From 2f80c977c4cc886a5b56723c3339dae98fe3b768 Mon Sep 17 00:00:00 2001 From: ionmincu Date: Wed, 6 May 2026 16:14:26 +0300 Subject: [PATCH] fix: promote provider-specific chat models in docs and new template Replace UiPathChat references with UiPathChatAnthropicBedrock, UiPathChatBedrockConverse, UiPathAzureChatOpenAI, and UiPathChatVertex. Drop hardcoded model lists in favour of `uipath list-models`. Update the `uipath new` template to use UiPathChatAnthropicBedrock by default.
