We tested Jev 1.13 as a router for 200 Banking77 card messages with 10 intents, reached 0.985 accuracy with option descriptions, and used its confidence to pick an auto-answer cut-off that still covers 90% of messages.
Hosted Jev 1.13 scored 0.970 and Laya on a local RTX 5090 scored 0.875 on the same 10-intent question over 200 bank card messages, while Laya answered one request in 20.5 ms against 654 ms for Jev.

I really like this course. It explains AI step by step in a simple and clear way. This should be the first course anyone takes to truly understand AI.
This is the only course which finally teaches how to fine-tune your own LLM.
Great content, comprehensive code documentation, flow and topic selection. Laxmi provides a good learning experience.
The course is very excellent especially to start learning llms.
