No intelligent way to automatically select the best LLM for each task

Users struggle to manually choose the optimal LLM based on task type, latency, cost, and performance; need an automated router for better results.

Automatic LLM routing layer that picks the right model for each task based on cost, speed, and quality tradeoffs.

The pain

Teams using multiple LLMs (GPT-4, Claude, Llama, etc.) waste time deciding which model to use per task. They either overspend by defaulting to expensive models or underspend and get poor results. No standard way exists to measure and compare model performance on their specific workloads.

The gap

LLM providers compete on model quality but don't solve the selection problem. Existing solutions are either too simple (rule-based routing) or too rigid (locked into one provider). The market lacks a vendor-neutral router that learns from actual task performance data.

Build angle

Start by building a router that tracks latency, cost, and output quality across models for a specific customer's tasks. Use their historical data to train a simple decision tree or classifier that routes new requests. Charge per API call routed or as a percentage of LLM spend saved. Focus on teams already using 3+ models.

Strengths

  • Real, measurable pain point for teams managing multiple LLM subscriptions
  • Defensible moat through proprietary performance data and routing models
  • Clear unit economics: percentage of LLM spend or per-call fees
  • Works across all LLM providers (vendor-neutral positioning)
  • Low switching costs once integrated into customer workflows

Risks

  • LLM providers (OpenAI, Anthropic) may build this feature natively into their platforms
  • Requires deep integration with customer systems to collect performance data; adoption friction is high
  • Market may be too small initially, only teams using 3+ models at scale care enough to pay
  • Routing logic becomes commoditized quickly once the concept proves out
  • Latency overhead of the routing layer itself could negate cost savings
  • Difficult to prove ROI without 6+ months of customer data
