OpenAI is reportedly preparing the release of GPT-5.5, internally codenamed “Spud,” as the company’s first fully retrained large language model since GPT-4.5. The model is expected to be offered through ChatGPT in a Pro version and to compete with leading systems from Anthropic, Google, xAI, and Meta. Sam Altman reportedly told employees that the model could “really accelerate the economy” and would be released within a few weeks. GPT-5.5 could also become the foundation for the “Super App” that OpenAI has already publicly announced.
GPT-5.5 stands out because OpenAI has not trained a completely new base model since GPT-4.5. More recent work focused on refining, expanding, or optimizing existing systems for specific agentic uses. GPT-5.5 therefore represents a broader reset, with expectations that a model trained from scratch can deliver larger gains in performance and quality than later rounds of fine-tuning. The launch is being treated as a meaningful strategic and technical milestone rather than a routine iteration.
The model is described as natively omnimodal, allowing it to process text, images, audio, and video within a single system instead of combining separate modalities afterward. It is also expected to include a massively expanded context window, stronger reasoning, significant improvements in coding and UI generation from images, and better support for agent-based workflows in which the model carries out multi-step tasks more independently. These capabilities point to a system designed for more complex and practical use cases.
The timing reflects growing competitive pressure, especially in enterprise markets. OpenAI has reportedly been in an internal “Code Red” state since at least December 2025, after rivals including Anthropic and Google made substantial gains. In the B2B segment, Anthropic’s Claude is described as the leading option. OpenAI is responding by shifting away from compute-heavy creative tools such as the discontinued video generator Sora and toward more productive enterprise applications. A planned “Super App” combining ChatGPT, Codex, and a dedicated browser in a single desktop application is central to that strategy, with GPT-5.5 intended to supply the technical base.
