Inference for Machine‑Native Intelligence.

Decision models classify, label, rerank and approve in milliseconds, for a fraction of a cent. The open question is whether you can trust their calls.

See how they score on public benchmarks, with speed and cost side by side, in the Decision Leaderboard. Then make the calls yourself in the Decision Arena and find the model that decides like you.

//Use Cases

What Decision Models Are For.

Reach for a decision model when the same question comes up again and again, for every ticket, document, transaction, or search result, and the answer is a pick from a set, a score, or a yes/no. These four jobs cover most of it.

Classification

Sort inputs by intent, category, or meaning, without relying on rigid rules.

Use it when each input belongs in exactly one bucket, like routing a ticket to the right team.

  • Intent classification
  • Ticket categorization
  • Document classification
  • Message triage

Labeling

Apply consistent labels to text and other supported content, at the volume your data arrives.

Use it when an input can carry several tags at once, like tagging content for search or analytics.

  • Content labeling
  • Semantic tagging
  • Metadata generation
  • Annotation workflows

Evaluation

Judge inputs against your criteria and policies, and get back a verdict you can act on automatically.

Use it when you need a pass/fail or a score against your own rules, like flagging transactions for review.

  • Policy evaluation
  • Content moderation
  • Risk assessment
  • Model output grading

Reranking

Order candidates by relevance to a query, so the best results reach your users and your agents first.

Use it when you already have candidates and need the best ones first, like search results or documents for an agent.

  • Search reranking
  • RAG retrieval
  • Recommendation ranking
  • Candidate filtering

//Decision Models

Every Decision Model, One API.

Models that read a state and return a choice, a score, or a yes/no, instead of text. Call any of them through the same API.

//Customization

From Zero-Shot to Your Standards.

Start with pretrained models and natural-language instructions.

When your requirements become more specific, adapt supported models with domain examples, labeled decisions, and feedback.

Post-training makes it possible to improve task-specific performance without building a foundation model from scratch.

Recurrence post-trains models for specific verticals and decision types, so they start closer to how your industry already decides.

Post-trained for your vertical

  • Finance
  • Trust & Safety
  • Legal
  • Customer Operations
  • Media
  1. Start Zero-Shot

    Select an available model and describe the task.

  2. Evaluate

    Test the model against examples relevant to your domain.

  3. Specialize

    Use supported post-training workflows to improve model behavior.

  4. Deploy

    Run your specialized model on Recurrence or in your own environment.

//Deployment

Run It Where Your Data Lives.

Every model on Recurrence, including the ones you post-train, runs two ways: hosted by us, or inside your own infrastructure.

Same models, same API. You choose where they run.

Managed

On Recurrence

Send requests to Recurrence and get decisions back.

  • No serving infrastructure to run or scale
  • Start with an API key
  • Good for getting started and spiky workloads

Self-hosted

In your environment

Deploy the same models in your own cloud account or data center.

  • Requests and data stay inside your network
  • Runs next to the pipelines and agents that call it
  • Fits teams with data residency or security reviews

Same API

One request format on Recurrence or in your environment. Moving is a config change.

Your models travel

Models you post-train can run either way, not just the stock ones.

Mix per workload

Keep sensitive workloads in-house and send the rest to Recurrence.

Put Intelligence Behind Every Decision.

Access leading decision models, customize them for your domain, and run them wherever your data lives.
