Description

Antaeus serves as a semantic policy engine designed for developers tasked with assessing human-written rules related to language, context, intent, or exceptions. It features an open-source core built in Go and a command-line interface that can load policy artifacts in YAML or JSON formats, validating these against versioned schemas while executing named regression tests. The evaluation process yields clear outcomes such as allow, review, deny, or failure, accompanied by policy identification and evidence for the decisions made, while leaving the responsibilities of authentication, authorization, and any consequential actions to the application itself. Developers have the option to operate a deterministic, credential-free local workflow or utilize an experimental hosted dashboard and API for managing policies and evaluating various inputs. Additionally, there is an experimental OpenAI evaluator available for use. It is important to note that Antaeus is still in its early stages; thus, the capacity of the hosted service is limited and does not come with a production-level service level agreement (SLA), which may affect reliability during high-demand situations.

Description

Tev1 is a rapid decision-making and classification model developed by Together AI, which has been fine-tuned from Qwen3.5 4B. Its user-friendly interface allows for the input of a state, a question, and between 2 to 24 labeled choices, enabling the model to output a single letter that can be mapped back to a semantic key by software. This design is particularly beneficial for various production tasks, such as managing support ticket routing, assessing automated returns, enforcing policy guidelines, sentiment analysis, document categorization, and integrating precise decision-making steps into larger agent workflows. With a parameter count of 4.7B and a 32.8K-token context window, the model operates with non-thinking generation to ensure fast and reliable classification. It has been trained on a diverse set of 37,840 examples covering areas such as intent detection, boolean comprehension, sentiment evaluation, policy application, as well as categorizing news and academic papers. The recommended configuration suggests using a temperature setting of 0 along with a minimal output budget, ensuring that the responses are both consistent and straightforward to interpret. In summary, Tev1 stands out as a versatile tool that efficiently addresses a wide range of classification needs.
