What is the precision of the models on Amazon Bedrock?

You should look for this information from the model providers. Amazon Bedrock hosts the models and makes them available as an API call but the models themselves come from the individual companies/organizations. AWS does not alter the models, just hosts them on powerful infrastructure for easy use.

Hope this helps!

Amazon Bedrock offers a marketplace where you can quickly and safely access 3P models using APIs (more like a wrapper). As an illustration Similar to using several gaming machines in a game parlor to play or enjoy, however these machines are owned by different suppliers. On the website of the providers, you may obtain precision and other pertinent publicly available information about these models.See, for instance, https://mistral.ai/news/mistral-large-2407/ for Mistral.
