AIVerizon shares fell about 7% and T-Mobile fell 12% on Friday after SpaceX announced a deal to buy a nationwide spectrum portfolio from Grain Management to expand Starlink into mobile service. The portfolio covers up to 14 megahertz of paired spectrum in the 800 MHz band. AT&T fell about 10%, while SpaceX stock rose about 1%.

AIRohit Prasad, a longtime Amazon AI executive who helped build Alexa, will lead Boston Dynamics as the robotics company prepares to manufacture humanoid robots at scale. The source does not give further details on the appointment or production timeline.

AIMeta's Muse AI agent has millions of users and can handle tasks from refunds to insurance shopping. Its broad access to personal data has already led to some unnerving mistakes, according to Fast Company.

AILangChain's Managed Deep Agents v0.9 adds a reactions attribute for Slack channels that accepts either an emoji string or a callable returning one. The article shows a function that returns a bug emoji when a message contains "broken" and eyes otherwise. It also shows a TypeSafe Classifier that picks from a seven-emoji vocabulary and falls back to eyes below 25% confidence.

AIAnthropic planted 70 bugs in a 116k-line codebase and tested two approaches over three runs. A single agent found 14, 15 and 27 bugs, while a workflow found 66 bugs in each run.

AIAnthropic says dynamic workflows are powerful but can use many tokens, so users should start with a scoped task and increase complexity gradually. It points to the /claude-api managed-agents-onboard bug-hunter command in Claude Code and to templates at

AIPerplexity Developers says its new cookbook builds a browser agent that sends a screenshot and questions to pplx-decider-v1.1-27b through the Decisions API, which accepts text and image inputs. The developer's code converts the returned probabilities into clicks, scrolls, and stops.

AIReplit's X account shares a showcase of TikTok Ads MCP, which runs TikTok Ads from Replit. The post is a broadcast link with no further details on features, pricing, or availability.

AIFactory says it is acquiring Mentlio (YC S26), a startup building in-harness model routing, context compression, and AI usage measurement to optimize cost and quality. The founders, Ashank Shah and Ahmet Demirbas, will join Factory to bring this work into its autonomous software engineering platform for large enterprises.

AIAi2 says its old scheduler made every scheduled workload eventually run at HIGH priority. Researchers kept idle jobs running to reserve GPUs for experiments, because the incentives rewarded holding capacity even with no active work.

AIAi2 reports that over a 30-day test of its new scheduler, teams received 98% of the GPU hours they were owed, based on actual demand. Cluster occupancy stayed at 98%, and spare capacity went to interruptible work without drawing down team budgets.

AIMeta spent heavily on Anthropic's Claude models, with internal use reaching up to 60,000 employees and a projected $10 billion yearly spend, according to The Algorithmic Bridge. The author says Meta then released Muse Spark, which scored 52 on the Artificial Analysis intelligence benchmark, on par with Claude Opus 4.6.

AIAi2's AI Infrastructure team replaced its priority-based scheduler for GPU clusters with GPU time budgets, hierarchical fair-share allocation, and a time-slicing contract. The team says the change moved debates over how much GPU time each research project deserves from case-by-case operational decisions into a transparent budgeting process. The clusters range from 88 to 1024 GPUs across NVIDIA H100, B200, and B300 hardware, and serve about 150 internal researchers.

AIPostman describes the architecture behind Agent Mode, its AI agent for API testing, documentation, discovery, and implementation. The post covers limiting tools per task, using schema-based queries, building purpose-shaped context handlers, and running on Amazon Bedrock with cross-Region inference and prompt caching. Postman reports that tool-selection errors rose once the visible toolset exceeded about 40 tools.

Why it matters: The post shows concrete patterns for tool scoping, context handling, and Bedrock routing and caching, which apply to any team moving an agent past a prototype.

AIAmazon Bedrock Managed Agents, powered by OpenAI, entered public preview, and OpenAI's GPT-6 Astra, GPT-6.1 Sol, and GPT-6.1 Luna became generally available on Amazon Bedrock. AWS also released Strands Decider 2B, a 2B-parameter open source decision model that answers in about 115ms locally, and said the Strands harness uses 28 percent fewer tokens than popular harnesses while matching their accuracy.

AIAi2's AI Infrastructure team replaced its priority-based GPU cluster scheduler with a system using GPU time budgets, hierarchical fair-share allocation, and a time-slicing contract. The team says the change turns decisions about how much GPU time each research project receives into a transparent administrative budgeting process. Its clusters, which range from 88 to 1024 GPUs including H100, B200, and B300 units, serve about 150 researchers facing demand two to three times available capacity.

AIOpenAI's research leaders say they parted ways with Jasmine, Mikita, and Tomek after an investigation found they violated policies on handling sensitive information. The company says the decision was not about raising safety concerns and that it is finalizing contracts with third-party safety assessors, with details to follow in the coming weeks.

AIOpenAI says Codex on Windows now has a new sandbox mode built on Microsoft's Execution Containers (MXC), offering faster setup, stronger network enforcement, and granular file access controls. The mode requires a compatible Windows 11 device. Background from Microsoft's announcement says MXC is now generally available on Windows 11, keeping agents within boundaries the operating system enforces.

AIBaseten explains how to decide which layers of a model can run in 4-bit NVFP4 without losing needed information. The post compares architecture-based heuristics, isolated-layer sensitivity scoring, and SaturationQuant, which accounts for other quantized layers. It also covers calibration with representative data and block-level scales of 16 values.

Why it matters: The post explains how to choose which layers run at NVFP4 precision using heuristics, sensitivity scoring, and saturation-aware scoring, with clear calibration steps.

AIGuizang says he turned his workflow into a Grok bot that users can install with one click. The bot runs on Grok's cloud virtual machine to collect content, write code, and render a daily morning AI news video without using a local computer.

AIArena's weekly update says Nano Banana 2.1 ranked in the top six across three Image Arena modes, with #4 in Multi-Image Edit at 1431 points. Mistral Large 4 placed #43 overall in Agent Arena, 11 spots above Mistral Medium 3.5, and Claude Haiku 5.5 (High) landed #30 in Code Arena WebDev at 1587 points, priced at $0.10/$0.50 per 1M input/output tokens. The post also introduces Arena's Alignment Index and announces a $200M Series B at a $3.1B valuation.

AIPerplexity says its Computer tool created Alexandria, a free, source-backed encyclopedia with 66,574 entries, for $25,000 in credits (2.5 million). Computer scanned and synthesized 348,980 sources to build it, and will maintain the site at alexandria.pplx.app.

AIBoris Power, who owns the OpenAI account, posted only the word "Wow!" with no details. Background from a separate post says the integer multiplication problem #109 witness value κ rose to 2⁻¹⁰·⁵⁴⁷ (about 6.6857 × 10⁻⁴), past the 2⁻¹¹ threshold. The author notes gains are now fractional and a major breakthrough is still needed.

AIAnthropic claims Chinese AI developers used fraudulent accounts and proxy networks to extract reasoning data from its flagship model, Claude. The company says some firms used Claude as a covert back end for their own apps. A joint advisory from the NSA, FBI and CISA last month, and US Treasury Secretary Scott Bessent's July warning about large-scale distillation, add to the allegations.
