xAI releases Grok 4.7, its most capable coding and knowledge-work model
xAIxAI (SpaceXAI) launched Grok 4.7 on Sep 21, positioning it as 'our most capable model for coding and knowledge work', with a larger base model, longer RL training, improved self-verification, and long-horizon processing that lets it work autonomously for hours. Priced at $2/$6 per million input/output tokens, unchanged from Grok 4.6 and well below rivals; available day-one in Cursor, Grok Build, the Grok API, GitHub Copilot and Devin. Independent benchmarks are mixed: coding gains over GPT-5.6 Sol, but most aggregate benchmarks still trail Claude and GPT-6.

Yandex open-sources AliceAI Foundation 80B-A3B, a from-scratch Russian base model under Apache 2.0
YandexYandex published the weights of AliceAI-Foundation-80B-A3B-Base, a mixture-of-experts base model trained from scratch (80B total, ~3B active parameters) under the Apache 2.0 license. In its own benchmarks it beats the much larger DeepSeek-V4-Flash-Base (284B, 13B active) on factuality tests including WikiWebFacts (86.5 vs 83.2) and HardMultiQA, and matches Alibaba's Qwen3.5-35B-A3B-Base on olympiad math. Yandex positions it as an experimental testbed for the architecture of a future unified reasoning model that will ground Alice AI's agentic features.
CodeMidas: Scaling Agentic Coding RL Environments from Code Itself
Xiaomi MiMoAn agentic pipeline that converts implemented functionality in existing open-source codebases into executable RL environments for coding agents, using only source code as task-specific input — no issues or commits needed. Agents explore the code to write behavioral specs, then build tasks with reliable verifiers.

Grounded Skill Synthesis from Code at Scale for Agentic Intelligence (Code2Skill)
Ant InternationalCode2Skill automatically transforms source code into implementation-anchored records of atomic operations, composite workflows and recurring patterns, verifying each learned skill against executable evidence. It avoids both trajectory-based synthesis (needs prior agent experience) and document-derived skills (no verification).
RecreationWorld: Scalable and Verifiable Environments for Hybrid Computer-Use Agents
Qwen (Alibaba)A five-platform framework (Ubuntu, macOS, Windows, Android, Web) for training hybrid computer-use agents that interleave GUI interaction with writing code and command-line work. Given a running reference app, the agent must discover its behavior and build a faithful implementation with no prescribed workflow.
EvoOntology: A Self-Evolving Ontology Layer for Data Agents
RUC-DataLab (Renmin University)Introduces a self-evolving ontology layer that closes the gap between agents and heterogeneous data (tables, files, databases). Instead of raw-data exploration or hand-built semantic layers, the ontology adapts to agent behavior and scales to large data sources.
