Amongst this week's model releases were Nvidia's Nemotron 3, OpenAI's ChatGPT Images and Google's Gemini Flash 3. Rumors are strong that GLM-4.7 and MiniMax 2.1 are imminent in their release. wrt tooling, Wispr Flow is now offering in India Purchasing Power Parity pricing of ₹320 ($3.5) per month instead of $12 per month Here's my referral link which gives you one month of free Pro subscription https://wisprflow.ai/r?YUSUF2 Readers who think others in their family, friends and acquaintances who have a curiosity in knowing more about rapidly evolving AI tools/services/use cases would benefit from being subscribers of this weekly newsletter are encouraged to share this publication link to them and invite them to subscribe The following messages were posted on the 'All Things AI' Telegram group from Sunday 14th Dec 2025 to Saturday 20th Dec 2025Sunday 14th December 2025Monday 15th December 2025Tuesday 16th December 2025Nvidia launches Nemotron 3, a family of AI models using a hybrid mixture-of-experts architecture and the Mamba-Transformer design, in 30B, 100B, and ~500B sizes This 31.6 billion parameter model uses a mixture-of-experts design, activating just 3.6 billion per token for top efficiency. It handles a 1 million token context and excels on benchmarks like SWE-Bench Verified at 38.8% for coding and GPQA Diamond for reasoning, beating rivals while running faster. Developers can run it locally on 24GB RAM, with full datasets, recipes, and tools released openly for commercial use Bryan Catanzaro @ctnzr Today, @NVIDIA is launching the open Nemotron 3 model family, starting with Nano (30B-3A), which pushes the frontier of accuracy and inference efficiency with a novel hybrid SSM Mixture of Experts architecture. Super and Ultra are coming in the next few months. 1,225 10:04 PM • Dec 15, 2025 Artificial Analysis @ArtificialAnlys NVIDIA has just released Nemotron 3 Nano, a ~30B MoE model that scores 52 on the Artificial Analysis Intelligence Index with just ~3B active parameters Hybrid Mamba-Transformer architecture: Nemotron 3 Nano combines the hybrid Mamba-Transformer approach @NVIDIAAI has used on 291 12:23 AM • Dec 16, 2025 Chubby♨️ @kimmonismus NVIDIA just open-sourced a 30B model that beats GPT-OSS and Qwen3-30B - and runs 2.2–3.3× faster.

The “hybrid thinking” switch controls whether it spends extra steps reasoning before answering, and the HTML generation and long context are aimed at agent loops where the model writes code, calls tools, reads outputs, and keeps going for hundreds of turns. Fuli Luo from the Xiaomi Mimo team is an ex-founding member of DeepSeek and core author of DeepSeek-V2. XiaomiMiMo @XiaomiMiMo Faster than Fast. Designed for Agentic AI. Introducing Xiaomi MiMo-V2-Flash — our new open-source MoE model: 309B total params, 15B active. Blazing speed meets frontier performance.

It’s just step 2 on our AGI roadmap, but I wanted to dump some notes on the engineering choices that actually moved the needle. Architecture: We settled on a Hybrid SWA. It’s simple, elegant, and in our internal benchmarks, it outperformed other Linear 1,116 2:53 AM • Dec 17, 2025 Rohan Paul @rohanpaul_ai China's Xiaomi released MiMo-V2-Flash, an open-source Mixture-of-Experts LLM with 309B total parameters, 15B active parameters, and a 256k context window. - Model on HuggingFace with MIT license - Beats DeepSeek-V3.2 on SWE-Bench Verified. - Hybrid Attention: 5:1 interleaved 25 2:47 AM • Dec 17, 2025 Thursday 18th December 2025Google Launches Gemini 3 Flash for Speed and Smarts This new model tops benchmarks like GPQA Diamond at 90.4% and SWE-bench at 78%, beating Gemini 2.5 Pro and even Gemini 3 Pro in spots. It shines in coding, video analysis, and tool use, all at a quarter of the Pro model's cost—$0.50 per million input tokens. Leaders like Sundar Pichai and Demis Hassabis call it the best balance of power and efficiency, now live in apps, Search, and APIs for everyday and business tasks. Developers can build fast agentic workflows with it right away.
