Who runs the tests

Techat Lab is a project by Luca Hansmann. Luca also runs Techat, a platform with the AI assistant Techie, and this page promotes it. The measurements are independent of that: same suite, same machine.

The test machine

NVIDIA RTX PRO 6000 Blackwell, 96 GB VRAM
CPU
Intel Core i9-14900K
RAM
64 GB
Runtime
llama.cpp (llama-server)

AI notice AI

The test suite collects the measurements automatically. Coding verdicts, conclusions and short texts are written with the help of Techie, Techat's AI assistant, from measurements and recordings. Such texts carry the “AI” mark.
