Agent-Zero has basic tool use, but is set up to code it's own tools as requested . No code tool development to solve your problems. With basic search, memory, and terminal use built in, including executintg code, it will build tools to solve your problems. Interesting for personal use, especially with GPT-4o mini out, and Llama3 405B. Agent-Zero will spawn his own sub-agents if neccesseary. No need to code an agent crew, if needed. Agent-Zero will do it itself.
