deepseek-flash-fast: DeepSeek V4.1 Flash 1017, the current version, on its standard weights from a private deployment. It is not abliterated and keeps the base model's refusal behaviour. Text and image input, a 1,048,576-token context and up to 262,144 output tokens. Reasoning modes are none, low (the default), high and max; none turns reasoning off. Fixed prices apply at all hours, without DeepSeek's peak-hour multiplier.
