Let the model call your functions
await RunAnywhere.llm.tools.register(weatherTool) { args in
let city = args["city"]?.stringValue ?? ""
return ["tempC": .init(doubleValue: try await fetchTemp(for: city))]
}
let result = try await RunAnywhere.llm.generate(
prompt: "What is the weather in Lisbon?"
)
func register(_ tool: ToolDefinition, executor: @escaping ToolExecutor) async
func unregister(name: String) async
func list() async -> [ToolDefinition]
func clear() async
let weatherTool = ToolDefinition(
name: "get_weather",
description: "Get the current temperature for a city",
parameters: [
ToolParameter(
name: "city",
type: .string,
description: "City name",
required: true
)
]
)
ToolParameter takes name, type, description, required (default true), and
enumValues (default []).
LlmOptions:
| Field | Default | Meaning |
|---|---|---|
tools | [] | Tools for this call only |
toolChoice | .auto | Whether the model may call a tool |
maxToolCalls | 5 | Cap on calls in one exchange |
autoExecute | true | Run executors automatically |
let result = try await RunAnywhere.llm.generate(
prompt: "Weather in Lisbon and Porto?",
options: LlmOptions(toolChoice: .auto, maxToolCalls: 3)
)
tools.register are offered to every generation. Tools passed in
options.tools apply to that call alone.
await RunAnywhere.llm.tools.unregister(name: "get_weather")
await RunAnywhere.llm.tools.clear()
let registered = await RunAnywhere.llm.tools.list()
await RunAnywhere.llm.tools.register(
RunAnywhere.webSearchToolDefinition,
executor: RunAnywhere.executor
)
