January 27, 2026, marks absolutely the craziest 24 hours in AI history!

Following Qwen3-Max's explosive debut last night and DeepSeek OCR 2's surprise attack this afternoon, Kimi 2.5 has officially drawn its sword!

As DeepSeek's "old rival," Moonshot AI's choice to release Kimi 2.5 at this moment is obvious: to completely block the "long-context reasoning" track before DeepSeek V4's New Year's Eve launch event.

Crazy 24 Hours: Kimi 2.5 Joins the "Siege"! Is DeepSeek V4's New Year's Eve Battle in Jeopardy?

If last year's large models were competing on parameters, then this January 2026 "Battle Royale" is all about Reasoning Depth.

With the release of Kimi 2.5, the domestic large model "Three Musketeers" (Qwen, DeepSeek, Kimi) have completed their final assembly before the Spring Festival. This epic siege against DeepSeek V4 has reached a fever pitch.

1. Kimi 2.5: Not Just "Longer," But "Deeper"

According to the latest technical documentation and preliminary reviews, Kimi 2.5 has achieved a qualitative leap based on the 2025 K2 architecture:

• Ultra-Deep Multi-step Reasoning: Kimi 2.5 has hit a new high score on the hellishly difficult HLE (Humanity's Last Exam) test. Its strength lies in its ability to perform 200-300 continuous thought calls without "blanking out" when given an extremely complex logical trap.
• End-to-End Engineering Capability: The previous K2 had already shown terrifying combat capabilities on Terminal-Bench and SWE-bench, while Kimi 2.5 is said to be able to independently complete the refactoring of medium-sized software projects.
• KV Cache VRAM Revolution: Continuing the K-series' extreme optimization of KV Cache, Kimi 2.5 remains one of the most cost-effective long-text reasoning models on the market.

2. DeepSeek V4's "Besieged on All Sides"

As the webmaster, I am both excited and sweating for DeepSeek. Look at the current battlefield:

1. Left Wing (Alibaba Qwen3-Max): Focuses on versatility and autonomous tool calling, playing the "family bucket" ecosystem to the extreme.
2. Right Wing (Moonshot AI Kimi 2.5): guarding the high ground of long text and deep reasoning, making it irresistible for all text workers and programmers.
3. Center (OpenAI GPT-5.2): Remains that high mountain of cost and intelligence that is hard to climb.

Does DeepSeek V4 still have a chance?

Don't forget the Engram (Memory Trace) technology we disassembled before. Although Kimi 2.5 has deep reasoning, it still has architectural ceilings when facing real-time retrieval responses for million-level tokens. If DeepSeek V4 can use Engram to achieve "millisecond-level global memory awakening," it will practically be the only "external brain" king of 2026.

3. Spring Festival 2026: Who Will Get the Final Ticket?

The release of Kimi 2.5 has actually backed DeepSeek into a corner: V4 must produce a new concept surpassing "deep reasoning" on New Year's Eve.

If V4 is just another "stronger reasoning model," it will be hard to break out from the pincer attack of Qwen3 and Kimi 2.5. Unless, as we predicted, it has achieved a "nuclear fission" of logic and cost.
