GPT-5 arrives: OpenAI’s best yet?

🚨 Our Report 

After weeks of speculation and rumors, OpenAI has finally launched GPT-5, which CEO Sam Altman is calling its “best model” yet, that represents a “significant step” towards developing AI that can outperform humans (aka Artificial General Intelligence). While GPT-4 gave quicker and smarter responses to questions, GPT-5 is more agentic and can complete a range of tasks (like building apps, accessing calendars, and creating briefs) on behalf of users. In a nutshell, GPT-5 will make ChatGPT quicker, more helpful, and easier to use.

🔓 Key Points

  • “Personal coder,” GPT-5, “builds apps in minutes,” excels at “vibe coding” (coding using natural language) and scored 74.9% on a renowned coding benchmark, outperforming Anthropic’s Claude Opus 4.1 (by 0.4%).

  • It’s also OpenAI’s “best model yet for health-related questions,” scoring higher than any previous model on benchmarks that are “based on realistic scenarios and physician-defined criteria.”

  • Its hallucination rate is 26% lower than GPT-4o and it responds with incorrect information just 4.7% of the time. While this sounds promising, it does mean that 1 in 10 responses will still contain hallucinations.

    (Slightly concerning, given it’s OpenAI’s “best model” for healthcare?)

🔐 Relevance 

This launch has been highly anticipated, and expectations are high, but OpenAI has given all ChatGPT users access to GPT-5 because it wants to make sure “this stuff actually benefits people,” referencing its long-standing mission to distribute advanced AI to as many people as possible.

Mentors.net - a Professional Development Resource

Mentors.net was founded in 1995 as a professional development resource for school administrators leading new teacher induction programs. It soon evolved into a destination where both new and student teachers could reflect on their teaching experiences. Now, nearly thirty years later, Mentors.net has taken on a new direction—serving as a platform for beginning teachers, preservice educators, and

other professionals to share their insights and experiences from the early years of teaching, with a focus on integrating artificial intelligence. We invite you to contribute by sharing your experiences in the form of a journal article, story, reflection, or timely tips, especially on how you incorporate AI into your teaching

practice. Submissions may range from a 500-word personal reflection to a 2,000-word article with formal citations.
