OpenAI announced a 20% price reduction for GPT-5.6 Terra, but it still lags behind xAI's Grok 4.5 in overall value.

Following the cut, both models share an input price of $2/M tokens. However, GPT-5.6 Terra charges $12 for output, while the frontier model Grok 4.5 charges only $6. The author notes that Grok is not only cheaper but also completes tasks in fewer steps, leading to even greater total cost savings.
