GPT-5 Overview & Core Features
💡 Described as a unified system for efficient model and real-time routing based on query complexity.
🧠 Introduces adaptive "thinking mode" (e.g., "think hard about this"), allowing the model to allocate more compute time for complex problems.
🚀 Focuses on reducing hallucinations and improving instruction following, particularly for common use cases like writing, coding, and health.
🎨 Shows significant improvements in front-end coding generation, demonstrated with interactive games and dashboards.

Performance Benchmarks & Efficiency
📈 GPT-5 (High mode) is state-of-the-art on the Artificial Analysis Intelligence Index (aggregate of 8 evaluations), outperforming all other models.
🥇 Achieves best-in-class performance in MMLU Pro, Humanity's Last Exam, AMIE, long context, and instruction following benchmarks.
💲 Offers a superior intelligence-to-output tokens used ratio, indicating high efficiency in terms of speed and cost, often at half the cost of competitors like Grok 4 for similar tasks.
📊 While not outperforming on every single benchmark (e.g., GPQA Diamond, site coding), it exhibits strong general capabilities across the board.

API Access & Pricing
🔗 Available via API with four models: GPT-5, GPT-5 Mini, GPT-5 Nano, and GPT-5 Chat, all supporting multimodal input (text and image).
💸 Flagship GPT-5 model priced at $1.25 per million input tokens and $10 per million output tokens, offering better performance than Gemini 2.5 Pro at the same price point.
📏 Features a significantly larger 400,000-token context window and a max output of 128,000 tokens across all model sizes.
🛠️ Includes features like streaming, function calling, structured outputs, and predicted outputs (in the flagship model) useful for code refactoring and text editing.

Key Use Cases & Accessibility
🏥 Demonstrates improved, less robotic responses for sensitive health queries, providing more empathetic and relevant information.
💻 Praised by the CEO of Cursor as the "best coding model" used to date, showing strong performance on the Junior Dev Eval benchmark.
🌐 GPT-5 is rolling out to all users, with Plus subscribers receiving more usage and Pro subscribers gaining access to GPT-5 Pro for extended reasoning.
🧪 Platforms like Windsurf and Cursor are providing free access to GPT-5 for coding contexts, allowing users to try it out.

Key Points & Insights
➡️ Leverage GPT-5's advanced capabilities for tasks requiring high intelligence, such as complex coding, detailed writing, and nuanced health-related queries, to enhance productivity.
➡️ When considering AI tools, evaluate models based on intelligence-to-token efficiency and overall performance rather than just raw speed, as GPT-5 offers significant cost and output quality advantages.
➡️ Explore the expanded context window and multimodal input features of GPT-5 to handle larger, more complex datasets and diverse input types for more comprehensive AI applications.
➡️ Utilize early access opportunities on platforms like Windsurf and Cursor to integrate GPT-5's cutting-edge features into coding and development workflows, staying ahead in AI adoption.
