Summary & Key Takeaways ​

• OpenAI announced a massive 80% price drop for GPT-5.6 Luna and 20% for GPT-5.6 Terra.
• The price reduction was enabled by GPT-5.6 Sol optimizing the model's forward pass and kernel code.
• GPT-5.6 Sol autonomously rewrote and optimized production kernels using Triton and Gluon.
• GPT-5.6 Luna is now significantly cheaper than competitors like Gemini 3.1 Flash-Lite and Claude Haiku 4.5.
• This move drastically changes the landscape for lower-priced, high-performance models.

Our Commentary ​

Eighty percent! That's not just a price drop; it's a seismic shift. We've been talking about the cost of frontier models, and this move by OpenAI, driven by their own AI optimizing its inference, is a game-changer. It makes advanced AI dramatically more accessible and will undoubtedly accelerate innovation across the board. I genuinely didn't expect such an aggressive move so soon. The competitive landscape just got a lot more interesting.
