GPT-5.5 Pricing Gap Looks Misleading

The post argues that GPT-5.5’s higher sticker price versus GPT-5.4 is only half the story: OpenAI says the model is more token-efficient, so the cost per completed task can be lower than the raw API rate suggests. It also points to Claude Opus 4.7’s updated tokenizer, which can inflate token usage and make Anthropic’s real-world bills look worse than headline pricing.

// ANALYSIS

Headline token pricing is a weak proxy for actual spend once model efficiency, tokenizer changes, and task length start moving in different directions.

–OpenAI says GPT-5.5 is priced at $5 per 1M input tokens and $30 per 1M output tokens, but also optimized to use fewer tokens than GPT-5.4 in practice.
–Anthropic prices Claude Opus 4.7 at $5/$25 per 1M tokens, yet its updated tokenizer can turn the same text into more tokens, which raises effective cost.
–The Reddit screenshot framing Opus 4.7 as 5-10x more expensive on ARC-AGI-2 is the more useful comparison for agentic workloads than raw list price.
–For builders, the right metric is cost per finished task, not cost per million tokens on a brochure.
–This is a reminder that vendor pricing pages understate how much implementation details can swing total billings.
