🧠 Master GPT-4.1, o3 & o4-mini [Workshop]

Hey there.

At one point or another, different AI platforms have been able to make a pretty strong claim to be the best… but there’s no doubt which tool is the most popular.

With over 400 million active monthly users, ChatGPT is the name most people think of when they think about AI. 

This week, OpenAI gave the platform its biggest upgrade in over a year by releasing GPT-4.1, o3, and o4-mini. Which means, for now at least, ChatGPT can safely claim to be the most popular and the best. 

And for AI enthusiasts, that makes it impossible to ignore.

Inside The Rundown AI University, we’re helping our members keep up with these new capabilities as the gap between professionals who know how to use them effectively and those who don't begins to widen rapidly.

Once you know how to make the most of these new models, here's what they’ll help you do:

1. Solve problems no AI could tackle before

Most AI users have a list of tasks they know AI can’t do. But new updates bring new capabilities, and new automation opportunities.

If you have manual work that AI hasn’t been able to take off your hands yet, OpenAI's flagship reasoning model might feel like science fiction.

o3 can:

• "Think visually," analyzing charts, diagrams, and data visualizations alongside text

• Work autonomously with tools — browsing the web, running code, and generating images without hand-holding

• Make 20% fewer major errors than earlier models (finally making AI reliable enough for critical work)

2. Scale ‘impossible’ workloads at a fraction of the cost

Eventually, capabilities don’t matter as much when the results are too expensive to achieve. There’s always been a balancing act that comes with affordable automation.

However, the impressive o4-mini is solving the AI cost-performance problem.

The newly released model helps you:

• Get nearly identical reasoning capabilities to premium models

• Process hundreds of requests simultaneously without delays

• Handle text and images across high-volume applications

• Pay 60% less than comparable models while getting better results

3. Turn massive documents into actionable insights

While it isn’t always easy to tell which model is the latest, (is 4o better than 4.5, and are they related to o4-mini?) rest assured, GPT-4.1 is a definite improvement in what's possible.

With the models 1,000,000 token context window (roughly 750,000 words), you can now:

• Analyze entire codebases that would overwhelm other models

• Extract insights from collections of research papers without losing context

• Transform technical documentation into working implementations

• Connect dots across massive datasets that would be impossible to process manually

This API-only model is transforming how forward-thinking teams work. Companies with access are completing projects with 21% better code quality and dramatically reduced debugging cycles.

However, you can't simply log into ChatGPT and access these capabilities. You need specific API implementation knowledge that most professionals don't have yet.

Fortunately, this week’s workshop is designed to cover that in detail…

Join Dr. Alvaro Cintas tomorrow at 4 PM EDT to discover:

• What’s new in GPT-4.1, from improved coding and long-context support to better instruction following and efficiency

• Prompting techniques that actually work — how to structure prompts, use chain-of-thought, and optimize outputs

• How to use GPT-4.1 through the API for your personal or professional projects

By the end of the workshop, you’ll be ready to unlock the full potential of GPT-4.1 and start building with the latest powerful model from OpenAI.

The challenge isn't whether these models will transform the world of work — it's whether you'll know how to implement them while they provide a rare competitive edge.

Whether you're building applications, automating workflows, or simply trying to stay ahead of the AI curve, this workshop will give you implementation knowledge your competitors simply don't have.

P.S. There’s a good chance you’ve already heard about this week’s releases but while most professionals are still figuring out the basics (or expecting the new models to work like the old ones!), our workshop will give you the advanced implementation techniques that deliver real results.
