Granite-4.0-H-Small: a 32B-A9B MoE Mamba for high efficency

Damn! IBM is on the map. The American Qwen? I barely even knew IBM made LLMs, this is solid

www.ibm.com/new/announce...

The bar chart is titled **“Retrieval Augmented Generation (RAG)”** and shows **MTRAG mean accuracy** on the y-axis (0–80 scale).

### Results by model:

* **Granite-4.0-H-Small**: **73** (blue bar, highest)
* **Granite-4.0-Micro**: **72** (blue bar, nearly tied with H-Small)
* **GPT-OSS-20B**: **68** (green bar)
* **Mistral-Small-3.2-Instruct**: **48** (green bar, lowest score)
* **Llama-3.2-Instruct**: **53** (green bar)
* **Llama-3.3-70B-Instruct**: **61** (green bar)
* **Qwen3-8B**: **55** (green bar)

### Key takeaway:

The **Granite-4.0 models (H-Small and Micro)** outperform all others, achieving ~73 accuracy, with GPT-OSS-20B in third at 68. The weakest performance is from **Mistral-Small-3.2-Instruct (48)**.

Recently got to have a super interesting conversation with the infinitely fascinating @krvarshney.bsky.social about why we need to make AI safe, and the very nature of ethics in a disaggregated digital world. Have a watch !

Why do AI models need to be safe?

"In my own interactions with ChatGPT, it has often responded, with patently insincere flattery: “That’s a great question.” It has never responded: “That’s the wrong question.” It has never challenged my moral convictions or asked me to justify myself."

"Until we recognise that the debate about AI is not just about what machines can do but also about how humans should value education and knowledge, it will remain mired in confusion." observer.co.uk/news/opinion...

"The true measure of progress in AI lies not in the sophistication of algorithms but in whether it genuinely serve the people and communities they seek to empower. Without grounding in human dignity and local contexts, AI risks creating technological subjugation."

Joining @baratunde.com on his Life with Machines podcast show was a 2024 highlight.

Speaking both before and after the US presidential election, we talked about technology, democracy, and the AI Bill of Rights. And I advance a #StephCurry theory of AI innovation.🏀

"Training yourself to observe and challenge these automatic thoughts—what psychologists call metacognition—is strikingly similar to the Buddhist concept of yoniso manasikāra, or wise attention." www.forbes.com/councils/for...

Selective Thinking Is The Skill Every Leader Needs

When you observe your mind without being swept away, you take back control from unconscious, emotional thinking—the kind that fuels rash decisions and poor leadership.

"The next decade will be shaped by innovators using AI to solve real problems in real communities. The future won’t be written in Silicon Valley, but in Lagos, Jakarta, Cairo and Dubai. AI-powered solutions fused with local knowledge will unlock this future." www.weforum.org/stories/2025...
