DeepSeek V4 Surprise Launch on Lunar New Year? Netizens: 'A Whale Fall Nourishes All Things'

Today is March 16, Lunar New Year's Eve.

While everyone is preparing for their reunion dinners, rumors in the AI community have reached a boiling point: DeepSeek V4 is extremely likely to launch tomorrow (Lunar New Year's Day) as a 'New Year Gift'.

This is not groundless.

The latest leaks suggest that the V4 release is not just a version iteration. It represents the first time an open-source model has directly confronted and beaten top-tier closed-source models on core metrics. Netizens have used a vivid phrase to describe this potential launch: "A Whale Fall Nourishes All Things" (一鲸落，万物生).

This doesn't mean DeepSeek is "dying". It metaphorically means that once its massive open weights are released, that immense energy will nourish the entire ecosystem, allowing countless small applications and tools based on it to grow wildly like life on the ocean floor. The moat of closed-source models might truly be filled.

83.7%: The Number That Silenced Everyone

The most widely circulated benchmark screenshot shows DeepSeek V4 achieving 83.7% on SWE-bench Verified.

If this number is true, it is terrifying.

You have to realize that the current closed-source ceilings, Claude 3.5 Opus (Opus 4.5) and GPT-5.2, are both below this score. SWE-bench measures AI's ability to solve real GitHub issues, not toy problems like reciting poetry or doing arithmetic. 83.7% means it might be more reliable at writing code and fixing bugs than most junior programmers.

What does this mean?

It means that in the future, when you build AI coding tools (like Cursor, Windsurf), you no longer need to beg for OpenAI API quotas or endure expensive Claude calls. You can distill DeepSeek V4 or deploy it directly. The effect might be better, and the cost could be nearly zero.

Why Lunar New Year?

Why choose tomorrow (March 17) to launch?

Besides the romantic notion of "giving a Red Packet to global developers," I think it's more of a tactical confidence.

Just like blockbuster movies dare to release during the Spring Festival, only those with absolute confidence in their quality dare to release at a time when everyone is busy visiting relatives. They know that as long as the product is hard-core enough, hardcore players will definitely put down their Red Packets to run the model.

Stay Tuned

We will continue to stare at GitHub and HuggingFace. If the "Whale Fall" really happens, it will be the best gift to the global open-source community in 2026.

Happy Lunar New Year! May your GPUs stay cool and your models converge!
