GPT-V

OpenAI's fifth-generation multimodal LLM: GPT-5 unifies fast processing and deep reasoning, achieving 94.6% accuracy on advanced mathematics.

GPT-5 (Generative Pre-trained Transformer 5) is OpenAI's flagship multimodal foundation model, launched August 7, 2025. This unified architecture automatically routes queries between 'Fast Mode' for routine tasks and 'Deep Reasoning' for complex challenges, eliminating guesswork for developers. Performance metrics confirm significant gains: the model achieves 74.9% accuracy on real-world coding tasks (SWEBench) and sets a new state-of-the-art score on the GDPval knowledge work benchmark, performing at or above human expert level in 70.9% of comparisons. Access the system via the OpenAI API or through ChatGPT Plus (using the gpt-5-thinking-pro variant).
