Gemini models · Google
Google's Gemini lineup, from Pro to the speedy Flash Lite, plus the Nano Banana image models, all in the same chat as GPT, Claude and the rest.
Every Google chat model Portail carries today, listed below.
The largest context window in the family, for long files and long chats.
Switch from Gemini to GPT, Claude, DeepSeek or anything else mid-conversation.
Gemini models are fast, handle very long inputs, and understand images well. Flash and Flash Lite are some of the cheapest capable models around, which makes them good defaults for everyday questions. Nano Banana is Google's image generation and editing line.
Pick a Gemini model from the model picker in any chat. It reads the whole conversation, including anything other models said earlier, and your Portail memory. When you want a second opinion, switch models and keep going, or turn on Council to ask several models at once.
Every plan, Free included, can use every Gemini model. Plans change the size of your monthly credit allowance, not which models you can pick. Bigger models use credits faster; the cost band in the table shows roughly how fast.
