A private chat atelier running on NVIDIA GPT-OSS 120B — 120 billion parameters, streamed to you a token at a time.
A chat workspace that actually thinks with you.
Brbr L4 runs on NVIDIA's GPT-OSS 120B through the NIM API. Stream answers token by token, hand it files, images or your voice, and let it remember the things worth remembering — all in one fast, keyboard-friendly interface.

Summarise this spec and turn it into a build plan.
Here's the plan, split into three shippable slices — starting with the data model, then the streaming layer.
for await (const chunk of stream) {
answer += chunk.content
}
Everything included
Built for real work, not demos
Token streaming
Answers appear as they are generated, with a stop control that keeps whatever was already written.
Conversation history
Every thread is stored, auto-titled from its first exchange, and can be pinned, renamed or deleted.
Markdown & code
Full Markdown with GitHub tables, syntax-highlighted code blocks and one-click copy on every snippet.
File understanding
Drop in PDFs, documents or code — the text is extracted server-side and fed straight into the prompt.
Image reading
Upload an image and its text and layout are transcribed before the model ever sees your question.
Voice input
Hold a thought, speak it, and it lands in the composer transcribed and ready to send.
Long-term memory
Useful details are distilled after each turn, then reused in later chats. Editable and switchable at any time.
Regenerate
Not happy with an answer? Re-roll the last turn without retyping anything.
Tunable
System prompt, temperature, top-p, max tokens, streaming, memory and theme — all in one panel.
Key stays server-side
The NVIDIA credential lives only in server environment variables — never in the browser, the UI, or any client request.
Straight to NIM
Every reply is a real call to integrate.api.nvidia.com — no canned responses, no mock layer.
Works on your phone
A responsive layout with a slide-over history panel, thumb-friendly controls and dark or light themes.
Open a thread and start talking
No account, no setup. Your chats, memories and preferences stay tied to this browser.
