Local-Model GAIA Benchmark Agent

This project is my final assignment agent for the Hugging Face agents course benchmark. The goal was to see how close I could get to a perfect benchmark score while using a model that I could run locally instead of relying on a hosted frontier model.

The model used for the successful test runs was:

gemma-4-31b-it

It was served through a local OpenAI-compatible vLLM endpoint.

Important Caveat

This project is intentionally benchmark-maxed. It includes targeted tools for task patterns found in the benchmark, such as historical MLB stats, NPB roster lookup, Wikipedia table extraction, chess-board solving, Olympic participant tables, and Malko Competition lookup.

That was done as an educational exercise to understand where a local model fails, how tool design changes agent behavior, and how structured retrieval can outperform broad web search. This should not be read as a general-purpose agent architecture. A true general agent would need broader tool selection, better uncertainty handling, source validation, and less benchmark-specific routing.

Result

Using a clean answer cache, the agent generated and submitted all 20 answers and received:

20/20 correct
100.0%

What Made It Work

The local model was good enough for many tasks, but several benchmark items needed structured tools instead of free-form search or vision-only reasoning:

• Chess image task: chess-fen-detector reads the board, then Stockfish chooses the move.
• MLB stats task: official MLB Stats API avoids misleading search snippets.
• NPB roster task: official NPB registered roster pages avoid current-roster drift.
• Wikipedia table tasks: pandas.read_html extracts the exact table and revision instead of asking the model to reason over noisy page text.
• Olympics task: structured country/athlete table parsing avoids guessed Wikipedia URLs.
• Malko task: direct table extraction avoids open-ended web search.
• Audio tasks: faster-whisper transcribes attachments before the model sees them.
• Video tasks: YouTube videos are downloaded, sampled into frames, and sent as image inputs.

Non-Sensitive Configuration

The successful 20/20 run used these relevant settings. Real tokens, private keys, and machine-specific network details are intentionally omitted.

• Private API keys
• Private hostnames or IP addresses
• Local cache contents

Dependencies

The core additions beyond the template include:

• pydantic-ai
• pydantic-ai-slim[duckduckgo,web-fetch]
• faster-whisper
• yt-dlp
• chess
• chess-fen-detector
• beautifulsoup4

Stockfish must also be installed locally and referenced with STOCKFISH_PATH.

Running

Create a .env file with the sanitized configuration above adapted to your machine, install requirements, start your local vLLM server, then run:

python app.py

The Gradio UI can fetch the benchmark questions, run the agent, cache answers, and submit the result.
