We've built a top-tier agent that's actually useful: your best friend for building, debugging, and improving AI. This release highlights new skills, model options, and integrations. #### Alyx by surface Alyx adapts to where you are in the platform and exposes the right skills: * **Trace slideover** — Trace troubleshooting, span analysis, annotations, build evals * **Prompt Playground** — Optimize prompts, build evals, run experiments * **Eval Builder / Task Builder** — Build custom evals, configure tasks * **Traces table (AI Search)** — Natural language to filter syntax in the traces table * **Traces page** — Multi-trace analysis, pattern discovery, categorization * **Datasets & Experiments** — Analyze experiments, manage datasets, synthetic data #### Cross-cutting skills * **ArizeQL Generator** — Turn natural language or existing code (SQL, Python) into AQL for custom metrics * **Optimize Prompts** — Improve prompt quality or target specific issues #### Use your own integrations Use **OpenAI** or **Anthropic** (via AWS Bedrock and Vertex AI) with Alyx. Add and manage integrations in **Settings** → Account Settings → Integrations. More providers coming soon. #### Default model **Claude Sonnet 4.5** is now the default model for Alyx, giving you a strong balance of speed and capability out of the box. You can change the model in Alyx settings or via your configured integrations.
