By skyforbes I use gemini deep research for financial stuff (mostly stock market DDing) Ive noticed a significant downgrade. It no longer sources anything throughout the report only using sources from stuff ive uploaded. It also seems to of cut down the report lengths significantly often missing things i explicitly tell it to include (Im guessing due to the length constraint)
Very unhappy with it as this is the only reason why I use gemini. Not interested in image or video creation. Gemini 2.5 was leaps and bounds better
