**OpenAI Introduces GPT-5: An Extensive Overview of Upgrades and Features**
In a recent lengthy video presentation, OpenAI revealed the rollout of GPT-5, bringing forth a variety of improvements to its chatbot interface and overall functionality. This article delivers a thorough exploration of the major updates and characteristics of ChatGPT.
### One Model to Lead Them All
OpenAI has streamlined its model selections, combining them into three primary categories:
– **GPT-5**
– **GPT-5 Thinking**
– **GPT-5 Pro** (accessible exclusively through the US$200/month subscription)
The enhanced system enables ChatGPT to adeptly assess the duration needed to process user inquiries. Users may choose GPT-5 Thinking for a prolonged reasoning approach. Importantly, free users will now have access to the same model as Plus subscribers, albeit with limited usage thresholds, after which they will be transitioned to a ‘mini’ variant of the model. The details of these thresholds are not specified.
Moreover, OpenAI has retired all earlier models. Interactions with previous models will seamlessly switch to their corresponding GPT-5 version, ensuring a consistent user experience.
### Performance Improvements
OpenAI highlighted enhancements in GPT-5’s performance across an array of benchmarks, such as software development and multilingual code editing. While the performance improvements are not as striking as in prior updates, there is a noteworthy decrease in the rate of hallucinations, particularly concerning health topics.
### Customization Features
ChatGPT now includes four unique personalities along with a customizable Default mode:
– **Cynic**: Sarcastic and straightforward, offering practical responses with humor.
– **Robot**: Efficient and detached, supplying succinct replies.
– **Listener**: Warm and contemplative, providing calm clarity and gentle humor.
– **Nerd**: Playful and inquisitive, explaining ideas with zeal.
Users can also personalize the interface with accent colors, enriching their interaction experience.
### Google Integration
Commencing next week, Pro users will be allowed to link their Google Calendar, Contacts, and Gmail with ChatGPT, facilitating more tailored assistance. This feature is designed to streamline schedule management and task coordination directly through the chatbot.
### Safety and Health Protocols
OpenAI stressed its new “safe completion” feature, which clarifies why certain requests may not be met rather than simply declining them. This method aims to enhance user awareness of the model’s limitations. The company also noted the decreased hallucination rate in health discussions, illustrating how GPT-5 can responsibly assist users in comprehending medical conditions and treatments.
### Developer Tools
OpenAI invested considerable time demonstrating development tools and practical applications, showcasing the model’s capabilities in educational games and interactive presentations. Developers will have the option to adjust verbosity levels for GPT-5, facilitating better management of API and token usage. Access to GPT-5, along with mini and nano iterations, will be available through the API with a context window of 256,000 tokens.
The pricing model for the API is outlined as follows:
– **GPT-5**: $1.25/million input tokens, $10/million output tokens
– **GPT-5 mini**: $0.25/million input tokens, $2/million output tokens
