At a typical workload of 50,000 conversations a month with 1,500-token prompts and 800-token replies, GPT-5 costs roughly $494 per month. Input is $1.25 /1M tokens and output is $10.00 /1M tokens.
GPT-5 has a 400,000-token context window (large memory — an entire book or large codebase). That means you can fit about 75,000 words of input and history in a single call.
Beyond text generation, GPT-5 supports understanding images, deep step-by-step reasoning, calling functions / tools, strict JSON output, fine-tuning on your own data. It streams replies by default.
GPT-5 was released in August 2025, with training data cut off around September 2024.
Models in a similar class include GPT-5 Codex, GPT-5.1, GPT-5.1-Codex. The "Similar models" section below this FAQ links into each.
