About

Span-01 is a hyper-parallel reasoning classifier built to detect complex behaviors across long production traces in a single forward pass. Rather than generating tokens sequentially, it reasons over natural-language behavior definitions and returns direct probabilities for present, absent, and not_observable. The model is trained for general classification reasoning with RLAIF before being specialized for behavior detection, allowing it to apply previously unseen definitions to new behaviors and domains instead of relying on a fixed taxonomy. At inference time, hyper-parallel definition branches evaluate multiple behaviors against the same trace context simultaneously, while hybrid attention helps preserve reasoning over long, complex inputs. Span-01 is designed for production monitoring across safety, reliability, grounding, agent behavior, and response quality, including jailbreak and prompt injection detection, privacy, and secrets.

About

Twigg is a context-management tool designed for long-term interactions with large language models that replaces linear chat threads with a visual, branching tree of conversation nodes, giving users control over what context is sent to the model. You can explore alternate directions by instantly creating new branches from any point, cutting or copying nodes, deleting or moving content to optimize the prompt context, and thus improve performance while managing complexity. The interface provides a dashboard tracking token usage per model and shows credit consumption transparently. By controlling context at the node level, Twigg helps reduce unnecessary tokens and supports the concurrency of ideas without cluttering your main workflow. Compatible with major models (via BYOK support) and designed for extended projects, Twigg essentially acts as “Git for LLMs”, enabling versioning, branching, and precise context management for conversational AI workflows.
