LLM Insight provides a centralized platform to track and manage the costs associated with large language models (LLMs) like OpenAI, Ollama, Anthropic, and Google. Users can organize costs by department or project, set cost limits, view visualizations, download invoices, and receive email notifications. The app features a logging system to track token usage and associated costs, and supports chargebacks at the department/project level for better cost management. API integration is available for businesses looking to integrate LLMs into their own projects with cost tracking.
