GPT-5.5 beats Opus on cost
OpenAI positions GPT-5.5 as a more capable agentic model that often reaches better answers with fewer tokens and fewer retries. The video frames that efficiency as the real story: even when sticker price is higher, lower task-level token spend can make GPT-5.5 cheaper in practice than competing frontier models.
// ANALYSIS
The pricing headline is less interesting than the workflow economics. If a model finishes the job in fewer turns, fewer retries, and less prompt bloat, the effective cost of getting real work done can drop even when list prices rise.
- –OpenAI says GPT-5.5 is more token efficient than GPT-5.4 and delivers better Codex results with fewer tokens for most users.
- –The model posts strong benchmark numbers on coding, tool use, and computer-use tasks, including Terminal-Bench 2.0, SWE-Bench Pro, and OSWorld-Verified.
- –That makes the Opus comparison matter: developers care about total task cost, not just per-token API pricing.
- –The bigger signal is category shift toward agentic efficiency, where benchmark wins and lower completion cost are increasingly the same thing.
- –For teams running long-horizon coding and research loops, token efficiency can matter more than raw benchmark bragging rights.
