What you’ll find in the video
Jev returns probabilities for supplied choices, ordered scores, or yes-or-no propositions rather than conversational text.
The pricing shown in the video charges for input tokens rather than generated prose; check current provider pricing before budgeting an application.
Gary’s interactive examples handle simple sentiment judgments but fail on harder logic riddles and prime-number checks without external tools.
Worth knowing
Auto-generated English captions reviewed with Gemini. Gary demonstrates that Jev struggles with multi-step logical deduction riddles and large mathematical verifications because it evaluates states directly without executing code or chain-of-thought scratchpads.
