   Cerebras hits post-IPO low as market worries OpenAI may shift orders to NVIDIA

   Cerebras Systems shares fell 10.69% on Oct. 12 to $146.62, a record low since its May IPO and more than 20% below the $185 offer price and over 60% below its post-listing high. According to Barron's, investors fear that its largest customer OpenAI is moving some AI inference workloads to NVIDIA: the research firm SemiAnalysis said OpenAI's new GPT-6.1 Sol Ultrafast runs on NVIDIA GPUs rather than Cerebras silicon. About $20 billion of Cerebras's roughly $24.6 billion revenue backlog comes from OpenAI, and roughly 19.4 million shares are due to be unlocked from lock-up on Oct. 14, potentially adding selling pressure. OpenAI CEO Sam Altman publicly backed Cerebras earlier this month, briefly lifting the stock before it slid again.

   OpenAI rolls out GPT-6.1 Sol Ultrafast, up to 8x faster than Sol Standard

   OpenAI said its Ultrafast version of GPT-6.1 Sol is rolling out in the API, Codex and ChatGPT Work, offering what it describes as "near-Astra intelligence at up to 8x faster speeds than Sol Standard." On the API it is pay-as-you-go at $12 per million input tokens and $60 per million output tokens, six times the standard Sol rate of $2/$10, and OpenRouter said the model is live on its platform the same day. In Codex and ChatGPT Work, Ultrafast is limited to Pro 500 subscribers, qualifying pay-as-you-go Enterprise users and Edu users, and some developers reported that its token consumption is correspondingly fast.
