Pre-training is done. Sam Altman said "a few weeks." One unverified source leaked April 14. Prediction markets give under 10% probability of a launch before May. And somewhere inside OpenAI's Stargate data centre in Abilene, Texas, the most anticipated AI model in years is sitting in safety evaluation.

GPT-6 is the most searched AI topic on the internet right now. Most of what is being written is speculation dressed as analysis, or clickbait with no real sources behind it.

This page is different. We track only confirmed statements, credible signals, and clearly labelled rumours. We update it the moment the official announcement drops.

What We Know for Certain About GPT-6

Before anything else: here are the only facts worth treating as real.

Pre-Training Completed on March 24, 2026

OpenAI finished pre-training the model codenamed "Spud" on March 24, 2026, at the Stargate data centre in Abilene, Texas. This has been confirmed by multiple credible AI research trackers and is consistent with statements from OpenAI leadership. The training cluster ran on over 100,000 H100 GPUs as part of OpenAI's $500 billion Stargate infrastructure project.

That is not a side project. That is everything.

Sam Altman Said "A Few Weeks"

On March 24, the same day pre-training concluded, Altman publicly described the launch timeline as "a few weeks." That is the closest thing to an official release window the public currently has.

"A few weeks" from March 24 puts the earliest plausible release somewhere in mid-to-late April. But safety evaluation, red-teaming, and deployment preparation all happen after pre-training ends. Altman is known for optimistic framing.

Greg Brockman Called It "Two Years of Research"

OpenAI President Greg Brockman described Spud as representing two years of research and used the phrase "big model feel." That is the most direct internal signal available. This is not an incremental update.

The Model Name Is Still Unconfirmed

Spud may ship as GPT-5.5, GPT-6, or something else. OpenAI has not committed to either publicly. The final name depends on how significant the jump over GPT-5.4 is assessed to be internally. Most external analysts expect the GPT-6 label. We will confirm this the moment it is announced.


The Three Most Credible Release Window Scenarios

There is no confirmed date. Here is how the three scenarios stack up based on available evidence.

Scenario 1: April 2026 (Low Probability, Not Zero)

One unverified insider leaked an April 14 launch date alongside a "super app" combining ChatGPT, Codex, and the Atlas browser. The reported specifics include a 40% performance improvement over GPT-5.4 and a 2 million token context window.

The problem: the source is unverified and the numbers are suspiciously precise. Safety evaluation for a model at this scale rarely compresses to under three weeks from pre-training completion. Prediction markets currently assign under 10% probability to a May launch, let alone April. Monitor April 14. Do not make business decisions around it.

Scenario 2: May to June 2026 (Most Likely Window)

Taking Altman's "few weeks" literally and assuming a standard 4 to 6 week safety evaluation cycle puts May or early June as the most defensible estimate. The broader AI research community describes Q2 2026 as the consensus window.

OpenAI also has clear competitive pressure. With Claude Mythos and Gemini 3.1 Pro both expected in Q2, moving fast matters. But fast in AI safety terms still means thorough.

Scenario 3: Q3 2026 (If Safety Review Extends)

Some infrastructure analysts have pointed out that the full hardware stack for GPT-6 inference at scale will not be mature until the second half of 2026. If OpenAI wants to reliably serve 900 million ChatGPT users from day one, a Q3 window makes operational sense even if the model is technically ready earlier.

This scenario gains more weight when you factor in OpenAI's IPO preparation. Shipping a capacity-limited launch before going public would be a serious problem.


Why OpenAI Shut Down Sora: What It Signals for GPT-6 Timing

The Sora shutdown on March 24, 2026, was not just a product decision. It was a resource signal.

Sora was burning an estimated $1 million per day in compute costs at peak. Its total lifetime in-app revenue came to $2.1 million. Monthly downloads fell roughly 66% between November 2025 and February 2026. The app was shrinking while the costs stayed high. The economics were never going to work, and OpenAI's own team admitted it.

What makes the timing significant: OpenAI shut Sora down on the exact same day pre-training on Spud concluded. According to TechCrunch's reporting, compute freed from Sora went directly toward GPT-6. The $1 billion Disney licensing deal built around Sora died with it. OpenAI absorbed that loss anyway.

That tells you one thing clearly. OpenAI is not hedging on GPT-6. They are betting the whole company on it.

