Cmpnd released dspy-wsp, a prototype optimizer that adds weight‑space programming to the DSPy framework. A frontier LLM – a large language model – reads a small model’s weights, edits them in a sandbox, and evaluates each change without using gradients. Each test run costs roughly $5 to $10. The tool is currently a prototype and not yet a commercial product.

## The facts

- Release date: 2026‑11‑14
- Run cost: about $5–$10 per test

## Why it matters

Developers can experiment with model weight edits cheaply, opening new ways to fine‑tune AI without traditional training.
