OpenAI has additionally launched a Safety Evaluations Hub web site to present customers entry to key efficiency metrics throughout fashions.
GPT-4.1 exhibits stable outcomes throughout these evaluations. In factual accuracy assessments, it scored 0.40 on the SimpleQA benchmark and 0.63 on PersonQA, outperforming a number of predecessors.
It additionally scored 0.99 on OpenAI’s “not unsafe” measure in commonplace refusal assessments, and 0.86 on more difficult prompts.
Nonetheless, within the StrongReject jailbreak check—a tutorial benchmark for security underneath adversarial circumstances—GPT-4.1 scored 0.23, behind fashions like GPT-4o-mini and o3.
That mentioned, it scored a powerful 0.96 on human-sourced jailbreak prompts, indicating extra sturdy real-world security underneath typical use.
In instruction adherence, GPT-4.1 follows OpenAI’s outlined hierarchy (system over developer, developer over person messages) with a rating of 0.71 for resolving system vs. person message conflicts. It additionally performs effectively in safeguarding protected phrases and avoiding answer giveaways in tutoring situations.
Contextualizing GPT-4.1 towards predecessors
The discharge of GPT-4.1 comes after scrutiny round GPT-4.5, which debuted in February 2025 as a analysis preview. That mannequin emphasised higher unsupervised studying, a richer information base, and decreased hallucinations—falling from 61.8% in GPT-4o to 37.1%. It additionally showcased enhancements in emotional nuance and long-form writing, however many customers discovered the enhancements refined.
Regardless of these good points, GPT-4.5 drew criticism for its excessive worth — as much as $180 per million output tokens by way of API —and for underwhelming efficiency in math and coding benchmarks relative to OpenAI’s o-series fashions. Trade figures famous that whereas GPT-4.5 was stronger usually dialog and content material era, it underperformed in developer-specific functions.
In contrast, GPT-4.1 is meant as a quicker, extra targeted different. Whereas it lacks GPT-4.5’s breadth of information and in depth emotional modeling, it’s higher tuned for sensible coding help and adheres extra reliably to person directions.
On OpenAI’s API, GPT-4.1 is currently priced at $2.00 per million enter tokens, $0.50 per million cached enter tokens, and $8.00 per million output tokens.
For these in search of a stability between velocity and intelligence at a decrease price, GPT-4.1 mini is obtainable at $0.40 per million enter tokens, $0.10 per million cached enter tokens, and $1.60 per million output tokens.
Google’s Flash-Lite and Flash models can be found beginning at $0.075–$0.10 per million enter tokens and $0.30–$0.40 per million output tokens, lower than a tenth the price of GPT-4.1’s base charges.
However whereas GPT-4.1 is priced larger, it affords stronger software program engineering benchmarks and extra exact instruction following, which can be crucial for enterprise deployment situations requiring reliability over price. In the end, OpenAI’s GPT-4.1 delivers a premium expertise for precision and improvement efficiency, whereas Google’s Gemini fashions attraction to cost-conscious enterprises needing versatile mannequin tiers and multimodal capabilities.
