    GPT-6 Luna being half the price of GPT-5.6 Luna is a really big deal.

    Here&#x27;s GPT-6 Luna pelicans: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=https%3A%2F%2Fgist.github.com%2Fsimonw%2F40d129fc140faca378b9c9f4f16c6ec2" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=ht...

    And GPT-6 Sol: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=https%3A%2F%2Fgist.github.com%2Fsimonw%2Fbe7ae25af2634b68bc34b7b7aaf02cb2" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=ht...

    Scroll to the bottom for the GPT-6 Sol max one: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=https%3A%2F%2Fgist.github.com%2Fsimonw%2Fbe7ae25af2634b68bc34b7b7aaf02cb2#response-5" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=ht...

    For comparison, here are the pelicans I got for GPT-6 Astra: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=https%3A%2F%2Fgist.github.com%2Fsimonw%2Ff789d2784fc6c5b870cc80f0b7cd9d01" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=ht... - I still like the Astra Max one best.

    Here&#x27;s a comparison grid showing all of the GPT-6 and GPT-5.6 pelicans at all effort levels: <a href="https:&#x2F;&#x2F;static.simonwillison.net&#x2F;static&#x2F;2026&#x2F;gpt-6-and-5.6.html" rel="nofollow">https:&#x2F;&#x2F;static.simonwillison.net&#x2F;static&#x2F;2026&#x2F;gpt-6-and-5.6.h...

    The grid is actually really interesting, because it shows that the 5.6 family default to brighter colors than the 6 family.

      Is GPT-6 50% cheaper?

      &gt; GPT‑6 Luna vs. GPT‑5.6 Luna | $0.20 → $0.10 | $1.20 → $0.50 | 50% cheaper

      I can read it as follows (below), meaning that GPT-5.6 is 50% cheaper.

      - GPT-6 = $0.20

      - GPT-5.6 = $0.10

        The table on <a href="https:&#x2F;&#x2F;developers.openai.com&#x2F;api&#x2F;docs&#x2F;pricing" rel="nofollow">https:&#x2F;&#x2F;developers.openai.com&#x2F;api&#x2F;docs&#x2F;pricing is more readable:

          Yeah, how they put, is confusing to me, they should have put that table instead of what they have right now in the article.
