:llama: Llama.cpp’s Web UI Just Graduated — No More Preview Mode

:world_map: One-Line Flow:
After months in preview, llama.cpp now ships a stable, built-in web UI — clean, fast, and finally ready for humans.

For :donkey: 1Hackers

  • Don’t worry, this is the update that finally lets you play “ChatGPT” on your own PC — no cloud, no login, just pure nerd magic. :high_voltage:

:gear: What’s New

The new interface is SvelteKit-based, rewritten by Alek (allozaur) — one of llama.cpp’s core devs.
It’s a full migration from the old React preview that started back in September 2025 (PR #14839).
Now, in November 2025, it’s officially stable — no more nightly builds or half-broken previews.

:puzzle_piece: Killer Features

Here’s why it’s not just another chat box:

  • :speech_balloon: RAG mode: Upload text, PDFs, or images — it chats with your docs directly.
  • :brain: Smart paste: Long text? It auto-saves as a file.
  • :eye: Vision models: Drop an image and it actually understands it.
  • :open_file_folder: File manager: Upload, preview, convert (SVG, WEBP, text — all supported).
  • :thread: Chat branching: Conversations split into trees — no lost context.
  • :high_voltage: Shortcuts:
    Ctrl+Shift+N → New chat
    Ctrl+K → Search
    Ctrl+B → Toggle sidebar
  • :bookmark_tabs: PDF dual view: Text extraction + side-by-side pages.

Basically, it’s ChatGPT-style polish, but local and open-source.

:toolbox: How to Run

  1. Update to the latest llama.cpp build.

  2. Launch the server:

    ./llama-server

  3. Open your browser → 127.0.0.1:8080

That’s it. No dependencies. No cloud. Just vibes.

:balance_scale: Ollama vs Llama.cpp

  • Llama.cpp Web UI:
    Lightweight, local, plug-and-play.
    Great for quick chats and RAG workflows.

  • Ollama:
    Handles model downloads, loading/unloading, and Modelfiles better.
    Perfect for managing multiple models or complex setups.

Both are great — pick your poison.

:firecracker: Quick Notes

Some users say it’s missing multi-agent handling — true.
For that, check ExLlama or vLLM (they handle parallel workloads better).

(ಠ‿ಠ) Girllll… another AI update? Fine. But can it pay rent this time?

Because if not, I’m installing it on my toaster and calling it a startup.

  1. Local ChatGPT Clone Seller

    • Turn the new Web UI into your own “Private AI Assistant.”
    • Add a name, logo, PayPal button — done.
    • Sell it to small business owners scared of cloud AI.

    :light_bulb: Example: A café in Lisbon offers “Ask-AI” on their website — built on llama.cpp — to answer tourist FAQs, menu questions, and local tips.

  1. Digital Product Farm

    • Use RAG to turn old PDFs into new digital gold.
    • Upload → chat → reformat → sell as guides or eBooks.

    :light_bulb: Example: Someone in Vietnam repackaged public-domain cookbooks into 100-recipe themed PDFs and made $600/month on Etsy.

  1. Privacy Freaks Market

    • Market it as “no spying, no cloud.”
    • Sell your local AI app to privacy nerds on Gumroad or Reddit.

    :light_bulb: Example: A guy in Germany sold an offline “Private ChatGPT” build to therapists and lawyers for €49 — no logins, no tracking.

  1. Custom PDF Chat Bots

    • Offer “AI Doc Explainer” gigs — upload client docs and turn them into bots that can answer questions.

    :light_bulb: Example: A freelancer in Brazil made a bot that explains UN visa forms in Portuguese — now used by travel agents.

  1. Resume & Cover Letter Factory

    • Feed in a person’s details, let the AI format and rewrite professionally.
    • No API fees, no limits, no waiting.

    :light_bulb: Example: A woman in Kenya sells $10 resume bundles to job seekers on WhatsApp, built entirely on llama.cpp.

  1. Café / Library Setup

    • Install it on public PCs as an “Ask-AI Desk.”
    • Run local ads or attach a QR donation link.

    :light_bulb: Example: A library in Poland added a “Research Helper PC” — locals pay small tips via QR for every session.

  1. The Pretend Hacker Route

    • Rebrand it as a “local LLM lab.”
    • Charge $5/month for early access to your “AI sandbox.”

    :light_bulb: Example: A Discord mod in the Philippines runs a “beta tester” group with 300 members — using free llama.cpp builds.

:skull: In short:
llama.cpp’s Web UI isn’t just a nerd toy — it’s an ATM in disguise.
All it takes is a bit of imagination and one command:
./llama-server

:skull: In Short

The web UI isn’t “new,” it’s just finally done right.
Alek rebuilt it from scratch, made it fast, stable, and smart.
Now llama.cpp isn’t just for coders — it’s for everyone.
