ryan and team worked extremely hard to make gpt-5.4 great for finance

it's much improved for financial modeling and analysis, integrates directly into excel, and connects to factiva, daloopa, s&p global, and many more

it does feel like a codex moment is coming here
Excited to share that I’ve joined OpenAI to help build the future of financial intelligence.

My focus is connecting models directly to the data sources, tools, and workflows analysts use every day. My team’s first product is the Excel plugin.

After software engineering, finance will see the benefits of model improvements more acutely than almost any other field.

This is just the start for us! More to come soon!

so much of work is what I like to call the “work around work” - switching between systems, chasing context, and stitching tools together to get things done

company knowledge in chatgpt now does this for you

it can reason across tools like slack, sharepoint, google drive, answers, do analysis, and take action using a version of gpt-5 that’s optimized for working with tools & providing citations

company knowledge has changed how i use chatgpt at work more than anything we have built so far - let us know what you think!

if, like me, you are bad at shopping... chatgpt now does it for you!

we are launching instant checkout with partners @Etsy, @Shopify (soon), and others in the future

we’re also open-sourcing the agentic commerce protocol, which we co-developed with @stripe

Replying to @bradlightcap
with pro mode, you really can just ask chat to "solve for X" when it comes to analytical tasks.

it's a clear improvement over o1 preview that you can really feel in the response quality.

one thing I like appending to the prompt is "suggest some things I should be asking about ave thought of and think them through."
