How to exclude (blacklist?) some words during generation?

[SuperMasterBlasterLaser]

Hello everyone. I have discovered this package that really what I needed. However, I have encountered one challenge that I cant solve.

Lets just say we gave model prompt to generate some text:

prompt = "<s>[INST]Give short description.[/INST]"
generator = outlines.generate.text(model)
result = generator(prompt, max_tokens=25)

It will generate some text, but it will contain words that I don't want to be used in text. How to make generation ignore some list of words. I though that using regex will help. I had changed my code into this:

generator = outlines.generate.regex(model, r"\b(?!words|to|ignore\b)\\w+")
result = generator(prompt, max_tokens=25)

However, it throws an error:

interegular.patterns.Unsupported: Escape \b is not implemented

Is it even possible to force generation ignore some words?
