Span-01 vs. Liquid d1

Span-01 represents a cutting-edge hyper-parallel reasoning classifier designed to detect complex patterns within large production traces in a single forward pass. Rather than generating tokens sequentially, it evaluates natural-language behavior definitions and outputs direct probabilities that indicate whether a specific behavior is present, absent, or unobservable. The model begins with a foundational training phase focused on general classification reasoning through Reinforcement Learning with Human Feedback (RLAIF), which is followed by fine-tuning aimed explicitly at behavior detection. This training methodology empowers Span-01 to effectively leverage previously unseen definitions for both new behaviors and diverse domains, thereby circumventing the constraints of a fixed taxonomy. During inference, its hyper-parallel definition branches are capable of assessing multiple behaviors at once against the same trace context. Additionally, the use of hybrid attention enhances its ability to reason over lengthy and complex inputs. Engineered for the scrutiny of production environments, Span-01 emphasizes safety, reliability, grounding, agent behavior, and response quality while tackling challenges like jailbreak and prompt injection detection alongside privacy and confidentiality issues. This innovative methodology not only makes Span-01 a noteworthy milestone in the domain but also paves the way for more efficient and thorough investigations into intricate behaviors, ultimately leading to improved decision-making processes. As a result, its deployment could significantly enhance operational standards across various industries.

d1 is the first decision model introduced by Liquid AI, which offers answers to structured questions about a given situation by utilizing probabilities rather than generating text responses. This innovative model efficiently processes unstructured data, such as textual and visual inputs, along with one or more inquiries in a single, cohesive forward pass, yielding probabilities without producing traditional output tokens. It supports three specific question formats: noul for simple yes-or-no choices, choice for selecting from a set of labels with their corresponding probabilities, and score for evaluating inputs on a ranked scale using probability metrics. Additionally, d1 is capable of processing multiple questions at once within a single query, thereby boosting its effectiveness in real-time decision-making scenarios. Liquid AI demonstrates the versatility of d1 across various applications, including the filtering of support tickets, exploring code repositories, intelligently categorizing documents into folders, managing websites, summarizing agent context, inspecting industrial parts, and even participating in games based on screenshots. This wide array of applications showcases not only the model's adaptability but also its potential to transform decision-making processes across different industries, emphasizing a notable leap forward in the realm of decision-making technologies.
