Pull Request Checklist\n\n- [x] Target branch:
dev\n- [x] Description: See below\n- [x] Changelog: See below\n- [x] Testing: Manual testing with a custom OpenAI-compatible backend returningmetain/v1/models. Verified: upstream meta appears in UI, DB overrides take precedence, DEFAULT_MODEL_METADATA still applies as base.\n- [x] Code review: Self-reviewed\n- [x] Title Prefix:feat\n\n# Changelog Entry\n\n### Description\n\nAllow OpenAI-compatible backends to include an optionalmetaobject in their/v1/modelsresponse entries. OpenWebUI readsprofile_image_url,description, andcapabilitiesfrom it — applying them as defaults that DB overrides andDEFAULT_MODEL_METADATAcan still override.\n\nThis enables managing model presentation (icons, descriptions, capability flags) as infrastructure-as-code on the backend side, without requiring manual configuration in the OpenWebUI admin UI for each model.\n\nPrecedence (lowest to highest):\n1.DEFAULT_MODEL_METADATAconfig (global blanket defaults for all models)\n2. Upstreammetafrom/v1/modelsresponse (model-specific from the provider)\n3. DB model override (admin UI / API)\n\n### Example upstream/v1/modelsresponse entry\n\njson\n{\n \"id\": \"claude-sonnet-4-20250514\",\n \"object\": \"model\",\n \"owned_by\": \"anthropic\",\n \"meta\": {\n \"profile_image_url\": \"https://example.com/anthropic-icon.png\",\n \"description\": \"Anthropic's Claude Sonnet 4\",\n \"capabilities\": { \"vision\": true }\n }\n}\n\n\n### Added\n\n- Upstream model metadata support: OpenWebUI now readsmeta.profile_image_url,meta.description, andmeta.capabilitiesfrom/v1/modelsresponse entries served by OpenAI-compatible backends (including Ollama)\n\n### Changed\n\n-get_all_models()inbackend/open_webui/utils/models.py— added a new loop after theDEFAULT_MODEL_METADATAblock that applies upstreammetafields, skipping models with DB overrides\n\n### Why no other files need changes\n\n- openai.py: Already preserves all upstream fields via**modelspread and stores the original inmodel[\"openai\"]\n- Frontend (Svelte): Already readsinfo.metafor display (profile_image_url,description,capabilities)\n\n---\n\n### Additional Information\n\n- ~26 lines of new code in a single file\n- No new dependencies\n- No frontend changes required\n- No breaking changes — purely additive; backends that don't includemetaare unaffected\n\n### Contributor License Agreement\n\n- [x] By submitting this pull request, I confirm that I have read and fully agree to the Contributor License Agreement (CLA), and I am providing my contributions under its terms.🔄 This issue represents a GitHub Pull Request.
