# 04.15.2025: Display Tool Call and Result IDs in Span Details
{% embed url="https://storage.googleapis.com/arize-phoenix-assets/assets/gifs/tool_calling_ids2.gif" %}
Tool call and result IDs are now shown in the span details view. Each ID is placed within a collapsible header and can be easily copied. This update also supports spans with multiple tool calls. Get started with tracing your tool calls [here](https://arize.com/docs/phoenix/tracing/llm-traces-1).

### Improvements and Bug Fixes 🐛
* **Performance**: Do not refetch tables when trace and span details closed
* **UI**: Redirect /v1/traces to root path
* **Playground**: Update GPT-4.1 models in Playground
