AI Stack

Build the right AI stack for every T&S problem.

Move faster with the models, agents, evals, and workflows you need to defend your platform.

Models

Reach for the right model, from fast to frontier.

Choose the right model for the job, from fast classifiers to frontier LLMs, and keep the flexibility to change your mind as the work evolves. Swap models without rebuilding the whole flow, then test each setup against your own evals and benchmarks before it goes live.

PolicyLM-1.7B

A 1.7B open-weights model for real-time classification, developed by Musubi. Cheap enough to run on 100% of your traffic, it scores the good stuff as readily as the harmful.

Frontier and open LLMs

The newest frontier and open safety models, added as they ship. They come matched to your use case and optimized for speed, reasoning, or safety.

Adaptive classifiers

Custom behavioral models for adversarial fraud that train on full profile data, content, and behavior. They return a risk score and the signals behind it, and retrain daily on your moderators' decisions.

Moderation Agents

Custom moderation agents.

Point a moderation agent at your queue and it works each case across steps, clearing the straightforward ones and handing your team the tough ones with a full reasoning trace.

In early deployments, automating the investigative legwork has cut manual review by around 60%, so your analysts can dig in on the cases that really get their brains going.

Evaluation

Ship AI that holds up under real conditions.

Model Benchmarking

Compare frontier LLMs and fine-tuned safety models against your own labeled data. Check for bias, coverage gaps, and regressions before they touch production.

Evaluation sets

Build evaluation sets that surface edge cases and gaps. Stratify by category, severity, or any field your team cares about.

Policy and prompt testing

A/B test different policy versions and prompts to see which has higher accuracy, precision, recall, or F1 scores. Revert to past versions any time you need to.

Benchmarking results comparing a model against a previous version, showing agreement, percent changed, macro F1, and net correct.

Workflows

Custom workflows and decision trees.

Chain classifiers, LLMs, adaptive fraud models, and human review into one workflow that matches how your team makes decisions. Straightforward cases can resolve automatically, ambiguous ones escalate to a larger model, and high-stakes calls go to a person.

Build the flow with drag-and-drop controls, then reshape it any time without waiting on engineering.
