Our Commentary ​

We appreciate Simon Willison's commitment to shipping 1.0 versions! This condense-json library is a clever solution to a specific problem: reducing redundancy in JSON, especially for verbose LLM outputs. It's a niche tool, but for those dealing with large volumes of structured data, especially from AI, this could be a real lifesaver for storage and transfer costs.
