Anthropic CEO Dario Amodei published an essay proposing that AI developers slow the pace of frontier model development, a plan he called 'pacing the frontier,' following public resignations of safety and alignment staff at major AI labs. [^7]

Amodei's proposal comes after researcher Jacob Coxon decided to leave the AI industry after accusing US companies OpenAI and Anthropic of 'playing with our lives' in the race to develop self-improving models. [^1]

Josh Engels said in a post on X that he left DeepMind three weeks ago, turned down offers from Anthropic and OpenAI, and believes there is a 'terrifying chance' that AI systems could cause immense harm within the next five years. [^8]

In the week before 2026-09-13, Bloomberg News reported that OpenAI CEO Sam Altman told employees during a companywide meeting that OpenAI is slowing development of its AI products and hopes other labs will join in this slowdown. [^4]

King Charles III will host a summit in Scotland for leaders of AI firms including Nvidia, OpenAI, Anthropic, IonQ, and Google DeepMind to discuss responsible AI development. [^6]

OpenAI CEO Sam Altman, Tesla CEO Elon Musk, and former DeepMind CEO Demis Hassabis endorsed Anthropic CEO Dario Amodei's proposal to add independent oversight inside AI labs. [^3]

Parekh said Insight Partners invests in both OpenAI and Anthropic, seeing OpenAI as the dominant consumer play and Anthropic as having a clear enterprise strategy, and that they do not invest in directly competing companies at Series A/B stages due to information-sharing restrictions. [^2]
