Could you build this?
No This is a frontier multimodal foundation large language model with custom architecture and large-scale training infrastructure.
What it would actually take: Training a 1M-context multimodal LLM like DeepSeek Flash requires clusters of thousands of high-end GPUs (e.g., H100s/H800s), petabytes of curated multimodal datasets, and distributed training frameworks (Megatron-LM, DeepSpeed). It requires frontier AI research teams specializing in pre-training architectures, mixture-of-experts (MoE), custom CUDA kernels (FlashAttention variants), and high-throughput inference serving engines (vLLM/TensorRT-LLM).

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
