OpenAI's upcoming model, GPT-5, is nearly here. The company plans on announcing the model in a "longer than usual" presentation today, which suggests the company has some interesting news up its sleeve. The thing is, the cat's out of the bag—at least partially—as some GPT-5 news has leaked ahead of the announcement. In a now-deleted blog post (archived here), we can see some of the new features and changes shipping with GPT-5. It'll come as no surprise that the post claims GPT-5 is OpenAI's "most advanced model," nor will it be a shock to learn that it improves "reasoning, code quality, and user experience" over previous models. However, the post does say the model can create and run code with "minimal prompting," and that it now has "enhanced agentic capabilities." Companies are now pushing agentic AI more than ever: Rather than simply generate results, like text, images, or videos, from prompts, agentic AI can run tasks on the users' behalf. ChatGPT's agent mode, for example, can take over your web browser to perform tasks for you, or create an excel doc based on a request for a specific spreadsheet. The post doesn't offer many other details in regard to GPT-5's performance and feature gains over previous models. We don't have any charts or figures to work from at this time. However, the post does share that GPT-5 is broken into four distinct models, depending on the use case. That includes:GPT-5: This model is for logic and multi-step tasks.GPT-5-mini: This model is not as powerful as GPT-5, and, as such, is designed for "cost-sensitive" applications. GPT-5-nano: This model is designed to be fast for "low latency" applications. GPT-5-chat: This is OpenAI's model for businesses to run multimodal and context-aware conversions.In addition to this leaked GitHub post, BleepingComputer reports it has seen documents suggesting OpenAI's pricing plan for GPT-5. Like previous models, users will be able to access GPT-5 for free. However, ChatGPT Plus subscribers may be able to access GPT-5 with "advanced reasoning," while ChatGPT Pro users may get "pro reasoning." Reasoning models take extra time to "think" through a query, breaking down the request into individual steps before processing the request. BleepingComputer says GPT-5 can sync between reasoning and non-reasoning automatically, but that you can prompt it to reason at any time.That's about the extent of our GPT-5 knowledge as of this article. However, we won't have to wait long to learn more: The leak comes just hours before OpenAI is set to officially announce its latest model, so it won't be long before we see how GPT-5 compares to other models, like GPT-4o, Google's Gemini, and Anthropic's Claude.
