New Chinese AI Model Destroys DeepSeek: 100X More Powerful

AI giants just got embarrassed. Baidu and MBZUAI have dropped two lean but insanely powerful reasoning models that flip the script on everything we thought mattered in AI. Baidu’s ERNIE-4.5-21B A3B Thinking uses a Mixture of Experts with only 3B active parameters per token, a 128K context window, and built-in tool use — and it’s completely open under Apache-2.0. Meanwhile, MBZUAI’s K2 Think takes a 32B backbone and supercharges it with step-by-step reasoning, verifiable rewards, agent-like planning, and blazing 2,000 tokens per second throughput. Both models are not just competitive with trillion-parameter giants — in many cases they’re smarter, leaner, and faster. This might be the clearest signal yet that efficiency, not brute force, is the real future of AI.

???? What You’ll See:
• Baidu’s A3B model with 21B parameters but only 3B active per token
• How Mixture of Experts and long-context training redefine efficiency
• MBZUAI’s K2 Think with verifiable rewards and agent-like inference
• Benchmark wins in math, coding, and science against much larger models
• Blazing speed with speculative decoding and Cerebras hardware
• Why both models staying open source is a huge deal
• The end of the trillion-parameter race and rise of lean reasoning AI

⚡ Why It Matters:
The biggest players believed size was everything — but Baidu and MBZUAI just proved them wrong. These new models show that smarter design, not raw scale, may define the next era of AI.
