No This is a trained open model with calibrated decision outputs over long contexts. Building a competitive version requires large-scale training compute, curated data, and ML research expertise.
What it would actually take: A real version requires pretraining or fine-tuning a language model with long-context support (64k tokens), building calibration on typed decision tasks, and running evaluations. It needs ML researchers, GPU clusters, and proprietary or carefully curated training data, plus a custom inference engine like the Bend-based one described.
