    Microsoft AI has released an 80 billion parameter MoE large model MAI-Base-2.

    Microsoft AI has completed the pre-training of a new MoE large model MAI-Base-2, with 80 billion active parameters and 2.8 trillion total parameters, surpassing all open-source models in internal evaluations. The model is 4-12 times more efficient in pre-training FLOPs than the strongest open-source base model DeepSeek-V4-Pro-Base and is used to train larger models. Microsoft plans to license the model weights through Foundry using organic data pre-training and full-stack control.

    How does Google Antigravity accelerate the discovery of antibacterial peptides?

    The Google Antigravity platform works through its intelligent agent workbench and ProtNLM model, helping biologists quickly discover, structure evaluate, and prioritize potential antimicrobial peptide targets, compressing searches previously scattered across multiple databases into a single session. The platform uses ProtNLM to predict protein function and supports researchers in scanning millions of uncharacterized proteins in the UniProt database. Researchers collaborate with AI agents on a shared 3D canvas, compressing the time required for the antimicrobial peptide discovery process from several days to a single session.

    YouTube Music will use AI tags to distinguish human-created music from AI music

    YouTube Music has started using AI tags to identify human-created music and AI music. The tag is similar to the AI tag for YouTube videos and will be displayed on the playback page. Clicking on it can view more information. Google states that it cooperates with partners and uses self-developed tools to detect AI music, but publishers can voluntarily label the extent to which AI is used (full/partial/no).

    How to evaluate AI agents: Beyond sensory checks.

    Evaluating AI agents cannot rely solely on perception checks, as agents may fall into retry loops or produce hallucinatory responses that still appear normal, leading to soaring cloud costs and token usage. A repeatable evaluation process should be established, starting with defining key user journeys (CUJ), using simulated user testing, and employing multiple layers of checks such as unit tests, deterministic metrics, LLMs as judges for scoring standards, and integration tests. Combining manual review tracking with automated validation can detect latent regressions early in development and expand the evaluation framework as agent capabilities grow.

    Google OAuth Launches DPoP Support: Protecting Refresh Token Security

    Google OAuth Platform Launches DPoP Support, Encrypting Refresh Tokens and Client Key Pairs at the Application Layer to Prevent Token Theft and Replay Attacks. This scheme uses DPoP only for constrained long-lived refresh tokens, ensuring they cannot be replayed even if stolen, while short-lived access tokens remain standard Bearer tokens to maintain high performance. DPoP works with DBSC to defend against API and web session credential theft, but note the key sharing challenges in multi-agent workflows.

    How LangChain Deep Agents Manage Context Windows Through Middleware

    LangChain Deep Agents manage context windows through middleware, preventing unnecessary information from entering and filtering existing content. It employs techniques such as offloading (saving large tool results and user messages to files), summarization (compressing old messages), skills (loading on demand), sub-agents (separating noisy tasks), and long-term memory (preserving learning across sessions). These techniques are implemented by inserting middleware at critical points like model calls and tool calls, allowing users to use them without writing code.

    How to evaluate the control and monitoring of internal AI agents

    Assessors can collect evidence of the reliability of internal AI agent monitoring by monitoring five core sub-questions: coverage, system vulnerability monitoring, evasion monitoring, response mechanisms, and potential impact. The focus of the assessment is on LLM monitoring, as agents typically have broad permissions, requiring an understanding of their full range of actions. The assessment requires access to reasoning logs, monitoring logs, and employee interviews, and checks whether there are blocking monitors and whether unmonitored reasoning is indeed non-agent reasoning.

    IBM will launch the 7-nanometer nanoscale stacking technology early research and development process design kit (PDK) in the first quarter of 2027.

    IBM announced that it will launch an early research and development process design kit (PDK) for 7-nanometer nanoscale stacking technology in the first quarter of 2027, to help semiconductor companies evaluate the technology before large-scale adoption. The kit will provide a standard cell library for logic functions and SRAM design examples, supporting layout and routing, early module-level layout, and density and power performance evaluation. Nanoscale stacking technology achieves 3D layout at the transistor level for the first time on logic wafer technology by stacking transistors vertically rather than placing them side by side, which is significantly different from current nanosheet transistor architectures.
