NVIDIA AI Unveils ProRL Agent: A Decoupled Rollout-as-a-Service Infrastructure for Reinforcement Learning of Multi-Turn LLM Agents at Scale

By Asif Razzaq

70 score

AI Analysis

NVIDIA researchers introduced ProRL Agent, a scalable 'Rollout-as-a-Service' infrastructure that decouples agentic rollout orchestration from the RL training loop for multi-turn LLM agents. The system addresses resource conflicts between I/O-intensive environment interactions and GPU-intensive policy updates that bottleneck agent development.

NVIDIA researchers introduced ProRL AGENT, a scalable infrastructure designed for reinforcement learning (RL) training of multi-turn LLM agents. By adopting a ‘Rollout-as-a-Service’ philosophy, the system decouples agentic rollout orchestration from the training loop. This architectural shift addresses the inherent resource conflicts between I/O-intensive environment interactions and GPU-intensive policy updates that currently bottleneck agent development.

[AINews] H100 prices are melting UP

By Unknown

68 score

AI Analysis

H100 GPU rental prices have surged significantly since December 2025, reversing the prior depreciation trend. The price increase is attributed to a general chip shortage, the reasoning model/agent inflection, and improved software making the 4-year-old chip more useful than ever.

At GTC 2022, NVIDIA announced the Hopper architecture and the first H100s started rolling out in October of that year. 2 years later, in October 2024, we published a popular piece on the H100 rental price depreciation cycle, which we had observed to be a going faster than previous cycles and theorized that it was a slight bubble burst dynamic due to temporarily inflated demand. While true for the time (bottoming out after the DeepSeek R1 shock, it did not last; since December 2025 the H100 renta

‘Our assumptions are broken’: how fraudulent church data revealed AI’s threat to polling

By Sinéad Campbell

55 score

AI Analysis

Fraudulent survey data generated by AI tools was discovered to have corrupted polling and research data, including a widely cited report on church attendance in Britain. Experts warn that paid survey participants are using automated AI tools at scale to generate unreliable responses, threatening the integrity of polling.

AI Analysis

Researchers find that AI-generated political deepfakes, including fabricated people in military contexts, are growing in influence and generating revenue even when viewers know the content is fake. Sexualized AI-generated women in camouflage have built significant audiences and serve as effective propaganda.

AI Analysis

Two in five Australian GPs now use AI scribes to record patient consultations, raising questions about consent, data privacy, and whether the technology improves or hinders the doctor-patient relationship. Advocates warn the technology may trade genuine care for administrative convenience.

Some doctors argue it allows them to better connect with patients, but advocates warn the AI technology risks the oppositeGet our breaking news email, free app or daily news podcastWhen a patient walks into a GP’s office in Australia today, the doctor may begin with a question: “Do you give consent to use an AI scribe to record our conversation?”That’s what is supposed to happen, at least.
