## Resource

Enterprise AI adoption often fails in the 'last 5%' due to reliability and cost issues that scaling alone cannot solve. This discussion explores 'adaptation'—a layer of gradient-free, inference-time techniques designed to bridge the gap between static foundation models and production-ready applications.

## Highlights
- Main idea: Scaling foundation models hits a wall in enterprise settings because they lack the reliability needed for the final 5% of use cases
- Practical takeaway: Moving from expensive fine-tuning to gradient-free, inference-time adaptation can significantly lower the unit cost of model customization
- Failure mode: Relying solely on prompt engineering or massive model updates creates high maintenance costs and model-specific technical debt
- Main idea: Effective adaptation requires a three-pillar approach: adaptive data, adaptive intelligence, and adaptive interfaces for feedback loops
- Practical takeaway: Implementing proportional compute allocation—routing simple tasks to small models and complex tasks to reasoning models—optimizes efficiency
