🔥 This Month’s Highlights

Grok Build Beta — xAI’s AI Development Platform

Grok Build Beta is now available to SuperGrok and X Premium+ users. It supports Plan Mode for planning, creating images and videos via Imagine, and provides CLI tools for building automation workflows and orchestrators. For AI developers, this is a new platform worth watching.

🛠 Useful Tools

Qwen3.7-Max Implicit Cache

Tongyi Qianwen’s Qwen3.7-Max has launched an implicit cache feature — auto-enabled, no manual setup needed. The out-of-the-box accelerated cache makes inference faster and cheaper, suitable for high-frequency call scenarios. If you’re using the Tongyi Qianwen API, this feature can directly reduce usage costs.

📚 Learning Resources

Clarifying Harness, Scaffold, and AI Agent Terminology

Hugging Face published a practical article parsing AI agent terminology, clarifying key concepts in the Agent ecosystem:

  • Model — Memoryless, non-recurrent large language model
  • Scaffolding — Behavior definition layer (system prompts, tool descriptions)
  • Harness — Execution layer, responsible for model invocation, tool call processing, and control loop

The article points out that Agent = Model + Harness is the most practical understanding framework, using Claude Code and Codex as examples of how the same model paired with different Harnesses produces vastly different experiences.

🔬 Open Source Projects

OpenSenseNova — SenseNova-U1 Full Training Code Open-Sourced

The complete training codebase for SenseTime’s SenseNova-U1 has been open-sourced, supporting its 8B dense model and A3B MoE architecture. A unified framework enables simultaneous training of multiple multimodal tasks, including text-to-image generation, image editing, interleaved generation, and text & visual understanding.

For researchers and developers interested in deep-diving into multimodal model training, this is a highly valuable reference implementation.
