Which Model for Which Use Case?
Cost-Effective Premium
Both models cost $5.00/M input, but Opus 4.7 is 17% cheaper on output at $25 vs $30. For output-heavy workloads like content generation, summarization, and code review, Opus 4.7 delivers premium quality at a slightly lower cost.
OpenAI Ecosystem
GPT-5.5 integrates seamlessly with the OpenAI ecosystem — Assistants API, function calling, plugins, and tools. If your stack already runs on OpenAI and you need native ecosystem support, GPT-5.5 is the natural choice despite the slight cost premium.
Enterprise Cost Optimization
At 1M requests/month with 500K output tokens, Opus 4.7 saves $2.50/month compared to GPT-5.5. For enterprise-scale deployments, the 17% output cost difference adds up — saving $300/year at this volume, and more at higher scale.
Slightly Cheaper Output
When output volume is high, Opus 4.7's $25/M vs GPT-5.5's $30/M makes a real difference. At $17.50 for 1M input + 500K output, Opus 4.7 costs $2.50 less per month than GPT-5.5's $20.00 — a modest but consistent saving.
