🏠 eightman999

I'm an information engineering student in Japan building local AI systems, LLM inference tools, coding-agent workflows, and apps.

My projects usually start with a question: Can this actually work? I enjoy testing ideas on everything from Apple Silicon to aging GPUs, then publishing implementations, measurements, and their limitations.

• 🧠 Persistent/distributed cognition, memory, and AI agent architectures
• ⚡ Local LLM inference, speculative decoding, and multi-GPU performance
• ♻️ Legacy-GPU software, OpenCL 1.1, and salvaged computing
• 🇯🇵 Japanese tokenizers, fiction-oriented language models, and long-context evaluation
• 🧪 Reproducible benchmarks, regression tests, experiment records, and honest failure analysis
• 🛠️ macOS / Android / web apps, creative software, and developer tools

日本語でも活動しています。**「動くところまで作り、実測し、再現できる形で公開する」**ことを大切にしています。

Additional experiments: NavSpec (structured naval-spec generation and validation) and Open Jev Core ML (experimental Apple Silicon inference, with documented limitations).

I work with the 地元のLLM community on local-AI tooling, including ScrapGpuLibrary, rustdsh, and the community Bench of Us reports.

I also contribute to J-LLM on Hugging Face, sharing Japanese models, tokenizers, and other experimental artifacts. The J-series v2 collection covers multiple tokenizer vocabulary sizes.

Projects vary in maturity. A prototype, a benchmark, or a successful test is not a production guarantee.

• 🌸 Ourin / 桜鈴 — macOS-native Ukagaka-compatible baseware, built with Swift and native SHIORI runtimes.
• 🔍 DiffLoupe — a macOS-native folder/file diff tool inspired by WinMerge.
• ✒️ Singleline JP Font — Japanese centerline fonts and 1-bit assets; the expanded v2 family is still a release candidate with proofreading in progress.
• ⚓ NavSpec — structured fictional naval specification generation, constraints, and regression evaluation.
• 🧠 Open Jev Core ML — experimental Core ML / Apple Silicon conversion and benchmark results, including negative findings.
• 🛠️ HOI4 Modding AI Agent Skills — reusable references and agent skills for game modding.
• 📱 WattTime — a published Android microwave heating-time converter built with Kotlin.

I use AI coding agents heavily, but try to keep claims separate from measurements: CI, test results, raw outputs, hashes, experiment manifests, and failure records matter more than "it seems to work".

I also run local experiments across Apple Silicon, CUDA, and legacy OpenCL systems, including mixed-generation NVIDIA GPUs, so hardware constraints are treated as part of the research rather than an afterthought.
