OpenAI's GPT-5.6 pricing under scrutiny as cost-per-task emerges as key metric · 1 source tracked

OpenAI has released its new GPT-5.6 model family, featuring Sol, Terra, and Luna tiers with significantly lower per-token pricing. However, the actual cost per task may be higher due to increased token usage, a phenomenon highlighted by previous analyses of GPT-5.5 and Claude Opus 4.8. Early benchmarks suggest GPT-5.6 Sol performs comparably to Claude Fable 5 on reasoning tasks but at a substantially lower cost per task, while Terra and Luna offer even greater cost reductions. AI

IMPACT New pricing models for GPT-5.6 could shift enterprise adoption based on cost-per-task efficiency rather than per-token rates.
