Can I still use whylogs and langkit?

Yes. Both whylogs and langkit are actively maintained open-source projects on GitHub and can be used independently of the WhyLabs platform.

What is the best replacement for the WhyLabs dashboard?

There is no direct drop-in replacement. You will need to self-host the open-sourced platform or integrate whylogs profiles with your own monitoring stack.

How do I migrate my existing WhyLabs setup to the OSS version?

Migration requires deploying the whylabs-oss platform, reconfiguring your data ingestion to point to your instance, and ensuring your whylogs writers are compatible with the self-hosted API.

What underlying technology does whylogs use for data profiling?

whylogs creates lightweight statistical profiles (summaries) using techniques like KLL sketches for quantiles and frequent item algorithms, preserving privacy by not storing raw data.

New course with WhyLabs and DeepLearning.AI: Quality and Safety for LLM Applications

Built in collaboration with DeepLearning.AI, the 'Quality and Safety for LLM Applications' short course is designed to help you create useful metrics to monitor your LLM systems for safety and quality. Upon completing this course, you’ll be able to: - Identify hallucinations with methods like SelfCheckGPT - Detect jailbreaks (prompts that attempt to manipulate LLM responses) using sentiment analysis and implicit toxicity detection models. - Identify data leakage using entity recognition and vector similarity analysis. - Build your own monitoring system to evaluate app safety and security over time.
