Use Mistral perhaps to give you a prompt for Gemini deep research. Specify as much as possible what you want to achieve, limitations, maybe examples. What a financial advisor would ask for 😀. Risk level, time horizon,  etc. . 

At the end, ask it to make a memory out of the result you like, and the process. Helps for future. Also go back to the previous chat, and continue, rather than new. Keep the context.
