GPT-5.5 Runs Cheaper Than Sticker Price

The post argues that GPT-5.5’s higher list price can still translate to lower task cost because it uses fewer tokens in practice. It also says Claude Opus 4.7 looks less favorable once its tokenizer changes and higher token usage are factored in.

// ANALYSIS

Hot take: this is a classic “price per token” trap, not a true cost comparison.

–GPT-5.5 can win on total task cost even if its listed API price is higher than GPT-5.4, because efficiency and shorter completions matter.
–Opus 4.7’s stronger headline pricing looks less favorable once you factor in Anthropic’s tokenizer change and the resulting token inflation.
–The right comparison is cost per completed task on the same workload, not raw input/output token rates.
–On benchmark-style workloads like ARC-AGI-2, the practical gap can make Opus look several times more expensive than GPT-5.5.
