DeepSeekV4.app Exclusive | 2026-02-27 | Editor: UIO

A massive seismic shift is hitting the AI world. According to multiple verified sources, DeepSeek V4 is expected to launch officially within the next week.

Currently, a version titled DeepSeek V4 Lite (internal code-name: Sealion-lite) is undergoing closed beta testing across select inference providers. Based on leaked specifications, V4 isn't just an upgrade—it's a complete paradigm shift for the industry.

🟢 Leaked Specs: The Insane Power of Sealion-lite

According to sources involved in the beta testing, DeepSeek V4 Lite is delivering jaw-dropping performance:

• 1 Million Token Context: V4 Lite natively supports a 1M context window, multiple times the capacity of current production models.
• Native Multimodal capabilities: Moving beyond visual plugins, V4 is a true native multimodal model, showing a massive leap in both image understanding and generation.
• SVG Quality Crushes V3.2: A comparison chart going viral on X (formerly Twitter) shows that V4 Lite (without thinking mode enabled) generates higher quality SVG graphics than even the V3.2 thinking model.

🔴 Bypassing Nvidia: Prioritizing Domestic Silicon

In a tactical move that breaks industry conventions, Reuters reports that DeepSeek has not given early access to Nvidia.

Instead, sources claim DeepSeek has entered a deep collaboration with a top-tier domestic chipmaker (rumored to be Huawei). V4 was reportedly co-engineered from its inception with the Ascend operator library. This suggests that Chinese AI is aggressively pivoting toward a hardware-software integrated stack to break free from the CUDA ecosystem.

🔵 Panic in the West: An Organized Media Onslaught?

As the V4 launch nears, US media and tech giants have entered an unprecedented "attack mode":

1. FUD Marketing: Outlets like CNN and NYT are publishing frequent reports claiming DeepSeek was trained on "illegally obtained GPUs."
2. Distillation Accusations: Anthropic has publicly accused DeepSeek of lacking innovation and merely "distilling" data from Claude.
3. Identity Irony: In a bizarre twist, users recently discovered that when its system prompt is cleared, Claude Sonnet 4.6 identifies itself as "DeepSeek V3 developed by DeepSeek." This has led to intense community mockery of Anthropic's claims.

Analysts suggest this coordinated wave of "Fear, Uncertainty, and Doubt" (FUD) is aimed at stabilizing Nvidia's stock and buying time for US-based AI companies to secure funding.
