deepseek-chat (legacy alias)

Deprecated

Legacy model-name alias, NOT a separate model. Official docs: 'deepseek-chat & deepseek-reasoner will be fully retired and inaccessible after Jul 24th, 2026, 15:59 (UTC Time). (Currently routing to deepseek-v4-flash non-thinking/thinking).' deepseek-chat = NON-thinking mode of deepseek-v4-flash. Exact retirement timestamp: 2026-07-24 15:59 UTC. Replacement: use explicit name deepseek-v4-flash (non-thinking). Pricing shown matches deepseek-v4-flash since it routes there. This alias historically mapped to DeepSeek-V3-series non-thinking; as of the V4 Preview it routes to V4-Flash.
