OpenAi is GPT-4.1 roll outThe new non-rescue large language model (LLM) that balances high performance with lower costs, to users of Chatgpt. The company starts with its paying subscribers on Chatgpt Plus, Pro and Team, with access to the user and education in the coming weeks.
It also adds GPT-4.1 Mini, which replaces GPT-4O Mini as a standard for all chatgpt users, including those at the free level. The “mini” version offers a small -scale parameter and therefore less powerful version with similar safety standards.
The models are both available via the dropdown selection “More models” in the upper corner of the chat window in chatgpt, giving users to choose flexibility between GPT-4.1, GPT-4.1 mini and reasoning models such as O3, O4-Mini and O4-Mini-High.
Initially intended for use only by third-party software and AI developers via OpenAI’s Application Programming Interface (API), GPT-4.1 was added to Chatgpt after strong user feedback.
OpenAI Post Training Research Lead Michelle Pokrass Confirmed on X, the shift was driven by the question and wrote: “We initially intended to keep this model API alone, but you wanted it all in chatgpt 🙂 Happy coding!”
OpenAI Chief Product Officer Kevin Weil Posted on X Say: “We have built it for developers, so it’s very good at following coding and instructions – give it a try!”
An entrepreneurial model
GPT-4.1 was designed from the ground for practical usability of business quality.
Launched in April 2025 in addition to GPT-4.1 Mini and Nano, this model family prioritized developers and production use cases.
GPT-4.1 delivers a 21.4-point improvement compared to GPT-4O on the SWE-Bench-verified software engineering benchmark and a 10.5-point profit on instructional tasks in the multichallenge benchmark of the scale. It also reduces the surprises by 50% compared to other models, a users of properties praised during early tests.
Context, speed and model access
GPT-4.1 supports the standard context Windows for Chatgpt: 8,000 tokens for free users, 32,000 tokens for plus users and 128,000 tokens for Pro users.
According to developer Angel Bogado Post on X, these limits correspond to those used by earlier Chatgpt models, although there are plans to further increase the context size.
Although the API versions can process from GPT-4.1 to a million tokens, this extensive capacity is not yet available in Chatgpt, although future support has been indicated.
This extensive context capacity enables API users to feed full code bases or large legal and financial documents in the model for the assessment of multi-document contracts or analyzing large log files.
OpenAi has recognized some performancegradation with extremely large inputs, but business test cases suggest solid performance up to a few hundred thousand tokens.
Evaluations and safety
OpenAi also has one Safety evaluations Hub Website to give users access to important performance statistics in different models.
GPT-4.1 shows solid results with these evaluations. In factual accuracy tests it scored 0.40 on the SimpleQa benchmark and 0.63 on Personqa, better than different predecessors.
It also scored 0.99 on the “not unsafe” measure of OpenAi in standard refusal tests and 0.86 on more challenging instructions.
In the Strong Repject Jailbreak-Test-a academic benchmark for safety under opponents-scored GPT-4.1, however, 0.23, behind models such as GPT-4O-Mini and O3.
That said, it scored a strong 0.96 on Jailbreak prompts with people, which indicates a more robust Real-World safety under typical use.
With instructional therapy loyalty, GPT-4.1 follows the defined hierarchy of OpenAI (system about developer, developer about user messages) with a score of 0.71 for resolving system versus user message conflicts. It also performs well when protecting protected sentences and avoiding away action in tutarios.
GPT-4.1 Contextualization against predecessors
The release of GPT-4.1 comes after the research on GPT-4.5, which debuted as a research review in February 2025. That model emphasized better without supervision, a richer knowledge base and reduced hallucinations that 61.8% in GPT-4O came to 37.1%. It also showed improvements in emotional nuance and long -term writing, but many users found the improvements subtle.
Despite these profits, GPT-4.5 criticized its high price to $ 180 per million output tokens via APIs and for underwhelming performance in mathematics and coding benchmarks compared to OpenAi’s O-series models. Figures in the industry noted that although GPT-4.5 was stronger in the general conversation and generating content, it underlined in developer-specific applications.
GPT-4.1, on the other hand, is intended as a faster, more focused alternative. Although it fogs the breadth of knowledge and extensive emotional modeling of GPT-4.5, it is better tailored to practical coding assistance and adheres more reliable to user instructions.
On the API of OpenAi, GPT-4.1 is currently priced For $ 2.00 per million input tokens, $ 0.50 per million jabs and $ 8.00 per million output tokens.
For those looking for a balance between speed and intelligence at lower costs, GPT-4.1 Mini is available at $ 0.40 per million input tokens, $ 0.10 per million input tokens and $ 1.60 per million executed docks.
Google’s Flash-Lite and Flash models are available from $ 0.075- $ 0.10 per million input tokens and $ 0.30- $ 0.40 per million output tokens, less than one tenth the costs of the basic rates of GPT-4.1.
But although GPT-4.1 is priced higher, it offers stronger software engineering benchmarks and more precise instructions following, which can be crucial for Enterprise implementation scenarios that require reliability about the costs. Ultimately, the GPT-4.1 from OpenAI provides a premium experience for precision and development performance, while Google’s Gemini models rely on cost-conscious companies that require flexible model layers and multimodal options.
What it means for decision makers of companies
The introduction of GPT-4.1 offers specific benefits for business teams that manage LLM implementation, orchestration and data operations:
- AI -Senioreurs who supervise LLM implementation Can expect improved speed and instruction therapy compliance. For teams that manage the entire LLM life cycle of tuning the model to problem-solving-Biedt GPT-4.1 a more transparent and more efficient toolset. It is particularly suitable for lean teams under pressure to send performing models quickly without endangering safety or compliance.
- AI -Orchestration leads Focused on scalable pipeline design, the robustness of GPT-4.1 will appreciate the most errors caused by the user and the strong performance in the message hierarchy tests. This makes it easier to integrate into orchestration systems that give priority to consistency, model validation and operational reliability.
- Data Engineers Responsible for maintaining high data quality and integrating new tools will benefit from the lower hallucination percentage of GPT-4.1 and a higher factual accuracy. The more predictable output behavior helps to build reliable data workflows, even when team sources are limited.
- IT security professionals Task to bed in DevOps pipelines can find value in the resistance of GPT-4.1 against common jailbreaks and the controlled output behavior. While the academic Jailbreak resistance score leaves room for improvement, the high performance of the model helps to support the safe integration into internal tools produced by people.
In these roles, the positioning of GPT-4.1 makes it optimized for clarity, compliance and implementation efficiency, it is a compelling option for medium-sized companies that want to balance the performance with operational requirements.
A new step forward
While GPT-4.5 represented a scale pile in model development, GPT-4.1 focuses on use. It is not the most expensive or the most multimodal, but it provides meaningful profit in areas that are important for companies: accuracy, implementation -efficiency and costs.
This repositioning reflects a wider trend in the industry – away from building the largest models at all costs and making it more accessible and adjustable to capable models. GPT-4.1 meets that need and offers a flexible, production-ready tool for teams that try to enclose AI deeper into their business activities.
While OpenAI continues to develop its model offering, GPT-4.1 represents a step forward in the democratization of advanced AI for Enterprise environments. For decision makers who balance the power of ROI, it offers a clearer path to implementation without sacrificing performance or safety.
