Luo Fuli, head of Xiaomi’s MiMo large model team, said Anthropic’s Claude Fable 5 remains an interim-stage product, even as the model has drawn attention for its coding and agent capabilities.
Luo made the comments while discussing Fable 5 at the eighth Beijing Academy of Artificial Intelligence (BAAI) Conference, held on June 12.
Anthropic launched Claude Fable 5 on June 9, describing it as its most capable generally available artificial intelligence model and saying it was built for demanding reasoning and long-horizon agentic work. The company said the model showed state-of-the-art performance on nearly all tested benchmarks, with particular strength in software engineering, knowledge work, vision, scientific research, and other complex tasks.
In one example cited by Anthropic, Stripe reported that Fable 5 completed a codebase-wide migration in a 50 million-line Ruby codebase in one day, a project that would otherwise have taken a full team more than two months by hand.
Luo said Fable 5 marks a substantial improvement in coding and agent capabilities, but she argued that it is still best understood as the result of continued scaling across three dimensions:
