Build it yourself or use it ready-made?
There are plenty of open models and tools. Turning them into a platform for your team is the real work. kayetana has already done it.

What you'd have to build yourself.
| kayetana | DIY stack | |
|---|---|---|
| Running models | Via Ollama, already set up | Possible, set it up yourself |
| Team interface | Playground with roles | Pick one and connect it |
| Answers with per-sentence sources | ✓ | Build it yourself |
| Embed, rerank, classify, audio | One API under /v2 | Several services, several APIs |
| API keys with monthly limits | ✓ | Build it yourself |
| Usage per day, key and model | ✓ | Build it yourself |
| HTTPS, backups, restarts | Set up | Set it up yourself |
| Free choice of every piece | Within the platform | ✓ |
| Cost | Flat fee for the platform | No license, but your own time |
Building it yourself gives you full freedom. In return, you handle setup, upkeep and updates for every piece.
One platform instead of many parts.
Chat, answers from documents, embed, rerank, classify, tokens, audio, datasets and fine-tuning all run in one interface and through one API. Your team signs in once and finds everything.
- Owner, Admin and Member roles
- Invite by link or single sign-on (OIDC, SAML)
- Sample code in Python, TypeScript and curl

Frequently asked questions
Does kayetana use open-source pieces itself?
Yes. Models run via Ollama, and every bundled model is openly licensed (Apache 2.0 or MIT). kayetana ties them together into a platform with a UI, an API and admin tools.
Can I bring my own models?
Yes. You load new models by name from the Ollama library and set a default model for each task. With fine-tuning, you can also train your own variants.
What would I need to think about when building it myself?
Besides the models, you'd need a UI, users and roles, API keys with limits, citations, usage tracking, HTTPS and backups. And you'd have to maintain and update every part.
Can I build kayetana into my own tools through the API?
Yes. The REST API under /v2 covers chat, embed, rerank, classify, tokens, transcription, datasets and fine-tuning. You can build your own tools on top of it.
