Anthropic released Claude 3 Opus on March 4th, 2024, with enterprise inference as the target. Ten days later, I had my own client calling the API.

I used the same approach I built for OpenAI last year — hitting a REST endpoint. Format the message, set the headers, parse the response. Twenty minutes of work and I had Claude Opus in my pocket.

Why build a client when you can just use claude.ai? Control. I decide the system prompt. I decide what context gets sent. I can switch between Opus and Sonnet depending on the task. No browser tabs, no subscription UI — just a direct line to the model.

Most people interact with AI through interfaces built by someone else. I’d rather build my own. It’s not about the technology. It’s about understanding how these systems actually work, how to maintain enterprise grade security, not just what they produce.
