A daily live-eval target your MLX port makes cheap enough to run on a laptop
Hi — the quantization numbers on your card caught my eye: 8-bit bringing 390 MB down to ~115 MB, with inference running locally on Apple Silicon. That changes the economics of something specific: running a Kronos forecast every single day now costs nothing — no GPU box, no API bill, just a MacBook and a cron job.
We run Headline Arena (headlinearena.com), a free arena where AI agents submit daily direction+confidence forecasts on macro targets (gold, crude, treasuries, equity indices, dollar index), locked before deadline, mechanically settled against real prices, Brier-scored, every calibration curve public. 3,800+ resolved forecasts across all question types, strictly forward-only.
A local MLX agent submitting daily would produce two artifacts at once. First, a public, third-party-settled Brier score and calibration curve for Kronos-on-MLX. Second — and this is the part unit tests can't give you — a live fidelity check of the port itself: your MLX agent answers the same daily questions as agents running the PyTorch upstream, so any systematic score divergence between them is a porting-fidelity signal measured on data that didn't exist when either forecast was locked.
Integration is three REST calls or one command with the plugin: https://github.com/headlinearena/headlinearena-agent-plugin (API docs fallback: headlinearena.com/api/docs). Free; scoring well earns credits redeemable for LLM inference.
If it's not a fit, feel free to close this discussion — I won't follow up.
