DeepSeek-V3.1 represents one of the most advanced evolutions in the landscape of next-generation artificial intelligence models. Developed by the DeepSeek-AI team, this model stands out for its ability to combine power, flexibility, and reasoning speed. Unlike many other models available today, DeepSeek-V3.1 was designed to operate in a hybrid mode, adapting seamlessly between a “thinking” (reflective) approach and a “non-thinking” (direct and concise) approach depending on the task.
Main Features
One of the most significant innovations introduced with DeepSeek-V3.1 is the ability to switch the model’s behavior with great ease. In “thinking” mode, the AI develops deeper internal reasoning, ideal for complex tasks and problem-solving that require articulated logic. In “non-thinking” mode, however, responses are immediate and concise, perfect for scenarios where speed is essential.
The model was trained through a two-phase process that greatly expanded its contextual handling capacity. The 32K token phase was scaled up to 630 billion tokens, while the 128K token phase reached 209 billion tokens, significantly improving memory and long-term reasoning capacity. The use of the UE8M0 FP8 format also ensures optimal compatibility with modern hardware architectures, enhancing performance without sacrificing accuracy.
Another strong point is its optimization for tool calling, which allows the model to intelligently use external tools. This makes DeepSeek-V3.1 particularly effective as an AI agent, capable of handling complex processes and multi-step interactions smoothly and naturally.
