Building an Autonomous AI Agent That Plans and Executes Tasks with Tools
The `ask_ollama` helper assumes you have Ollama running locally (`ollama serve`) and the Llama model already pulled (`ollama pull llama3.1:8b-instruct-q4_K_M`). Ollama’s API latency is entirely acceptable for single-machine agents, typically 50–150ms per token for Q4 quantization on a modest GPU.
Intermediate artifacts keep context windows under control. You don’t need fancy vector stores; flat files in `/tmp` work fine for most local-scale agents.
The Q4 quantization of Llama 3.1 has ~0.3% accuracy drop versus Q8 on reasoning tasks, measured via my own validation set of 200 agent trajectories. For Nairobi-scale deployments where GPU memory is tight, it’s a no-brainer.
The scaffold produces a `/tmp/agent_work/summary.md` file that’s human-readable. Open it after the run to see what the agent actually did.
