feat(llmobs): remote evaluation devserver POC by alexbarksdale · Pull Request #16665 · DataDog/dd-trace-py

alexbarksdale · 2026-02-25T20:33:18Z

Summary

Adds a lightweight HTTP devserver (_devserver.py) that exposes registered Experiment objects via /list and /eval endpoints, enabling remote/UI-driven experiment execution with NDJSON streaming support
Extends Experiment with remote_config (typed config fields for UI rendering), progress_callback / on_start hooks, and span event capture for real-time progress reporting
Adds LLMObs.devserver() class method and LLMObs.async_experiment() / LLMObs.experiment() accept a new remote_config parameter
Includes a runnable example (_examples/devserver_example.py) demonstrating the full flow

Test plan

Run the devserver example end-to-end: DD_API_KEY=... DD_APP_KEY=... DD_SITE=... python -m ddtrace.llmobs._examples.devserver_example
Verify /list returns experiment metadata and config schema
Verify /eval with stream: false returns JSON results
Verify /eval with stream: true returns NDJSON progress events
Verify config_override and evaluators filtering work correctly
Verify CORS headers are set properly

…o Experiment - Add ConfigFieldType and ConfigField types for typed devserver UI config schema - Add remote_config parameter to Experiment, SyncExperiment, and LLMObs factory methods - Add _user_tags to preserve user-provided tags before auto-tag injection - Add ProgressEvent, ProgressCallbackType, and OnStartCallbackType - Add span_event to TaskResult for full span data after task completion - Thread progress_callback and on_start through run(), _run_task(), _process_record() - Add _emit_post_eval_progress() for evaluation-complete and success events - Add LLMObs.devserver() classmethod Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

HTTP devserver that exposes registered experiments for remote execution. Supports NDJSON streaming (/eval with stream=true), config overrides, evaluator selection, sample sizing, and CORS. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Capital-city experiment demonstrating async task, evaluators, remote_config with typed fields, and devserver startup. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
