For the novel projects I'm working on, Astra did unblock me where I was stuck with GPT 5.6 Sol, which in itself gives it value for myself, but outside of that it's not a significant improvement if at all. I have noticed Astra is more efficient so for my use case it may not be 2.5x cost. |", "url": "https://wpnews.pro/news/ask-hn-is-gpt-6-astra-worth-the-2-5x-cost-increase-over-gpt-5-6-sol", "canonical_source": "https://news.ycombinator.com/item?id=49661691", "published_at": "2026-09-11 17:03:10+00:00", "updated_at": "2026-09-11 17:18:46.326265+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "generative-ai"], "entities": ["GPT-6 Astra", "GPT-5.6 Sol", "Hacker News", "minimaxir", "Fable", "Opus"], "alternates": {"html": "https://wpnews.pro/news/ask-hn-is-gpt-6-astra-worth-the-2-5x-cost-increase-over-gpt-5-6-sol", "markdown": "https://wpnews.pro/news/ask-hn-is-gpt-6-astra-worth-the-2-5x-cost-increase-over-gpt-5-6-sol.md", "text": "https://wpnews.pro/news/ask-hn-is-gpt-6-astra-worth-the-2-5x-cost-increase-over-gpt-5-6-sol.txt", "jsonld": "https://wpnews.pro/news/ask-hn-is-gpt-6-astra-worth-the-2-5x-cost-increase-over-gpt-5-6-sol.jsonld"}}
