Anthropic PBC today disclosed that it plans to develop a custom artificial intelligence chip, confirming earlier rumors. A spokesperson told Business Insider that the company will co-design the processor with its future large language models, a process that can significantly increase hardware efficiency by removing mismatches between off-the-shelf AI chips and the models they run. According to Business Insider, Anthropic is assembling an in-house chip development team, reportedly seeking processor designers and verification experts. A job posting indicates the company plans to automate some verification tasks using AI, developing simulations in which Claude can learn how to test newly designed chips, with emphasis on an evaluation method called formal valuation. OpenAI Group is also using AI to accelerate chip design; in June, it debuted a custom inference accelerator called Jalapeño, developed with Broadcom Inc., which took only nine months to design. It’s likely Anthropic’s chip will be optimized for inference workloads, as custom silicon can be much more cost-efficient than off-the-shelf graphics cards. Rumors of Anthropic’s effort first emerged in April, and in early June, The Information reported the company may partner with Samsung Electronics Co. to manufacture its processor. Samsung recently introduced a technology called zHBM that could significantly increase the efficiency of AI chips, and partnering with Samsung may enable Anthropic to incorporate zHBM into its upcoming accelerator.
