Overview
DeepSeek-V4: The "Silent Reasoning" Monster (Jan 2026)
Rating: 9.9/10 (Best Open Model)
1. Executive Summary
Released in January 2026, DeepSeek-V4 is a massive Mixture-of-Experts (MoE) model that introduces the revolutionary "Silent Reasoning" protocol. It outperforms GPT-4.5 Turbo on coding and logic tasks while running at 40% of the inference cost.
2. Core Features
- Silent Reasoning: Performs "Chain of Thought" processing without outputting tokens, saving costs while boosting logic.
- Sandbox Execution: Integrated code interpreter supporting Python, Rust, and Go.
- 128k Context: Optimized for "Needle In A Haystack" retrieval.
- Open Weights: Weights are open-sourced (Apache 2.0 for Base).
3. Benchmarks (Jan 2026)
- HumanEval (Python): 94.1% (vs GPT-4.5 Turbo 92.8%)
- GSM8K (Logic): 96.5%
- API Cost: $0.80/1M tokens (vs GPT-4.5 $5.00)
4. Use Cases
- Local Hosting: Efficient enough for high-end local setups.
- Logic-Heavy Coding: Best-in-class for complex algorithmic problems.
Use Cases
Local inference
Complex logic
Privacy-focused coding
