Add model reliability ratings to README

Hi,

First of all, thank you for this project!

Would it be possible to add a section to the README listing the models that tend to work reliably?

After trying several of the available models, I noticed that some of them don't always work (someone never). Having an indication of which models are more reliable could help users save time when choosing a model.

For example, you could use a simple rating such as:

• 8/10 — Usually works, occasional errors
• 5/10 — Works sometimes, but errors are relatively common
• 2/10 — Rarely works / frequent errors

This could be based on community feedback or your own testing.

Thanks!