For businesses, there is also a practical lesson here. Disney found out about the Sora shutdown less than an hour before the public did. A billion-dollar partner, given under 60 minutes notice. If your business operations are deeply tied to a single AI vendor's product decisions, you are exposed in ways you may not have mapped yet. This is exactly the kind of vendor risk we think about when designing AI automation workflows for our clients.


GPT-6 vs Claude Mythos vs Gemini 3.1 Pro: The Current Landscape

GPT-6 is not out yet. Any comparison right now is forward-looking.

As of April 2026, the frontier is genuinely fragmented. GPT-5.4 leads on knowledge work tasks and computer use. Gemini 3.1 Pro leads on scientific reasoning and abstract thinking. Claude Sonnet 4.6 leads on coding benchmarks. No single model dominates across the board.

Spud's apparent mission, based on available signals, is to close the gaps where GPT-5.4 trails and extend its lead in knowledge work. OpenAI has made GDPval, its proprietary knowledge work benchmark, its primary commercial differentiator. If Spud also delivers the "novel capability" internal sources have hinted at without being specific, the current benchmark picture may shift dramatically.

Anthropic's Claude Mythos is also expected in Q2 2026. Some AI researchers are calling April and May 2026 the most consequential months in AI model history. Both releases are coming. The question is which lands first and how significant the gap actually is.

The full comparison will be updated here once benchmark results are published. Follow our blog for analysis when it drops.


Should You Wait for GPT-6 Before Building Your AI Stack?

No. And this is probably the most useful thing on this page.

The businesses pausing their AI work to wait for GPT-6 are making the same mistake people made in 2023, waiting for GPT-5 before doing anything with GPT-4. Their competitors were shipping. They were waiting. That gap compounds.

The models available right now are genuinely capable. We have seen AI automation compress a 30-day client workflow to 5 to 10 days. Not with GPT-6. With tools available today. The model matters less than the implementation.

When GPT-6 launches, switching to it should require changing a model parameter in your API call, not rebuilding your entire stack. If your current AI setup would require a full rebuild to upgrade, that is a design problem, not a model problem.

The best preparation for GPT-6 is building clean, well-structured AI workflows now on current models. Messy data and vague prompts will not get better with a smarter model. The fundamentals do not change between generations.

Frequently Asked Questions

What is the confirmed release date for GPT-6?

Arrow Icon

There is no confirmed public release date for GPT-6 as of April 2026. Pre-training on the model codenamed Spud was completed on March 24, 2026. Sam Altman described the launch as "a few weeks" away on the same date. The most credible consensus among AI researchers places the release window in Q2 2026, with May or June being the most likely months.

What is OpenAI's "Spud" model?

Arrow Icon

Spud is the internal codename OpenAI has been using for its next major model, believed to be GPT-6 or GPT-5.5. Pre-training was completed on March 24, 2026, at the Stargate data centre in Abilene, Texas. OpenAI President Greg Brockman described it as two years of research with a big model feel. The final public name has not been confirmed.

Why did OpenAI shut down Sora?

Arrow Icon

OpenAI shut down Sora on March 24 and 25, 2026, primarily because the cost of running the product was not sustainable. The service was estimated to cost around $1 million per day in compute at its peak, while total lifetime in-app revenue came to $2.1 million. Monthly active users had also dropped sharply from around one million to under 500,000. The freed compute was redirected toward GPT-6 development and inference preparation.

How does GPT-6 compare to Claude Mythos and Gemini 3.1 Pro?

Arrow Icon

GPT-6 has not launched yet, so a direct comparison is not possible. As of April 2026, the frontier is fragmented: GPT-5.4 leads on knowledge work benchmarks, Gemini 3.1 Pro leads on scientific reasoning, and Claude Sonnet 4.6 leads on coding. GPT-6 is expected to close the gaps where GPT-5.4 currently trails. Benchmark comparisons will be updated here once the model is publicly released.

Should I wait for GPT-6 before building my AI stack?

Arrow Icon

No. The models available right now are already capable of delivering real business results through automation. Waiting for GPT-6 delays the value you could be generating today and does not meaningfully change what is possible. A well-designed AI system built now should allow you to upgrade to GPT-6 with a simple model parameter change, not a full rebuild.
