Abacus.AI CEO Bindu Reddy, citing "multiple reports," claims that progress in closed-source AI has come to a complete pause.

He specifically claims Anthropic's Model 2 (codename Fable 6) is being used internally but will not be released externally.

His takeaway: there has never been a better time for open source to catch up. Note: these are unverified rumors; treat model codenames and details with caution.
