Configure the ChatGPT desktop app with Amazon Bedrock in AWS GovCloud (US)
AWS explains how to configure the ChatGPT desktop app so Codex routes model requests through Amazon Bedrock Mantle in us-gov-west-1. The walkthrough combines API-mode sign-in, administrator-controlled requirements.toml, config.toml, a named AWS profile, and network restrictions that permit the approved Bedrock endpoint. It covers authentication precedence, provider verification, troubleshooting, and rollback, while emphasizing that organizations must review the deployment through their own security authorization process.

SoMark’s 1.3B OXR tops three document parsing benchmarks with recursive self-improvement
SoMark has open-sourced OXR, a 1.3B document parsing model that reportedly scores 97.18 on OmniDocBench, 87.84 on olmOCR-Bench, and 87.76 on DocParsingBench, ranking first on all three. Its recursive self-improvement process identifies errors and uncertain predictions, clusters their causes, and generates targeted training data without new manual annotations. OXR separates layout analysis from recognition and reading order prediction, reportedly parsing 100 pages in 101.0 seconds on one RTX PRO 6000; code, weights, evaluation procedures, and a free API requiring no registration or key are available.

How Agentic AI Helps Search for Extraterrestrial Signals at the Allen Telescope Array
Breakthrough Listen and the SETI Institute are using agentic AI at the Allen Telescope Array to steer antennas, correct incoming data and apply AI models through natural language requests. NVIDIA Holoscan and related tools support processing 2.4 terabits per second on NVIDIA RTX PRO 6000 Blackwell GPUs, with inference running on premises. The pipeline has already achieved what the source describes as the first real-time AI detection of a pulsar in the Crab Nebula.

ForgeKernel goes open source after outperforming DeepSeek’s FlashMLA kernel on B200
QbitAI reports that ForgeKernel, an autonomous kernel-generation system from ModelBest, was open-sourced after a 22.5-hour livestream optimizing DeepSeek-V4.1’s FlashMLA Prefill kernel on an NVIDIA B200. Given mathematical definitions and hardware constraints without DeepSeek’s implementation, it completed 42 iterations and reached 472 microseconds versus FlashMLA’s 518 microseconds, a reported 9.8% speedup. The system separates architecture planning from implementation, retains experimentally validated hardware knowledge, and iteratively competes against its own best versions.

Managing Amazon Bedrock costs end to end: A playbook for FinOps and platform teams
AWS outlines a five-stage operating model for managing Amazon Bedrock costs through attribution, observability, budget enforcement, optimization, and recurring reviews. The guide explains per-user attribution behind shared gateways and compares monitoring, asynchronous IAM enforcement, and synchronous gateway blocking. It also describes using workload telemetry to guide model routing and prompt caching, while distinguishing cost control from measuring whether an agent delivers worthwhile outcomes.
