OpenAI has fully rolled out GPT-4.1 and GPT-4.1 mini across its ChatGPT platform, officially replacing the previous GPT-4o models for all users. This transition marks a significant upgrade that was announced Wednesday in a post on X by the company.
Key Improvements in GPT-4.1
Enhanced Coding Capabilities
GPT-4.1 excels at coding and instruction following compared to GPT-4o, making it particularly valuable for software engineers using ChatGPT to write or debug code.
Faster Response Times
While maintaining the reasoning capabilities of earlier models, GPT-4.1 delivers responses with noticeably improved speed, enhancing user experience.
Improved Accuracy
OpenAI reports that GPT-4.1 demonstrates higher accuracy across various tasks, particularly in code generation and technical problem-solving.
The rollout affects both free and paid users, with GPT-4.1 available to subscribers of ChatGPT Plus, Pro, and Team, while GPT-4.1 mini is accessible to all users including those on the free tier. As part of this update, OpenAI is removing GPT-4.0 mini from ChatGPT for all users, according to the company's release notes.
OpenAI initially launched GPT-4.1 and GPT-4.1 mini in April through its developer-facing API, drawing criticism from some AI researchers for shipping the model without a comprehensive safety report. The company defended this decision, stating that despite the improved performance, GPT-4.1 wasn't considered a "frontier model" requiring the same level of safety reporting as more advanced systems.
"GPT-4.1 doesn't introduce new modalities or ways of interacting with the model, and doesn't surpass o3 in intelligence," said OpenAI's Head of Safety Systems Johannes Heidecke. "This means that the safety considerations here, while substantial, are different from frontier models."
New Codex Agent for Developers
In a related development, OpenAI has also rolled out a new AI agent called Codex, specifically designed to help streamline software development. This agent, still in early stages with limited functionality, is intended for users with technical knowledge and can write software features, fix bugs, and run tests.
Codex runs on a version of OpenAI's o3 AI reasoning model that has been optimized for software engineering. The tool can take anywhere from one to 30 minutes to complete a task, depending on complexity, and has been designed to identify and refuse requests aimed at developing malicious software.
This move positions OpenAI to compete in the increasingly crowded market of AI-powered coding tools, alongside offerings from Microsoft's GitHub, Google, Anthropic, and specialized startups like Cursor maker Anysphere and Windsurf—the latter reportedly being eyed by OpenAI for acquisition at approximately $3 billion.
According to OpenAI's Josh Tobin, research lead on agents: "We're just seeing very fast progress in the model's ability to solve coding and software engineering problems. We see this as a particularly fast way for us to get to that agents vision."
Google DeepMind's AlphaEvolve Cracks Decades-Old Mathematical Problems
Google DeepMind has unveiled AlphaEvolve, a groundbreaking AI system that uses large language models to discover new solutions to long-standing problems in mathematics and computer science. Unlike previous AI approaches, AlphaEvolve can not only tackle unsolved theoretical puzzles but also improve a range of important real-world processes.
How AlphaEvolve Works
AlphaEvolve uses the Gemini 2.0 family of large language models to produce code for a wide variety of tasks. What sets it apart is its innovative approach: the system scores each of Gemini's suggestions, discards ineffective solutions, and refines promising ones through an iterative process until it produces optimal algorithms.
"You can see it as a sort of super coding agent," explains Pushmeet Kohli, vice president at Google DeepMind who leads its AI for Science teams. "It doesn't just propose a piece of code or an edit, it actually produces a result that maybe nobody was aware of."
Major Achievements of AlphaEvolve
-
Matrix Multiplication Breakthrough: Found new algorithms that calculate 14 different sizes of matrix faster than existing approaches, improving upon AlphaTensor's previous record for multiplying 4x4 matrices.
-
Google Data Center Optimization: Developed more efficient software for allocating jobs across Google's servers, freeing up 0.7% of Google's total computing resources—a significant improvement at Google's scale.
-
Tensor Processing Unit Efficiency: Found ways to reduce power consumption of Google's specialized TPU chips used for AI processing.
-
AI Training Acceleration: Improved the efficiency of Gemini's own training process by optimizing key computational operations.
In testing, Google DeepMind applied AlphaEvolve to over 50 different types of well-known mathematical puzzles, including problems in Fourier analysis, the minimum overlap problem proposed by mathematician Paul Erdős in 1955, and "kissing numbers" (a problem introduced by Isaac Newton). The system matched the best existing solutions in 75% of cases and found better solutions in 20% of cases.
"The result on matrix multiplication is very impressive," says Jakob Moosbauer, a mathematician at the University of Warwick. "This new algorithm has the potential to speed up computations in practice."
While AlphaEvolve represents a significant advancement in AI's ability to solve complex mathematical problems, experts note that one limitation is that it provides little theoretical insight into how it arrives at its solutions. This poses a challenge for advancing human understanding of the underlying principles.
Nevertheless, the system's ability to search for algorithms that produce specific solutions—rather than searching for the solutions themselves—makes it exceptionally powerful and widely applicable. "It makes the approach applicable to such a wide range of problems," notes Moosbauer. "AI is becoming a tool that will be essential in mathematics and computer science."
AI Regulation: GOP Proposes Controversial 10-Year Ban on State AI Rules
In a move that has sparked significant controversy, House Republicans have proposed a sweeping provision that would prohibit states from regulating artificial intelligence for the next decade. This measure was quietly tucked into a broader reconciliation bill primarily focused on healthcare changes.
