An OpenRouter Alternative With Flat Pricing and No Top-Up Fees
Same one-key convenience, simpler bill
OpenRouter popularized the idea of one API key for many models, and it does that well. But its billing runs on prepaid credits: every credit-card top-up carries a 5.5% platform fee with a $0.80 minimum, which makes small top-ups effectively cost 8-16% extra. Riven takes the same one-key idea and removes the credit layer entirely: a flat $3 per million tokens, metered after use, billed for exactly what you consumed. No balance to manage, no top-up fee, no expiring credits.
Flat $3 per million tokens across every model
On OpenRouter you pay each provider's list price, which means output tokens on frontier models can run $15-75 per million and your costs swing with every routing decision. Riven prices every model on the pay-as-you-go plan at the same flat $3 per million tokens. That predictability matters for agent workloads and batch jobs, where token volume is high and per-model price variance is the difference between a budget and a surprise.
20+ frontier models, OpenAI-compatible
One Riven key unlocks 20+ frontier models, including GPT-5.6, Claude, Gemini, GLM, and Kimi, from a single OpenAI-compatible endpoint. OpenRouter lists more models overall; Riven curates the set that covers real production workloads and keeps them all under one flat price. If your integration already speaks the OpenAI request format, switching is a base-URL and key change.
A full product, not just a router
OpenRouter is an API layer. Riven's API shares an account with a complete product suite: grounded chat with citations, coding and agent surfaces, and business tooling. Teams that want both an API for their applications and a workspace for their people get one vendor, one bill, and one set of keys.
When self-hosting matters
OpenRouter is cloud-only. For teams with strict data-residency, compliance, or latency requirements, Riven offers self-hosted, single-tenant deployments. Self-hosted, single-tenant AI for enterprises that demand control, compliance, and performance. Your infrastructure or ours.
