OpenAI has released GPT-5, its new flagship model, positioning it as a significant leap in intelligence and capability. Described as having “PhD-level intelligence” across numerous fields, the model aims to simplify user interaction by automatically determining the necessary reasoning effort for a prompt, eliminating the need to choose between different model versions. The launch follows the strategic open-sourcing of a previous model, GPTO OSS, clearing the stage for this new state-of-the-art AI.
A New Level of Intelligence and Performance
GPT-5 demonstrates superior performance across a wide range of benchmarks, particularly in complex math, science, and coding tasks, where it even slightly edges out competitors like Anthropic’s Claude Opus 4.1. Despite these high scores, OpenAI acknowledges that benchmarks are becoming less indicative of a model’s real-world utility. Key enhancements in GPT-5 include its remarkable speed, its ability to understand subtle nuances in long, complex prompts, and its improved capacity to backtrack and self-correct when it goes down a wrong path. For safety, the model is designed with significantly lower hallucination and deception rates.
Key Features and Upgrades
The new model introduces several user-facing upgrades. It will be available to all users, with Pro subscribers gaining access to GPT-5 Pro for more intensive reasoning tasks. New features include:
- Integrations: Access to Gmail and Google Calendar to function as a personal assistant (rolling out soon).
- Voice Enhancements: The voice chat feature is now available to all users and is highly customizable, allowing for tailored responses and improved language translation.
- Custom Personalities: Users can choose from personalities like “Cynic” or “Nerd” to get less agreeable and more specialized responses.
- API Improvements: The API now offers a 400,000-token context window and new parameters to control `reasoning_effort` and `verbosity`.
Conclusion: A Powerful Tool for Coders, An Incremental Step for Others
While the demos showcased impressive one-shot capabilities—such as generating an interactive SVG animation, a complex financial dashboard, and a functional 3D game from a single prompt—the reviewer felt the launch was somewhat “underwhelming.” He noted that the leap from GPT-4 to GPT-5 didn’t feel as revolutionary as the jump from GPT-3.5 to GPT-4. He expressed a desire for more advanced multimodality (like integrated video generation with Sora), better project-specific memory, and a more accurate ability to mimic writing styles. The core takeaway is that OpenAI, like others in the industry, is heavily focused on coding as the “killer use case” for LLMs. GPT-5 is a game-changing tool for developers but may feel like a more incremental improvement for the average user for now.
Mentoring question
Given GPT-5’s advanced one-shot coding abilities, what small, custom application could you create this week to solve a recurring problem or automate a tedious task in your personal or professional life?
