Description

The model perplexity/glm-5.3 is listed on Perplexity's Agent API pricing page with per-token pricing but is missing from model_list.json. The underlying model already exists in the catalog as zai-org/GLM-5.3 (line ~10904) with available_providers: ["baseten"] and matching input/output pricing.

The sibling model perplexity/glm-5.2 is also missing from the catalog and tracked in issue #1111.

Closing this bot issue because perplexity/glm-5.3 is on the permanent sync-exclusion list (MANUAL_SYNC_EXCLUDED_MODELS / deprecated_model_ids.json in sync_models.ts) or a Perplexity Gateway (router) model the proxy cannot route, and must not be auto-added to the catalog.
