Refused: a name taken by another capability or by a published job's output (409 name\_taken), corrections of two questions or not captured (400), and a question another of the org's capabilities answers (409 route\_conflict). ## Request 2 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ------------- | ---- | --------- | -------- | ----------------------------------------------------------------------------------------------------------------- | | `corrections` | body | string\[] | — | Corrections are the corrections it is taught from: captured corrections of one question, which becomes its route. | | `name` | body | string | — | Name is its name: lowercase words joined by hyphens, at most 64. | ## Response | Status | Body | Meaning | | --------- | ---------------- | ------- | | `201` | train.Capability | created | | `default` | problem-details | refused | `201` body — 35 fields. | Field | In | Type | Always | Description | | --------------------------- | ---- | ---------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `by` | body | string | — | | | `corrections` | body | string\[] | — | Corrections are the corrections it is taught from. | | `created` | body | integer (int64) | — | | | `installed` | body | integer (int64) | — | Installed is the version in the org's published set, 0 when none. | | `live` | body | train.Live | — | | | `live.damage` | body | integer (int64) | — | | | `live.damage_rate` | body | number (double) | — | | | `live.fires` | body | integer (int64) | — | Fires counts decisions it answered otherwise than the base would have. | | `live.last_fired` | body | integer (int64) | — | LastFired is when it last fired, unix seconds; 0 never. | | `live.neutral` | body | integer (int64) | — | | | `live.repair_rate` | body | number (double) | — | | | `live.repairs` | body | integer (int64) | — | Repairs are fires that changed the label and no correction contradicts; Damage, fires whose label a correction put back to the base's; Neutral, fires that kept the base's label. | | `live.version` | body | integer (int64) | — | | | `name` | body | string | — | Name is its name, one per org; it is the name its versions install under. | | `question` | body | train.Question | — | | | `question.key` | body | string | — | | | `question.labels` | body | string\[] | — | | | `question.type` | body | string | — | | | `state` | body | string | — | State is where it is in its life: draft, trained, evaluated, publishable, installed, active, disabled or needs\_validation. | | `updated` | body | integer (int64) | — | | | `version` | body | integer (int64) | — | Version is its latest version, 0 in draft. | | `versions` | body | train.Version\[] | — | Versions are its versions, newest first (one capability read). | | `versions[].at` | body | integer (int64) | — | | | `versions[].base_sha256` | body | string | — | BaseSHA256 is Kai's weights it was taught over. | | `versions[].by` | body | string | — | | | `versions[].bytes` | body | integer (int64) | — | Bytes is its artifact's size. | | `versions[].corrections` | body | string\[] | — | Corrections are the corrections it was taught from. | | `versions[].evaluation` | body | any | — | Evaluation is its evaluation record, in the shared /evals words. | | `versions[].form` | body | string | — | Form is calibration, head or pair; Rank its place, 1 the smallest. | | `versions[].passed` | body | boolean | — | Passed says its evaluation passed the gate: it is publishable. | | `versions[].questions` | body | string\[] | — | Questions are the question keys it answers. | | `versions[].rank` | body | integer (int64) | — | | | `versions[].representation` | body | string | — | Representation is what it reads of Kai (the weights, tokenizer, layout and pooling, hashed): the only Kai it serves on, whatever the release. | | `versions[].sha256` | body | string | — | SHA256 is its artifact's: the tar the decision service installs. | | `versions[].version` | body | integer (int64) | — | | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo capabilities create ``` **SDK** **.ts** ```ts import { Configuration, TrainApi } from 'hanzoai';
