Within the combat between two “agentic” coding equipment — Anthropic’s Claude Code and OpenAI’s Codex CLI — the latter seems to be fostering extra developer goodwill than the previous. That’s a minimum of partially as a result of Anthropic has issued takedown notices to a developer seeking to reverse-engineer Claude Code, which is underneath a extra restrictive utilization license than Codex CLI.
Claude Code and Codex CLI are dueling equipment that accomplish a lot of the similar factor: permit builders to faucet into the ability of AI fashions working within the cloud to finish quite a lot of coding duties. Anthropic and OpenAI launched them inside months of one another — each and every corporate racing to seize precious developer mindshare.
The supply code for Codex CLI is to be had underneath an Apache 2.0 license that permits for distribution and industrial use. That’s by contrast to Claude Code, which is tied to Anthropic’s industrial license. That limits how it may be changed with out specific permission from the corporate.
Anthropic additionally “obfuscated” the supply code for Claude Code. In different phrases, Claude Code’s supply code isn’t readily to be had. When a developer de-obfuscated it and launched the supply code on GitHub, Anthropic filed a DMCA grievance — a copyright notification soliciting for the code’s removing.
Builders on social media weren’t happy through the transfer, which they stated in comparison unfavorably with OpenAI’s rollout of Codex CLI. Within the week or so since Codex CLI’s free up, OpenAI has merged dozens of developer tips into the instrument’s codebase, together with one who we could Codex CLI faucet AI fashions from rival suppliers — together with Anthropic.
Anthropic didn’t reply to a request for remark. To be honest to the lab, Claude Code continues to be in beta (and a bit of buggy); it’s imaginable Anthropic will free up the supply code underneath a permissive license at some point. Firms have many causes for obfuscating code, safety concerns being certainly one of them.
It’s a quite unexpected PR win for OpenAI, which in contemporary months has shied clear of open-source releases in want of proprietary, locked-down merchandise. It can be emblematic of a broader shift within the lab’s method; OpenAI CEO Sam Altman previous this yr stated he believed that the corporate has been at the “incorrect facet of historical past” relating to open supply.
