A new Epoch AI report by Emberson and Roodman finds that the price of achieving a given level of AI performance has dropped roughly 47% per quarter over the past three years, a 13-fold annual decline. The report cites OpenAI's o3, which cost about $0.30 per question to score 75% on GPQA Diamond in January 2025, compared with a much newer model reaching similar scores for a fraction of a cent by mid-2026.

A new benchmark comparing OpenAI's GPT-5.6 Luna and GPT-6 Astra on code review found Luna verified 69 bugs across 50 pull requests versus Astra's 92, while costing roughly 28 times less per review. Luna also produced more false positives, with 24 of 93 flagged issues failing verification compared to Astra's 4 of 96, and it caught fewer security-related bugs.

A tech commentator reports extensive hands-on testing of GPT-5.6-Luna, a fast small AI model that processes complex tasks—like scanning thousands of emails—for only tens of cents per query. The author also notes GLM 5.3 as another efficient option now competing at the frontier of cost-versus-capability, arguing that these smaller models have quietly closed much of the gap with premium models like Fable 5.
