Flow AI vs Martian

Martian is a model router that predicts, per prompt, which model will perform best and routes accordingly — 'model mapping' aimed at beating any single model on quality/cost.

What Martian optimizes for

Predictive per-prompt model selection from prompt features.

• Prediction-based routing — no need to try a model to pick one
• Strong research pedigree on model-capability mapping
• Simple drop-in router API

What Flow AI does differently

• Flow routes on measured outcomes, not predictions: it tracks whether each model actually completed your agents' tasks (tool-use + completion signals) and re-ranks continuously
• The cascade makes prediction errors cheap: serve the cheapest capable model, judge, escalate only on failure — failed cheap attempts aren't charged
• Marketplace supply (flat-rate subscriptions, community capacity, verified free models) pushes clearing prices below list — routing and sourcing in one layer
• Pass-through + 2.5% billing with per-response cost traces

How to choose

Choose Martian for prediction-first routing research workloads. Choose Flow AI when you run agents in production and want routing grounded in whether your own tasks actually completed — with supply-side savings included.
