What is Adaline?

Rapidly refine and deploy with assurance. To ensure a successful deployment, evaluate your prompts through various assessments such as context recall, the LLM-rubric serving as an evaluator, and latency metrics, among others. Our intelligent caching and complex implementations handle the technicalities, letting you concentrate on conserving both time and resources. Engage in a collaborative atmosphere that accommodates all major providers, diverse variables, and automatic version control, which facilitates quick iterations on your prompts. You can build datasets from real data via logs, upload your own data in CSV format, or work together to create and adjust datasets within your Adaline workspace. Keep track of your LLMs' health and the effectiveness of your prompts by monitoring usage, latency, and other important metrics through our APIs. Regularly evaluate your completions in real-time, observe user interactions with your prompts, and create datasets by sending logs through our APIs. This all-encompassing platform is tailored for the processes of iteration, assessment, and monitoring of LLMs. Furthermore, should you encounter any drop in performance during production, you can easily revert to earlier versions and analyze the evolution of your team's prompts. With these capabilities at your disposal, your iterative process will be significantly enhanced, resulting in a more streamlined development experience that fosters innovation.
