DeepSeek / deepseek/deepseek-v4-pro
DeepSeek V4 Pro - access through LLMTR
DeepSeek V4 Pro targets teams that prioritize reasoning, agentic and coding quality over minimum unit cost. It offers a 1M-token context window and up to 384K output, with tool calls. For image input or a lower unit cost, `deepseek/deepseek-flash` is the better fit. DeepSeek applies peak-hour pricing to this model: every token item costs double on weekdays (Monday-Friday, Beijing time) between 01:00-04:00 and 06:00-10:00 UTC. Weekends and Chinese public holidays bill at the off-peak rate all day.
