Providers

Connect to 62+ AI providers across OAuth subscriptions, free tiers, and pay-per-token APIs. Each provider takes seconds to set up.

A provider is an upstream AI service kRouter routes to. We support 62+ of them today across four tiers.

The four provider tiers

OAuth subscription

Sign in once with your existing paid subscription. kRouter manages refresh tokens, hands them back to upstream, and tracks per-account quota.

  • Claude Code (Pro/Max) — Opus 4.7, Sonnet 4.6, Haiku 4.5
  • OpenAI Codex (Plus/Pro) — GPT-5.5, 5.4, 5.3-codex
  • GitHub Copilot — multi-model with GPT, Claude, Gemini, Grok
  • Cursor IDE — Claude Opus Max, Sonnet Thinking, GPT-5.3
  • Antigravity — Gemini 3 Pro + Claude via Vertex
  • xAI (Grok) — OAuth or API key

Some OAuth providers (Claude Code, Codex, Antigravity, Copilot) use sessions not officially sanctioned for proxy use. We surface a risk badge in the dashboard.

Free tier (unlimited)

Genuinely free providers with no cap or very generous quota.

  • Kiro AI — free Claude 4.5 + GLM-5 + MiniMax via AWS Builder ID / Google / GitHub
  • OpenCode Free — no-auth passthrough, models auto-fetched
  • Gemini CLI — works inside Gemini CLI itself
  • Qoder — free unlimited coding tier

Free credits / metered

Free quota inside a paid platform. Drop in your API key, get hundreds of dollars worth of free credits before billing kicks in.

  • Vertex AI — $300 credits, 90 days for new GCP accounts
  • NVIDIA NIM — free for NVIDIA Developer Program members
  • Cloudflare Workers AI — free edge-runtime tier
  • BytePlus ModelArk — free credits, Seed 2.0 + Kimi K2
  • Gemini (direct API) — 15 RPM, 1M tokens/day free

Pay-per-token

Drop in your API key, pay per token. Use as cheap backup or primary.

OpenRouter, OpenAI, Anthropic, GLM, MiniMax, Kimi, DeepSeek, Groq, Mistral, Perplexity, Together AI, Fireworks, Cerebras, Cohere, SiliconFlow, Nebius, Chutes, Hyperbolic — and more.

Connecting a provider

  1. Open the dashboard at http://localhost:20128/dashboard
  2. Go to Providers
  3. Pick a tile — kRouter knows the right auth flow per provider
  4. For OAuth: a browser tab opens, sign in, done
  5. For API key: paste the key, hit Save
  6. For free passthroughs: just click Connect

After connecting, hit Test connection so kRouter validates the credentials and pulls the model catalogue.

Provider IDs and aliases

Every provider has a short alias used in model IDs. When you pick a model, the format is always <alias>/<model-id>. For example:

ProviderAliasExample model
Claude Codecccc/claude-opus-4-7
Antigravityagag/gemini-pro-agent
Kiro AIkrkr/claude-sonnet-4.5
OpenRouteropenrouteropenrouter/anthropic/claude-opus-4
GLMglmglm/glm-5.1

See the Providers page for the full list with example models.

Multi-account routing

You can connect multiple accounts of the same provider. kRouter rotates between them with round-robin, priority, or P2C strategies. Set the strategy per-provider in the dashboard.

This is how single users effectively double or triple their Claude Code / Codex quota without breaking rules — each account is genuinely yours, kRouter just picks which one serves each request.
