Summary & Key Takeaways ​

Anthropic released Claude Opus 5.5. OpenAI launched GPT-6 Sol and GPT-6 Luna. GPT-6 Sol and Luna are priced at half their GPT-5.6 equivalents. GPT-6 Luna is now one of OpenAI's cheapest models ever at $0.10/$0.50 per million tokens. The new pricing significantly undercuts competitors like Grok 4.7. GPT-5.6 models face a scheduled 25% price increase, making GPT-6 even more competitive. Visual comparisons of model outputs show distinct stylistic differences between the 5.6 and 6 families.

Our Commentary ​

Okay, this is wild. We just got hit with a barrage of new models and a price war that feels like it came out of nowhere. GPT-6 Luna at half the price? That's a game-changer for developers building on these platforms. I'm genuinely curious how long this aggressive pricing can last, and what it means for smaller players in the LLM space. It's a race to the bottom, but for now, our wallets are winning.
