Uncle Matt (@Unc_MattEth) reports that he modified garrytan's gbrain project to authenticate and run via his existing ChatGPT Pro/Codex WebLogin rather than purchasing another API key. He released the fork and usage instructions at github.com/uncmatteth/gbrain (post dated 2026-06-09) and credits @garrytan for the original repo.
On 2026-06-09, @Unc_MattEth adapted garrytan's GitHub repo (github.com/garrytan/gbrain) to run through OpenAI Codex/WebLogin so he didn't need to buy an additional API key
i wanted to use github.com/garrytan/gbrain by @garrytan
i already pay for chatgpt pro/codex so i wanted to use that weblogin
I Made GBrain Think Through Codex Without Buying Another Damn API Key
