# Update Specification

## Specification: Update Specification

### User Intent

"I want to update a model specification's configuration"

### Operation

* **SDK Method**: `graphlit.updateSpecification()`
* **GraphQL**: `updateSpecification` mutation
* **Entity Type**: Specification
* **Common Use Cases**: Adjust model parameters, change temperature, update token limits

### TypeScript (Canonical)

```typescript
import { Graphlit } from 'graphlit-client';
import { Types } from 'graphlit-client/dist/generated/graphql-types';

const graphlit = new Graphlit();

const specId = 'spec-id-here';

// Update temperature and token limit
await graphlit.updateSpecification({
  id: specId,
  openAI: {
    temperature: 0.2,  // More deterministic
    completionTokenLimit: 2000
  }
});

console.log('Specification updated');
```

## Update specification (snake\_case)

await graphlit.updateSpecification( specification=SpecificationUpdateInput( id=spec\_id, open\_ai=OpenAiModelPropertiesInput( temperature=0.2, completion\_token\_limit=2000 ) ) )

````

**C#**:
```csharp
using Graphlit;

var client = new Graphlit();

var specId = "spec-id-here";

// Update specification (PascalCase)
await graphlit.UpdateSpecification(new SpecificationUpdateInput {
    Id = specId,
    OpenAI = new OpenAIModelPropertiesInput {
        Temperature = 0.2f,
        CompletionTokenLimit = 2000
    }
});
````

### Parameters

#### SpecificationUpdateInput (Required)

* **`id`** (string): Specification ID
* Provider-specific updates:
  * **`openAI`**: Update OpenAI configuration
  * **`anthropic`**: Update Claude configuration
  * **`google`**: Update Gemini configuration

### Response

```typescript
{
  updateSpecification: {
    id: string;
  }
}
```

### Variations

#### 1. Update Temperature

```typescript
await graphlit.updateSpecification({
  id: specId,
  openAI: {
    temperature: 0.1  // More focused
  }
});
```

#### 2. Update Token Limit

```typescript
await graphlit.updateSpecification({
  id: specId,
  openAI: {
    completionTokenLimit: 4000  // Longer responses
  }
});
```
