Decision brief

Large Action Model (LaVague) framework supports developing AI web agents using customizable Large Language Models (LLMs), offering tracking of token usage for cost estimation purposes.

Good fit when

  • When you need a flexible framework that allows customization of LLMs, particularly if your primary model is OpenAI's `gpt4-o` or similar models.
  • If your project involves interacting with various websites requiring different levels of LLM complexity and you want precise cost estimation for running your agents.

Avoid when

  • Avoid using LaVague if you are working on projects that do not involve AI web agent development, as the framework is specifically designed around this use-case.
  • Do not opt for LaVague if you require a non-Python environment for your development since the framework is Python-based.
Pricing:
freemium - Free to use with customizable LLMs; actual costs depend on the specific LLM used and operational complexity.
Requirements:
Min 2 GB RAM; Requires Python for development.

💰 How much does it cost to run an agent?

LaVague uses LLMs, (by default OpenAI's gpt4-o but this is completely customizable), under the hood.

The cost of these LLM calls depends on:

  • the models chosen to run a given agent
  • the complexity of the objective
  • the website you're interacting with.

Please see our dedicated documentation on token counting and cost estimations to learn how you can track all tokens and estimate costs for running your agents.
