# Component Parameters

Override a Pop component parameters for one source

A Pop component can be given parameters when the Pop is defined — a VLM's prompt, a confidence threshold. Component parameters override those **for one source**, so a single session can ask a different question of every image without redefining the Pop.

Give the component an `id` in the Pop, then reference that id when you submit the source.

```python
from eyepop.worker.worker_types import ComponentParams, InferenceComponent, Pop

pop = Pop(components=[
    InferenceComponent(id=1, ability="eyepop.image-contents:latest"),
])

with EyePopSdk.sync_worker(pop=pop) as endpoint:
    result = endpoint.upload(
        "photo.jpg",
        params=[ComponentParams(componentId=1, values={
            "prompts": [{"prompt": "How many people are wearing hard hats?"}],
        })],
    ).predict()
```

```typescript
import { EyePop, PopComponentType } from '@eyepop.ai/eyepop'

const endpoint = await EyePop.workerEndpoint({
    pop: {
        components: [
            { type: PopComponentType.INFERENCE, id: 1, ability: 'eyepop.image-contents:latest' },
        ],
    },
}).connect()

const results = await endpoint.process({
    source: { path: 'photo.jpg' },
    componentParams: [
        {
            componentId: 1,
            values: { prompts: [{ prompt: 'How many people are wearing hard hats?' }] },
        },
    ],
})

Which values a component accepts depends on its ability — see [Abilities](/developer-documentation/platform/abilities.md) and [Components](/developer-documentation/platform/pop/pop-components.md).
