Prompt compression vs context optimization

Prompt compression often aims to encode or shorten text. Context optimization asks a different question: which source evidence is necessary for this task, and can it be safely omitted when it is not?

Safe fallback to original You control the model call Measure effective savings

Practical guidance

Compression can be useful

Generic compression is valuable where approximate meaning is acceptable and input shape is predictable.

Practical guidance

Evidence selection has a different safety contract

For policy, financial, legal, support and code contexts, preserve conditions, numbers, entities and links to the source. If the contract cannot be met, return the original.

Practical guidance

Choose by workload

Compare tools on effective token saving, evidence recall, answer quality, unsafe acceptance, recovery behavior and latency using your own representative workloads.
