Hosted models for the steps around your LLM: reranking, embeddings and typed decisions. Point your Cohere or OpenAI client at inference.hindsight.vectorize.io and keep your code. hs-rerank-1 and hs-embed-1 are the most accurate small open models on our benchmarks and run fast on a CPU; hs-decide-1-flash answers yes/no, pick-one and how-likely questions in 167 ms, instead of an LLM call. From $0.005 per 1M tokens, $5 free credit, open weights on Hugging Face.

Could you build this?
No The product is hosted reranking, embedding, and decision models whose claimed accuracy comes from the vendor's own trained models. Matching that requires ML research, training data, and GPU compute, beyond what vibe coding provides.
What it would actually take: A serving API compatible with Cohere and OpenAI clients is straightforward, but the differentiator is the models themselves. Building competitive small rerankers and embedders means curating large training datasets, running distillation or contrastive training, and benchmarking, which requires ML research engineers and meaningful GPU budget.
