Inference Cache Intelligence: Predictive Query Optimization

LLM inference costs add up fast, but most applications have predictable patterns. This intelligent caching layer learns what queries are likely to come next and pre-computes answers during off-peak hours, slashing both costs and response times.

App Concept

  • Drop-in caching proxy that sits between your application and LLM APIs
  • ML-powered pattern recognition identifies frequently requested query variations
  • Semantic similarity matching returns cached results for near-duplicate queries
  • Predictive pre-computation runs anticipated queries during low-cost periods
  • Real-time cost dashboard shows savings vs direct API calls
  • Support for OpenAI, Anthropic, Cohere, and self-hosted models

Core Mechanism

  • One-line SDK integration redirects LLM calls through the intelligent cache
  • System learns usage patterns: time-of-day trends, seasonal variations, user cohort behaviors
  • Semantic embeddings cluster similar queries to maximize cache hit rates
  • Background jobs pre-compute high-probability queries when token prices are lowest
  • Automatic cache invalidation based on model version changes or data freshness requirements
  • Gamification: Daily cost savings leaderboard across all team members
  • Social proof: Share "We saved $X this month" achievements

Monetization Strategy

  • Usage-based pricing: 20% of cost savings generated (customers only pay when they save)
  • Flat tier option: $199/mo for up to 1M tokens, $999/mo for up to 10M tokens
  • Enterprise tier ($2,999/mo): Multi-region deployment, custom pre-computation rules, priority support
  • Free tier: 100K tokens/month with basic caching (no predictive features)
  • Revenue share with compute providers for off-peak usage optimization

Viral Growth Angle

  • Public ROI calculator showing potential savings based on current API usage
  • Case studies with impressive savings numbers: "How CompanyX cut LLM costs by 73%"
  • Integration showcases at AI engineering conferences
  • Developer advocates creating tutorials and benchmarks
  • Community-driven cache sharing for common use cases (with privacy controls)
  • Emotional shareability: Screenshots of cost savings dashboards going viral on Twitter/LinkedIn

Existing projects

  • GPTCache - Open-source semantic cache for LLM queries
  • Redis - General-purpose caching (not LLM-specific)
  • Helicone - LLM observability with basic caching features
  • Portkey - AI gateway with caching and routing
  • LangChain Cache - Basic in-memory/Redis caching
  • Martian - LLM router with cost optimization

Evaluation Criteria

  • Emotional Trigger: Limit risk - prevent budget overruns; be prescient about usage patterns to optimize proactively
  • Idea Quality: Rank: 7/10 - Moderate emotional intensity (cost concerns) + solid market potential (every LLM user wants lower costs)
  • Need Category: Foundational Needs (Level 1) - Budget for experimentation and sufficient compute resources at reasonable cost
  • Market Size: $800M+ market - every company using LLM APIs (200K+ organizations), $3K-$15K annual value based on usage
  • Build Complexity: Medium - requires semantic similarity matching, pattern recognition ML, multi-provider API integration, and distributed caching infrastructure
  • Time to MVP: 6-10 weeks with AI coding agents (basic semantic caching), 12-16 weeks without
  • Key Differentiator: Only caching platform combining ML-powered predictive pre-computation with semantic similarity matching and multi-provider support specifically optimized for LLM inference patterns
