the most from better retrieval
