B.AI Model Pricing Adjustment: DeepSeek V4 Flash Will Launch at 50% Off Billing, Multiple Free Models Still Available

Odaily News – September 2: The B.AI platform announced that starting from 17:00 (SGT) on September 3, 2026, DeepSeek V4 Flash and DeepSeek V4 Flash Vision Exp will end their free trial period and officially enter a 50% discounted billing phase. Prior to this time, both models will remain free to use. Meanwhile, B.AI will adopt DeepSeek's official peak/off-peak pricing mechanism, with additional tiered discounts: During peak hours (weekdays 09:00–12:00, 14:00–18:00 SGT), billing is set at 50% of the official original price; during off-peak hours (remaining weekday periods and all weekends), an additional 50% discount applies, bringing the effective rate to 25% of the official original price.

For users who wish to continue enjoying a free experience, the GLM 5.3 Flash "Niu Lai" model will remain free of charge. This model features 320B total parameters with 18B activated parameters, supports a 1M context window, and combines robust reasoning capabilities with rapid response speeds, making it a high cost-performance choice for high-frequency calls.

In addition, Qwen3.8 Flash, Hy3, and MiMo V2.5 will also continue to be offered for free. B.AI will keep optimizing its model offerings and pricing structure to provide developers with more high-performance, high-value AI model options.
