Description
Rapidly refine your work and deploy with assurance. To ensure confident deployment, assess your prompts using a comprehensive evaluation toolkit that includes context recall, LLM as a judge, latency metrics, and additional tools. Let us take care of intelligent caching and sophisticated integrations to help you save both time and resources. Engage in swift iterations of your prompts within a collaborative environment that accommodates all leading providers, supports variables, offers automatic versioning, and more. Effortlessly create datasets from actual data utilizing Logs, upload your own as a CSV file, or collaboratively construct and modify within your Adaline workspace. Monitor usage, latency, and other important metrics to keep track of your LLMs' health and your prompts' effectiveness through our APIs. Regularly assess your completions in a live environment, observe how users interact with your prompts, and generate datasets by transmitting logs via our APIs. This is the unified platform designed for iterating, evaluating, and overseeing LLMs. If your performance declines in production, rolling back is straightforward, allowing you to review how your team evolved the prompt over time while maintaining high standards. Moreover, our platform encourages a seamless collaboration experience, which enhances overall productivity across teams.
