Similarity graph

Local clusters rerank extracted product concepts and description terms. The generated graph remains the fallback for sparse descriptions: offline reciprocal product-similarity graph: extracted concepts + description terms + bounded category/affiliation boosts. Minimum fallback score: 0; max competitors: 6.

Lucidic AI

match 53

Lucidic emulates model training without changing model weights. The last decade made models intelligent, but intelligence is not the same as experience. Humans do not get better by memorizing thousands of examples; we build learning systems around ourselves: skills, memories, critique, practice, tools, and guidance. And every person learns differently because every task is different. Lucidic brings that idea to AI agents by training a custom learning system for each agent, so it learns what to r

OpenPipe

match 49

OpenPipe is an SDK that abstracts away fine-tuning custom models. We capture your existing provider’s prompt-completion pairs in the background and use them to create a new model that is faster, cheaper and often more accurate than the original.

Integrated Reasoning

match 41

Integrated Reasoning builds efficient computer processors that are tailored to the memory access patterns of Karp's 21 NP-complete problems. We’re making it 100x - 10,000x faster to perform computations like scheduling airline pilots or optimizing packing layouts for shipping containers.

Datasaur

match 38

Datasaur builds intelligent, optimized, human-centric LLM/NLP tools. If you're still using Excel or maintaining your own in-house tools, Datasaur can offer you significant cost-savings and improve the quality of your training data. We provide tools custom-built for power users. Our built-in intelligence helps augment your human labelers and avoid costly mistakes; our workforce management tool allows you to assign projects to and cross-validate the results from multiple labelers to ensure you can
