OpenAI rolls out new model built for speed, codingBloombergOpenAI is releasing its first artificial intelligence (AI) model that runs on chips from semiconductor startup Cerebras Systems Inc, part of a push by the ChatGPT maker to broaden the pool of chipmakers it works with beyond Nvidia Corp. The model, GPT-5.3-Codex-Spark, is intended to be a less powerful but quicker version of its most recent Codex software for automating coding. The Spark model, slated to be released on Thursday, lets software engineers quickly complete tasks such as editing specific chunks of code and running tests. Last month, OpenAI signed a deal worth more than US$10 billion for hardware from Cerebras to get quicker responses from its AI models. Codex has more than 1 million weekly active users, OpenAI said.
