Span-01
Respan
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.Starting Price: $199 per month -

18
Shieldstral
Mistral AI
Shieldstral is a 3B open-weights, policy-adaptive multimodal safety classifier designed to evaluate text, images, and text-plus-image content using policies defined at inference time. Instead of relying on a fixed taxonomy of harm categories, it frames moderation as a binary question-answering task: users provide an instruction describing the evaluation context and strictness, a yes-or-no safety question, and the content to judge. The model reads the “yes” and “no” logits and converts them into a continuous, calibrated safety score, allowing applications to threshold or rank results by confidence rather than depend on a single discrete label. This formulation unifies prompt classification, response moderation, refusal detection, toxicity detection, and multimodal safety in one interface, while letting teams adapt policies without retraining the model. Shieldstral can evaluate prompts, responses, prompt-response pairs, images, and images with accompanying text. -

ID8S GEO IQ
ID8S AI, Inc.
Search is splitting in two. People still type queries into Google, but they more often ask ChatGPT, Claude, Perplexity, and Google AI Overviews, and those engines answer by citing a small set of sources. If your page is not one of them, you are absent from the answer, and standard analytics will not tell you why. GEO IQ is the AI Search Visibility Platform. Point it at any URL and it returns an AI Search Visibility Score across three areas: Technical Optimization, what AI crawlers can actually read once JavaScript is stripped away; Content Quality, how answerable, factual, and quotable the writing is; and AI Presence, where it tests your content against live answer engines and records whether your domain is cited, mentioned, or passed over for a competitor. This is content tracking, not prompt tracking. GEO IQ reads your page and tests the prompts that content already answers, rather than a list you hand it, then returns recommendations ranked by score improvement. -
