Ask HN: How are you choosing the model when using pi.dev?

1•harlequinetcie•1h ago
I've been using pi.dev for a while, and I find myself choosing the models based on anecdata.

I would love to be a bit better at it, and I did try a few of these 'battle of models' websites, but couldn't find much.

I'm interested on knowing your experience when selecting a model for different parts of your agentic SDLC.

Thus far, I'm using + sonnet for code reviews. + haiku for code searches/analysis. + flash 3.5 when LLM as judge is required + Opus to generate content. + K2.5 seldomly as alpha testing (right now for unti test generation is ok)

Ideas?
