Could you build this?
Partial The API endpoint and SDKs are straightforward to build, but effective context compression that preserves semantic nuance while dropping 80-90% of tokens requires custom NLP research or fine-tuned selector models.
What it would actually take: The service needs an API gateway (Go/FastAPI) and language SDKs, backed by high-throughput model inference. The challenging technical core is the compression algorithm—either utilizing attention score extraction from open-weight models, trained small ranker/extractive models (e.g., fine-tuned cross-encoders), or LLMLingua-style information-entropy token masking. Developing this requires expertise in embedding spaces, KV-cache manipulation, and token-level relevance estimation to ensure downstream task accuracy does not degrade.
