_**Arize AI + Phoenix OSS**_

Arize is an AI engineering platform focused on testing, evaluation and observability. It helps engineers develop, evaluate, and observe AI applications and agents. 

## Building AI Agents and Applications with Arize AI

Arize has both enterprise and open source projects to support this goal: 

* Arize AX and Enterprise: AI engineering platform spanning development to production, featuring an AI Copilot
* [Phoenix](https://github.com/Arize-ai/phoenix): open-source library for LLM evaluation, tracing, and prompt management
* [OpenInference](https://github.com/Arize-ai/openinference): an open-source instrumentation package to trace LLM applications across models and frameworks

## Arize AI and Hugging Face

Both Arize AI and Phoenix partner with Hugging Face to accelerate the reliable deployment of AI agents and systems. 

* Learn how to use Phoenix with the SmolagentsInstrumentor to [trace smolagents](https://docs.arize.com/phoenix/tracing/integrations-tracing/hfsmolagents) by Hugging Face 
* Learn how to [set up a Phoenix observability dashboard on Hugging Face Spaces](https://huggingface.co/learn/cookbook/en/phoenix_observability_on_hf_spaces) for LLM application tracing

## Helpful Tools and Learning Resources

Keep up-to-date with the latest frameworks, research and best practices in generative AI:
