Chinese AI Model Promises Gemini 2.5 Pro-level Performance at ...
Hello AI Enthusiasts! Welcome to the Twenty-Fourth edition of "This Week in AI Engineering"! This week, the spotlight shines on MiniMax, the Chinese AI startup that just released a frontier-level open-weight reasoning model, MiniMax-M1, with some jaw-dropping benchmarks. We also saw Google introduce a new Flash-Lite variant that's faster and cheaper. Meanwhile, Kimi-Dev-72B emerges as one of the strongest open-source coding models ever, targeting real-world debugging workflows with a two-agent architecture. As always, we’ll wrap things up with under-the-radar tools and releases that deserve your attention.
Chinese startup MiniMax
Chinese startup MiniMax is back in the spotlight with their new open-weight reasoning model, MiniMax-M1, and it is nothing short of impressive. M1 supports a context window of 1 million tokens, putting it in the same class as Gemini 2.5 Pro. But here’s the kicker: thanks to its hybrid Mixture-of-Experts architecture and lightning attention mechanism, it achieves the same reasoning quality as DeepSeek R1 at just 25% of the compute cost. And yes, it’s completely open sourced.
Training Cost
Google has officially made Gemini 2.5 Pro and Flash generally available for production use. These hybrid reasoning models have already been deployed by partners like Snap, Rooms, and SmartBear. But the real highlight is the new Gemini 2.5 Flash-Lite, now in preview. It’s the fastest and cheapest model in the 2.5 family. Despite that, it outperforms Gemini 2.0 Flash-Lite in coding, math, reasoning, science, and multimodal benchmarks.
Moonshot AI’s new Kimi-Dev-72B
Moonshot AI’s new Kimi-Dev-72B just hit 60.4% on SWE-bench Verified, making it the strongest open-weight coding model right now. What makes Kimi-Dev different is its dual-agent setup. The model uses two specialized agents:
