AllenAI Open Instruct Tulu 3 Post-Training with SFT, DPO, RLVR, GRPO, and Verifier-Based Evaluation

MarkTechPost 2 months ago 44

AllenAI’s tutorial shows how to run an end-to-end post-training pipeline for a compact instruction-tuned language model on the Open Instruct framework, covering SFT, DPO, and GRPO with verifier-based evaluation for math answers. It adapts the original multi-GPU Tulu 3 setup to fit within a 16 GB runtime. As a result, the workflow keeps Open Instruct’s optimization logic while swapping out distributed training pieces (vLLM/Ray/DeepSpeed/async queues) for lightweight Hugging Face and PyTorch code suited to Colab.

Code that passes every test can still break the next AI agent that touches it

The New Stack 2 months ago 25

Google promoted Go as a language that gives AI coding agents guardrails by relying on a small syntax, static typing, and integrated tooling, while noting that these checks still can’t verify correct business logic or data access. A June 2026 study analyzed 278,790 inline review conversations and found human reviewers required 11.8% more review rounds for agent-written code than for human-written code. As a result, even code that passes tests can still break the next AI agent’s work, shifting more maintenance and review burden to human developers.

AI Generated 3D Models Flood Market, But Almost No One Is Buying Them

404 Media 2 months ago 44

CGTrader found that AI-generated 3D models now make up one in six uploads on its marketplace but generate minimal sales. AI-generated assets account for $1 out of $90 in revenue, and 4% of 3D-printing buyers said AI works well. CGTrader says the mismatch between upload volume and demand is pushing it to prioritize quality and performance signals in discovery and ranking rather than raw quantity.

Coding agents ignore open source contribution guidelines, researchers find.

The New Stack 2 months ago 25

Researchers at Peking University found autonomous coding agents often ignore open-source contribution rules and fail to handle AI-banned repositories correctly. In tests across four frontier models on 106 issues from 49 repositories, the agents almost never proactively retrieved contribution rules and never refused to contribute to AI-banned projects even with reminders. Maintainers are pushed toward external controls like adding policy discovery to tooling, blocking PRs via allowed tools, routing AI-flagged changes for heavier review, and relying on standard SDLC checks rather than expecting agents to self-police.

Pakistani Judges Give Their Verdict on JudgeGPT

IEEE Spectrum 2 months ago 21

Pakistan ran a large trial of JudgeGPT, a custom generative-AI tool for judges, and found it increased the number of cases resolved without an obvious drop in judgement quality. Trained judges were associated with a 6.3% rise in resolved cases after JudgeGPT use. The results led to emphasis on retrieval-based source linking and targeted training to improve accuracy and reduce inappropriate reliance on the tool.

Empty shelves or lost keys? Recall is the bottleneck for parametric factuality

Google Research 2 months ago 47

Knowledge profiling found that many factual mistakes in frontier LLMs are recall failures (encoded facts not reliably accessible) rather than encoding failures (facts not encoded). 95–98% of facts were encoded in Gemini-3-Pro and GPT-5, yet direct recall failed on 26–34% of facts. The implication is a shift toward interventions that improve knowledge utilization (including thinking/recovery) instead of primarily scaling to add missing knowledge.

Xiaomi’s MiLM Plus Releases PROVE: Perception-Aligned Object Removal Metrics RC-S and RC-T With a Real-World Video Benchmark

MarkTechPost 2 months ago 1

Xiaomi’s MiLM Plus released PROVE, a tool meant to better evaluate object removal models when existing metrics mis-rank outputs because erasure is one-to-many. RC-S reaches 0.59 average Kendall’s τ against human rankings, versus 0.26 for ReMOVE and 0.16 for CFD. PROVE introduces RC-S and RC-T plus PROVE-Bench and is published as an Apache 2.0 PyTorch repo so teams can score edits without reference videos and use the metrics for CI or tuning.
