Frontier AI intelligence, now at half the price
OpenAI expands the GPT-6 family with Sol and Luna with faster, cheaper models trained like Astra. 50% lower API pricing, near-Astra factuality/coding/computer use gains, better prompt caching (90% off cached reads), and alignment improvements. Live in ChatGPT Work, Codex, and via API.
OpenAI's GPT-6 Sol and Luna offer faster and more cost-effective AI models with a 50% reduction in API pricing. These models feature enhanced factuality, coding capabilities, and improved prompt caching, available through ChatGPT Work, Codex, and API.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
Overall, comments reflect mixed feelings with concerns about quality and performance, but some excitement about cost efficiency.
GPT-6 Sol and Luna extend OpenAI's newest model family below Astra, trained the same way but tuned for speed and cost. What makes it different: Sol beats Claude Opus 5 on Automation Bench at roughly 9% of the cost per task, and matches Claude Fable 5.1 on DeepSWE at about 80% lower cost. Both models also carry over Astra's alignment gains, including fewer misleading claims about their own coding work. Key features: 50% lower API pricing than GPT-5.6 equivalents Prompt caching improvements, 90% discount on cached input reads Near-Astra factuality, coding, and computer-use performance Who it's for: developers and teams running high-volume or long-running agent workflows who need frontier-level performance without frontier-level cost.

Day by day it's getting complete bullshit, useless, previously I was saying everybody that chatgpt is good but it's too bad more and more less than a child memory. useless specially now a days just after astra is launched. chat gpt just moved normal chat gpt veriosn to astra and made normal chatgpt version is bullshit ever no body can expect this. it's not able to change the font weight from a single html and css file. and so on i have seen. you guys are not fixing just launching new version. update should be fixed not to create a completely new version which has so many bugs. The chatgpt says always yes even if something is totally incorrect. is this you guys have Artificial intelligence mind??
Does the prompt caching for Sol and Luna work the same way as it does for Astra?
Now why don't you reply keep increasing version and instead of fixing in new version it's getting more and more bullshit. you guys are just trying to pull money from pockets not launching the right things.
