Product changes

• Web fetch: Parallel engine -- The web fetch server tool now supports Parallel as an engine option, bringing engine parity with web search.
• Delete all chats in chatroom -- Added a "Delete All Chats" option in the chatroom sidebar with a confirmation dialog for bulk-deleting all chat rooms at once.
• Pareto Router default settings -- The Pareto Router can now be configured with a default coding quality tier in workspace plugin settings, removing the need to pass min_coding_score on every API request.
• Fixed: HTML-encoded characters in xAI tool-call arguments -- xAI Grok models that intermittently emit &, <, or > inside tool-call argument JSON now have those entities decoded server-side so downstream clients receive clean arguments.
• Fixed: compare page horizontal scroll at 4–5 models -- The compare page now properly enables horizontal scrolling when comparing four or five models.

New models
