As AI agents grow, vendors carve out decision-making as a separate model layer

Leading AI vendors like Cloudflare and AWS are introducing specialized decision-making models as a distinct layer in AI agent architectures to reduce inference costs and latency by handling routine decisions locally or separately from larger reasoning models. However, this approach risks increasing architectural complexity and operational overhead due to AI-stack sprawl, decision schema management, and the need for continuous calibration across multiple models.
