DeepSeek-V4-Flash Discount Offer Officially Takes Effect, B.AI Adds Another 50% Off on Peak-Valley Pricing

Odaily News - On September 3, the discount offer for DeepSeek-V4-Flash and DeepSeek-V4-Flash-Vision-Exp on the B.AI platform officially took effect. The platform has applied an additional 50% discount across the board on top of DeepSeek's official peak-valley pricing mechanism — during peak hours, users pay only 50% of the official price, while during off-peak hours, costs drop to as low as 25% of the official peak-hour price. A single API call can save up to 75%. Whether for high-concurrency tasks, Agent workflows, or large-scale API calls, B.AI remains the most cost-effective choice for developers using DeepSeek-V4-Flash. Meanwhile, four popular models — GLM-5.3-Flash, Qwen3.8-Flash, Hy3, and MiMo V2.5 — remain 100% free, covering diverse needs such as inference, multimodal applications, and Chinese-language scenarios.
