--- description: Available in Phoenix 11.7+ --- # 07.13.2025: Experiments Module in phoenix-client 🧪 {% embed url="https://pypi.org/project/arize-phoenix-client/" %} **New Features in Phoenix 11.7+:** * Added a new `experiments` property to both `Client` and `AsyncClient` for invoking experiment workflows. * Introduced `Experiments` and `AsyncExperiments` classes with `run_experiment` methods supporting **tasks, evaluators, dry-run mode**, and **metadata**. * Implemented `SyncExecutor` and `AsyncExecutor` classes for **concurrent execution** with built-in **progress bars**. * Added `RateLimiter` and `AdaptiveTokenBucket` for intelligent handling and throttling of **rate-limit errors**. **Bug Fixes:** * Fixed a typo in the `datasets.get_dataset_versions` docstring. **Enhancements:** * Introduced a `PhoenixException` base class and **refactored exception imports** for consistency. * Simplified rate limiter output by replacing `printif` with direct print statements. {% embed url="https://github.com/Arize-ai/phoenix/pull/8375" %}
