Changelog Entry

Description

Fix Azure OpenAI connections on custom base URLs (hostnames without azure. / cognitive.microsoft.com). Selecting Azure OpenAI in the connection modal now persists azure: true, and the backend treats provider: "azure" as Azure mode so verify and chat use deployment API paths (/openai/models, /openai/deployments/{model}/chat/completions).

Added

is_azure_openai_config() helper in routers/openai.py for consistent Azure routing checks.

Changed

AddConnectionModal.svelte: save azure: true whenever Azure mode is active (including when Provider is Azure OpenAI), not only on URL auto-detection.
routers/openai.py: use is_azure_openai_config() instead of api_config.get('azure', False) for verify, models, and chat completion routing.

Fixed

Azure OpenAI provider failing on custom gateway URLs: Verify showed “Network error” and chat returned no reply because only provider: "azure" was saved without azure: true, so requests hit /models and /chat/completions instead of Azure deployment endpoints (#24872).

Additional Information

Problem

The Azure OpenAI provider in Admin Panel → Settings → Connections is intended for gateways that use the Azure deployment API (APIM, private endpoints) where the hostname does not trigger auto-detection (azure. / cognitive.microsoft.com).

On save/verify, the UI used:

...(provider ? { provider } : azure ? { azure: true } : {})

Choosing Azure OpenAI stored provider: "azure" but omitted azure: true. The backend only checked api_config.get('azure', False), so verify and chat used generic OpenAI paths and failed on Azure-compatible gateways.

Solution

Frontend: Always persist azure: true when Azure mode is active; keep provider: "azure" when selected.
Backend: is_azure_openai_config() returns true for azure: true or provider === 'azure' (backward compatibility for existing saved configs).
