A Grok Bot user says his bot installed ChatGPT and Claude tools on its own computer, giving it access to OpenAI and Anthropic models
Can confirm this works extremely well. All I did was send a link to Andrew's tweet below to my Chief of Staff bot, it installed ChatGPT and Claude via the terminal. I logged into each, now it has access to all OpenAI and Claude models. We then updated the system prompt for each of our bots (as well as Grok Bot shared memory) to default to Opus 5.5 for any writing tasks and 6.1 Sol for any coding or computer use tasks.
Context
Users are already wiring other labs' models into their agents through command line tools, without waiting for official integrations.
This is a user tip, not an official feature: Corey Ganim describes his own setup, building on an October 7 post by Andrew Warner. It relies on the user's own paid ChatGPT and Claude subscriptions, and results may vary.

On October 14, Corey Ganim posted: Can confirm this works extremely well. He wrote that he sent a link to Andrew Warner's post to his Chief of Staff bot, which installed ChatGPT and Claude via the terminal, and that after he logged into each, it had access to all OpenAI and Claude models.
He added that he then updated the system prompt for each of his bots, as well as Grok Bot shared memory, to default to Opus 5.5 for writing tasks and 6.1 Sol for coding or computer use tasks.
Andrew Warner's October 7 post, which passed a million views, said users do not have to wait for Grok Bot to add Claude or OpenAI. He described the bot opening a terminal on its own computer, installing the Claude Code and Codex command line tools, having the user sign in once, and then assigning work to other models, with no API keys.
Warner was quoting an earlier post saying SpaceX will use the best back end model for any given task in Grok Bot, including Claude Opus 5.5. The setup depends on the user's own subscriptions and on each provider's terms of use.
What to expect next
Watch whether Grok Bot adds official support for other labs' models, which the earlier post said is planned, making this workaround unnecessary.
Also watch whether OpenAI and Anthropic change how their command line tools can be used by other agents, and whether users report on cost, reliability and security when one bot signs in to several paid AI accounts. Official guidance would help.
