# 05.10.2026: Playground Preferences

> Save a default provider and model for the Playground, and the metrics aside is now always visible on the project page.

# Default Playground Provider and Model

**Available in arize-phoenix 15.6.0+**

You can now save a personal default provider and model for the Playground from the **AI Providers** settings page. Phoenix stores the preference in your browser and uses it whenever you open a new Playground session. When no preference is set, Playground falls back to the existing default (OpenAI / gpt-4o).

If you've previously configured per-provider invocation parameters (model, temperature, max tokens), those saved settings still take precedence for your preferred provider — the preference acts as a starting point, not an override.

# Span Metrics Always Visible

**Available in arize-phoenix 15.6.0+**

The metrics aside — showing latency percentiles, token counts, and error rates — is now always visible on the right side of the spans table on the project page.
