Velvet, now an integral part of the Arize AI platform, originated as a dedicated developer gateway focused on the analysis, evaluation, and monitoring of AI-powered features. Following its acquisition by Arize, the enterprise leader in AI evaluation and observability, Velvet's core capabilities have been expanded and integrated into a more comprehensive ecosystem. This powerful synergy helps developers and MLOps teams accelerate the development of AI applications and agents, ensuring they perform optimally in production.

The platform addresses the entire lifecycle of AI development. It combines the enterprise-grade observability of Arize, the open-source LLM tracing and evaluation power of Phoenix, and the versatile model management of LiteLLM. This unified approach provides a single, cohesive environment for building, debugging, and maintaining sophisticated AI systems, particularly those leveraging Large Language Models (LLMs).

How to use usevelvet

As Velvet's technology is now embedded within the Arize platform, the workflow involves using the Arize ecosystem:

1. Integration: Start by integrating the Arize or Phoenix SDK into your AI application. This is typically done with a few lines of code in your Python or JavaScript environment where your model is being called.
2. Data Logging: Log model inputs (prompts), outputs (responses), and other metadata such as latency, token usage, and user feedback to the platform. For complex agentic workflows, you can log entire traces to visualize the sequence of operations.
3. Monitoring & Analysis: Use the Arize dashboard to get a real-time view of your AI application's performance. Monitor key metrics like response quality, data drift, and performance regressions. Set up automated alerts to be notified of any issues.
4. Evaluation & Debugging: Dive deep into individual traces using Phoenix to understand why a model produced a specific output. Evaluate responses against predefined criteria, compare different prompt versions, and identify root causes of failures.
5. Optimization: Use the insights gained from monitoring and evaluation to refine your prompts, fine-tune your models, or adjust your application logic. Leverage the LiteLLM gateway to manage different LLM providers, implement fallbacks for reliability, and control operational costs.

Core Features of usevelvet

• Unified AI Observability: A centralized platform to monitor, troubleshoot, and evaluate all your AI models, from traditional ML to generative LLMs.
• LLM Tracing and Evaluation: Powered by the open-source Phoenix library, it offers detailed tracing of LLM chains and agents, enabling real-time evaluation, experimentation, and optimization.
• Production Performance Monitoring: Automatically track model drift, performance degradation, and data quality issues in live environments.
• Root Cause Analysis: Advanced tools to quickly diagnose and resolve issues, pinpointing problems with specific data segments, prompts, or model versions.
• Multi-LLM Gateway (via LiteLLM): Provides a unified interface to interact with over 100+ LLMs, standardizing API calls and enabling features like model fallbacks, retries, and spend tracking.
• Scalability for Enterprise: Built to handle the demands of large-scale enterprise applications, ensuring reliability and security.

Use Cases for usevelvet

The platform is ideal for a wide range of applications and teams:
