LLMConfig class

Unified configuration class for all LLM providers

This class provides a common configuration interface while allowing provider-specific extensions through the extensions map.

Constructors

LLMConfig({String? apiKey, required String baseUrl, required String model, int? maxTokens, double? temperature, String? systemPrompt, Duration? timeout, double? topP, int? topK, List<Tool>? tools, ToolChoice? toolChoice, List<String>? stopSequences, String? user, ServiceTier? serviceTier, Map<String, dynamic> extensions = const {}})

const

LLMConfig.fromJson(Map<String, dynamic> json)

Create from JSON representation
