What changed in the major AI coding CLIs?
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 [2231], alongside fixes for background sessions restoring blank [2238], auto-naming not showing in agent view [2237], malformed bracket patterns breaking file operations [2236], compound cd commands unnecessarily prompting for permission [2235], auto-updater overwriting custom launcher scripts [2234], spurious prompt-injection warnings [2233], remote managed settings bypassing consent dialogs [2232], very large markdown tables stalling rendering [2230], truncated stream-json/JSON output from `claude -p` [2229], lost replies to background agents [2228], fast mode not restoring after model switch [2227], and timeline outlines getting clipped [2243] and clipped labels and branch tooltips [2242]. Removed accidentally shipped interface transition changes [2241]. Added OAuth support for Luna Responses Lite [2240] and removed an obsolete Codex workaround interfering with OpenAI Luna Responses Lite requests [2239]. Added mouse-click support for multi-select menus in fullscreen mode [2226], `vimInsertModeRemaps` setting [2225], and screen reader mode [2224]. 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].[25]
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 and new features [2224–2243].[5]
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]
Updated Claude Code fixes and features to the latest batch (ids 2224–2243), replacing the previous batch (2191–2210). Added screen reader mode, vim insert-mode remaps, and mouse-click support for menus. Removed outdated references to earlier fix IDs.
