The AI world is buzzing. On March 24, 2026, reports surfaced that OpenAI CEO Sam Altman told employees they had completed pre-training on the company's next major AI model—internally codenamed "Spud." Altman described it as a "very strong" model that could "really accelerate the economy." With a potential release just weeks away, here's everything we know about the most anticipated AI model of 2026.
What's Inside
What Is Project Spud?
"Spud" is the internal codename for OpenAI's next flagship AI model. First reported by The Information on March 24, 2026, the model has completed its pre-training phase—a critical milestone that signals it's moving toward fine-tuning and eventual public release.
While OpenAI hasn't officially confirmed the codename or released technical specifications, insider reports paint an ambitious picture. Sam Altman reportedly told employees that Spud represents a significant leap in capability over existing GPT models, with particular emphasis on economic productivity—a clear signal of the model's enterprise-oriented ambitions.
The model emerges at a pivotal moment for OpenAI. The company has been in an internal "Code Red" state since late 2025, as competitors like Anthropic's Claude and Google's Gemini have narrowed the gap significantly. Spud is OpenAI's answer—a concentrated bet on building the most powerful language model yet. See our deep dive into how Spud stacks up against Claude, Gemini, and the competition.
Development Timeline
Here's what we know about Spud's development journey:
- Late 2025: OpenAI enters "Code Red" as competitors close the gap, accelerating work on next-gen models
- Early 2026: OpenAI makes the controversial decision to shut down Sora (its AI video generation tool) to redirect GPU resources to Spud's training
- March 24, 2026: Sam Altman announces to employees that Spud's pre-training is complete
- March 25, 2026: Sora app, API, and planned ChatGPT integration are officially discontinued
- Coming weeks: Post-training, safety evaluations, and anticipated public release
The decision to sacrifice Sora—a product that generated massive public attention—underscores just how critical Spud is to OpenAI's strategy. Video generation requires enormous GPU compute, and every chip running Sora was a chip not training Spud. Read our full analysis of why OpenAI killed Sora to power Spud.
Expected Capabilities
While OpenAI hasn't disclosed specific benchmarks or technical details, we can piece together likely capabilities from context clues:
Enterprise-Grade Intelligence
Altman's emphasis on "accelerating the economy" strongly suggests Spud will be optimized for business and enterprise use cases. Expect significant improvements in:
- Complex data analysis and synthesis
- Long-context reasoning and document processing
- Agentic task execution with greater autonomy
- Multi-step planning and workflow automation
Advanced Coding Capabilities
OpenAI's strategic pivot toward coding tools—including the Codex product—suggests Spud will deliver a major step up in code generation, debugging, and software engineering tasks. This aligns with the company's focus on competing directly with Anthropic's Claude, which has earned a strong reputation among developers.
Multimodal Improvements
Given the broader industry trend and OpenAI's previous multimodal work with GPT-4o, Spud will almost certainly improve upon vision, audio, and document understanding capabilities.
The Super App Vision
Spud doesn't exist in isolation—it's the engine powering OpenAI's ambitious "super app" strategy. According to reports, OpenAI plans to combine multiple products into a single desktop application:
- ChatGPT — Conversational AI interface
- Codex — AI coding assistant and IDE-like tool
- Proprietary browser — Deep web integration with AI-powered search
This super app approach represents OpenAI's vision for AI as not just a chatbot, but a comprehensive digital workspace. Spud will serve as the intelligence layer connecting all these products into a seamless experience.
When Will Spud Launch?
Based on Altman's comments, Spud could be released "within a few weeks" of the March 24 announcement—placing a potential launch window in mid-to-late April 2026.
However, several factors could affect the timeline:
- Post-training: After pre-training, the model needs extensive fine-tuning, reinforcement learning from human feedback (RLHF), and safety alignment work
- Safety evaluations: OpenAI's Preparedness Framework requires thorough safety testing before deployment
- Staged rollout: Like previous models, Spud will likely launch first to ChatGPT Plus/Pro subscribers before wider availability
A staged launch in April 2026, starting with API access and premium ChatGPT tiers, seems most likely.
GPT-5.5 or GPT-6?
One of the biggest questions is what Spud will be called publicly. The two leading candidates:
GPT-5.5: An incremental naming that positions it as an evolution of the GPT-5 family. This seems more likely given OpenAI's recent naming pattern (GPT-5.4 mini was released in March 2026).
GPT-6: A full generational leap in branding, signaling a paradigm shift. This would be bolder but riskier if the model doesn't deliver a clear generational improvement in user experience.
Industry speculation leans toward GPT-5.5 or a similar iterative name, but the final branding depends on how OpenAI's internal evaluations stack up. If the performance gap is truly significant—which Altman's excitement suggests—don't rule out a full GPT-6 launch.
What It Means for AI Users
For everyday AI users, Spud's arrival could mean:
- Noticeably smarter responses: Better reasoning, fewer hallucinations, and more nuanced understanding
- Better tool use: Improved ability to browse the web, execute code, and complete multi-step tasks autonomously
- Enhanced productivity: Faster, more accurate assistance for work tasks from writing to data analysis
- New pricing tiers: OpenAI may introduce new subscription tiers to monetize Spud's capabilities
For developers and businesses, the implications are even bigger—Spud could reshape how AI is integrated into production workflows and enterprise software.
The Bottom Line
OpenAI's Spud model represents the company's most consequential bet since GPT-4. By shutting down Sora, reorganizing the company around an "AGI Deployment" division, and putting everything behind this model, OpenAI is signaling that Spud is meant to leap ahead of the competition. Whether it lives up to the hype will become clear in the coming weeks—but the stakes have never been higher.
