OpenAI’s GPT models offer broad capability across text, code, analysis, and multimodal inputs. GenosOS uses GPT-5.4 as the default model and automatically escalates to o3 when a task requires deep, multi-step reasoning.
Models
| Tier | Model | When it’s used |
|---|
| Default | GPT-5.4 | All standard requests |
| Boost | o3 | Complex reasoning tasks, important requests, explicit urgency |
Model switching is automatic. When you express importance or urgency, the boost tool activates o3 mid-conversation without interrupting the flow.
Getting an API key
Go to the OpenAI Platform
Navigate to API Keys
In the left sidebar, click API Keys (under your account or project settings).
Create a new secret key
Click Create new secret key, give it a name (e.g. GenosOS), and copy the key immediately — it will not be shown again.
Key format: OpenAI API keys start with sk-
Copy the key before closing the dialog. OpenAI does not display the full key again after creation.
Configuring GenosOS to use OpenAI
On first run
The first-run wizard asks which provider you want to use. Select OpenAI and paste your sk- key when prompted. GenosOS validates it and stores it encrypted in the vault.
Switching from another provider
Tell the assistant:
"Use OpenAI"
"Switch to OpenAI"
"Switch me to GPT"
If GenosOS does not already have your key on file, it will ask you to paste it.
Setting a specific key
"Set my OpenAI API key to sk-proj-..."
Once stored, your key is encrypted with AES-256-GCM in the GenosOS vault. You can switch between providers and back without re-entering keys.
o3 boost
o3 is OpenAI’s most capable reasoning model. GenosOS reserves it for situations where standard GPT-5.4 would benefit from deeper deliberation — planning, logic puzzles, research synthesis, architectural decisions.
Examples that trigger o3 boost:
"This is really important — I need this to be exactly right"
"Give me your best analysis of this"
"I need to make a critical decision here"
The boost activates automatically. You do not need to name o3 directly.
