The Problem

Developers pay $15-75/M tokens for Claude Opus on every message, even "what time is it?" There's no automatic way to route simple prompts to cheap models and complex ones to capable models. Companies overspend on API costs by sending simple categorization tasks to expensive frontier models.

The Solution

Intelligent LLM router with a 14-dimension weighted classifier that scores every prompt in <1ms with zero API calls. Routes to the cheapest model that can handle the task.

Key Innovation

Local classification (no API call for routing) + fallback chains + 60-80% cost savings with imperceptible latency overhead.

Intelligent Routing Tiers

The ModelMesh router classifies every incoming prompt and directs it to the most appropriate model based on our four-tier classification system.

Tier	Score	Model	Cost/M Tokens	Use Case
SIMPLE	<0.33	Gemini Flash	$0.10	Quick Q&A
MEDIUM	0.33-0.425	Sonnet	$3.00	Code gen
COMPLEX	0.425-0.58	Opus	$15.00	Architecture
REASONING	≥0.58	Opus	$15.00	Math proofs
