Anthropic Targets Enterprise Coding and Agent Workloads With Sonnet 4.5

Anthropic launched Claude Sonnet 4.5 on September 29, 2025, explicitly positioning the model for enterprise API customers building coding copilots and autonomous agent systems. The release signals a direct competitive push against OpenAI, Google DeepMind, and other frontier labs for high-value, high-volume production workloads. Anthropic has made Sonnet a deliberate market position since mid-2024, building developer familiarity through free consumer access before scaling to enterprise consumption.
