OpenAI recently announced a tailored service for the financial sector, aimed at company research, financial data analysis and presentation generation. Created with design partners Morgan Stanley and Evercore, ChatGPT for Financial Services uses GPT-6 Astra and competes with financial AI offerings from Anthropic and Google. Looking at the immediate effects of OpenAI’s new financial offering, the benefits of AI integration are clear: higher productivity and greater efficiency. The downside is equally important: job security.
ChatGPT for Financial Services differs from the traditional consumer interface through its direct access to financial data. Through connections with LSEG, Daloopa, Crunchbase and PitchBook, the service analyses information ranging from financial statements to earnings transcripts. It also connects to employees’ existing data subscriptions. Similar to the productivity gains created by Microsoft Excel, this new generation of financial AI has the potential to reshape the work of junior analysts and bankers.
However, as the rapid rise of AI continues into unfamiliar territory, its first generation of users faces risks and side effects that remain poorly understood.
OpenAI’s expansion into tailored enterprise services stems partly from the growing importance of enterprise revenue within its business. As the company develops more tailor-made services beyond financial services, the effects of AI assistance on employee performance, learning and decision-making deserve greater attention.
One concern is cognitive debt, where repeated reliance on external AI assistance reduces the amount of cognitive work performed by the individual. At first, automation appears useful. A junior analyst might use AI to help construct a financial analysis, summarise an earnings call or draft a presentation. Over time, however, repeated dependence on AI raises a more important question: whether employees still develop the underlying skills required to perform those tasks independently.
A study from MIT examining AI assistance in essay-writing tasks raised concerns about this issue. The researchers examined whether repeated LLM use affected memory, neural engagement and the way participants approached written work. The findings do not prove that AI broadly damages cognitive ability, but they suggest that the way people use AI matters.
The study divided participants into three groups: LLM, Search Engine and Brain-only. Focusing on the LLM and Brain-only groups, the LLM group had access to AI assistance, while the Brain-only group worked without AI or a search engine. The Brain-only group showed stronger and more widely distributed neural connectivity, while the LLM group produced essays with greater within-group similarity in language and topic structure. The LLM group also showed weaker recall of its own work.
These findings suggest an important trade-off. AI assistance improves speed and reduces effort, but excessive dependence during the learning process risks reducing active engagement with the task. For junior financiers, this matters because financial judgement develops through repeated exposure to difficult analysis, uncertainty and decision-making.
The study later reversed the conditions. Participants who had previously worked without AI were given LLM access, while those who had relied on an LLM completed the task without assistance. The Brain-to-LLM group showed stronger memory recall and greater re-engagement of prefrontal and other neural networks. In contrast, the LLM-to-Brain group showed weaker connectivity across several alpha and beta networks.
This raises an important question: how should firms design AI use around the Brain-to-LLM pattern rather than the LLM-to-Brain pattern?
For experienced analysts and bankers, this issue is less straightforward. Many have already developed the core analytical skills behind financial analysis through years of practice. They understand how to build a valuation, interpret a balance sheet and assess the logic behind an investment thesis before introducing AI into the process.
For incoming analysts, the situation differs. If AI performs too much of the analytical work before junior employees develop those foundations, external assistance risks shaping how they think before those skills are fully formed. The MIT study suggests that people who begin without AI and introduce it later remain more cognitively engaged than those who rely on AI first and remove it later.
This matters in finance because strong analysts need more than speed. They need judgement, pattern recognition, scepticism and the ability to generate original interpretations from incomplete information. AI often helps users remain close to the task or prompt provided. Human analysts still need to question assumptions, identify what others have missed and form views that do not simply reflect the most statistically common response.
Enterprises should embrace AI for its productivity and efficiency benefits. However, they also need to rethink how incoming employees are trained. Junior analysts should first learn how to build, analyse and defend their own work before relying heavily on AI assistance.
The defining skill in this new environment will not be the ability to use AI quickly. It will be knowing when to use it, when to challenge it and when to think without it. The preservation of individual judgement, taste and financial instinct will separate analysts who use AI as a tool from those who become dependent on it.
