The Mark Cuban Podcast: Episode Summary
Title: Why OpenAI’s New AI Agents Are Causing a Stir
Release Date: August 9, 2025
Introduction to OpenAI’s New Open Models
In this episode, The Mark Cuban Podcast delves into the recent significant move by OpenAI: the release of two open source AI models. Mark Cuban discusses the broader implications of this decision, highlighting that it marks the first time in five years OpenAI has released open source models, reverting back to GPT-2 levels. This release has sparked considerable debate and criticism, particularly from figures like Elon Musk, who has been vocal about his concerns with OpenAI's approach to AI development.
Key Points:
- Open Source Release: OpenAI has unveiled two open source models, a notable shift after five years of withholding such releases.
- Criticism and Backlash: The move has attracted criticism, especially from Elon Musk, who had previously criticized OpenAI for not being open enough in its AI developments.
Benchmarks and Performance Analysis
Mark Cuban provides an in-depth analysis of how these new open models perform, comparing them against existing OpenAI models and other open source alternatives.
Code Force Benchmark
The first benchmark discussed is the Code Force benchmark, which measures the models' capabilities in coding-related tasks.
- 120 Billion Parameter Model:
- Score: Achieved an Elo score of approximately 2600.
- Comparison: Close to OpenAI’s O3 model (2700) and O4 mini model (2720).
- Performance Insight: While not surpassing OpenAI's proprietary models, the open models perform commendably, outperforming the O3 Midi model which scored around 2000.
Notable Quote:
"These are, these things aren't very far apart. It definitely did better than the O3 Midi model, which only got 2,000."

Humanities Last Exam Benchmark
The second benchmark is the Humanities Last Exam, a rigorous test designed to evaluate the model's understanding and reasoning in complex, interdisciplinary subjects.
- Performance:
- 120 Billion Parameter Model: Scored 19%
- 20 Billion Parameter Model: Scored 17%
- Comparison: While these scores are modest, they outperform several leading open models from Chinese companies like Deep SEEK and Quentin. However, they fall short compared to OpenAI’s closed source models.
Notable Quote:
"I was actually really impressed that the 20 billion parameter model got 17%. That's not very far behind 19%, which is the 120 billion parameter model."

Understanding Tools and Their Impact
Cuban emphasizes the importance of evaluating AI models both with and without tools. "Tools" refer to supplementary software like calculators or specialized applications that aid the AI in performing tasks more accurately.
Key Points:
- With Tools: Models have access to external applications to enhance performance.
- Without Tools: Models rely solely on their internal capabilities, which can lead to limitations.
- Implications: OpenAI's open models are released without these proprietary tools, potentially affecting their standalone performance.
Notable Quote:
"Tools basically mean they gave the AI model things like calculators and apps and like different tools. So like it is completing the tasks. Yes, but it's able to rely on like actual hard software to get good results."

Hallucinations and Model Reliability
A significant concern highlighted is the tendency of AI models to "hallucinate"— generate inaccurate or fabricated information.
Key Points:
- Hallucination Rates: OpenAI’s 120 billion parameter model exhibits a 49% hallucination rate on the Person’s QA benchmark, significantly higher than its proprietary O3 and O4 models.
- Impact: High hallucination rates undermine the reliability of AI models, especially in tasks requiring factual accuracy.
- Explanation from OpenAI: The increased hallucinations are attributed to smaller models having less world knowledge due to fewer parameters and training data.
Notable Quote:
"Basically they're blaming on the fact that there's less data, less parameters inside of these models. That's why they're hallucinating more."

Licensing and Open Source Implications
OpenAI has released these models under the Apache 2.0 license, which is notably permissive and allows for commercial use without requiring payments or permissions from OpenAI. This contrasts with other companies like Meta, which impose restrictions on monetizing their open models.
Key Points:
- Apache 2.0 License: Enables companies to modify, distribute, and commercialize the models freely.
- Monetization Freedom: Users can charge for services built on these models without infringing on OpenAI’s proprietary rights.
- Partial Openness: While the models are open source, OpenAI has withheld the training data, likely due to legal constraints related to copyrighted material.
Notable Quote:
"OpenAI is being really generous letting people make money off of it. They don't have to pay OpenAI and they don't have to get permission from OpenAI."

Safety Concerns and Delayed Releases
The release of these models was delayed multiple times due to safety concerns. OpenAI prioritized ensuring that the models would not be misused for cyber attacks or the creation of biological or chemical weapons.
Key Points:
- Safety Enhancements: Implementation of guardrails to prevent the models from generating harmful information.
- Third-Party Evaluations: External assessments indicated minimal increases in the models' capabilities for dangerous tasks, ensuring safer deployment.
- Final Release Decision: After extensive testing and fine-tuning, OpenAI deemed the models safe for public release.
Notable Quote:
"They had a bunch of third party evaluators actually test it and they said that it marginally increases biological capabilities, but it didn't find evidence that they were going to have a very high capacity threshold for danger in these domains after fine tuning."

Microsoft’s Integration of OpenAI Models
Expanding on the topic of AI integration, Cuban discusses Microsoft’s initiative to incorporate OpenAI’s smaller 20 billion parameter model into Windows through the Windows AI Foundry platform.
Key Points:
- Accessibility: Available to Windows 11 users, requiring systems with at least 16GB of VRAM.
- Capabilities: Optimized for agentic tasks such as code execution and tool utilization, making it suitable for building autonomous assistants and embedding AI into workflows.
- Platform Support: Runs efficiently on a range of Windows hardware, with plans to support more devices in the future.
- Developer Potential: Encourages innovation by allowing developers to build applications that leverage these powerful AI models directly within the Windows environment.
Notable Quote:
"It's perfect for building autonomous assistance or embedding AI into real world workflows, even in bandwidth constrained environments."
