Stronger Coding Capabilities: End-to-end code generation, better front-end UI outputs with minimal prompting, and effective debugging.
Improved Reliability and Safety: With over 5,000 hours of safety testing, GPT-5 reduces hallucinations and increases factual accuracy, especially in critical multi-step tasks.
Expanded Multimodal Support: Combining text and vision inputs with a very large context window, GPT-5 can handle long documents and mixed media for richer, more versatile interactions.
Much Larger Context Length: GPT-5 supports a context length of up to 400,000 tokens and can generate outputs as long as 128,000 tokens, enabling processing of extensive content in one interaction.
Better Customization and Steerability: Businesses can choose different AI “personalities,” control verbosity, and tune behavior to suit specific use cases and brand voices.
Voice and Interaction Upgrades: Improved voice understanding and configurable speaking styles support more natural conversational workflows and enhance human-AI collaboration.
Enterprise Integrations and Context Awareness: Seamless connection with company files and apps like Google Drive and SharePoint, with strict respect for data permissions and privacy.
New API Features for Developers: Includes minimal reasoning and verbosity parameters, stronger agent tool calling, and orchestration capabilities for sophisticated, programmatic workflows.
Key Differences Between GPT-5 and GPT-4o
Compared to GPT-4o, GPT-5 delivers longer context handling, deeper reasoning, and stronger multimodal performance. While GPT-4o excels in speed, certain non-English or audio tasks, GPT-5 is built for more complex, high-precision use cases.
Context: GPT-5 up to 400,000 token context window; GPT-4o supports low latency.
Output: GPT-5 up to 128,000 tokens; GPT-4o favors relatively shorter replies.
Modalities: GPT-5 text, vision & better voice features; GPT-4o text, audio, image, video.
Expertise: GPT-5 deeper reasoning; GPT-4o strong in non-English, vision, and audio.
Enterprise: GPT-5 with connectors and API controls; GPT-4o broad ChatGPT access.
The table below highlights the key differences between ChatGPT-5 and ChatGPT-4o for a clearer comparison.
