Updated models in Senler — more choice for different tasks
GPT-6 Sol is updated to GPT-6.1 Sol, Opus to 5.5, and we also added Sonnet 5.5 and Grok 4.7.
🌙 Meanwhile, GPT-6 Luna remains the best pick for most tasks — it is significantly faster and cheaper than the more powerful models.
When the task is hard and quality matters more than cost, you now have options to switch to. Relative to Luna on the Artificial Analysis thinking index: GPT-6.1 Sol +60%, Opus 5.5 +70%, Sonnet 5.5 +57%, Grok 4.7 +53%.
Extra “thinking” comes at a price: in our tests Sol was 17.5× more expensive than Luna, Grok 48.7×, Sonnet 85.1×, and Opus 165.4×.
They also took longer than Luna to complete the tasks.
