Pi Durable EXPLAINED: Build Always-On Agents with Local Models

Pi Durable is a building block for always-on agent applications, not a new coding-agent CLI.

Then follow a local llama.cpp demo with Qwen3.5-0.8B, including a second script that resumes interrupted work from SQLite. The APIs are experimental and may change; tool replay safety and restarting the host process remain important application responsibilities. --- 🔗 *Links* - Tutorial companion code (fresh chat and restart recover
