AINVIDIA publishes a GR00T N2 checkpoint, step 18200, as a native split ONNX export on Hugging Face for SSD pickup and placement. The model trained on 196 pickup and 149 placement episodes, with 310 training and 35 validation episodes, and one shared set of graphs serves both tasks through a host-side task selector. The package is not a TensorRT engine or a robot-ready policy, and NVIDIA does not assert full ONNX/eager numerical parity or robot success rates.

AIAi2 says its Olmo Hybrid paper shows a model combining transformer attention with linear recurrent layers reached the same MMLU accuracy as Olmo 3 7B using 49% fewer training tokens. The lab says a next Olmo model with a hybrid mixture-of-experts architecture is in pre-training, and that it released Olmo-core 3 for training large mixture-of-experts models. Ai2 also released AstaBrief, an open-weights model that generates cited reports from research questions and retrieved literature.

AIPrime Intellect says Prime Agent is now open source and that its Rust rewrite is available today. The full blog post covers verification loops, multi-agent orchestration, and performance experiments.

AIPrime Intellect says users can update their Prime Agent by running the command prime-agent update. The post links to the project's GitHub repository, PrimeIntellect-ai/prime-agent.

AISierra has published a draft of the Personal Agent Protocol, known as Poppy, and named 35 additional design partners, including Adyen, Bank of America, Mastercard, OpenAI, PayPal, and Visa. Under the protocol, companies publish a /.well-known/poppy.json discovery file, and personal agents start sessions, identify themselves, and sign in through OAuth with session tokens limited to approved access. The company says the draft will be followed by design workshops and a reference implementation over the next month.

Why it matters: The draft specifies how personal agents identify themselves, obtain customer-approved access, and work with company websites, APIs, or agents, which helps readers assess its practical effect on agent-driven transactions.

AIQwen has released its Turbo image model with open weights, giving image app builders an option to run it in-house instead of relying on hosted API pricing. The post does not specify model size, benchmarks, or pricing.

AICloudflare has published a new model called clef-omni on Hugging Face, according to a post from Julien Chaumond, who owns the account. The post links to the model page but gives no further details about its size, capabilities, or benchmarks.

AIMicrosoft says the full Word, Excel, and PowerPoint apps are now rolling out to the Copilot app in Frontier. Users can create, edit, and collaborate on documents in one connected workspace, with branded templates and version history. The workspace also offers a library of frontier models, with an Auto router that picks a model for each task.

AIOpenAI's developer account announces composer predictions in Codex, which suggest a user's next message based on the conversation and how the user writes. During the beta, the feature is included at no additional cost for eligible Pro users.

AISuno says the wavetable synth, musical typing keyboard, and expanded plugin views in Suno Studio can now float anywhere on screen, including a second monitor. Studio is included with Premier.

AIAnthropic has launched Cyber Mission, a long-term program to protect critical infrastructure and open-source software from cyberattacks. A free OSS AI scanner will regularly check open-source projects, flag and explain vulnerabilities, and suggest patches. Anthropic expects over 90 percent accuracy, but reports ship without human review and may contain errors.

AIMistral AI has released LIDstral-Arabic, a fast classifier that identifies Modern Standard Arabic, Arabic dialects, and non-Arabic languages written in Arabic script across 51 classes. On Moroccan Darija, it scores 88.67% F1, versus 72.65% for LahjatBERT ALDi CL and 71.28% for GlotLID v3, across 84,870 evaluation examples. The model runs on CPU and is available from a private Hugging Face repository under Apache 2.0.

AIQwen has published Qwen-Image-2.1-Turbo on Hugging Face, an accelerated checkpoint of Qwen-Image-2.1 for text-to-image generation and image editing with 8 denoising steps. The checkpoint uses the same 7B visual generation architecture, loads directly with QwenImage21Pipeline in Diffusers, and includes its recommended sampling schedule. It defaults to CFG=1 and uses prefix KV caching to reuse text and reference-image context across steps.

AIGoogle AI announces that SynthID.com is now available globally in English for verifying AI-generated images, video, and audio. The post also lists Nano Banana 2.1, EmbeddingGemma 2, Gemma 4 with BOTANIC-1, a Gemini business agent, and Guided Vision in Gemini Live.

AITencent has open-sourced Youtu-Parsing-Omni, a 5B-parameter omni-modal model that outputs a single structured JSON covering layout, text, tables, formulas, ASR, OCR, and video segments. It scores 96.96 Overall on OmniDocBench, the highest among the compared models, and ships with weights on Hugging Face, a vLLM plugin, and inference examples.

AINVIDIA has released a deployment model for Agile One S SSD pickup, based on GR00T N1.7 checkpoint 58000 and using three cameras: ego, left wrist, and right wrist. The repository republishes ONNX graphs, external tensor files, and two existing TensorRT BF16 engines without retraining or re-export, and the original export reported a numerical warning that full FP32, node, and BF16 parity did not pass all tolerances. The files are not a certified robot deployment or safety qualification.

AINVIDIA published the Agile One S Walk GR00T N2 checkpoint 1680, a walking deployment model with four cameras, on Hugging Face. The repository includes ONNX graphs, TensorRT BF16 plans/engines, and the original checkpoint files, republished without retraining or re-export. The shared Cosmos-Reason1-7B dependency and the Isaac/GR00T runtime must be set up separately, and the files are not a robot safety qualification.

