OpenAI Releases GPT-5

OpenAI released GPT-5 on August 7, 2025 as a unified ChatGPT system combining fast responses with deeper reasoning. Instead of requiring users to choose manually between a general model and a reasoning model for every request, the system used routing logic to decide when more computation was useful.

OpenAI emphasized improvements in coding, mathematics, visual understanding, factuality, and tool use. GPT-5 also arrived as agentic applications were becoming more common, so model behavior had to remain coherent across longer workflows involving external tools.

The unified design was technically significant because model selection became part of the product itself. An AI system could optimize latency and cost dynamically, giving easy prompts a fast path while allocating more inference-time computation to difficult problems.
