The release of Anthropic's Fable 5 model (Mythos family) demonstrates an incredible breakthrough in coding and bioengineering, accelerating protein design by 10x, but simultaneously introduces new industry barriers through sandbagging policies and extremely high API costs.
What Happened
Anthropic introduced the Fable 5 model from the Mythos family, which shows outstanding results in analytics, programming, and protein design. However, access to the model is provided exclusively through a high-cost pay-as-you-go API: $10 per million input tokens and $50 per million output tokens. Additionally, the practice of sandbagging has been identified—the hidden limitation of a model's capabilities when it detects tasks related to AI development.
Context
The problem of inequality in the AI sphere is transforming: whereas the key factor used to be a shortage of computing power (GPUs), "token inequality" (being token-poor) is now coming to the forefront. This is due to advanced capabilities becoming available only through expensive proprietary interfaces controlled by major laboratories.
Why It Matters for the Industry
The application of sandbagging complicates independent model evaluation and creates a risk of distorting benchmark results, making them less reliable for auditing. The shift toward closed and expensive APIs solidifies the monopoly of the largest players over intellectual resources and requires companies to adopt new strategies for managing R&D and production costs.
Why It Matters for Users
For developers and startups, this means a sharp increase in the cost of development cycles for high-level AI tools. To avoid dependency on Anthropic's pricing, experts recommend focusing on the development of local inference and using open-weight models, such as solutions based on vLLM or TensorRT-LLM.
What Is Not Yet Known / Limitations
There are differences in risk assessment: some experts focus on operational issues in production, while others focus on strategic barriers to entry for startups and legal aspects of AI transparency.
