Providers & Authentication
Connect hundreds of models across ~40 providers, and sign in with what you already use.
Sypha is model-agnostic — connect hundreds of models across ~40 providers with no lock-in, and sign in however you prefer.
Sign-in options
Sypha account (SSO)
Browser sign-in via Keycloak SSO. Unlocks the Sypha Gateway (managed models + Auto mode, which picks the best model per request).
Bring your own subscription
Sign in with what you already pay for:
- Claude Pro/Max (browser OAuth — usage meters shown in the sidebar)
- ChatGPT (Codex)
- GitHub Copilot
Bring your own key (BYOK)
Use any provider's API key directly — OpenAI, Anthropic, Google Gemini/Vertex, Amazon Bedrock, Groq, Mistral, DeepSeek, xAI, OpenRouter, and more.
Local models (no account)
Run Ollama or LM Studio locally — no account needed, and your code never leaves your machine. Perfect for sensitive or air-gapped projects.
Connecting a provider
Run /connect (or /models) to pick a provider and model. You can also point Sypha at any OpenAI-compatible custom endpoint.
On a Teams plan, the list of providers you can connect is governed by your admin — see Enterprise Access Control.
Security
Local models never send your code anywhere. For cloud providers, traffic is sent over HTTPS. Teams get dashboard-enforced Access Control over which providers members may use.
