No Training or domain-adapting a base LLM with continuous mid-training and reinforcement learning environments requires millions of dollars in compute, curated proprietary legal corpora, and ML research engineering.
What it would actually take: Requires distributed GPU training infrastructure (e.g., Megatron-LM/vLLM on H100 clusters) to run mid-training on billions of legal tokens. Additionally, building dozens of RL environments with domain-specific reward models and benchmarks requires a specialized team of machine learning research scientists and legal domain experts.
