DeepSeek (4 models)
| Model | Status | Announced | Deprecated | Sunset | Replacement | Source |
|---|---|---|---|---|---|---|
deepseek-v4-flash DeepSeek V4 Flash V4 Flash was retired when V4.1 Flash launched. The deepseek-v4-flash name is temporarily routed to V4.1 Flash, so calls still succeed but hit a different model. deepseek-flash is the new name for the current Flash model. V4 Pro is unaffected and DeepSeek says it will keep serving past 2026-09-14. | Sunsetted | Sep 10, 2026 | Sep 10, 2026 | Sep 10, 2026 | deepseek-flash | announce |
deepseek-v4-flash-vision-exp Experimental vision model launched 2026-08-21 and retired three weeks later. The name temporarily routes to V4.1 Flash, which has native vision. | Sunsetted | Sep 10, 2026 | Sep 10, 2026 | Sep 10, 2026 | deepseek-flash | announce |
deepseek-chat Legacy alias stopped serving on 2026-07-24 at 15:59 UTC. Same base URL and key, so migration is a one-line model parameter change. | Sunsetted | Jul 14, 2026 | Jul 24, 2026 | Jul 24, 2026 | deepseek-v4-pro | announce |
deepseek-reasoner Legacy alias stopped serving on 2026-07-24 at 15:59 UTC. Mapping trap: deepseek-reasoner routed to V4 Flash in thinking mode, not to the stronger V4 Pro, so a naive swap to deepseek-v4-pro changes cost. Teams running heavy reasoning on the old alias should pick the tier deliberately. | Sunsetted | Jul 14, 2026 | Jul 24, 2026 | Jul 24, 2026 | deepseek-v4-flash | announce |
