OpenAI

The direct provider for OpenAI models. The app sends each request straight to OpenAI and streams the reply; tools execute locally.

Construct it

let agent = try runtime.makeAgent(
    provider: .openAI(apiKey: key, model: "gpt-4o"),
    role: AgentRole(staticPersona: "You are a precise video-editing assistant.")
)

Hold the provider directly when you need it:

let provider = OpenAIProvider(apiKey: key, model: "gpt-4o")

model defaults to gpt-4o and is a plain string — any model OpenAI offers works without a framework update. baseURL: points the provider at an OpenAI-compatible proxy.

What it supports

Structured turns (get data, not prose) ride OpenAI's strict JSON-schema response format. The schema root must be an object — a non-object root is rejected before any request is sent.

The full flag-by-flag table lives in the capability matrix.

Keep the key out of shipped apps

.openAI(apiKey:) sends the key from the device — fine for prototypes, extractable from any shipped binary. For production, name an agent profile instead of a key.
