 1. **Google's [FRAMES](https://huggingface.co/datasets/google/frames-benchmark)**: This is the primary evaluation benchmark we tested against. It tests:
-   - Multi-hop reasoning: Requires retrieval from multiple sources and reasoning over them.
-   - Temporal reasoning: Requires reasoning about time.
-   - Tabular reasoning: Requires reasoning on data in tabels.

+#### Evaluated Modes
+Khoj can be interacted with in a few different modes. The 3 main ones from the lens of the evaluations are:
 - **General**: This is like a closed book exam. No retrieval is allowed. The agent can't access external information, only the LLMs existing *general* knowledge.
 - **Default**: This is like an open book exam. Single shot retrieval is allowed. The agent can search for information online, run calculations in a [code sandbox](/posts/ai-with-code-execution).
-- **Research**: This is like a take home exam. Iterative retrival is permitted. The agent can do deeper research for a bit longer with the same web search and code tools.

 ### Results
 
-These runs evaluate Khoj with gemini-1.5-flash-002[^5] on a 200-question random subset of the target benchmark. This results in error margins of ~6% at reasonable costs ($5 across the 3 modes and 2 benchmarks).

 ### Future Work
 - Add ability to efficiently test retrieval across internal and external knowledge. Our current eval only measures retrieval from the internet, not from your documents.
