Partial The harness itself (tool orchestration, vision tool wrappers, and a memory store around existing multimodal LLM APIs) is vibe-codeable. Matching the reported results across 22 benchmarks and six backbones requires research-level design iteration and significant evaluation compute.
What it would actually take: Build a Python agent loop that calls multimodal model APIs with tool schemas for grounding, segmentation, and cropping, backed by existing open vision models such as SAM or detection models. Persistent multimodal memory needs an embedding store with image and text retrieval. The hard part is the tuned memory and tool-selection logic that produces the claimed gains, which needs ML research skill and GPU or API budget for benchmark runs.
