What changed in the major AI coding CLIs?

OpenAI released Codex v0.144.3 with remote control via ChatGPT app, DigitalOcean cloud workspaces, and multi-agent handoffs [4541]. The Codex Tag demo has been rewritten to be lighter (under 10k LOC) and faster, especially for long running tasks, and will be included in the upcoming v0.3.0 release [4543]. Undo is a new tool that gives files or coding agents an undo button, allowing preview of changes and selective reversal of unwanted work [4540]. Google's Gemma 4 model achieves up to 3x faster local inference using Multi-Token Prediction drafters, with the 31B model jumping from 20.8% to 89% on AIME [4539]. xAI open-sourced Grok Build, their Claude Code competitor, and five days earlier quietly released an official Claude Code plugin with 8 commands [4537]. Moonshot AI released Kimi Code CLI, an open-source (MIT) alternative to Claude Code with additional features like screen recording input and built-in subagents [4536]. Anthropic released an official plugin called claude-code-setup that analyzes projects and recommends automations like hooks, skills, MCP servers, and subagents [4534]. A GitHub repo allows Claude Code users to swap endpoints to use DeepSeek, Kimi, and 8 other free models, saving $200/mo [4533]. Anthropic released an official skill for Claude Code called Frontend Design, which forces Claude to pick an aesthetic direction before generating code, with 161k GitHub stars and 277k+ installs [4532]. Anthropic announces standardized Fable 5 access at 50% usage for plans that use it most intensively, acknowledging frustration and promising continued capacity investment [4529]. Anthropic launches Claude for Teachers, offering free premium Claude capabilities to verified K-12 educators in the US, with teaching skills and evidence-based curricula [4527].
