OpenAI’s GPT-6 guide shifts attention from benchmarks to production design
OpenAI has published a practical guide for choosing and operating GPT-6 models, covering model tier, reasoning effort, caching, compaction, steering and long-running tasks. The 2 October guide urges teams to measure successful-task cost rather than token price alone. Its advice is useful, but production decisions still require representative evaluations and independent controls around tools and data.
