Gemini seems to have the best free "Deep Research" AI model at the moment. In part because its used in combination w/ their best reasoning model. Most other deep research tools ive tried (1) do extensive research, (2) process that data, then (3) produce an output. Gemini implements reasoning and does multiple queries.
Check out how much more complex Gemini's research is. It searched over 200 sources, including YouTube (both owned by Google). See the rest in the comments #ai
