BubbaBuilt GPU Network
Affordable, easy-to-use OpenAI-compatible AI API for cheap LLM calls and app integration — powered by a decentralized GPU network where anyone can rent out an idle GPU and earn USDC on Base.
Low-cost AI for developers and businesses. Inference runs on a community GPU network instead of expensive hyperscale data centers, so API calls stay affordable. Paid plans start at $29/month.
Drop-in OpenAI-compatible chat completions endpoint. Change the Base URL and API key in your existing SDK, tool or app — no rewrite needed.
Free guest chat right on the home page, simple API keys, clear usage dashboards and request logs. Get started in minutes without DevOps or GPU setup.
Access popular open-source models — Llama, Qwen, Mistral, Gemma and more — with smart routing to the best-fit model running on the network.
Prompts and answers are not permanently stored; only SHA-256 fingerprints are recorded. Team seats, spend limits, budgets, rate limits and webhooks scale from side projects to enterprise.
Turn a gaming PC or workstation into passive income. BubbaBuilt sends real AI chat and photo jobs to your graphics card, and you earn rewards for every verified answer.
Ethereum GPU mining is gone, but AI compute is growing. Instead of hashing, your GPU runs open-source language models and earns USDC for useful work.
Rewards are tracked in a transparent ledger and paid in USDC on the Base network on a weekly schedule, with every payout block visible in the public Explorer.
Our free miner sets up Ollama, checks your VRAM and drives, and lets you pick from a catalog of permissively licensed Hugging Face models — Llama, Qwen, Mistral and more.
No GPU? Phones can answer short text jobs with a tiny on-device model and earn rewards right from the browser — no app store download.
Join the Compute Pool to share rewards equally with other verified online GPUs, or mine solo and keep every job you win.
Yes. BubbaBuilt routes real AI jobs to your GPU. The first correct, verified answer earns the reward, which is credited in USDC and paid out on Base.
Any modern NVIDIA or AMD card that can run Ollama works. More VRAM lets you run larger models and earn photo and long-job bonuses.
Payouts run every Wednesday at 5 PM Central, or early after 1,008 work blocks. Network fees come out of the reward.
BubbaBuilt never asks for your wallet's private key. You only add a public Base wallet address to receive rewards.
Yes. Because jobs run on a community GPU network instead of costly data centers, LLM API calls are affordable, with paid plans starting at $29/month and free guest chat on the home page.
Use any OpenAI-compatible SDK: set the Base URL to https://bubbabuilt.app/api/public/v1, use model bubbabuilt-chat, and add your API key as a Bearer token.
No. Prompts and answers are not permanently stored; only SHA-256 fingerprints are kept for verification.
The miner is free to download. You only pay for your own electricity.
