## Summary

Jeb, a new AI model from the creators of InstructGPT, is designed to give only classification answers such as "Yes/No" or a numbered choice, skipping free‑form text. Reported by Tomohiro Ikeda on his YouTube channel, Jeb is said to be up to 200 times faster and 400 times cheaper than existing AI, with a response time of about 0.1 seconds.

Ikeda demonstrated Jeb by comparing it to a cheap GPT model on tasks like refund status checks and call‑routing decisions. Jeb returned results in about 0.5 seconds, roughly 3‑4 times faster, while keeping classification accuracy nearly identical. He also integrated Jeb into a slide‑generation tool, showing that a process that used to take 10 minutes could be reduced to about 1 minute.

The video also covered other industry updates: Anthropic’s report that AI accounts for 26% of its R&D, Claude’s consolidated entry points, Gemini Notebook’s new voice and video features, and OpenAI’s plan to discontinue custom GPTs on December 11. Small‑business plugins for Claude now include 43 workflows and 27 integrations, and Meta announced a new “Meta One” plan for cross‑platform AI use.

## Key points

- Jeb returns only classifications, up to 200 times faster and 400 times cheaper than existing models
- Anthropic reports AI drives 26% of its R&D tasks
- OpenAI will discontinue custom GPTs on December 11, moving them to read‑only skills

## Why it matters

The Jeb model offers a lightweight, high‑speed alternative for decision‑making tasks, potentially reducing costs and latency for AI‑powered workflows. Its release signals a shift toward specialized, efficient models that can be embedded in agents and business tools.
