   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.

      6-luna is at the pareto for most of the tasks! I dont know how they make money here but its insane value from a closed source model. I&#x27;d go further and say it makes no sense (privacy, sovereignty etc aside) to use many other models as its not only expensive but also many providers don&#x27;t have that much GPUs to serve at a significant volume. <a href="https:&#x2F;&#x2F;openrouter.ai&#x2F;rankings?view=month#top-models" rel="nofollow">https:&#x2F;&#x2F;openrouter.ai&#x2F;rankings?view=month#top-models 5.6 luna is already the most used model this month.

         Can&#x27;t agree more. Between 5.6 Luna and Gemini 3.8 flash I&#x27;m so happy for the value I&#x27;m getting for my dollar (subscription pricing not API pricing) :)

         1. jadbox · 1790103881 · focus · HN ↗

            Gemini 3.8 Flash looks like its better than v7 Luna&#x2F;Sol on DeepSWE v1.1 while at $0.75 per million input tokens and $3.75 per million output tokens. Luna is much cheaper, but Flash has nearly Astra&#x27;s performance for under the price of Sol ($2&#x2F;$10).

               Flash thinks much more so it’s pretty much line with Sol for performance. That said I like flash coding style much more than OpenAi models.

                  out of curiosity, what type of code&#x2F;language do you usually use flash to write?

                        what harness or plan are you using 3.8 flash with?

                        1. Kostchei · 1790139031 · focus · HN ↗

                           anti-gravity with gemini 3.8 or gtfo
