GPT-5

OpenAI's GPT-5: The unified, multimodal foundation model delivering PhD-level reasoning and state-of-the-art coding performance.

Copy that: GPT-5 is OpenAI's flagship multimodal model, launched August 7, 2025, as the successor to GPT-4. This is a major architectural shift: it unifies advanced reasoning capabilities (like the 'o-series' models) and rapid response times into a single system, eliminating the need for manual model switching (Source: OpenAI, August 2025). The model demonstrates state-of-the-art performance across technical benchmarks (math, programming, finance) and features a massive 272,000-token context window (Source: Jagran Josh, Voiceflow). Developers access it via the API in variants—including `gpt-5-mini` and `gpt-5-nano`—optimized for latency and cost trade-offs, making this frontier intelligence accessible across all ChatGPT tiers (Source: Botpress, Jagran Josh, Voiceflow).
