Episode notes
GPT‑5 Is A Consolidated System
- OpenAI consolidated earlier models into GPT‑5 with routing and feeder upgrades.
- It is more reliable but not a dramatic leap forward.

- OpenAI shifted safety to focus on the model's generated output rather than pre‑classifying user intent.
- That yields fewer blanket refusals and more targeted redaction of dangerous details.
Task Doubling Accelerated To Months

- Extrapolation implies month‑long autonomous tasks by around 2028.
