Add Kimi K2 thinking
huggingface.co moonshotai/Kimi-K2-Thinking
Hi! would make sense to have it as a main OSS model as it is the SoA (the most "intelligent" one that is also open source!)

Multiple Personalities - more control & community templates
Currently, under the 'Personalization' you can create ONE personality per user. Depending on my task at hand I need more control over the expected output. As currently there is not really a good way to configure the expected outcome. (e.g. how 'creative' the model can be or how strict it needs to adhere to the input).
This feature would also really benefit from (community) templates which must be editable for better control.

Improved visibility of the Internet search icon in Lumo
I find the current icon for the integrated Internet search in Lumo difficult to distinguish, especially with dark themes or low screen brightness. I suggest introducing a clearer, higher-contrast icon that automatically adapts to the selected theme (light/dark).
Possible implementation:
A minimalist magnifying glass icon with a subtle frame that is highlighted in color when search is activated.Optional: A short tooltip display (“Start/stop search”) when pressed and held to support new users.
A clear icon makes it easier to find and activate the search function, which increases the overall usability of Lumo.

I want to be able to use Lumo using the latest Firefox Extended Support Release (ESR) version
I want to be able to use Lumo using the latest Firefox Extended Support Release (ESR) version, so that I can continue to use Lumo on my company notebook that does not support other browser brands.
Since yesterday (1 Nov 2025) I receive a message that says "Unsupported browser". There has been no communications to inform us that the Firefox Extended Support Release (ESR) version will no longer be supported. Our browser version is fully up-to-date, at the time of writing it is 115.29.0 Firefox ESR October 14, 2025 and no newer version of Firefox ESR has been released at…

Disclose weekly limits
At present, Lumo has a weekly limit on the free tier. The problem is, a user has no idea what this limit is, and only find out when they hit it. They also don't know what it'd reset. Proton should be providing transparency on this, not just a "surprise, you hit quota, buy or come back after some undisclosed period of time".

Multiple Lumo agents
Now that its possible to personalize Lumo, I also wish for the opportunity to create multiple different Lumo Agents, so I could for example have one developer agent, one recipe agent and so on.

Better Mathematical Expression Display
Currently, the mathematical expressions produced by Lumo in responses, are not legible. They are generally in raw latex syntax, which is absolutely unsuited for display purposes. They should be rendered either as legible plain text (probably bold-faced for distinctiveness) or as document-typeset graphic math expressions.

Personalization bug in Lumo
Thank you so much for adding personalization into Lumo! This was the main reason for me to not use it until now. Meanwhile, the personalization only applies to the first response. All next one doesn't include it, and same when regenerating.

Improving response quality and reducing bias
As it is, Lumo doesn't work very well.
It hallucinates facts more often than other modern models that also don't access the web. When asked about privacy-related questions, it almost always promotes Proton's services (including ones that don't exist such as "Proton Chat"). I understand that there is an incentive to promote the company's own services, but most people interested in a privacy-respecting LLM, and especially those willing to pay, don't want it to act as a shill for Proton.

Accept all text files, independently of their extension name.
Lumo is able to read and understand many text-based files (LaTeX, json, python, etc...). However, only .txt files can be uploaded (files without .txt extension name are refused). It would be nice to accept a larger set of file, as Lumo is able to read them once renamed with a .txt. Lumo shall be able to recognize them correctly, without enforcing in the chat was format is intended to be the submitted file.

Use better open-source ai models.
Dear Proton Team,
I would like to propose integrating several high-quality open-source AI models into the Lumo platform. These models align with Proton’s core values of privacy, transparency, and user data sovereignty, while offering excellent performance and flexibility.
The recommended models include GPT-OSS 120B, LLaMA 3, DeepSeek-V3, Mistral 8x22B, and BLOOM. These models stand out because they are open source, enabling complete self-hosting and customization. This means Proton can maintain full control over user data, keeping all processing within secured European data centers, aligned with Proton’s zero-access policy and strong privacy commitments.
GPT-OSS 120B offers powerful capabilities close to proprietary…

File types and size / unsupported file types
The current file types to upload f.e. images don’t work well and constantly I’ll get the message of “unsupported file type” in the pop-up window and that’s a false flag. They are all files types that Lumo support. I can open those files without any problems within Proton Drive or iCloud. Same issue occurs on Windows desktop, iPhone and iPad. Drag and drop makes no difference.
The file size is also an issue, limited to 10MB and I have a subscription. An average photo is already more than that. Files stored in Proton Drive can be uploaded with a maximum…

Feature Request: Exclusive Access to Larger LLMs for Lumo Plus Subscribers
I would like to propose a feature specifically for paying Lumo Plus subscribers: the ability to enable Lumo to use larger LLMs (such as GPT-5, GPT-5 Thinking, Gemini 2.5 Pro, Grok 4, Claude Sonnet 4.5, etc.) for processing queries. The core idea is for Lumo to act as a privacy barrier—protecting user data—while still taking advantage of the advanced capabilities of top-tier models for those who subscribe.
This enhanced feature should be strictly limited to users who actively pay for Lumo Plus. Free users would continue using the current models and would not have access to this option.
