While I get the cost of hosting an LLM and a separate plan for unlimited usage is totally fair, I do think paying customers, especially subscribers to the so-called unlimited plans, should get a little special treatment with a tier of Lumo exclusive to these plans.

Perhaps instead of the 10/day and 200/month prompt limit, 1 project limit and 7 day history that Lumo Free provides, this new Lumo Lite could give us 50/day, 500/month, 2 projects and unlimited history (we already have 500 GB of storage so Lumo message storage should be negligible).

All the other features like unlimited prompts, projects and advanced AI models could be reserved for the Plus plan for those who need it, but having it easier to integrate in an existing 2 year plan, with appropriate discounts would be nice. Currently, upgrading to Lumo Plus while having Proton Unlimited, downgrades me to a 1 year plan for both, forcing me to pay more for Proton Unlimited as well.
