OpenRouter

OpenRouter is the largest multi-provider LLM gateway, one API key and one prepaid credit balance across hundreds of models from dozens of providers, with automatic routing and fallback. Facts below verified as of 2026-09-26.

What it is
#

A marketplace gateway founded in early 2023 by Alex Atallah (OpenSea co-founder). Provider token prices pass through unchanged; you fund prepaid credits and OpenRouter takes a fee on the purchase, not on inference. Routing variants (:nitro for speed, :floor for price, :exacto for tool-calling quality, :free and :batch) change how requests are placed, and BYOK keeps your own provider keys behind OpenRouter’s routing, analytics, and fallbacks.

Status
#

The scale is venture-grade: $113M Series B led by Alphabet’s CapitalG at about $1.3B post-money in May 2026, with 8M users and roughly 100 trillion tokens per month. Annualized inference spend through the platform grew from $10M (October 2024) to over $100M (May 2025), per a tracked pricing blueprint. On 2026-08-19 OpenRouter announced it is joining Stripe, with closing expected within weeks of the announcement; the post commits to the same product, name, roadmap, and provider-neutral routing, and states the platform now processes 10+ trillion tokens per day across 400+ models for more than 10 million developers. The pricing page was rebuilt on 2026-09-20 into four tiers (Free, Standard, Business, Enterprise), and the pricing page itself renders client-side, so my fetch returned navigation only.

Strengths
#

Passthrough pricing is real: verified spot checks (Claude Opus 5 at $5/$25) match provider list prices.
One key, one balance, automatic provider fallback, per-model price/latency comparison, and a fee structure published in full.
Free tier is a genuine on-ramp: 25+ free models, 1,000 requests/day after a one-time $10 credit purchase.
BYOK is free through $25,000/month of list-price inference, which covers most teams entirely.
The Business tier makes EU-only or US-only routing self-serve instead of an Enterprise contract.

Cautions
#

The 5.5% credit fee with a $0.80 minimum punishes small top-ups: a $5 purchase costs 16% in fees.
BYOK’s free allowance is metered at OpenRouter list price, not your negotiated rate, so discounts do not slow the meter.
Paid-tier rate limits are passthrough from providers, and 429s arrive without queueing or backoff; your client owns retries.
No public SLA below Enterprise.
Routing can silently move you to a different provider, and a provider price change flows straight to your bill.
Credits may expire after one year per the terms.

Pricing
#

Free: $0, 25+ free models, 20 requests/minute, 50 requests/day (1,000/day with $10 lifetime credits), workspace limit 5. Standard: 5.5% fee per credit purchase, $0.80 minimum, crypto 5.0% flat, no subscription, workspace limit 5. Business: 8% fee, inference locked to EU or US providers with no cross-region fallback, workspace limit 1,000 (launched 2026-09-07). Enterprise: custom, volume commitments, SSO/SAML, contractual SLAs, $200,000/month free BYOK allowance. BYOK: 5% of equivalent cost above the free allowance, as of 2026-09-26.

Compared to

OpenCode Go (../opencode-go/index.md) is a $10 subscription for open coding models with hard caps; choose OpenRouter when your usage is spiky or you need frontier models. OpenCode Zen (../opencode-zen/index.md) is the curated coding gateway, usually pricier per token on open models; choose Zen when benchmarked endpoints and free stealth models matter more than unit cost. Direct provider accounts are cheapest for one dominant model at scale, at the cost of N billing relationships and no cross-provider fallback.

Bottom line
#

Recommended for multi-model teams and tinkerers who value breadth, fallback, and one bill. Not for single-provider, high-volume workloads with negotiated rates, where the fee is pure overhead. My disagreeable claim: I would pay the 5.5% rather than run the same multi-provider setup myself, because the fee buys uptime pooling, not just convenience.
