OpenAI launches tiered GPT-5.6 family, performance claims debated

By PulseAugur Editorial · [1 sources] ·

OpenAI has released GPT-5.6, not as a single model, but as a tiered family of three: Sol, Terra, and Luna. Sol is designed for the most complex tasks and is the most expensive, while Terra is positioned as a cost-effective default option comparable to the previous generation's flagship. Luna is optimized for high-volume, rapid tasks at a lower cost.

    GPT-5.6 vs the Frontier. The Comparison Depends on Which Benchmark You Look At

    <p><em>OpenAI didn’t ship one new model. It shipped three, Sol, Terra, and Luna, and then claimed a state-of-the-art win on the one benchmark it chose to highlight. Look at the benchmarks OpenAI didn’t show, the ones a competitor still leads, and the “who’s best” picture stops be…
