B.AI Model Privileges Update: DeepSeek V4 Flash will be billed at half price, while multiple free models remain freely accessible.

The B.AI platform announced that effective September 3, 2026, at 17:00 (SGT), DeepSeek V4 Flash and DeepSeek V4 Flash Vision Exp will conclude their free trials and officially transition to discounted billing at 50% of the official price. Prior to this date, both models will remain available for free. Additionally, B.AI will align with DeepSeek’s official peak-and-off-peak pricing structure and apply stacked discounts: during peak hours (workdays 09:00–12:00 and 14:00–18:00 SGT), usage will be billed at 50% of the official list price. During off-peak hours (remaining workday periods and all day on weekends), an additional 50% discount applies, resulting in a final rate of 25% of the official list price.
