DeepSeek: DeepSeek V3.1

This advanced AI model offers two modes in one: a “thinking” mode for deep, chain‑of‑thought reasoning and a “non‑thinking” mode for fast, direct answers. It handles very long inputs (up to ~128K tokens), making it ideal for analyzing hundreds of pages, long dialogues, and complex multi-step tasks. It can act as an agent for code generation, tool invocation, and planning, switching modes in‑prompt for cost and latency control. Optimizations like FP8 micro‑scaling improve inference efficiency, though substantial hardware may still be required. Use it for long-context analysis, reliable tool calls, and flexible workflows that balance speed with high‑quality reasoning.
