Connect the systems that carry your operating context.
Nexus brings models, communication tools, publishing systems, project boards, and infrastructure signals into one governed workflow so intent can become accountable execution.
Model choice stays inside the operating surface.
OpenAI
Direct API access for GPT and reasoning model families.
Anthropic
Direct Claude access with API key and supported device login paths.
Gemini
Google-hosted Gemini access through direct configuration or Google auth.
GitHub Copilot
Use Copilot-backed model access with account-based authentication.
OpenRouter
Broad multi-model access across OpenAI, Anthropic, Google, and open-weight catalogs.
Authentication is matched to the provider instead of forced into one workflow.
Nexus supports API keys, OAuth, and device login flows depending on what each provider actually exposes. That keeps setup practical and reduces auth drift between providers.
Bring Your Own Key
Connect direct provider keys when you want Nexus to use your existing quota and billing relationship.
OAuth Connections
Use account-based authorization where the provider supports a browser-driven consent flow.
Device Login Flows
Authenticate CLI-style providers with a verification code flow when direct key entry is not the right path.
60+ models available
The runtime catalog spans direct provider models and router-backed catalogs so teams can choose the right reasoning path without separating it from business context.
Keep provider choice flexible without changing the operating workflow.
Route reasoning through the right model while preserving the same business context.
Keep auth methods aligned to what each provider actually supports instead of forcing a single setup path.
Make model choice part of governed execution instead of a separate technical workflow.
