DeepSeek API Simultaneously Launches V4-Pro and V4-Flash

According to Golden Finance, on April 24, DeepSeek announced that the DeepSeek API has now simultaneously launched V4-Pro and V4-Flash, supporting the OpenAI ChatCompletions interface and the Anthropic interface. When accessing the new models, the base_url remains unchanged, but the model parameter needs to be updated to deepseek-v4-pro or deepseek-v4-flash. The maximum context length for V4-Pro and V4-Flash is 1M, and both support non-thinking mode and thinking mode. In thinking mode, the reasoning_effort parameter can be set to adjust the intensity (high/max). For complex Agent scenarios, it is recommended to use thinking mode and set the intensity to max.
