about me

hi! i'm leon, i live with my sambo in stockholm. i'm big on all kinds of ml research. i enjoy eating food, making food, traveling and working out.

i've got a background in software engineering but as of last year i work as a research engineer. i'm interested in: foundational models, policy learning, medical ai, and reasoning. if you're curious about my current fixations, skim the blog.

i like making things

healthy mix of research, experiments, and scratch projects.

• paper implementations in omni
• this website, including my blog
• mindex, a local semantic search engine for your mind index
• alphax, scalable + fast alphazero in jax. facilitates spmd, simd, jit-composition etc
• exploring limitations of llm-as-a-judge
• llmcontext (fork of original), a context window pressure tester of open llms
• a framework for super-resolution of clinical 4d flow mri. paper.
• alphafour , minimal alphazero for connect four in pure pytorch

i like open source

these are my favorite, some of which i contribute to.

• inference engine vllm
• finetuning with unsloth
• ggerganov's llama.cpp (#4484)
• mlx is an array framework for apple silicon (#202 #237 #456 #19 #276)
• tensor puzzles and cuda puzzles from sasha rush
• community driven ohmyzsh
• jax: the lovechild of autograd and xla

ideas

things / projects i'm thinking about lately.

• visual reasoning and visual spatial reasoning. non-text cot?
• long-form code generation benchmark.
• long-context multi-needle reasoning benchmark.
