Project Lifecycle

1. Prototype

Athina offers a user-friendly interface for prototyping, resembling a spreadsheet, that simplifies various tasks. It enables users to generate synthetic datasets for training and testing, allowing for the prototyping of powerful pipelines with dynamic columns in a spreadsheet-like UI. Additionally, Athina facilitates efficient testing, versioning, and deployment of prompts. Users can manage and version prompts seamlessly within their workflows. The tool also allows for the classification and extraction of data by creating dynamic columns in datasets. Editing and annotating datasets is made straightforward with its spreadsheet-like interface.

2. Experiment

Athina offers a wide array of tools for experimenting with your LLM application, enabling users to explore various aspects effectively. Users can experiment with different combinations of models and prompts, and test various models on the same trace. It allows for the re-running of prompts across multiple models and the regeneration of datasets using different models or prompts. Athina also facilitates the transformation of data using dynamic columns and enables users to compare prompts side-by-side. Additionally, it includes a diff view feature for comparing datasets, enhancing the analytical capabilities of the platform.

3. Evaluate

Athina can detect bad outputs and hallucinations, and prevent regressions. There is a library of 50+ evaluation metrics to test your pipeline, from answer similarity checks for your LLM to safety checks ensuring that the user has not entered Personally Identifiable Information (PII). All of these can be run either programmatically using their SDK or automatically through their SaaS platform.

Athina's evaluators extend their functionality beyond just assessing responses within the Retrieval-Augmented Generation (RAG) pipeline. These evaluators are designed to scrutinize the entire process, including the adequacy of the retrieved context. For example, if a user asks, "Which spaceship was first to land on the moon?" and the retrieved information is lacking, the evaluator will identify this gap. This mechanism ensures that any deficiencies in the context are flagged and corrected, leading to more accurate and reliable AI responses in future interactions.

Additionally, Athina enhances its platform with several advanced evaluation features aimed at optimizing performance and user experience. The cost management feature dynamically samples logs during LLM-powered evaluations to manage costs effectively, preventing excessive expenditure. For ongoing reliability, Athina incorporates continuous monitoring and alerting systems that keep track of LLM inferences, promptly notifying users of any anomalies or critical issues that may arise. Furthermore, teams have the flexibility to design and implement custom evaluators, using either an existing LLM or a custom function tailored to their specific requirements, enabling a highly personalized evaluation framework.

4. Monitor

Athina offers a comprehensive monitoring solution that tracks usage metrics over time, integrating seamlessly with any model or framework, including the most popular ones. It provides real-time monitoring of LLM performance and tracks costs and latency to optimize resource management. Users can configure alerts for critical events, measure accuracy over time to ensure consistent quality, and export logs for detailed analysis. Additionally, Athina supports GraphQL API access for advanced querying and enables enhanced data handling through search, filter, and sort functions. It also facilitates running experiments and inspecting complex traces, making it a versatile tool for managing and improving LLM applications.

5. Use Cases
