A 10-year-old CNN outperforms frontier LLMs for skin cancer diagnosis
What happened
A dermatologist compared two leading large language models, GPT-6 Astra and Claude Fable 5.1, to a ten‑year‑old Inception v3 convolutional neural network on 200 biopsy‑proven skin lesions and found the CNN correctly identified the diagnosis for 62% of cases, while the LLMs each succeeded on about 42%. The CNN, fine‑tuned for about twenty minutes on public dermatology images, outperformed the frontier LLMs in recognizing skin cancer from paired clinical and dermoscopic photos.
Why it matters
The result suggests that older, specialized image‑analysis models can still surpass newer, general‑purpose language models in specific medical imaging tasks, highlighting the importance of task‑specific AI approaches.
