From the speaker
- lots of progress
- discovering potential applications
- putting GPT-4 class models into practice
Our interpretation
- The birthday context describes progress during GPT-4's first year.
- The plain reading is meaningful progress in multiple practical applications and actual user-facing implementations.
- The claim does not require most businesses to have adopted these models, mature autonomous operation, or demonstrated profitability.
- GPT-4 itself qualifies without needing to define the boundary of 'GPT-4 class'.
Counts as supported if: Dated records document multiple distinct useful applications and implementations made available to real users during the target period.
Counts as contradicted if: The purported progress consists only of hypothetical applications or announcements without actual implementations, or reliable records show that the claimed implementations did not occur.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported
The dated evidence matches what the claim committed to, under the criteria frozen before grading.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
Primary records document GPT-4 applications in education and accessibility, with released features and substantial real-user testing. These examples support meaningful progress in discovering uses and putting models into practice. Beta status and limited initial availability do not defeat this claim, which does not assert universal adoption or mature reliability.
Limitations
- The sources are reports from the deploying companies.
- These examples do not measure economy-wide adoption, long-term effectiveness or profitability.
- Be My AI remained an evolving beta product.
Evidence (2 items)
Supports the claim: Duolingo,
Duolingo Max uses generative AI
Why it matters here: The announcement identifies GPT-4-powered conversation practice and answer explanations, available immediately through Duolingo Max in selected iOS markets. This documents distinct educational applications implemented in a released product.

Supports the claim: Be My Eyes,
over 19,000 blind and low-vision beta testers
Why it matters here: The company identifies its assistant as GPT-4-powered and reports actual testing followed by an open-beta rollout. Documented uses include reading appliance controls, describing images and accessing written instructions, supporting both application discovery and practical implementation.
