    Choosing the model

    Every week there's a new model, and you need one decision that holds.

    We test candidate models on your own examples and pick the best fit on quality, latency and cost, then keep the choice on the server so switching later is a config change.

    • Tested on your data, not benchmarks
    • Quality, speed and cost compared
    • Swappable without an app release

    Running costs, before you build

    You need to know what this costs per user before you promise it to anyone.

    We estimate LLM running costs from real token counts before building, then cap them in production with per-user quotas.

    • Cost estimate per user and per feature
    • Quotas and limits in production
    • Caching where it's safe
    Crumb Count. Per-user quotas and server-owned model choice.

    Answers from your documents and data

    The model sounds confident and is wrong about your business.

    Retrieval over your own documents and data so answers come from what you actually know, with limits on what the model is allowed to read.

    • Search over your own content
    • Answers that cite where they came from
    • Access rules enforced outside the model

    LLM security review

    Your AI feature can read data and call tools. Who checked what an attacker can make it do?

    An LLM security review for startups: prompt injection, tool-call permissions, write access to your database, and cost attacks, with a written report and tests you keep.

    • Prompt injection audit
    • Tool and database permissions
    • Cost and abuse attacks
    • Written findings and tests you keep
    Crumb Count. A 1,299-line adversarial suite shipped with the app.

Questions, answered.

Do you build on OpenAI only?

We default to OpenAI's models and compare others for your case before deciding.

Can you review an LLM feature another team built?

Yes. A security review covers prompt injection, tool permissions and cost attacks, and ends with written findings.

How do you estimate LLM costs?

From real token counts on your own examples, per user and per feature, before anything is built.
