Entraspan experiments with AI models from all the major companies

Problems arise because there are so many models to choose from
Often times free or near free is ideal for text generation
Some models are prohibitively expensive and to be avoided
The model lists may change, this list is cached for 24 hour intervals
Lower case attribute names are from the api, mixed case is added

What a Mess!

This is a work in progress, turned out to not be time consuming
Prooves the business guys and technical side are not talking
Claude is the worst maybe
- No consistency between pricing and model id
- Many models being returned with no pricing/info
On chatgpt and claude I marked anything not matched as legacy
Haven't attempted embeddings
Would be nice to get this information directly from the api's

Augmented model attributes

The model attributes often are missing, incomplete, or insufficient
Would be nice if there were standard attributes to compare models
That is what the purpose of this page is with a link to a json file
The added attributes help applications/users select ideal models
Moved chatgpt to the bottom cause of all the noise
Moved xai to the top as a leading frontier level model
