Agents

AIGoogle DevRel's James O'Reilly explains how Antigravity Agent Plugins expose local MCP server tools to the model, either eagerly as top-level functions or lazily through a call_mcp_tool proxy. Eager loading, set via "eager": true in mcp_config.json, avoids the discovery turn but adds fixed per-turn token overhead that can degrade reasoning with 100+ tools. Lazy loading is the plugin default and keeps baseline token use low, at the cost of an extra proxy hop and a higher chance of JSON quoting errors.

AIDatabricks announced general availability of on-behalf-of-user (OBO) authorization for Databricks Apps, letting apps act with the signed-in user's identity so Unity Catalog enforces that user's row filters and column masks. Developers can request narrow API scopes such as sql:restricted-query, which allows only read-only SQL queries, while apps keep a dedicated service principal for app-owned operations.

AIMicrosoft Research Asia has open-sourced Agent Lightning v1.0, a roughly 3,500-line agentic RL framework that trains the same agent harness used in deployment. In an end-to-end coding agent pipeline, Qwen3.5-9B rose from 41.8% to 56.4% Pass@1 on SWE-bench Verified using about 6,000 training samples. The framework runs agents as standard Kubernetes jobs without paid commercial sandbox services.

Why it matters: The source shows how training with the deployed agent harness avoids rebuilding agents, and reports concrete SWE-bench Verified gains from about 6,000 samples.

AINVIDIA describes using digital twins and AI agents to validate changes to AI factory infrastructure, which combines GPUs, CPUs, switches, DPUs, and SuperNICs with schedulers, orchestration services, security controls, and a fast-changing software stack. The source frames the challenge as confirming that hardware, software, and policies work together for target workloads before deployment. The available excerpt does not give further detail on specific tools or results.

AIQlik built Qlik Answers, a natural-language assistant that returns sourced answers from knowledge bases, analytics apps, glossaries, and documents, using Amazon Bedrock for model access. The system routes each question through specialist agents and retrieval on Amazon OpenSearch Service, with Amazon Bedrock Guardrails applied to every request and response. Qlik serves more than 40,000 customers across regions, using Amazon SageMaker AI as an in-Region fallback when models are not yet available on Bedrock.

AIThe AWS Machine Learning Blog describes an automated remediation workflow that acts on AWS DevOps Agent investigation results. Amazon EventBridge triggers a Lambda durable function that uses Amazon Bedrock to propose fixes from an allowlist of tools, running read-only actions autonomously and pausing for human approval before infrastructure changes. The post demonstrates the flow with a Lambda function whose 3-second timeout is raised to 30 seconds after a single approval.

AILucas Beyer praises Reality Check, a new leaderboard for benchmarking VLA and related robot manipulation models. Half of its tasks are fully open, while the other half are held out to detect benchmaxxing by future model versions. The companion post from Nicolas Keller describes the launch as the first public robot manipulation benchmark, built on 14,400 real-world rollouts across four models.

AIGitHub has made local sandboxing for GitHub Copilot generally available in GitHub Copilot CLI, the GitHub Copilot app, and VS Code sessions using Agent Host. Sandboxes restrict the filesystem, network, and credentials that Copilot-initiated tools and commands can access, based on developer or organization policies. The feature is powered by Microsoft eXecution Container (MXC), supports Windows, macOS, and Linux, and is included at no additional cost.

AIAWS ran a six-week program pairing non-engineering professionals with mentors and tools like Amazon Bedrock AgentCore and the Strands Agents SDK to build working AI prototypes. Four participants with no engineering background built WealthWise, a multi-agent financial advisory tool with five agents on Amazon Nova models, which won first place. The article says participants who completed the phased program retained three times more practical skills than those in two-day intensive formats.

AIStacklok, founded by Kubernetes creators Craig McLuckie and Joe Beda, has released Mecatl, an open source cloud-native harness for coding agents on GitHub. Mecatl keeps the agent loop separate from the client, model provider, state store, and execution environment, and moves tool calling, session management, and memory into manageable systems. The article also covers ToolHive, an MCP platform, and an AI Gateway that is not yet open sourced, with a commercial enterprise control plane tying the pieces together.

AIMistral Large 4 scored highest on AutomationBench, a benchmark of 657 business workflows across simulated workplace apps including Gmail, Google Sheets, Slack, and Salesforce. It finished ahead of Kimi K3, MiMo-V2.6-Pro, and DeepSeek V4 Pro.

