It would be awesome if we could see, side by side, answers by different LLMs to the same prompt (eg. Chatgpt, deepseek and Claude) and choose the best one to follow up the conversation.
Also, I would like to have access to the best OpenAI models, especially reasoning and the one that generates images. That's what keeps me paying for ChatGPT instead of the Kagi Assistant.
User could send a prompt, and the assistant returns, side by side, multiple LLMs answers to that prompt. The same happens for every new prompt inside the same conversation.
User could use best OpenAI best reasoning models for a deeper thinking process. Or generate images from prompts.
