| Input, per million tokens | ₦1,755 |
| Output, per million tokens | ₦4,739 |

Prices as of 8 November 2026. They are in naira and follow the exchange rate, so the [live price](https://bridge.wekoya.tech/models/step-5-preview) may differ a little. A token is roughly three quarters of a word.

## What a request costs

A request that sends 1,500 tokens (instructions, the conversation so far and a question) and gets 500 back (about 375 words) costs about ₦5.00 on 8 November 2026. A thousand of them cost about ₦5,002. When 1,000 of the input tokens are instructions that stay the same, [prompt caching](https://bridge.wekoya.tech/docs/prompt-caching) reads them at the cached rate and the request costs about ₦3.42.

## Use Step 5 Preview from your code

Bridge speaks the OpenAI format, so the OpenAI SDK works as it is: set the base URL to `https://wekoya-api.wekoya.tech/v1`, use your Bridge key, and pass `step-5-preview` as the model. [Create a key](https://bridge.wekoya.tech/sign-up), then:

```python
from openai import OpenAI

client = OpenAI(api_key="wk_live_...", base_url="https://wekoya-api.wekoya.tech/v1")
reply = client.chat.completions.create(
    model="step-5-preview",
    messages=[{"role": "user", "content": "Hello"}],
)
print(reply.choices[0].message.content)
```

Streaming works the same way, and so does [tool calling](https://bridge.wekoya.tech/docs/tools). To send a picture, add it to the message as an [image](https://bridge.wekoya.tech/docs/images). The [quickstart](https://bridge.wekoya.tech/docs) has the same in JavaScript and curl, and the [Responses API](https://bridge.wekoya.tech/docs/responses) works too.