AIAllie K. Miller outlines three agent workflows that work like an executive assistant and need only calendar access. The agent screens junk signups and sends only high-signal email recaps, routes speaking and advising inquiries with org research and a worth-your-time verdict, and builds a living CRM from forwarded emails that flags relevant contacts for follow-up.

AILauren Tan recommends new Grok Bot users first connect regularly used apps such as calendar, Slack, issue tracker, CRM, and Google Drive so the bot has work context and needed tools. She advises starting with one primary bot before adding specialized bots, which can be designed or chosen from the bot marketplace.

AIGoogle introduced Playground, an experimental platform where users can create, play, and share custom games by describing them through text prompts without coding. The platform is browser-based, supports multiplayer and leaderboards in select genres, and launches today for U.S. users aged 18 and older, with creation access rolling out by Google AI subscription tier. A planned integration with Unity Spark will add more advanced 3D and mechanics for dedicated creators, and Unity Spark is currently in testing with a closed beta coming soon.

AIThe main post says the platform is starting to compete for the personal-agent entry point, with a hard fight expected. The quoted post claims Grok bot will use the best model for each task, drawing on Grok 4.7 or 4.6 and external services such as Opus 5.5, Midjourney, and Suno to build content or execute tasks.

AIDeepal Automobile officially announced the 2027 Deepal L06, positioned as a long-range magnetorheological AI sedan equipped with two "lobsters," namely an AI Agent and an AI Box. Chairman Deng Chenghao said the two systems let owners state their intent in a single sentence, though no launch date has been disclosed.

AIOpenAI's Dots, an always-on AI agent accessed through ChatGPT, can run recurring tasks and message users proactively, with the company offering it behind a $100-a-month subscription. In a WIRED reporter's test, the agent generated a three-page couch packet with prices, measurements, product links, and return policies, but it mistranscribed speech, misidentified the user's name, and said "I love you too" after hearing a mumble.

AIThe Sequence's Issue 946 covers OpenAI's September 29 DevDay announcements and Google's September 30 introduction of Gemini 4 Argon. The newsletter argues that AI competition is shifting toward completed workflows, where cost, context, and supervision determine what models can finish.

AIWhat I like the most about this new architect is its ability to proactively look for improvements and come back with a drafted proposal that’s already validated. Think about that for a second. The architect looks at your agents, how they work, their conversations, and comes back to you with a plan to make them better.

AIElon Musk says SpaceX will use the best back-end model for each task on Grok Bot, including Claude Opus 5.5, MidJourney, Suno, and other leading APIs. Matt Shumer calls this extremely good news for bot users.

AIZeptap is now live on Product Hunt as a Mac app that lets AI agents use an iPhone the way a person would. The team describes it as computer use for iPhone and is offering a free 7-day launch license key to those who DM them.

AIElon Musk says SpaceX will use the best back-end model for each task, including Claude Opus 5.5, Midjourney, Suno, and other leading APIs. The main post is only an eye emoji, so its own content adds nothing beyond the quoted note about Grok's routing.

AIGrok Bot will now use the best backend model for each task, including Claude Opus 5.5, MidJourney, Suno, and other leading APIs. The change is framed as choosing whatever is most likely to produce the best outcome for users.

AIRadisson Hotel Group partnered with Accenture to build a ChatGPT plugin using OpenAI technology. The plugin helps travelers find, compare, and book hotels while planning their trips.

AITeknium says Hermes was never intended to be just a personal assistant that reads emails, but the most powerful AI agent for all users. He says consumers are one audience, while scientists, cybersecurity engineers, developers, knowledge workers, and creatives are also intended users.

AITeknium says a plugin from @altryne's current project should be added to the plugin catalog. The post is a brief endorsement and does not describe the plugin's functions. Background from @tonysimons_ says Hermes is getting a local video editor for editing user footage with 42 FFmpeg scripts and no cloud or API key required.

AILangChain revamped skills support in Deep Agents with three changes: tools bound to a skill load only when the agent reads that skill, pinned skills are loaded before the next model call when a user requests them, and long-running threads can pick up new or changed skills without restarting. Each skill is a folder with a SKILL.md file, and only its name and description are in context until the agent reads the full instructions.

AIEvery launched the Every Agent, a Slack-based agentic coworker whose token costs it passes on to customers without markup. Engineer Paridhi Agarwal explains how she made the agent more token-efficient, and the newsletter says the company moved from personal agents to a single shared company agent.
