Provides configurable thinking budgets for LLM reasoning: * Token budgets for extended thinking * Time budgets for reasoning * Adaptive budget allocation * Budget tracking and reporting # Example ```ignore theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}} use praisonai::thinking::{ThinkingBudget, BudgetLevel, ThinkingTracker}; // Create a thinking budget let budget = ThinkingBudget::high(); // Or with custom settings let budget = ThinkingBudget::new() .max_tokens(16000) .adaptive(true) .build(); // Track usage let mut tracker = ThinkingTracker::new(); let usage = tracker.start_session(8000, None, 0.5); ``` ## Import ```rust theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}} use praisonai::thinking::*; ``` ## Classes Budget constraints for extended thinking. Controls how much thinking/reasoning the LLM can do before producing a response. Builder for ThinkingBudget. Configuration for thinking behavior. Usage statistics for a single thinking session. Tracks thinking usage across multiple sessions. Provides aggregate statistics and reporting. Predefined budget levels for thinking. *** ## Related Documentation
