Latest Development: Reduced Hallucinations in OpenAI's Updated GPT-5 Model, Now with up to 80% Improvement
OpenAI Unveils GPT-5: A More Reliable and Versatile AI
In a groundbreaking development, OpenAI has introduced its latest model, GPT-5. This new AI model promises key improvements over previous versions, including unified, adaptive reasoning, dramatically reduced hallucinations, and improved accuracy, particularly in complex and technical domains [1][2][3][5].
Unified Adaptive Reasoning
Unlike past models, GPT-5 no longer requires users to pick distinct specialized models. Instead, the system uses a real-time routing architecture that seamlessly balances speed and depth, providing quick or in-depth responses as appropriate [1][3].
Reduced Hallucinations
GPT-5 cuts hallucination rates by about 80% compared to GPT-o3 and about 45% compared to GPT-4o, especially on complex, open-ended factual queries. Benchmark tests (LongFact, FActScore) show about six times fewer hallucinations than older reasoning-focused GPT-o3, representing a substantial step forward in factual reliability [1][5].
Expanded Training Data
GPT-5 is trained on much larger and more varied datasets, including proprietary sources that cover niche topics, underrepresented languages, and complex real-world scenarios. This broad and deep training improves handling of specialized technical questions, longer conversations, and non-English languages [4].
Multimodal Capabilities
Building on GPT-4's limited text-plus-image ability, GPT-5 advances multimodality by supporting speech, vision, and reasoning seamlessly in a single model without switching interfaces. Users can interact via text, images, or spoken input naturally [4].
Customizability
GPT-5 offers enhanced customization options for individuals and enterprises, allowing adjustments to tone, workflow preferences, or domain-specific behaviors, enabling better alignment with particular use cases such as business, education, or content creation [4].
New User Experience Features
GPT-5 introduces selectable chatbot personalities (e.g., cynic, robot, listener, nerd) to tailor interaction style and context. The model is also easier to use since it eliminates the need to choose different models manually [3][2].
Expert-Level Performance
OpenAI CEO Sam Altman likens GPT-5’s performance to interacting with a "legitimate PhD-level expert," reflecting significant gains in the model's reasoning sophistication and domain knowledge [2][3].
Pricing and Availability
Pricing for ChatGPT remains unchanged at $20 a month for the Plus tier and $200 a month for the unlimited Pro tier. ChatGPT Free and Plus users will have access to GPT-5 and GPT-5 mini, while Pro and Enterprise users will have access to a Pro variant that can reason for longer. API users will also have access to a Nano version at a reduced cost, alongside the standard and mini models [6].
OpenAI's GPT-5 is now available for Free, Plus, and Pro users, with enterprise and educational users to follow next week [1]. This new model positions itself as a more robust, reliable, and versatile AI compared to its predecessors [1][2][3][4][5].

- In the realm of science and technology, OpenAI's GPT-5, a more advanced AI model, offers unified adaptive reasoning, making it unnecessary for users to select distinct specialized models, thereby providing quick or in-depth responses as the situation demands [1][3].
- One of the significant improvements in GPT-5 is the dramatically reduced hallucinations, which are about 80% fewer than GPT-o3 and about 45% fewer than GPT-4o, especially on complex, open-ended factual queries [1][5].
- Enhanced customization options in GPT-5 cater not only to individual needs but also to the specific requirements of enterprises, enabling adjustments to tone, workflow preferences, or domain-specific behaviors for better alignment with business, education, or content creation purposes [4].
