A RoBERTa-base trained on ~124M tweets from January 2018 to December 2021, and finetuned for sentiment analysis with the TweetEval benchmark. This model is suitable for English.

You can use cURL or any other http client to run inferences:

```bash
curl -X POST \
    -d '{"input": "I had a wonderful day!"}'  \
    -H "Authorization: bearer $(deepctl auth token)"  \
    -H 'Content-Type: application/json'  \
    'https://api.deepinfra.com/v1/inference/cardiffnlp/twitter-roberta-base-sentiment'
```

which will give you back something similar to:

```json
{
  "results": [
    {
      "label": "POSITIVE",
      "score": 0.9998832941055298
    },
    {
      "label": "NEGATIVE",
      "score": 0.00011671594256768003
    }
  ],
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}

```


You can use our command-line tool [deepctl](/docs/getting-started) to run
inferences:

```bash
deepctl infer \
    -m 'cardiffnlp/twitter-roberta-base-sentiment'  \
    -i 'input=I had a wonderful day!'
```

which will give you back something similar to:

```json
{
  "results": [
    {
      "label": "POSITIVE",
      "score": 0.9998832941055298
    },
    {
      "label": "NEGATIVE",
      "score": 0.00011671594256768003
    }
  ],
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}

```
