●●●BangerZero to OneSolve My Problem

Cuts token costs 70% with receipts proving no accuracy drop on hard evals.

Strengths
  • Receipts feature provides verifiable spans showing exactly what text was retained
  • Zero accuracy drop on AIME math and GPQA science benchmarks at 70% compression
  • Works as a drop-in proxy before any model provider without changing existing code
Weaknesses
  • Another pre-processing hop adds latency before the actual model inference starts
  • Black-box compression logic makes it hard to audit why specific content was removed
