Claude Models and Efforts | Bondar Academy
Course: Claude Code for Playwright
Module: Core Concepts
Instructor: Artem Bondar
Lesson Summary
This lesson discusses the configuration of models and their respective efforts within the Cloud system. There are three models available: Haiku : The cheapest model with the lowest reasoning capabilities. Sonnet : A balanced model offering moderate reasoning. Opus : The most expensive and capable model, designed for complex tasks. The choice of model is crucial, especially for users on the ProPlan , which has limited session capacities. Using the Opus model can quickly exhaust session limits, making it beneficial to switch to Sonnet or Haiku for less demanding tasks. Model Configuration To change the model, use the following command: /model_name Available options include: Sonnet (default, regular, one million context window) Haiku (fastest) Effort Configuration Each model has adjustable effort settings that determine how deeply the model can explore relevant information: Opus : High, Extra High (default), Max Sonnet : Medium, High, Max Adjusting the effort can help save on tokens and is particularly important for ProPlan users. Experimenting with different models is recommended to find the most efficient option for specific tasks, such as writing Playwright tests . In summary, understanding model and effort configurations can enhance session management and optimize performance based on task complexity.
