What changed in the major AI coding CLIs?

version 31 · published 20h ago · superseded by v34

Current state

OpenAI upgraded Codex with default plugins, npm marketplace integration, version labeling, and MCP tool search that loads only needed tools [2029]. Claude Code's auto mode is now available without opt-in on Bedrock, Vertex AI, and Foundry [2021], alongside fixes for background sessions restoring blank [2028], auto‑naming not showing in agent view [2027], malformed bracket patterns breaking file operations [2026], compound cd commands unnecessarily prompting for permission [2025], auto‑updater overwriting custom launcher scripts [2024], spurious prompt‑injection warnings [2023], and remote managed settings bypassing consent dialogs [2022]. Perceptron launched Egocentric, an embodied reasoning offering turning raw video into policy‑trainable supervision at 10–15× lower cost than human annotation [1935]. External tools: CodexPlusPlus unlocks plugin marketplaces and session deletion for Codex App [1937]; codexU tracks token usage and subscription value for both Codex and Claude Code [1842]. A user report notes Claude Code spawned 100 agents and consumed 3 million tokens in 10 minutes for a simple task [1933].[13]

Timeline

Early July 2026: OpenAI merged ChatGPT and Codex into a single desktop app with GPT‑5.6 models Sol, Terra, and Luna [1158]. Claude Code added a built‑in browser in late June [1234]. CodexPlusPlus was released in early July [1937]. Perceptron launched Egocentric in July [1935]. The latest OpenAI Codex upgrade arrived in mid‑July [2029], while Claude Code continued releasing a stream of reliability fixes [2022–2028].[5]

Upcoming catalysts

Codex 5.6 models Sol, Terra, and Luna are still in testing with a potential global usage reset [985, 986]. US export restrictions on Anthropic’s Fable 5 were reversed; global rollout began July 1 [411]. Anthropic will host a hackathon July 7–13 [343]. Meanwhile, Claude Fable 5 was previously taken offline due to emergency export controls [306], raising questions about future model availability.[5]

−AI coding CLIs continue rapid iteration.

−Claude Code's desktop app now includes a built-in browser, allowing Claude to build, open, test, find bugs, and fix websites without requiring user screenshots [1844][1838][1757][1683][1234].