Key Points of the Proposed Ban:
- Would halt all local oversight of AI by US states for 10 years
- Inserted into a bill primarily focused on Medicaid cuts and healthcare fees
- Could prevent states from using federal funds to develop AI oversight programs
- May block state initiatives that diverge from the administration's deregulatory stance
The proposal has already generated significant backlash from tech safety groups and Democrats. Rep. Jan Schakowsky (D-Ill.), the ranking member on the Commerce, Manufacturing and Trade Subcommittee, called the provision a "giant gift to Big Tech," while nonprofit organizations such as the Tech Oversight Project and Consumer Reports have warned it would leave consumers unprotected from AI harms like deepfakes and algorithmic bias.
This move aligns with the Trump administration's industry-friendly approach to AI policy, which has already seen the reversal of several Biden-era executive orders on AI safety and risk mitigation. The administration has cultivated close ties with AI industry leaders, with figures like Elon Musk serving in the Department of Government Efficiency (DOGE), entrepreneur David Sacks acting as "AI czar," and OpenAI CEO Sam Altman appearing with Trump in an AI datacenter development announcement in January.
Export Control Changes
In a separate but related development, the Department of Commerce has formally signaled its intention to rescind the Biden Administration's Framework for Artificial Intelligence Diffusion Rule, which was issued on January 15, 2025, with compliance requirements set to take effect on May 15, 2025.
This regulatory shift reflects the changing approach to AI governance and has significant implications for international technology transfer and AI development. Industry observers are closely watching how these policy changes will impact global AI competition and cooperation.
State-Level AI Legislation
Despite the federal proposal to limit state-level regulation, state legislatures have been active in addressing AI governance. According to the National Conference of State Legislatures, in the 2025 legislative session alone, at least 45 states and Puerto Rico have introduced at least 550 AI bills, reflecting widespread interest in establishing guardrails for this rapidly evolving technology.
The tension between federal deregulation and state-level initiatives highlights the complex challenge of governing AI technologies that simultaneously promise significant benefits and pose potential risks to consumers, businesses, and society.
AI Business Impact: Leaders Maintain Heavy Spending Despite Challenges
AI industry leaders are confronting a new reality characterized by excessive hype, high expenses, diverging strategic interests, and questions about the headroom for cutting-edge AI such as reasoning models. Despite these challenges, companies continue to make significant investments in AI development and infrastructure.
Meta Delays "Behemoth" AI Model
Meta has reportedly postponed the release of its flagship AI model, "Behemoth." Initially planned for an April release alongside LlamaCon, then pushed to June, the launch is now delayed until at least fall 2025. The delay is attributed to concerns about whether the model has achieved significant enough performance improvements compared to previous iterations.
This development reflects a growing trend in the industry where companies are becoming more cautious about releasing new models that don't demonstrate substantial advances over existing technology. Meta is not alone in facing such challenges, as other major AI labs have also encountered difficulties in building more advanced systems that justify the tremendous resources required.
Enterprise AI Adoption

With the summer travel season approaching, Google has rolled out new updates for Search, Maps, image-based search tool Lens, and its Gemini AI to provide travelers with enhanced ways to book, plan, and experience trips. These include AI Overviews, a hotel price-tracking tool, and Lens features that allow users to take a picture of virtually anything and build an itinerary around it.
"Travelers are finding these features incredibly useful for accessing information and asking new kinds of questions, helping them save time and focus on enjoying their destination," a Google spokesperson said.
Expedia and OpenAI Collaboration
Expedia is partnering with OpenAI's Operator and Microsoft's Copilot Actions to automate travel booking tasks. Last week, the company launched Expedia Trip Matching, currently available to early access users on Instagram, which allows travelers to build an itinerary based on an Instagram Reel and then book directly on Expedia.
The Future of AI in Travel
The use of agentic AI in travel is being designed to make decisions and take actions autonomously, adapting to changing environments rather than just reacting to user inputs. This represents both an opportunity and a threat to major travel industry players who could be disintermediated.
"The presumption is that AI agents can research, plan and book travelers' vacations autonomously, thus circumventing online travel agents and other intermediaries," Starkov explained. "This isn't about AI assistants anymore; it's about fully autonomous agent networks that execute complex workflows in real time."
In the future, AI agents representing travelers may negotiate with AI agents representing airlines, hotels, and destination providers to secure the best deals and personalized experiences for consumers.

AI Security Threats: FBI Warns of AI-Powered Impersonation
The FBI has issued a warning about a threat campaign in which malicious actors are impersonating senior U.S. officials using malicious text messages and AI-generated voice messages. These sophisticated social engineering attacks target current and former federal and state officials and their contacts.
According to the FBI alert released Thursday, the messages are designed to establish a rapport with individuals who might then provide access to personal accounts. These social engineering techniques could be leveraged to reach additional contacts and gain access to sensitive information or funds.
Rise in AI Voice Cloning
This campaign highlights the growing trend of "smishing" (SMS phishing) and "vishing" (voice phishing) attacks, often leveraging AI-powered voice cloning technology. According to a report by CrowdStrike, the use of AI-based voice cloning surged by 442% between the first half of 2024 and the second half of the year.
"Criminals can use it to social engineer a situation, usually for financial gain. An example: malicious actors clone a boss's voice and use it to request that the CFO pay off an unexpected invoice," explained Leah Siskind, director of impact and AI research fellow at the Foundation for Defense of Democracies.
Threat actors are now able to create realistic impersonations of public figures with surprisingly accurate voice replications after analyzing as little as a few minutes of audio, according to Aaron Rose, a security architect at Check Point Software Technologies.
Prevention and Protection
Protecting Against AI-Powered Social Engineering
-
Verify through alternate channels: When receiving suspicious communications, contact the purported sender through a different, established communication channel.
-
Establish verification procedures: Create pre-arranged verification questions or code words for sensitive communications.
-
Employee training: Regularly educate staff about the latest social engineering tactics, including AI-powered voice cloning threats.
-
Multi-factor authentication: Implement strong MFA to protect accounts even if credentials are compromised.
-
