OpenAI's GPT-6 Sol and Luna halve prices but barely improve performance, report finds
The Decoder · rss · 2026-09-23
The Decoder reports OpenAI launched GPT-6 Sol and Luna, two cheaper models delivering their predecessors' performance at half the token price, directly targeting Anthropic's pricier offerings.
- Independent analyses find little gain in actual intelligence — the price cut is the main selling point.
- The report suggests OpenAI likely didn't anticipate Anthropic's simultaneous Opus 5.5 launch, intensifying the rivalry.
