Reactive Optimizers

The paper introduces OPAL, a reactive optimizer that employs a pretrained language‑model agent to monitor training dynamics and modify optimizer code on the fly. OPAL can alter update rules, schedules, learning‑rate schedules, optimizer structure, numerical precision, and momentum for individual parameter groups without prior meta‑training or cross‑run memory. Experiments on language modeling and image generation show that OPAL matches or surpasses fixed recipes, adapts to data corruption, and reduces over‑fitting, while the authors also discuss its computational cost and implementation details.

Harnessing Language Models as Optimization Modeling Agents

The paper introduces two lightweight inference harnesses, OPTICYCLE and OPTISTATE, designed to enable large language models to translate natural-language optimization problems into solver programs without additional training. Evaluated across nine benchmarks and 11 Qwen variants (0.6B–27B parameters), the harnesses consistently improve macro accuracy, with execution-guided revision boosting performance by up to 49.46 percentage points. Despite their simplicity, both harnesses outperform six adapted agentic workflows and four post-trained optimization models of comparable size, though the benefit of explicit formulation state varies by model.

RSI-Opt: Recursive Self-Improvement Optimizer Agents For Model Training

RSI-Opt introduces Recursive Self-Improvement Optimizer Agents that evolve their own training policies by accumulating knowledge from previous runs, including prompts, playbooks, optimizer code, and decision cadences. A meta‑agent rewrites and archives these policies, enabling reusable procedures and code that adapt to new tasks. Across multiple generations and tasks, RSI‑Opt improves optimizer performance, achieving higher z‑scores on evolution suites, better cross‑model transfer, and significant error reductions on PDE benchmarks compared to fixed‑prompt baselines.

VISA: Agentic Self-Evolving Data Synthesis for Multimodal Instruction Following

VISA (Visual Instruction Synthesis Agent) is an agentic framework that transforms multimodal instruction synthesis into a self‑evolving loop. Each cycle analyzes images to filter constraints, samples new constraint sets, generates candidate instructions, and verifies them using executable tools and large language model judges. Failed samples trigger diagnostic recovery, while accepted samples are evaluated against the target model to estimate difficulty, with all feedback written back to memory to adapt future rounds and provide reward signals for reinforcement learning.

How to Train Your Little Dragon: Teaching a Small Language Model to Construct and Refine GPU Optimization Scripts

The paper introduces HOW TO TRAIN YOUR LITTLE DRAGON, a method for teaching a small language model to generate and refine GPU optimization scripts. Using a compact, lossless representation of compiler traces, the authors train the model on 108,594 examples derived from TVM MetaSchedule, first with supervised fine‑tuning and then with reinforcement learning that rewards correctness and performance. After training, an 8‑billion‑parameter model achieves over 91% correctness in both construction and refinement tasks and outperforms several much larger LLMs on kernel performance.

Can Generalist Agents Automate Data Curation?

arXiv:2606. 04261v1 Announce Type: new Abstract: Curating training data is among the most consequential yet labor-intensive parts of modern AI development: practitioners iteratively propose, implement, evaluate, and revise data policies against noisy benchmark feedback.

FlashNext-RL: A System Optimization Study for Long-Horizon Agentic RL of Qwen3.8-Flash-Next

FlashNext‑RL is a model‑specific reinforcement learning training framework designed for the Qwen3.8‑Flash‑Next language model. It optimizes BF16 training of the full 48‑layer model on a single 8×B200 node by freezing early layers, offloading host memory, and tuning kernels for mixture‑of‑experts, sparse attention, and gated residual streams. The optimizations raise non‑padding training throughput from ~395 tokens/s/GPU to 4,438 tokens/s/GPU and enable a live software‑engineering RL run with 1,024 rollouts and a 131,072‑token context, completing iterations in about 22.4 minutes.