AIJetBrains released Mellum2.1, a 12B mixture-of-experts coding model with 2.5B active parameters under Apache 2.0, emphasizing agentic programming. Under high load, its inference throughput in tokens is nearly twice that of Qwen3.5-9B in JetBrains' comparison, and multi-token prediction (MTP) speeds single-request responses by about 1.6x. The model is available on Hugging Face for local or private-infrastructure deployment, with GGUF and vLLM MTP support announced for later.

AIA LoRA for MiniMax H3 removes a person from video by tracking them with SAM 3.1 and generating the replacement background in overlapping windows. Users supply the original video and a clean version of its first frame.

AIopenJiuwen, an open-source AI Agent platform built by Huawei teams with universities and enterprises, released and open-sourced an enterprise-grade AgentOS. It integrates multi-agent collaboration, self-evolution, compute affinity, multi-tenant isolation and security sandboxing, and a plugin architecture with the Agentic Hub ecosystem.

AIAdo Kukic posted a salute emoji reacting to Anthropic's launch of OSS Scanner, which uses frontier models to periodically scan opted-in open-source projects for vulnerabilities at no cost. The reports include a proof-of-concept, explanation, and suggested fix.

AIXiaomi MiMo has released MiMo-V2.5-ASR, an open-source speech recognition model that the company says achieves state-of-the-art results across multiple benchmarks. The model supports bilingual Chinese–English recognition, Chinese dialects such as Wu, Cantonese, Hokkien, and Sichuanese, code-switching, and lyrics transcription. It is also designed to handle noisy environments and multi-speaker conversations.

AIXiaomi introduces the MiMo-V2.6 series of models, as stated on its official MiMo page. The source excerpt gives only the tagline, describing frontier intelligence across all modalities, so specific capabilities, benchmarks, and availability cannot be confirmed from it.

AIDatabricks has released Funke, a Python and PySpark library and deployable pipeline that parses HL7v2 healthcare messages into native Spark types while preserving the full message hierarchy. It succeeds Smolder, the Scala data source Databricks open-sourced in 2021, and ingests through Auto Loader into Unity Catalog bronze and silver tables. Users can query segments, fields, components, and subcomponents directly with DataFrame or Spark SQL expressions.

AIAnthropic launches OSS Scanner, a free service that gives opt-in open-source projects periodic security scans by its strongest models, including Claude Mythos. The reports are fully model-generated without human review or triage, so Anthropic says some may be incorrect or invalid.

AIAnthropic is launching OSS Scanner, a service that uses its frontier models to periodically scan opted-in open-source projects for vulnerabilities at no cost. Its reports provide a proof-of-concept, an explanation, and a suggested fix.

AIThariq (@trq212) says the project is built on Claude Managed Agents, with code generated in a cloud sandbox using Sonnet 5.5. He puts each run at about $0.75 and links the GitHub repository for trying it.

AIClaude Code v2.1.295 adds onFailure: "block" for command and HTTP hooks, so a hook that cannot start, times out, or exits unexpectedly blocks the action. The release also adds an optional models list for Claude apps gateway upstreams, plus upstream_request_id in the inference audit event, and fixes a range of MCP, plugin, and terminal issues.

AISherwin Wu, an OpenAI employee, says the updated Harvey LAB-AA v1.1 benchmark, announced by Artificial Analysis with Harvey, is more useful than the original LAB results. The new Hallucination-Gated All-Pass Rate credits a task only when every rubric criterion passes and no material hallucination appears. Grok 4.7 (xhigh) leads at 9.4%, while GPT-6 Astra (max) at 8.6% has very few material hallucinations.

Why it matters: The update adds a hallucination gate to a legal benchmark, showing that models with high all-pass rates can rank much lower once material errors count.

AIOpenAI's Codex 0.162.0 release adds tools for creating and listing managed Git worktrees from trusted local projects when the worktrees feature is enabled. The update also lets users pin tasks in the agent Command Center, copy transcript blocks with /copy, and make URLs clickable in approval headers, questions, and warnings, along with several Linux and Windows sandbox fixes.

AILauren Tan invites users of Grok Bot on Omarchy and developers building plugins for it to share feedback and feature requests. The post points to the Omarchy plugin catalog and asks what integrations could be supported. Background from DHH says SpaceXAI joined the Omacom Foundation as a Founding Corporate Patron, contributing $1,500,000 in Grok tokens for Omarchy's maintenance and development.

AINVIDIA Dynamo uses a unified session-level identifier to make its inference stack aware of agent sessions, subagents, and their KV cache across turns and tool calls. On SWE-bench, two TP4 MiniMax-M2 replicas on one 8xH100 node gained roughly 12-16% throughput from program-aware scheduling over KV-aware routing alone. The post also describes experimental shared-pool indexing and a proposed KvHint interface for session-aware cache policies in vLLM and SGLang.

Why it matters: The post explains how session identifiers let an inference stack track agent working sets, with measured throughput gains on SWE-bench and agentic RL rollouts.
