  1. Stacklok's Mecatl: a Kubernetes-style cloud-native harness for agents

    Stacklok, founded by Kubernetes creators Craig McLuckie and Joe Beda, pivoted from software supply chain security to Kubernetes-based agentic infrastructure. Its open source “cloud-native harness” Mecatl, started in June, separates the agent loop from tool execution, session management and memory; the companion open source project ToolHive runs and governs MCP servers on Kubernetes. The company says its AI Gateway is not yet open sourced but is on the roadmap, with an “enterprise spine” control plane as the commercial product.

  2. OpenMontage ships as open-source agentic video production system

    OpenMontage has appeared on GitHub as a self-described first open-source, agentic video production system, bundling 12 production pipelines, 100+ tools and 700+ agent skill and production-knowledge files. It plugs into AI coding assistants such as Claude Code, Cursor, Copilot, Windsurf and Codex, letting an agent handle research, scripting, asset generation, editing and rendering using tools including Remotion, Blender, FFmpeg and Piper TTS. A local Backlot board turns the asset-generation contact sheet into an approval gate before the final render.

  3. Cognee ships v1.6.1 with Google Drive, Gmail connectors and graph visualization

    Cognee is an open-source AI memory platform that gives agents persistent long-term memory across sessions, turning documents, code and conversations into a self-hosted, searchable knowledge graph that can run locally with small models and no cloud LLM key. Per its release notes, v1.6.1 (September 24) bundles Google Drive and Gmail OAuth connectors into the SDK, streams visualization of large graphs in chunks, and moves the GLiNER installer off the event loop; v1.6.0 supports keyless memory building and retrieval. The project reports BEAM conversational-memory scores of 0.79 at 100K tokens and 0.67 at 10M tokens, while noting the two settings use different conversations, ingestion models and retrieval procedures.

  4. Omnigent open-source meta-harness orchestrates Claude Code, Codex and other agents

    Omnigent is an open-source AI agent framework and "meta-harness" that, per its project documentation, mixes Claude Code, Codex, Cursor, OpenCode, Hermes, Pi and user-defined YAML agents in the same session, with sessions that follow you between terminal, browser, phone and a macOS desktop app. The README also claims support for first-party API keys or Claude/ChatGPT subscriptions, cloud sandboxes such as Modal, Daytona, E2B and Kubernetes, and policies that pause for approval, cap spend or limit tool access, plus session sharing for teammates. The repository is currently listed on GitHub Trending for Python.

  5. text-to-cad plugin gives coding agents local CAD generation and DFM checks

    text-to-cad is an agent plugin that adds local CAD workflows: it generates 3D models as STEP, GLB, STL or 3MF from plain-language or image requests, runs design-for-manufacturing checks, produces dimensioned engineering drawings, and connects to 3D printing, sheet metal and CNC fabrication services. It installs into Claude Code, Claude Desktop, Codex, Cursor, Gemini and Grok Build — any agent supporting plugins or the skills framework — or as skills alone via npx skills add; it runs through uv and downloads the cadgen runtime on first start. Skills cover CAD, off-the-shelf STEP parts, engineering drawings, DXF, URDF/SRDF, SDF, SendCutSend pre-upload checks, DfAM printability checks, OrcaSlicer G-code and Bambu Lab printing.

  6. Diagram Design 2.5.10 adds ten more diagram layout grammars

    Diagram Design is a diagramming skill/plugin for agent hosts including Claude Code, Codex, GitHub Copilot, Factory Droid and Pi. It emits self-contained HTML + SVG with no build step, JavaScript or external image dependencies, and each visual type ships in minimal-light, minimal-dark and full-editorial variants. Creator Cathryn Lavery (LittleMight) added ten layout grammars in v2.5.10: Sankey, fishbone, Wardley map, kanban, user journey, deployment, dependency graph, UML class, story map and database schema. The skill can also read a website to match brand colors and redraw draw.io, Mermaid or Excalidraw sources at a chosen format, size and detail level; official builds come only from the repository.

  7. Sesame updates voice agents, each with its own computer

    Sesame released a fresh preview of its voice assistant in its iOS and Android apps, powered by a new voice model. Its agents are described as smarter and each has access to its own computer, letting users speak hands-free, have them plan trips or research hobbies and get an update when work is done, use tools, coordinate other agents, connect to everyday services starting with several Google apps, and attach their own MCPs. The company also laid out a three-part plan covering hand-made Japanese frames, a voice-first assistant for smart glasses it says are coming in 2027, and characters designed to be less sycophantic; developer tooling is due later this year.

  9. OpenAI’s 28-Day Push Starts With GPT-6 Speed Claims and User Skepticism

    OpenAI reportedly began a 28-day Codex and Work improvement push by increasing the default inference speed of GPT-6 Astra and GPT-6.1 Sol by about 50%, according to Tibo and coverage of the announcement. The report says the rollout drew skepticism because user tests allegedly fell short of the claimed 50 TPS and coincided with reports of ChatGPT visual ads, EU text watermarking, and changes to subscription value.

  10. OpenAI outlines a 28-day Codex and Work improvement plan

    OpenAI product and platform lead Thibault Sottiaux said the team will spend the next 28 days improving Codex and ChatGPT Work. He said users should receive a meaningful feature update each day, or a “reset,” but did not explain what the reset means or which users and quotas it would cover.

  12. AWS adds SageMaker inference-optimization skill for coding agents

    AWS introduced the aws-ai-ml skill through the Agent Toolkit for AWS, giving MCP-compatible coding agents such as Kiro, Claude Code and Codex SageMaker AI inference optimization and benchmarking expertise. The skill load-tests existing endpoints and reports measured throughput, latency percentiles and concurrency, ranks instance types for models stored in S3, in SageMaker JumpStart or on Hugging Face Hub, compares two benchmark runs, and generates runnable SageMaker Python SDK v3 code. It can be installed locally via an npx command or used in a preconfigured image inside a private Amazon SageMaker Studio JupyterLab space.

  13. OpenAI to watermark ChatGPT and Codex text in the EU, off by default elsewhere

    OpenAI said it will add an invisible textGrain watermark to eligible ChatGPT and Codex text in the European Union over the coming weeks for users on all plans, to comply with the EU AI Act's transparency rules; API customers worldwide can opt in starting today, with watermarking off by default. The method embeds a statistical signal in the model's word choices rather than visible characters, and OpenAI published a technical report co-written with University of Pennsylvania and Yale researchers, saying it saw no meaningful benchmark differences with watermarking on. Detector access is initially limited to approved researchers and expert organizations, and OpenAI says it plans to open-source the technology, while cautioning that detection falls to about 80% on 200-token passages and weakens sharply after synonym edits.

  14. OpenAI Promises 28 Days of Releases or Resets Amid User Trust Concerns

    A 36Kr report says Tibo announced that OpenAI would focus on simpler products, greater efficiency, breakthrough features, and new models, while promising 28 consecutive days of releases or resets. The report frames the pledge as a response to user frustration over tighter usage limits, slower models, and limited day-to-day impact from recent DevDay announcements.

  15. Qwen3.8 27B sums big numbers in words, hitting 167/169 with reasoning on

    Simon Willison re-ran an experiment Colin Frasier first tried two years ago with GPT-4o: have a model compute large sums but return the answer in words. He ran it on local hardware (a DGX Spark), using a Codex Remote session (GPT-6 Astra) to write and execute the test with Qwen3.8-27B-Q4_K_M.gguf. With reasoning disabled he sampled 30 attempts per cell; with reasoning enabled each run took so long that he used one sample per pair, and the model got 167 of 169 attempts right.
