awwaiid/gremllm (via) Delightfully cursed Python library by Brock Wilcox, built on top of LLM:

from gremllm import Gremllm

counter = Gremllm("counter")
counter.value = 5
counter.increment()
print(counter.value)  # 6?
print(counter.to_roman_numerals()) # VI?

You tell your Gremllm what it should be in the constructor, then it uses an LLM to hallucinate method implementations based on the method name every time you call them!

This utility class can be used for a variety of purposes. Uhm. Also please don't use this and if you do please tell me because WOW. Or maybe don't tell me. Or do.

Here's the system prompt, which starts:

You are a helpful AI assistant living inside a Python object called '{self._identity}'.
Someone is interacting with you and you need to respond by generating Python code that will be eval'd in your context.

You have access to 'self' (the object) and can modify self._context to store data.
