Amodei said he thinks delaying Claude's release had real commercial consequences for Anthropic.

The claim is that Anthropic held back the release of an early Claude model (in 2022, before ChatGPT) and that this had real commercial consequences, i.e. lost first-mover position, market share, revenue or attention to competitors. True: credible accounts (reporting, histories, statements from investors or former staff) confirm the delay happened and describe concrete commercial cost, such as OpenAI's ChatGPT capturing the market first. Mostly true: the delay is confirmed and commercial cost is plausibly shown, but evidence of the size of the cost is thin or mainly inferred. Mixed: the delay is confirmed, but evidence on whether it cost Anthropic commercially is balanced or contested. Mostly false: the delay is confirmed, but evidence suggests little or no commercial effect, or the delay was mainly for other reasons such as the model not being ready. False: evidence shows no such deliberate delay took place.

   “Months before ChatGPT existed, Anthropic had a working chatbot. Staff and friends used it inside Slack. People liked it.”

   ““Our general feeling was that it would cause too much acceleration,” co-founder Ben Mann said later.”

   “In November 2022, OpenAI launched ChatGPT, and it became the AI product the whole world knew.”

   “Claude finally launched in March 2023. That year, Anthropic made $41 million. OpenAI had a head start, a household name and Microsoft’s money.”

An independent newsletter reports that Anthropic had a working chatbot that staff used internally months before ChatGPT existed [E1]. It quotes co-founder Ben Mann as saying it was not released because it "would cause too much acceleration" [E2], which supports a deliberate delay. It also reports that ChatGPT launched in November 2022 and became the product the world knew, that Claude launched in March 2023, and that by then OpenAI had a head start and a household name [E3, E4]. That makes a commercial cost plausible, but the source does not measure any lost revenue or market share. All of this comes from one secondary source, so the evidence on how large the cost was is thin.
