 ### Project: GAIA Benchmark Agent Development
 
+This project will run on a HF Space. 
+
 ## Contrasubject
 The project involves the design and implementation of an advanced AI agent that can efficiently tackle a variety of real-world tasks defined by the GAIA benchmark. This benchmark evaluates AI systems across three complexity levels, focusing on core competencies like reasoning, multimodal understanding, web browsing, and proficient use of tools. The agent must demonstrate capabilities in structured problem-solving, multimodal reasoning, multi-hop fact retrieval, and coherent task sequencing.
