OpenAI has reduced prices for two versions of its GPT-4 Turbo model, with Luna seeing an 80% cut and Terra a 20% cut. The company also introduced a new 'fast mode' offering a 2.5x speed boost. These changes indicate OpenAI's strategy to compete on cost and efficiency.
“Effective Thursday, the two smaller versions of GPT 5.6 saw a price cut, with Luna down 80% to $1.20 per million output tokens and Terra down 20% to $2 per million output tokens.”
“Sol prices were held steady, but Open AI introduced a new fast mode with a 2.5X speed boost.”
“This shows a clear awareness that cost is a vector that they need to compete on, and that more efficient models are going to increasingly have a more complicated competitive landscape.”
