## PromptKit Profiles

The optional **promptkit** object selects one source of profile definitions:
|
||||
The optional **promptkit** object selects one source of profile definitions and
|
||||
may register one conventional local OpenAI-compatible backend:
|
||||
|
||||
~~~yaml
|
||||
version: 4
|
||||
|
||||
promptkit:
|
||||
profile_dir: /path/to/profiles
|
||||
# profile_file: /path/to/profiles.yml
|
||||
profile_dir: ./profiles
|
||||
# profile_file: ./profiles.yml
|
||||
local_backend:
|
||||
endpoint: http://localhost:8000/v1
|
||||
concurrency_limit: 2
|
||||
~~~
|
||||
|
||||
| Field | Type | Rules |
|
||||
| --- | --- | --- |
|
||||
| **profile_dir** | string | Non-empty directory containing profile files. |
|
||||
| **profile_file** | string | Non-empty profile file. |
|
||||
| **local_backend** | object | Optional registration for the conventional PromptKit backend ID **local**. |
|
||||
| **local_backend.endpoint** | string | Required when **local_backend** is present; absolute HTTP or HTTPS URL with a host. |
|
||||
| **local_backend.concurrency_limit** | integer | Optional non-negative limit; defaults to 0. |
|
||||
|
||||
Set at most one of these fields. Profile IDs used by a binding must be available
|
||||
from the selected PromptKit profile source when the pipeline is resolved.
|
||||
Keep credentials out of this file: configure a profile to read its credential
|
||||
from an environment variable, then set that environment variable only in the
|
||||
run environment. PromptKit owns the profile-file format; see the
|
||||
[PromptKit upstream boundary](integrations/pkg-promptkit.md) for the pinned
|
||||
package and canonical format reference.
|
||||
The optional local registration may coexist with either profile source or with
|
||||
PromptKit's built-in profiles.
|
||||
|
||||
When **local_backend** is present, its endpoint is trimmed and must use HTTP or
|
||||
HTTPS case-insensitively, be absolute, and have a non-empty host. URL paths are
|
||||
allowed. User information, queries, and fragments are rejected. A zero
|
||||
**concurrency_limit** leaves the local backend unrestricted inside PromptKit;
|
||||
a positive value limits simultaneous local generations. The application-wide
|
||||
**concurrency.total_llm** limit still applies in both cases. Neither local
|
||||
backend field has an environment override. Omitting **local_backend** registers
|
||||
nothing and preserves existing built-in and endpoint-only profile behavior.
|
||||
|
||||
A file-backed PromptKit profile selects the registration by its case-sensitive
|
||||
backend ID:
|
||||
|
||||
~~~yaml
|
||||
id: local-summary
|
||||
backend: local
|
||||
model: example-model
|
||||
~~~
|
||||
|
||||
Keep credentials out of the local-backend object. A PromptKit profile may name
|
||||
its credential environment variable through `api_key_env`; set that variable
|
||||
only in the run environment. PromptKit owns the
|
||||
[pinned profile-file format](https://gitea.maximumdirect.net/eric/promptkit/src/tag/v0.3.0/docs/formats.md).
|
||||
The [PromptKit upstream boundary](integrations/pkg-promptkit.md) identifies the
|
||||
supported package API, and [Operations](operations.md#operational-limits)
|
||||
describes the effective concurrency layers.
