Anthropic’s Claude models are known for precise reasoning, deep analysis, and reliable code generation. GenosOS uses Claude Sonnet 4.6 as the default model and automatically escalates to Claude Opus 4.6 for tasks that demand higher capability.

Models

TierModelWhen it’s used
DefaultClaude Sonnet 4.6All standard requests
BoostClaude Opus 4.6Complex tasks, important requests, explicit urgency
You do not switch models manually. When you express importance, urgency, or ask for your best work, the boost tool activates Claude Opus 4.6 automatically mid-conversation.

​
Getting an API key

1

Go to Anthropic Console

Open console.anthropic.com and sign in or create an account.
2

Navigate to API Keys

In the left sidebar, click API Keys.
3

Create a new key

Click Create Key, give it a name (e.g. GenosOS), and copy the key immediately — it will not be shown again.
Key format: Anthropic API keys start with sk-ant- 
sk-ant-api03-...
Copy the key before closing the dialog. Anthropic does not display the full key again after creation.

​
Configuring GenosOS to use Anthropic

​
On first run

The first-run wizard asks which provider you want to use. Select Anthropic and paste your sk-ant- key when prompted. GenosOS validates it and stores it encrypted in the vault.

​
Switching from another provider

Tell the assistant: 
"Use Anthropic"
"Switch to Anthropic"
"Set my Anthropic key"
If GenosOS does not already have your key on file, it will ask you to paste it.

​
Setting a specific key

"Set my Anthropic API key to sk-ant-..."
Once stored, your key is encrypted with AES-256-GCM in the GenosOS vault. You can switch providers and switch back without re-entering the key.

​
Claude’s strengths

Claude performs particularly well on tasks that require:
  • Reasoning and analysis — breaking down complex problems, weighing tradeoffs, structured thinking
  • Coding — writing, reviewing, debugging, and explaining code across most languages
  • Long-form writing — precise prose, technical documentation, summarization
  • Instruction following — Claude reliably follows detailed, multi-part instructions
These characteristics make Anthropic a strong default choice for most GenosOS users.
