Latest general-purpose AI models recorded lower accuracy than Google’s Inception v3 image recognition model released in 2016 in a skin lesion diagnosis experiment. Researchers compared GPT-6 Astra, Claude Fable 5.1 and Inception v3 using 200 lesion images split between cases needing treatment and those requiring no action. Inception v3 led overall and in melanoma identification. The study said differing training conditions limited interpretation and larger validation and safety assessments are needed for clinical use.

Competition in AI wearables is spreading beyond familiar formats to necklace-style pendants, rings, wrist devices and portable terminals. Products range from productivity-focused devices that record and summarise meetings and calls to AI companions that respond to users’ emotions. Recently launched or in-development devices highlight functions such as conversation logs, scheduling, personalised advice and emotional support. Pricing, privacy features and integration with smartphones are cited as key factors shaping market leadership.
