TL;DR

  • The window also brought new open models, updates to developer platforms, and changes to GitHub’s Copilot applications. [1] [2] [3] [7] [8] [9] [10] [11] [12]

Models

Meta previewed Muse Video, a video-generation model with native audio, and released Muse Image for image generation and editing. [4] [5] Meta also released Muse Spark, a multimodal reasoning model supporting tool use and multi-agent orchestration. [6] New open models include JevK5 v0.3 for typed decisions, Fastino’s multilingual GLiNER2.5-multi-Decide, and Tsinghua SIGS Robot Lab’s VeriLoop E2 for code, mathematics and physics. [1] [2] [3]

Developer platforms

Cohere introduced Compass Cloud, a managed private-beta retrieval service available through APIs, an MCP server and a Python SDK. [7] Microsoft Foundry added capabilities for cost attribution, token limits, traces and evaluations; an ROI feature is in private preview. [8]

Applications

GitHub added configurable code-review settings, including an enterprise default review effort, to Copilot code review. [9] Copilot CLI added C++ whole-codebase indexing, while local sandboxing for the Copilot app entered public preview with per-project access policies. [10] [11] Copilot for JetBrains 1.18.0 added agent features, shared skills and instructions, and workflow controls. [12]

VeriLoop E2

VeriLoop E2 is an open 27B post-trained model built on Qwen3.8-27B for code, mathematics, and physics. It uses VeriLoop-Governed Recurrence, in which candidate states are externally checked and retained only when the protected evidence state improves without regression.

Muse Video

Muse Video is an early preview video-generation model built on the same pretraining base as Muse Image, delivering visual fidelity and native audio support with competitive prompt adherence and temporal consistency. It is being previewed for creators and integration into Meta AI with further work planned on audio-video synchronization and fast-motion physical accuracy.

Muse is being brought to Meta AI glasses, where it can act on what the wearer is looking at and be accessed by voice.

Muse Image

Muse Image is Meta Superintelligence Labs’ advanced image-generation model that follows instructions, edits with precision, composes from multiple references, and operates agentically by invoking tools and self-refining at inference. It is available in Meta AI app and on meta.ai and in select Meta endpoints (Instagram Stories in the US and limited WhatsApp availability).

Muse Spark

Muse Spark is a natively multimodal reasoning model from Meta Superintelligence Labs that supports tool use, visual chain-of-thought, and multi-agent orchestration. It is positioned as the first model in the Muse family and is available via meta.ai and the Meta AI app with a private API preview for selected users.

Microsoft Foundry

Microsoft Foundry is a developer platform for building, running, observing, and governing AI agents across an organization. The blog describes new and existing Foundry capabilities for cost attribution, token quotas/rate limits, traces/evaluations, and an ROI feature in private preview that links agent outcomes to costs.

Adds analysis of production traces to surface recurring and previously unrecognized issues, supporting evidence, likely causes, and recommended next steps.

Copilot code review

Copilot code review adds a dedicated per-user settings page and more granular automatic-review controls, plus an enterprise-level default review effort that can be inherited by organizations. These changes are generally available across Copilot plans including Business and Enterprise.

Adds a global default policy for generally available Copilot features and supported client capabilities in enterprise and organization settings.

Copilot CLI

Copilot CLI adds whole codebase indexing (WCI) for C++ that builds a persistent symbol index across a project so the Microsoft C++ Language Server can resolve symbols and relationships without repeatedly rediscovering them. The feature is enabled by default, can increase initial build time and memory usage, and the index is reused and dynamically updated thereafter.

Adds a global default policy for generally available Copilot features and supported client capabilities in enterprise and organization settings.

Copilot app (Local sandboxing)

Local sandboxing for the Copilot app provides per-project policies that limit filesystem, network, and credential access for local repository and working-tree sessions. The feature is available in public preview and is configurable in the app per project or for individual sessions with an in-session command.

Adds a global default policy for generally available Copilot features and supported client capabilities in enterprise and organization settings.
