# BGE Large EN v1.5

> 1024-dimension English embeddings, and still one of the most widely benchmarked retrieval models in production. The 512-token window forces chunking, which is why the newer entries above exist — but an index already built on it stays comparable.

## Overview

1024-dimension English embeddings, and still one of the most widely benchmarked retrieval models in production. The 512-token window forces chunking, which is why the newer entries above exist — but an index already built on it stays comparable.

## Specs

| Field | Value |
| - | - |
| Model ID | `bge-large-en` |
| Best for | English-only retrieval, existing BGE indexes |
| Context window | 512 |
| Input modalities | Text |
| Output modalities | Text |
| Speed | Fast |
| Cost band | Cheap |
| Release stage | Stable |

## Pricing

| | Per 1M tokens |
| - | :-: |
| Input | \$0.0135 |
| Output | \$0.00 |

## Example

```python theme={null}
from openai import OpenAI

client = OpenAI(base_url="https://kymaapi.com/v1", api_key="kyma-...")

response = client.embeddings.create(
    model="bge-large-en",
    input=["first document", "second document"],
)
```

## Agent query example

Ask the API which models fit, instead of hardcoding an id:

```bash theme={null}
curl "https://kymaapi.com/v1/models?recommended_for=search-documents&quality_tier=strong"
```
