nextpy

Why we included this project

Nextpy is a pure-Python framework for developers building AI applications where the model itself influences the app's code and behavior. Its core is a compile-time prompt engine that gives you structured, typed control over LLM output: guardrails that define what the model can and cannot do, exact response schemas, session state with reused KV caches, and speculative sampling to speed up generation on open-source models. That focus on deterministic output makes it a better fit for agent backends and code-generation tools than for a general-purpose chatbot. It also includes a generative UI layer, so you can build the front end of an agentic app without leaving Python. The project is still explicitly an experiment, marked as being in the "just for friends" stage, so treat it as something to prototype with and test against your own prompt-heavy workloads, not a battle-tested platform.
