OpenAI's latest AI models, o3 and o4-mini, have been released with enhanced problem-solving capabilities and improved tool use, promising a step change in the ability of language models to tackle complex tasks. These reasoning models, now available to ChatGPT Plus, Pro, and Team users, demonstrate stronger proficiency in mathematical solutions, programming work, and even image interpretation. One notable feature is o3's native support for tool use, allowing it to organically utilize code execution, file retrieval, and web search during its reasoning process, a crucial aspect for modern Large Language Model (LLM) applications and agentic systems.
However, despite these advancements, the o3 and o4-mini models are facing criticism due to higher hallucination rates compared to older versions. These models tend to make up facts and present them as reality, a persistent issue that OpenAI is actively working to address. Internal tests show that o3 gives wrong answers 33% of the time when asked about people, nearly double the hallucination rate observed in past models. In one test, o3 claimed it ran code on a MacBook laptop outside of ChatGPT, illustrating how the model sometimes invents steps to appear smarter.
This increase in hallucinations raises concerns about the models' reliability for serious professional applications. For instance, lawyers could receive fake details in legal documents, doctors might get incorrect medical advice, and teachers could see wrong answers in student homework help. Although OpenAI considers hallucination repair a main operational goal, the exact cause and solution remain elusive. One proposed solution involves connecting the AI to the internet for fact-checking, similar to how GPT-4o achieves higher accuracy with web access. However, this approach raises privacy concerns related to sharing user questions with search engines.

OpenAI has launched a new series of GPT-4.1 models, including GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano. These API-only models are not accessible via the ChatGPT interface but offer significant improvements in coding, instruction following, and context handling. All three models support a massive 1 million token context window, and they have a May 31, 2024 cutoff date.
GPT-4.1 demonstrates enhanced performance in coding benchmarks, surpassing GPT-4o by 21.4% on industry benchmarks. The models are also more cost-effective, with GPT-4.1 being 26% cheaper than GPT-4o and offering better latency. The GPT-4.1 nano model is OpenAI's cheapest model yet, priced at $0.10 per million input tokens and $0.40 per million output tokens. As a result of GPT-4.1's improved performance, OpenAI will be deprecating GPT-4.5 Preview on July 14, 2025.
The GPT-4.1 series excels in several key areas, including coding capabilities and instruction following. The models have achieved impressive scores on benchmarks like SWE-bench Verified and Scale’s MultiChallenge, demonstrating real-world software engineering skills and enhanced adherence to requested formats. Several companies have reported significant improvements in their specialized applications, with GPT-4.1 scoring higher on internal coding benchmarks, providing better code review suggestions, and improving the extraction of granular financial data from complex documents.
