CheapGPT API Router
A usage-priced AI API that automatically picks the cheapest capable model for each prompt — small product builders pay cents instead of dollars per thousand tokens, with a dashboard showing which model handled what.
Indie SaaS founders and small product teams integrating AI features
- Automatic model routing per request based on capability requirements you define
- Cost dashboard showing per-feature spend and which model served each call
- Fallback chain if a cheap model fails quality checks
- Drop-in OpenAI-compatible API so existing code works with one URL change
Wafer just demonstrated frontier-model inference at 2x lower cost on AMD — small builders paying full Blackwell prices today will see major margin gains the moment cheaper capacity becomes easy to tap.
Strong, growing pain point: enterprise LLM API spend hit ~$8.4B in 2025 and '40-70% savings via routing' is the universal pitch across at least a dozen guides and vendor articles, with indie teams actively searching for OpenRouter alternatives.LLM Gateways & Model Routing: Cut AI Costs 2026 ↗7 Best OpenRouter Alternatives in 2026: Pricing & Migration ↗
Extraordinarily crowded: OpenRouter, LiteLLM, Portkey, Cloudflare AI Gateway, Helicone, Martian, Kong, Together AI, Fireworks AI, Eden AI, ZenMux, Vercel AI Gateway all already offer cheap-model auto-routing — OpenRouter literally already routes to cheapest capable model per request, and there are dedicated '16 alternatives' comparison posts.OpenRouter vs LiteLLM vs Portkey: Best LLM Gateway in 2026 ↗16 Best OpenRouter Alternatives for Private, Production AI (2026) ↗
Margins are structurally razor-thin because the value prop is selling the cheapest commodity available; OpenRouter and others already compete on tiny markups, and the target customer (indie, cost-sensitive) is the least willing to pay premium — pricing pressure is intense across the category.OpenRouter Alternatives for Lower AI API Cost ↗LLM Gateways & Model Routing: Cut AI Costs 2026 ↗
Durable as long as heterogeneous pricing across providers persists, but at risk of commoditization — frontier labs (OpenAI, Anthropic) are adding their own cascade/routing features, OpenRouter already does auto-routing, and model prices keep falling which compresses the savings spread this product monetizes.LLM Gateways & Model Routing: Cut AI Costs 2026 ↗
Technically trivial to build: LiteLLM is open source, dozens of gateways have been built by small teams, and the dashboard/model-selection UX is well-understood — the hard part is differentiation, not engineering.LiteLLM vs OpenRouter vs Portkey (2026) | AI Workflow Lab ↗
