7 OpenAI Commits 80–90% of Research to GPT-7 Development¶
OpenAI's Head of Applied Research Boris Power stated that 80–90% of the company's research effort is directed toward GPT-7, GPT-8, and beyond, as incremental improvements within generations are considered short-term, whereas new model generations provide 'real leaps.' Power noted the main challenge is user onboarding rather than model quality.

- Incremental improvements (e.g., GPT-5.1 to 5.2) viewed as 'extremely shortsighted'
- New generations provide 'real leaps' where everything works better
- Main challenge is user onboarding, not model quality
- GPT-4 required careful prompting; GPT-5 easier; GPT-6 functions like capable colleague
