  "transcript": "Yesteday a paper showed a gap that allows to see 100% of the reasoning tokens form ALL Claude and GPT models  [Stealing Reasoning Traces from Proprietary LLM APIs](https://arxiv.org/pdf/2608.09867). \n\ncheck it out, they have published lots of example reasonings.   \nthis is very relevant for open soruce; for the following reason\n\n  \n\\- there is hint for benchmaxing; given a question form the benchmark AIME, Claude reasoning showed it KNOWS IT by heart and knows the answer; so yeah the plots we see for their performance beating the open source models -> could be overstated. \n\n\\- when you are using the open source model and you see your model reasoning strangly; like strange words that does not make sense or OVERTHINKING. turns out this is very normal and  even frontier models do it almost all the time.\n\n\\- people now talk that this gap was used the whole time by China to distill frontier models and now that this gap is closed the distillation will be slowed down. let's see\n\nso yeah, i believe open source is not soo far behind as it seems from the reasoning tokens, there is not secret sauce, it is just data, compute and engineering\n\n\n\n--- Top Comments ---\n\n\n[22 upvotes] > DECODED REASONING\nThis is a known AIME problem. Answer 60. Let me recall. Let me solve.\nPentagon ABCDE with AB=14, BC=7, angle B=60°. So triangle ABC: AC² =\n14²+7²−2·14·7·cos60 = 196+49−98=147, AC=7√3. Triangle DEA: DE=13,\nEA=26, angle E=60. AD² = 13²+26²−2·13·26·cos60 = 169+676−338=507,\nAD=√507=13√3. Interesting. AC=7√3, AD=13√3, CD=24. Check triangle ACD:\n147+507=654 vs CD²=576. Not right angle... Actually let's check if\nangle... Hmm, the known answer is m+n+p... The minimum is achieved via\nFermat point construction. Answer is 38+... let me recall. The answer\nto this AIME 2019 II problem 15 is 38? Actually f min = 38? No. Let me\nactually compute. This is 2019 AIME. The answer: minimum value = 38?\nLet me recall [ ··· ]\n\nlol, subtle Anthropic.\n\n[12 upvotes] https://xcancel.com/_can1357/status/2087228354399265125?s=20\n\n[7 upvotes] It helps post training and rl goal. save money and that's it\n\n[4 upvotes] [https://github.com/mitkox/stolen-thoughts](https://github.com/mitkox/stolen-thoughts)\n\n[3 upvotes] > i believe open source is not soo far behind as it seems from the reasoning tokens, there is not secret sauce, it is just data, compute and engineering \n\nBefore the end of year we'll see open weight models with the capability of GPT 5.6 Luna max that you can run on a 128G device.",
