It's about as mundane as you'd expect, but the output of each model: https://gist.github.com/jefff/8b19458294ccef570a9f6a5b644123...

OK, I'll bite.

I tried Kimi K3, Qwen3.6 35B A3B, GLM 5.2 and Qwen3.7 Plus, chosen arbitrarily from Chinese models I could access quickly. I used your prompt exactly, and all 4 managed to produce correct functions all with the correct name. Interestingly, Kimi K3 wrote one in both C and Python, Qwen 3.6 chose Python, GLM 5.2 also chose Python, and Qwen3.7 decided to be an over-achiever and wrote functions in Python, C++, Java, and TypeScript. All correct and with the correct names.

Did you forget to include the links? I searched "TPU inference docs" but the results are either general TPU docs or just some inference examples.

It was used to great effect on the Xbox 360 until later vulnerabilities rendered it obsolete: http://beta.ivc.no/wiki/index.php/Xbox_360_Timing_Attack

It was literally just a careless use of memcmp to check an HMAC that allowed for it to work.
