In line with developer Angel Bogado posting on X, these limits match these utilized by earlier ChatGPT fashions, although plans are underway to extend context dimension additional.
Whereas the API variations of GPT-4.1 can course of as much as a million tokens, this expanded capability is just not but out there in ChatGPT, although future help has been hinted at.
This prolonged context functionality permits API customers to feed complete codebases or giant authorized and monetary paperwork into the mannequin—helpful for reviewing multi-document contracts or analyzing giant log recordsdata.
OpenAI has acknowledged some efficiency degradation with extraordinarily giant inputs, however enterprise check circumstances recommend strong efficiency as much as a number of hundred thousand tokens.
Evaluations and security
OpenAI has additionally launched a Security Evaluations Hub web site to present customers entry to key efficiency metrics throughout fashions.
GPT-4.1 exhibits strong outcomes throughout these evaluations. In factual accuracy checks, 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 checks, and 0.86 on more difficult prompts.
Nevertheless, within the StrongReject jailbreak check—an instructional benchmark for security below adversarial situations—GPT-4.1 scored 0.23, behind fashions like GPT-4o-mini and o3.
That mentioned, it scored a robust 0.96 on human-sourced jailbreak prompts, indicating extra strong real-world security below typical use.
In instruction adherence, GPT-4.1 follows OpenAI’s outlined hierarchy (system over developer, developer over consumer messages) with a rating of 0.71 for resolving system vs. consumer message conflicts. It additionally performs nicely in safeguarding protected phrases and avoiding resolution 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 lowered 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 value — as much as $180 per million output tokens through 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 generally dialog and content material era, it underperformed in developer-specific functions.
Against this, GPT-4.1 is meant as a sooner, extra targeted various. Whereas it lacks GPT-4.5’s breadth of data and in depth emotional modeling, it’s higher tuned for sensible coding help and adheres extra reliably to consumer directions.
On OpenAI’s API, GPT-4.1 is presently 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 steadiness between pace and intelligence at a decrease value, GPT-4.1 mini is out there 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 fashions 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 increased, it gives stronger software program engineering benchmarks and extra exact instruction following, which can be important for enterprise deployment situations requiring reliability over value. In the end, OpenAI’s GPT-4.1 delivers a premium expertise for precision and growth efficiency, whereas Google’s Gemini fashions attraction to cost-conscious enterprises needing versatile mannequin tiers and multimodal capabilities.
