The article analyzes the launch of Anthropic's Claude Opus 5, highlighting its "Fable-level" performance despite official benchmarks placing it slightly below Fable 5. Independent evaluations and user feedback suggest significant overperformance, particularly in coding and agentic tasks, where Opus 5 excels.

The debate focuses on the limitations of current benchmarks, which struggle to capture practical improvements and the "big model smell." Inconsistencies in evaluations, such as better performance at medium effort than at high effort on certain tests, highlight the complexity of measuring the capabilities of cutting-edge models. The article emphasizes the need for more robust benchmarks adapted to agentic uses.

In parallel, the article addresses other key topics in the AI ecosystem, such as the importance of open models for sovereignty and innovation, security incidents related to autonomous agents, advancements in training methods and infrastructure, as well as comparisons between competing models and the challenges of integrating AI into businesses.
