Appreciated the response! I noticed the same when I ran tau2 myself on gpt-5 and 4.1, where gpt-5 is really good at looking at tool results and interleaving those with thinking, while 4.1/o3 struggles to decide the proper next tool to use even with thinking. To some extent, gpt-5 is too good at figuring out the right tool to use in one go. Amazing progress.
Correct, and with reasoning, the ratio is totally off. As others have pointed out, actual usage is way higher (much more than 3-5x) than the estimation in the article, which is probably for very trivial users.
The estimation for output token is too low since one reasoning-enabled response can burn through thousands of output tokens. Also low for input tokens since in actual use there're many context (memory, agents.md, rules, etc) included nowadays.
While there're interesting findings here, https://arxiv.org/pdf/2502.03373 (also with a lot of good findings) suggested some contradicting theory on the critical mass of training process/data for the sake of reasoning capability.
Strangely, deepseek has been always a prominent name in open source LLM community since last year, with their repos and papers - https://github.com/deepseek-ai. Nothing of it is really quiet except that they probably burn 1% of marketing money compared to other China LLM players.
On personal anecdotes, I've used the same internet identity across all platforms and it's not hard to locate my real life identity from there...since like 20 years ago when I got on the internet. So all the good reputation and bad reputation followed me through, and surprised me in best and worst way.
There're times when I wished I had concealed myself saying certain things (or just haven't said it), and times when I felt the joy of recognition when people connected dots about me and became closer friend. Now as I'm getting old, it's just a habit, no longer about risks or rewards.
Yet, both younger me and older me will probably be very indecisive about doing this if they've never done it and are told about all the fortune/misfortune this has brought to me, including meeting my wife and thinking about suicides.
