{"slug": "implementation-of-gpt-2-in-pure-cmake", "title": "Implementation of GPT-2 in pure CMake", "summary": "AlpinDale released gpt2.cmake, an implementation of OpenAI's GPT-2 language model written entirely in CMake, using Q16.16 fixed-point integer arithmetic to run inference without floating-point operations. The project, licensed under BSD 3-Clause, loads the GPT-2 model from Hugging Face and generates text via CMake scripts, as demonstrated with the command 'cmake -P gpt2.cmake -DPROMPT=\"Hello\" -DN=2'.", "body_md": "GPT-2 in pure CMake, executed with Q16.16 integer arithmetic.\n\n```\nmkdir -p checkpoint\ncurl -L -o checkpoint/model.safetensors https://huggingface.co/openai-community/gpt2/resolve/main/model.safetensors\ncurl -L -o checkpoint/vocab.json      https://huggingface.co/openai-community/gpt2/resolve/main/vocab.json\ncurl -L -o checkpoint/merges.txt      https://huggingface.co/openai-community/gpt2/resolve/main/merges.txt\npython3 tools/gen_full.py\ncmake -P gpt2_full.cmake -DPROMPT=\"Hello\" -DN=2\npython3 tools/gen_tables.py\npython3 tools/gen_model.py\ncmake -P gpt2.cmake\n```\n\nBSD 3-Clause.
