Models
Fine-tunes I train on my DGX Sparks and publish on Hugging Face in GGUF and EXL3 quants, listed straight from the Hugging Face profile.
Recipes
The lmswitch configs I actually run on DGX Spark (llama.cpp, vLLM, ExLlamaV3) and the reproducible recipe behind every benchmark.
Benchmarks
Live LLM benchmarks on DGX Spark: parallel agent sessions, tokens/sec and latency per model and runtime, with open data.
Grok bots
Grok bots that work for you on X: they plug into your workflows, automate the busywork and deliver results right in your timeline.
Tools
lmswitch, RepoBeagle repo scanning, murmur local dictation, SolDecode, a Zed token counter and a 3D-printable DGX Spark rack.
Lab
Experiments: the DGX Spark bench, a tokens/sec simulator and the Voxel Bridge Challenge.
Odin Scan
A continuous AI security auditing scanner for smart contracts: a deep AI audit agent plus deterministic rules across Solana, EVM, CosmWasm and Cosmos SDK, with a GitHub Action that screens every pull request.
