Speaking of the devil - I've just had hallucinations with Ollama and reader-lm model (converting HTML to Markdown) the other day. In 40% of cases it spew out things that weren't in the input (not exactly surprising, knowing that it's a generative model).

Turns out the model needs temperature of zero (and then it seem to behave well, at least in simple tests), but it wasn't in the model settings.
