Enum Class TaskType

java.lang.Object
java.lang.Enum<TaskType>
com.tnsai.llm.routing.TaskType
All Implemented Interfaces:
Serializable, Comparable<TaskType>, Constable
public enum TaskType extends Enum<TaskType>
Defines task types for intelligent model routing.

TaskType enables task-based model selection, where different LLM models are automatically selected based on what they're best at. For example:

  • Coding tasks → Models optimized for code (e.g., Claude Sonnet, GPT-4o)
  • Creative tasks → Models good at creative writing
  • Math tasks → Models with strong reasoning (e.g., o1, Gemini)
  • Fast tasks → Quick, cheap models (e.g., GPT-4o-mini, Groq)

Usage with TaskBasedRouter


 TaskBasedRouter router = TaskBasedRouter.builder()
     .forTask(TaskType.CODING, new AnthropicClient("claude-sonnet-4"))
     .forTask(TaskType.CREATIVE, new OpenAIClient("gpt-4o"))
     .forTask(TaskType.MATH, new OpenAIClient("o1-preview"))
     .forTask(TaskType.FAST, new GroqClient("llama-3.3-70b"))
     .defaultClient(new OpenAIClient("gpt-4o-mini"))
     .build();

 // Auto-classification
 router.chat("Write a Python function to sort a list");  // → CODING → Claude
 router.chat("Write a poem about autumn");               // → CREATIVE → GPT-4o
 router.chat("Solve: 2x + 5 = 15");                      // → MATH → o1

      Checks if the given text contains keywords for this task type.
      Parameters:
      text - The text to check
      Returns:
      true if any keyword matches

    • matchScore

      public int matchScore(String text)
      Calculates a match score for the given text.
      Parameters:
      text - The text to score
