The Anthropic API gives you a language model. Runcept gives you a complete AI agent. When to use each for developer workflows.
Calling Anthropic's API directly gives you the most control and the lowest per-token cost, but you write the system prompt, handle output parsing, and maintain that logic as models and your requirements change. Runcept trades some of that control for a finished agent — someone has already written and tested the prompt and schema for the specific task you need.
Choose the direct API when you need full control over the prompt, are optimizing hard for token cost at scale, or the task is specific enough that no existing agent fits it well.
Choose Runcept when you want a working result today without owning prompt maintenance — especially for common tasks (analysis, generation, research) where someone has likely already built and refined the agent.
