GenosOS ships with three hand-picked providers. Every provider on the list has been verified to work with the full tool-calling pipeline, smart model routing, and conversational configuration. No half-supported models, no “experimental” flags.

​
No configuration paralysis

Most AI tools ask you to choose from dozens of providers, each with its own setup screen, credential format, and model naming convention. GenosOS does not. Pick one provider, paste your API key, and you are done. The assistant handles everything else. 
First run:
  → "Which provider would you like to use? Anthropic, OpenAI, or Gemini"
  → "Paste your API key"
  → Done. Browser opens. Start talking.

Every provider uses a two-tier model pair:
  • Default model — used for everyday tasks. Fast and cost-efficient.
  • Boost model — reserved for complex or high-stakes tasks. Activated automatically.

​
Smart model routing

You never have to switch models manually. GenosOS watches for signals in your language and auto-escalates to the boost model mid-conversation when it detects importance, urgency, or a request for excellence. The boost tool activates the best available model for the current provider the moment it’s needed — then the conversation continues without interruption. Examples that trigger boost:
  • “This is really important, I need to get it right”
  • “Make sure this is perfect”
  • “I need your best work on this”
  • “This is urgent”
Boost escalation is transparent. The assistant does not announce the model switch — it simply uses the more capable model for that response and continues.

​
Configuring your provider

​
First-run wizard

On first run, GenosOS walks you through provider selection interactively:
1

Choose a provider

The wizard presents three options: Anthropic, OpenAI, or Gemini.
2

Paste your API key

Enter the key you created on the provider’s dashboard. GenosOS validates it immediately.
3

Done

The browser opens. Your key is stored encrypted in the vault. You will not be asked again.

​
Switching providers conversationally

You can change your active provider at any time by telling the assistant: 
"Switch to Anthropic"
"Use OpenAI"
"Switch me over to Gemini"
"Set my provider to Anthropic"
The assistant will ask for your API key if it does not already have one on file for that provider.
You can store keys for multiple providers. GenosOS encrypts all credentials in the vault — switching between providers is instant once each key is stored.
