DeepSeek V4 Pro and Flash officially launch mid-July with peak-hour pricing
Official V4 launches after 3-month preview, now with 2x peak pricing during Beijing business hours
Deep Dive
DeepSeek officially launches V4 in mid-July 2026, graduating from the preview available since April. The release introduces peak-hour pricing: 2× baseline during defined Beijing business windows, while off-peak remains at current preview pricing. The update also brings feature optimizations and performance improvements. Users previously calling their models 'deepseek-v4-pro' or 'deepseek-v4-flash' were using the preview, not the official release.
Key Points
- Official DeepSeek V4 Pro and Flash launch mid-July 2026, ending a preview that started in April 2026
- Peak-hour pricing introduced: 2x baseline during Beijing business windows; off-peak rates stay at current preview levels
- Feature optimizations and performance improvements included in the official release, with migration guide and pricing docs already published
Why It Matters
Developers relying on DeepSeek V4 preview must migrate to official models and plan for higher costs during peak hours.
