OpenAI, the company behind ChatGPT and led by Sam Altman, has taken a new step in the evolution of artificial intelligence with the launch of GPT-5, its most advanced model to date. This announcement marks a significant transformation in the way people and businesses access reasoning, comprehension, and task execution capabilities with the help of AI.

During the GPT-5 presentation, Sam Altman made it clear that OpenAI aims to simplify its products and offer a “magical and unified intelligence”, eliminating the model picker that many users found confusing. With GPT-5, the AI decides in real time whether it should respond quickly or take a moment to “think” more deeply before acting.
This approach translates into a more seamless experience, where users no longer need to choose between speed, reasoning, or vision—GPT-5 handles it all on its own.
What is GPT-5 and why is it so relevant for OpenAI?
GPT-5 is OpenAI’s new flagship model, and it represents a consolidation of all the improvements from previous generations. According to OpenAI, it’s not just an evolution of GPT-4—it’s a completely new platform that unifies multiple development paths: from structured reasoning to integration with external tools and the ability to understand instructions more precisely.
The company states that GPT-5 has been designed to be more accurate, faster, safer, and more useful in real-world scenarios, both for individuals and organizations. It’s an AI capable of generating software, analyzing complex clinical contexts, writing technical reports, organizing calendars, or interacting intelligently with other digital systems.
How do you access GPT-5 in ChatGPT?
GPT-5 is already available directly through ChatGPT, across several access tiers:
- ChatGPT Free: includes GPT-5 as the default model, though with limited access. Once the free usage limit is reached, a reduced version called gpt-5-mini is activated.
- ChatGPT Plus: for $20 per month, users get more interactions with GPT-5, with stable performance and extended capacity.
- ChatGPT Pro: for $200 per month, users gain access to GPT-5 Pro, an enhanced version with deep reasoning, voice, canvas, integrated search, and higher computational power.
- Enterprise, Team, and Edu plans: will receive GPT-5 as the default model starting next week, with access to reinforced versions according to corporate or academic needs.
What new features does GPT-5 include?
In addition to improvements in accuracy and performance, GPT-5 introduces key upgrades:
- Ability to solve complex problems
- Better capacity to maintain context over long conversations
- Improved understanding of subtle and nuanced instructions
- Compatibility with external tools and ability to execute actions
- New response personalities in ChatGPT: Cynic, Robot, Listener, and Nerd—each adjusting tone and style automatically.
What versions of GPT-5 are available via OpenAI’s API?
OpenAI has released three versions of GPT-5 in its API for developers, each designed for different use cases:
- gpt-5: for complex tasks involving logic, reasoning, and natural language processing.
- gpt-5-mini: a lightweight, more affordable version ideal for fast responses or budget-sensitive systems.
- gpt-5-nano: optimized for extreme speed and low latency, perfect for mobile apps or real-time interactions.
The official pricing for GPT-5 API usage is:
- $1.25 per million input tokens
- $10 per million output tokens
How powerful is GPT-5 compared to other models?
In benchmarks like SWE-bench Verified, focused on GitHub tasks, GPT-5 achieved a 74.9% first-attempt success rate, outperforming Claude Opus 4.1 (74.5%) and Gemini 2.5 Pro (59.6%).
Additionally, GPT-5 Pro showed an error rate of just 4.8%, significantly lower than GPT-4o (20.6%) and o3 (22%), establishing itself as the most reliable model so far.
What other announcements came with the launch of GPT-5?
The release of GPT-5 is part of a broader strategic rollout by OpenAI:
- Launch of GPT-OSS, its open-weight model designed to run offline.
- Unification of the “o-series” and GPT models under a single system.
- Integration of technologies like o3 directly into GPT‑5 (which will no longer ship as separate systems).
