Born of deby-lite. Stripped to the bone. Built to run in 512MB.
d3b4 is a lean AI agent forked from deby-lite, purpose-built for constrained environments like Render.com free tier (512MB RAM).
d3b4 is Agent Zero at its core - intelligent, agentic, and API-connected - without the heavy extras.

d3b4 is a Web3 compliant AI agent that supports decentralized token-based inference — compatible with the venice.ai ecosystem.
| Token | Description |
|---|---|
| A0T | venice.ai ecosystem utility token for inference and compute credits |
| Diem | Stablecoin-backed token for inference payments and agent service transactions |
- Pay for LLM inference using A0T or Diem tokens
- Compatible with venice.ai decentralized inference marketplace
- Token-gated agent capabilities and compute tiers
- Wallet integration for seamless on-chain inference billing
- Works alongside traditional API key providers (OpenAI, Anthropic, etc.)

d3b4 builds upon deby-lite and Agent Zero by providing:
- A minimal footprint (~300MB) optimized for 512MB RAM environments
- Stripped of browser automation, Torch, TTS/STT for lean operation
- Purpose-built for Render.com free tier and similar constrained environments
- Web3 token inference compatibility (A0T + Diem) inherited from deby-lite
