About
Antaeus is a semantic policy engine for developers who need to evaluate human-written rules about language, context, intent, or exceptions. Its open-source Go core and command-line interface load YAML or JSON policy artifacts, validate them against versioned schemas, and run named regression cases. The evaluator returns explicit allow, review, deny, or failure outcomes with policy identity and decision evidence, leaving authentication, authorization, and consequential actions to the application. Developers can run a deterministic, credential-free local workflow or use the experimental hosted dashboard and API to manage policies and evaluate inputs. An experimental OpenAI evaluator is also available. Antaeus is an early-stage project; hosted service capacity is shared and has no production SLA.

About
Phoenix is an open-source observability library designed for experimentation, evaluation, and troubleshooting. It allows AI engineers and data scientists to quickly visualize their data, evaluate performance, track down issues, and export data to improve. Phoenix is built by Arize AI, the company behind the industry-leading AI observability platform, and a set of core contributors. Phoenix works with OpenTelemetry and OpenInference instrumentation. The main Phoenix package is arize-phoenix. We offer several helper packages for specific use cases. Our semantic layer is to add LLM telemetry to OpenTelemetry. Automatically instrumenting popular packages. Phoenix's open-source library supports tracing for AI applications, via manual instrumentation or through integrations with LlamaIndex, Langchain, OpenAI, and others. LLM tracing records the paths taken by requests as they propagate through multiple steps or components of an LLM application.
