100-word summary
Notion just baked GPT-5.4 into its model picker, giving users access to OpenAI's latest knowledge-work model. The upgrade cuts false claims by 33% and full-response error rates by 18% compared to GPT-5.2. On OpenAI's GDPval benchmark spanning 44 occupations, GPT-5.4 hit 83% accuracy versus 71% for its predecessor. The presentation upgrade is striking: human raters picked GPT-5.4 outputs 68% of the time, citing better visuals and aesthetics. Investment banking modeling tasks jumped from 68% to 87% accuracy. The catch? Notion hasn't disclosed sample sizes or methodology, so real-world mileage will vary. Still, fewer revision rounds on decks and docs means less time babysitting AI.
