Highlights
The headline change is GPT-5.6 cache write billing: OpenAI cache_write_tokens are now charged at the cache-creation rate, with accounting safeguards around cached and uncached prompt tokens. This release also improves pricing workflows, Playground controls, channel table usability, and billing/logging reliability.
