From 0bc72cfd654afa6226cfc75bd374da8c67070d5d Mon Sep 17 00:00:00 2001 From: Diego Rodrigues de Sa e Souza Date: Fri, 7 Aug 2026 18:08:30 -0300 Subject: [PATCH] fix(providers): manual Vision capable override does not affect Combo routing (#9195) Three linked bugs prevented the Custom Models 'Vision capable' toggle from affecting Combo routing, causing 400 capability_mismatch on image requests sent through Combos targeting a custom vision model. Bug #1 (catalog, dead guard): modelType === 'chat' was always false for chat models because modelType was only assigned 'embedding', 'rerank', 'image', or 'audio'. Changed the guard to !modelType || modelType === 'chat' so getCustomVisionCapabilityFields() fires for custom chat models. Bug #2 (catalog, synced-first ordering): When a model appeared in both syncedAvailableModels (from discovery) and customModels, the custom row was skipped entirely, losing the vision override. Now merge vision fields into the existing synced entry when the custom model has an explicit supportsVision boolean. Bug #3 (routing capabilities): getResolvedModelCapabilities() / resolveVisionCapability() had no path to consult the customModels supportsVision flag. Added a sync DB lookup helper and a new customVisionOverride parameter so the dashboard toggle affects Combo routing.
