Reduce LLM API bills: prompt compaction, model-switching, caching

Enterprises overspend on LLM API usage because prompts are verbose and calls are unoptimized. A middleware that compacts prompts, routes to cost-appropriate models, and semantic-caches responses can cut bills ~50–80%.

Key Pain Points

Provider changes -- API pricing or tokenization changes from major providers can rapidly change economics and require frequent adaptation.
Low switching costs -- middleware approaches are easy to copy; differentiation must come from data and enterprise integrations.
Privacy/regulation -- enterprises with strict data controls may restrict sharing telemetry needed to build cross-customer efficiency models.
