What is DeepSeek V4?
DeepSeek V4 is the upcoming flagship AI model from Chinese AI startup DeepSeek, a specialized Large Language Model designed primarily for coding and software development tasks. It's the successor to the V3 model that DeepSeek released in December 2024. DeepSeek V4 is expected to launch in mid-February 2026, likely around February 17 to coincide with Lunar New Year celebrations.
DeepSeek uses a Mixture of Experts (MoE) architecture that is more energy-efficient than classic dense models. V3 already had 671 billion parameters, with only a portion being activated per prompt. DeepSeek has attracted attention with efficient training approaches — training their R1 model reportedly cost only $294,000, significantly less than comparable US models.
Internal tests by DeepSeek employees show V4 may outperform rivals like Anthropic's Claude and OpenAI's GPT series specifically in coding tasks. The key benchmark to watch is SWE-bench, where Claude Opus 4.5 currently leads with an 80.9% solve rate. DeepSeek is expected to release V4 as an open-weight model, continuing their tradition of making powerful AI accessible to the broader community.
DeepSeek V4 Features
DeepSeek V4 offers repo-level reasoning — the ability to understand how changes in one file affect other files across a project, making it particularly valuable for developers working with large codebases or complex distributed systems.
DeepSeek V4 introduces a new Engram conditional memory system for near-infinite context retrieval, enabling it to process extremely long coding prompts and maintain context across large codebases.
DeepSeek V4 positions itself as a specialized "coding king" challenger. The model is expected to be released as open-weight, continuing DeepSeek's tradition of making powerful AI accessible to the broader community — a stark contrast to the closed approaches of Western competitors.
DeepSeek's previous models, particularly V3 and R1, proved that open-source AI models could compete with proprietary ones at a fraction of the cost. V4 is expected to build on this success with even more impressive coding capabilities.
DeepSeek V4 will be easily accessible through Overchat AI, where you can chat with it alongside other top AI models like GPT-5.2, Claude Opus 4.5, and Gemini 3 Pro — all in one convenient interface.
DeepSeek V4 Benchmarks
Internal tests by DeepSeek employees show V4 may outperform rivals specifically in coding tasks. The key benchmark to watch is SWE-bench, where Claude Opus 4.5 currently leads with an 80.9% solve rate — DeepSeek V4 aims to challenge that position.
