What Is DeepSeek Chat?
DeepSeek Chat is the free web and mobile chat interface for DeepSeek's AI models, with the underlying API offering genuinely competitive pricing through two tiers as of September 2026: DeepSeek-Flash (V4.1-Flash) at $0.30/$1.20 per million input/output tokens during peak hours (dropping to $0.15/$0.60 off-peak), and DeepSeek-V4-Pro at $1.32/$3.96 peak ($0.66/$1.98 off-peak) for higher capability needs.
Its peak/off-peak pricing structure is a genuinely distinctive detail worth understanding for cost-conscious API users: peak hours run 01:00-04:00 and 06:00-10:00 UTC on weekdays, which falls during nighttime across the United States — meaning a US-based team running batch jobs during their normal workday automatically qualifies for the cheaper off-peak rate, effectively halving API costs for anyone whose usage naturally avoids those UTC peak windows. New API signups also get a free 5-million-token grant valid for 30 days (no credit card required), enough for roughly 2,500-5,000 test calls depending on prompt length.
It's aimed at developers wanting a low-cost, capable AI model API, with the peak/off-peak pricing structure specifically rewarding US and non-Asia-Pacific teams whose normal working hours fall outside the UTC peak window.
