Claude Code Costs, Act III — The ecosystem of options for spending less

The article dives into the open-source solutions available for reducing the costs associated with large language models (LLMs). It highlights the different cost lines—cached input, uncached/written input, and output—that these solutions target. The key challenge is finding a method that cuts costs without sacrificing the model's prompt cache, which is crucial for efficiency. This guide underscores the importance of balancing cost-efficiency with maintaining model performance, which is increasingly relevant as LLMs become more prevalent and expensive to run.
