Mid-sized enterprises transition AI into reliable production operation not through spectacular applications, but through clear processes, human decision-making authority, and pragmatic data protection practices – without large IT departments.
The performance gap between local open-source models and cloud-based frontier models is shrinking to four to eight months, while local systems simultaneously regain control over data and infrastructure.
Sonnet 5 offers Opus 4.8-like performance at theoretically the same price as Sonnet 4.6, but a new tokenizer increases practical operating costs by approximately 30 percent.
