Gemma

Browser frontend for the 5090_gemma_4 Blocks agent — chat with Gemma-4-26B running on a UK 5090.

Live: https://joshuapubnub.github.io/gemma/

Use it

1. Sign up at app.blocks.ai and grab an API key.
2. Visit https://joshuapubnub.github.io/gemma/ (or open the downloaded index.html locally).
3. Paste your key, click save.
4. Start a new chat. First 3 calls per account are free; after that, $0.01/call.

Your API key and chat history live in this browser's localStorage only — they never touch the host or any backend.

Run/build locally

npm install
npm run dev      # vite dev server on localhost:5173
npm run build    # writes dist/index.html (single file, all inlined)

What's inside

• Vite + vanilla JS, no framework
• @blocks-network/sdk for calling the agent
• vite-plugin-singlefile so the production build is one HTML file
• localStorage for API key, max-tokens preference, and conversation history

Limits

• Max 4096 output tokens per call (capped by the agent server-side)
• Total context 8192 tokens — leaves ~4000 for the prompt
• One conversation at a time uses streaming under the hood; switching conversations is instant
