AI developer Tibor Blaho found references to a "limited preview" of GPT-4.5 in ChatGPT's code, suggesting OpenAI plans to make it available to Teams subscribers. Blaho has accurately spotted upcoming ChatGPT features in code before, though some took months to actually launch. We've seen GPT-4.5 rumors for at least a year now. Last March, an OpenAI blog post about "GPT-4.5 Turbo" briefly showed up in search results before disappearing. While The Verge recently claimed OpenAI would release a new AI model in December, CEO Sam Altman called that report a "random fantasy." But now Altman is teasing a big announcement for next Monday.
Meta has released Llama 3.3, a new AI model that matches the capabilities of its larger Llama 3.1 405B while using significantly less computing power. The company says the model excels at tasks such as generating synthetic data while keeping inference costs low. The improvements come from a new alignment process and advances in online reinforcement learning techniques, according to Meta. The model is now available through Hugging Face and will roll out to partner platforms soon. Meta notes that Llama 3.3's efficient design allows it to run on standard developer workstations without requiring specialized hardware.
