isKnownReasoningModel static method

bool isKnownReasoningModel(String model)

Check if the model is known to support reasoning (broader check) This is a hint for UI behavior, but actual reasoning detection should be based on response content, not model name

Implementation

static bool isKnownReasoningModel(String model) {
  final id = model.toLowerCase();

  // Restrict OpenAI reasoning detection to known OpenAI-style ids
  final isOpenAIModel = id.startsWith('gpt-') ||
      id.startsWith('o1') ||
      id.startsWith('o3') ||
      id.startsWith('o4');

  final isOpenAIReasoning = isOpenAIModel && isOpenAIReasoningModel(model);

  return isOpenAIReasoning ||
      model == 'deepseek-reasoner' ||
      model == 'deepseek-r1' ||
      model.contains('claude-3.7-sonnet') ||
      model.contains('claude-opus-4') ||
      model.contains('claude-sonnet-4') ||
      model.contains('qwen') && model.contains('reasoning') ||
      id.contains('reasoning') ||
      id.contains('thinking');
