The Builder
“Name the primitive.”
Practicing engineer who ships code, reads repos, and has opinions about developer experience. Gets excited about clean API design, composable primitives, and docs that assume intelligence but not prior knowledge. Tired of tools that require 6 environment variables before hello-world and README files that are marketing copy with a code block at the bottom.
Gets excited about
- +Clean APIs where the right thing is the easy thing
- +Composable primitives over wholesale platforms
- +Performance from thinking, not hardware
Tired of
- -Landing pages that don't say what the thing does
- -"AI-powered" as a feature, not an implementation detail
- -Frameworks that wrap three API calls and call themselves a platform

Open reconstruction of Claude Mythos using Recurrent-Depth Transformers
“The RDT architecture is backed by published research — this isn't pure speculation. The code is clean, the model configs cover 1B to 1T scales, and the Flash Attention 2 + MoE integration is production-quality. Even if the Mythos attribution is wrong, the architecture itself is worth experimenting with for inference-efficient reasoning.”
Google's on-device multimodal model: text, image, and audio in 4B params
“Native audio + vision + text at 4B effective params that actually runs on a phone is genuinely impressive engineering. The MediaPipe integration means I can drop this into an Android app in an afternoon. The nested parameter sets are clever — it's like getting a free speed tier based on query complexity.”
399B open-weight reasoning model, 13B active params, Apache 2.0
“A #2 benchmark result from a 30-person startup under Apache 2.0 is legitimately shocking. The sparse MoE architecture means you can run 399B at a reasonable cost — and $0.90/M output is almost too cheap to believe for this performance tier. This is going in our eval suite immediately.”
