What if your model handled its own tuning? ⚙️ With NVIDIA TAO 7, just prompt your coding agent what you want in plain language and let it do the rest. • Agent skills plug into your coding agent and improve accuracy. • AutoML removes the guesswork from hyperparameters. LLM-guided tuning finds strong configs up to 2x faster. • Fine-tune any @huggingface CV or VLM model on local NVIDIA GPUs. • Data enhanced fine-tuning helps your agent identify why the model fails, then fix it.

NVIDIA post-trained a model from 54.41% to 93.35% with two prompts Using Codex and TAO agent skills, Cosmos 3 Nano went from 54.41% to 87.14% accuracy on 4-choice Woven Traffic Safety video QA. The agent inspected the annotations, ran the baseline, generated the LoRA config, launched training and evaluated the adapter. A second prompt launched an AutoML sweep and pushed validation accuracy to 93.35%. The first LoRA run used 8 A100s for about 30 minutes of training. The final result required 43 parallel trials across multiple A100 nodes for 19.5 hours.

"Bigger is better" may no longer be a given. This is an attempt to lift small models to frontier-level quality through training automation alone 🔬 Title: Tiny AutoScientist: Supersized Intelligence for Small Models URL: 🔬 Overview Tiny AutoScientist is an automated research system that automates the entire training and alignment process for the small models (roughly 0.8B-8B) commonly used in production, aiming to make them perform at frontier-level quality. ❓ Challenges Solved In production, latency, cost, and device constraints often push you toward small models. ・But small-model training is hyperparameter-sensitive, prone to overfitting, and tricky to handle ・So you're often forced into a painful choice between a small model that fits constraints or a large one with enough capability 💡 Methodology & How It Works ・It automatically co-optimizes your data and model-training recipes ・It self-improves both until quality converges on your objective ・It automates the full R&D loop once reserved for frontier labs, absorbing the hyperparameter sensitivity and overfitting that plague small-model training 📊 Experimental Results ・35% relative improvement over human-configured training ・Consistent gains across dataset sizes from 5K to 100K samples ・Works across multiple model architectures ・Delivers frontier-level performance in days instead of months 🌍 Use Cases It unlocks previously impractical use cases: edge deployment, on-device inference, latency-sensitive apps, and regulated industries with strict data boundaries. Since small-model tuning tends to be artisanal, automating it to beat human-configured runs carries real practical weight. #SmallModels# #AutoML#

🌳 AI is finally evolving from a tool that runs one-off experiments into something closer to a researcher itself, one that compounds knowledge across time. A new autonomous research framework grows hypotheses as a single living tree. Title: Toward Generalist Autonomous Research via Hypothesis-Tree Refinement URL: 🔍 Overview This work proposes Arbor, a framework for long-term autonomous research. Its core idea, Hypothesis-Tree Refinement, links hypotheses, the artifacts produced by experiments, the evidence gathered, and the insights distilled from them into a single persistent tree. With every experiment the tree is updated, continuously sharpening the search frontier that decides which direction to explore next. ❓ Challenges Solved Previous LLM research agents could barely manage single, isolated experiments. ・They could not maintain a big-picture strategy about which hypothesis to pursue across multiple attempts ・Lessons learned in one experiment were rarely carried into the next, so exploration started from scratch each time ・They lacked a mechanism to tell promising branches from dead ends and allocate limited compute accordingly In short, knowledge never compounded, and that was the real bottleneck. 💡 Methodology & Proposed Approach Arbor is built from two kinds of agents and a persistent tree that connects them. ・A long-lived coordinator acts as the strategist, surveying the hypothesis tree and choosing what to test next. Because it persists across sessions, it preserves long-term coherence ・Short-lived executors implement and test individual hypotheses in isolated environments, then retire once their job is done ・The hypothesis tree links hypotheses, evidence, artifacts, and insights over time, propagating reusable lessons across the whole effort This turns research from a bag of isolated experiments into a cumulative process where strategy, execution, and evidence build on each other. 🎯 Use Cases Promising applications include AutoML and automated machine learning optimization that improve through continuous experimentation, as well as automating the scientific discovery process itself. The appeal is running long stretches of trial and error strategically, without a human in the loop. 📊 Experimental Results Arbor was evaluated under an Autonomous Optimization setting across six real research tasks. ・It achieved the best held-out results on all six tasks ・It recorded over 2.5x average held-out gain compared to Codex and Claude Code ・On MLE-Bench Lite it reached 86.36% Any Medal when paired with GPT-5.5, the strongest result among the systems compared #AIAgents# #AutonomousResearch#

AUTOMATING YOUR RISK RULES! If I had to pick some of the lowest hanging fruit for traders nowadays, it’s using AI to create safeguards and automations to better control your risk. This could mean automating sizing calculations, automating how many tickers you’re allowed to trade, or how much you’re allowed to lose on a position or on the day or week or month. I know not all brokers allow you to set daily loss limits. But with AI and automation, anything is now on the table. If you haven’t done any of this, take the time to define your rules and look into ways to protect yourself. It could even be wildly creative! If your account value dips below a level, all positions are liquidated and you’re locked out of your account. Or your wife or trading buddy is emailed to lock you out and demand a post mortem review! My buddy @apaley of @riftapp did an awesome video on some creative ways you can do this:

Automattic's board put Matt Mullenweg on leave. He returned, and three directors are now out, @TechCrunch reports. The company behind @WordPress confirmed his return. It has not explained why the board put him on leave.
