LightCell Energy · AI + physics, one stack

The stack that builds a man-made star.

LightStack is LightCell Energy's AI and software stack — the minimalist frontier-model tooling we run on, and the live physics it produces. reading is doing.

The Na converter — 2D, radiating across the gap

A real solve, in your browser — not a cartoon. Fuel burns in the hot core; no conduction to the PV; energy crosses the vacuum gap as matched line/band light (useful) + broadband thermal (parasitic). The 2D field runs bright on the axis, cold at the silicon wall — excitation radiating across the gap, energy-conserving. Drive the conditions; the field redraws live.

The AI tools

Strip the frontier model to the model; keep only what earns its place; point it at the hardest physics on earth. Honest about what's shipped vs in build:

freshclaudeshipped

a bottle of Claude, stripped. ~23,800 tokens of harness cruft on cold start → 46. same weights, no scaffold — the cleanest surface that still does frontier work.

the tribunalshipped

claude + gemini + grok, majority vote, catching the one model fooling itself. rust, in-process.

non-equilibrium detectiveshipped

an adversarial validator whose only job is to catch the model smuggling the convenient equilibrium assumption into a device that has none. a confident word is not a verification.

proof_gateshipped

blocks "fixed / shipped / working / verified" after a mutation with no verification artifact in the same turn. catches real ones, daily.

claudeflareshipped

255 cloudflare zones, one skill. workers / kv / dns / analytics.

pylonshipped

rust statusline, guard, state.

OpenCretinshipped

an open CRETIN-class NLTE radiation-transport code — against the export-controlled tool that walls the methodology off. rust core, 19 tests green, running WASM kernels. civilian physics, free.

les gros chatonsbuilding

open weights, next: a fused council of the best open models, kept warm by the GPUs that run it. a model you don't own can be made nervous by whoever holds it.

we walk out of an encyclopedia, not a comic book. the application is the benchmark — one action becomes one eval row. build the future. make it free. repeat.
