What’s the significance of model-id while submitting? Can it be any string that I can use to identify my model?  
If I want to submit 2 models (with different stakes) what’s the procedure for that?

p.s. I am familiar with multi model support but don’t know how to use it.

The model\_id identifies your model to numerai. Model name is to model\_id what hostname is to IP address.

In Python, I do this:

```
import numerapi

napi = numerapi.NumerAPI(public_id=public_id, secret_key=secret_key)
napi.upload_predictions(path_to_predictions, model_id=model_id)

```

I get **public\_id** from [https://numer.ai/account](https://numer.ai/account), upon clicking the **VIEW API KEYS** button. **secret\_key** was shown once when I created my webhook. I assume you have to destroy and recreate the submit webhook to get a new secret key. (In practice I store these things in Google Cloud Secret Manager.)  
**model\_id** is the UUID for your model which is obtained from [https://numer.ai/models](https://numer.ai/models).

To manage your stake, use

```
napi.stake_increase(nmr=nmr_amount, model_id=model_id)
napi.stake_decrease(nmr=nmr_amount, model_id=model_id)

```

I don’t know how to delete a pending stake change using the API.
