REST APIs
March 6–11, 2026 New REST API endpoints for managing core platform resources programmatically:- Prompt Version & Label Management: Create, retrieve, and manage prompt versions with labels like “production” for easy resolution. List all versions of a prompt, create new versions with commit messages, and set/replace labels on versions. Labels automatically move when reassigned, ensuring the correct version is always referenced.
- API Keys Management (Python & JavaScript SDKs): Create, list, and delete API keys programmatically through Python and JavaScript SDKs. Two types of keys available: user keys that inherit individual user permissions and can be created in multiples, and service keys tied to bot users for organizational continuity. Enables secure automation and integration with external systems while ensuring service accounts remain functional even when team members leave.
- AI Integrations: List, create, update, and delete integrations with cursor-based pagination and space filtering. Connect Arize AX with various AI frameworks like OpenAI Agents, LangGraph, and Autogen for automatic instrumentation and monitoring with just a few lines of code, dramatically simplifying observability infrastructure.
- Evaluators: List evaluators programmatically with cursor-based pagination and space filtering. Each evaluator includes ID, name, description, space ID, task type, tags, current version, and timestamps. Transform subjective AI outputs into measurable, trackable metrics that enable teams to confidently iterate on applications and ensure consistent quality at scale.
- Annotation Queue Records: Retrieve annotation queue records via REST API with pagination support. View annotations, assigned users with status, source data, and evaluations for each record. Streamlines the annotation workflow by providing programmatic access to centralized data labeling processes, ensuring organized and consistent annotation tracking across teams.
Alyx Improvements
March 6–9, 2026- Bedrock Integration: Use AWS Bedrock integrations as the model powering Alyx. Pass provider parameters (region, anthropic_version, etc.) through the full stack from UI to generative services. A warning icon appears when a Bedrock integration is selected without a configured region, opening a dialog to persist parameters to localStorage for automatic message retry.
- Session Reading: Alyx can now read and analyze sessions with two new tools: get session table preview for an overview of the sessions table, and get session data to see all traces within a session. Regardless of selected time range, tools that fetch assets by ID now look in a minimum 60-day window. Improved large JSON compression logic maintains valid JSON structure and adds pagination indicators.
CLI Commands
March 9, 2026 New CLI commands for managing annotation configs and exporting data:- Annotation Configs CRUD: Create, list, and delete annotation configs through the CLI. Reusable schemas define how to structure human feedback and evaluations across your workspace with consistent rubrics (categorical labels, continuous scores, or freeform text). Consistent annotations enable better error analysis, help build high-quality training datasets, and provide reliable ground truth data for improving prompts and model fine-tuning.
- Dataset, Experiment, and Span Export: Export datasets, experiments, and spans using new CLI commands. Download all examples from datasets, all runs from experiments, or spans filtered by trace/span/session ID. Append examples to existing datasets from inline JSON or files (CSV, JSON, JSONL, Parquet) with client-side structural validation and server-side field-level validation.
