A r/LocalLLaMA post that reached 92 points and 25 comments spotlighted Covenant-72B as a 72B-parameter model trained from scratch by 20+ participants through decentralized infrastructure on the Bittensor blockchain. The most credible story here is not an unsupported performance victory, but a concrete demonstration of permissionless collaborative pre-training, SparseLoCo-based communication reduction, Apache 2.0 licensing, and a separate chat-tuned variant.

RSS FeedMistral AI said on March 16, 2026 that it is entering a strategic partnership with NVIDIA to co-develop frontier open-source AI models. A linked Mistral post says the effort begins with Mistral joining the NVIDIA Nemotron Coalition as a founding member and contributing large-scale model development plus multimodal capabilities.
On March 16, 2026, a r/LocalLLaMA link to Mistral Small 4 reached 504 points and 196 comments. The Hugging Face model card describes a 119B MoE with 4 active experts, 256k context, multimodal input, and per-request reasoning control.
Sebastian Raschka's LLM Architecture Gallery drew attention on HN for turning recent model families into comparable diagrams, making dense, MoE, and hybrid design choices easier to scan in one place.
A high-signal LocalLLaMA thread on March 15, 2026 focused on a license swap for NVIDIA’s Nemotron model family. Comparing the current NVIDIA Nemotron Model License with the older Open Model License shows why the community reacted: the old guardrail-termination clause and Trustworthy AI cross-reference are no longer present, while the newer text leans on a simpler NOTICE-style attribution structure.
A March 15, 2026 LocalLLaMA post pointed to Hugging Face model-card commits and NVIDIA license pages showing Nemotron Super 3 models moving from the older NVIDIA Open Model License text to the newer NVIDIA Nemotron Open Model License.
A post in r/MachineLearning argues that duplicating a specific seven-layer block inside Qwen2-72B improved benchmark performance without changing any weights.
NVIDIA AI Developer introduced Nemotron 3 Super on March 11, 2026 as an open 120B-parameter hybrid MoE model with 12B active parameters and a native 1M-token context window. NVIDIA says the model targets agentic workloads with up to 5x higher throughput than the previous Nemotron Super model.
Microsoft says Fireworks AI is now part of Microsoft Foundry, bringing high-performance, low-latency open-model inference to Azure. The launch emphasizes day-zero access to leading open models, custom-model deployment, and enterprise controls in one place.
A high-scoring LocalLLaMA thread surfaced Sarvam AI's release of two Apache 2.0 reasoning models, Sarvam 30B and Sarvam 105B. The company says both were trained from scratch in India, use Mixture-of-Experts designs, and target reasoning, coding, agentic workflows, and Indian-language performance.
Mistral has launched Mistral 3, a new open multimodal family with dense 14B, 8B, and 3B models under Apache 2.0, plus a larger Mistral Large 3. The company says the lineup was trained from scratch and tuned for both Blackwell NVL72 systems and single-node 8xA100 or 8xH100 deployments.
NVIDIA’s January 5, 2026 update expands its open AI stack across Nemotron, Cosmos, Alpamayo, Isaac GR00T and Clara. The company paired model releases with large-scale datasets and deployment pathways to accelerate production AI adoption across industries.
