  # Try out in the Hosted inference API
  
  In the right panel, you can try to the model (although it only handles a short sequence length).
  Enter the document you want to summarize in the panel on the right.
  
  # Model Loading
  The model (based on a GPT2 base architecture) can be loaded in the following way:
  ```
  from transformers import GPT2LMHeadModel, GPT2TokenizerFast
  
  model = GPT2LMHeadModel.from_pretrained("philippelaban/summary_loop10")
  tokenizer = GPT2TokenizerFast.from_pretrained("philippelaban/summary_loop10")
  ```
  
  # Example Use
  ```
  document = "Bouncing Boulders Point to Quakes on Mars. A preponderance of boulder tracks on the red planet may be evidence of recent seismic activity. If a rock falls on Mars, and no one is there to see it, does it leave a trace? Yes, and it's a beautiful herringbone-like pattern, new research reveals. Scientists have now spotted thousands of tracks on the red planet created by tumbling boulders. Delicate chevron-shaped piles of Martian dust and sand frame the tracks, the team showed, and most fade over the course of a few years. Rockfalls have been spotted elsewhere in the solar system, including on the moon and even a comet. But a big open question is the timing of these processes on other worlds — are they ongoing or did they predominantly occur in the past?"
  
  tokenized_document = tokenizer([document], max_length=300, truncation=True, return_tensors="pt")["input_ids"].cuda()
  input_shape = tokenized_document.shape
  outputs = model.generate(tokenized_document, do_sample=False, max_length=500, num_beams=4, num_return_sequences=4, no_repeat_ngram_size=6, return_dict_in_generate=True, output_scores=True)
  candidate_sequences = outputs.sequences[:, input_shape[1]:] # Remove the encoded text, keep only the summary
  candidate_scores = outputs.sequences_scores.tolist()
  
  for candidate_tokens, score in zip(candidate_sequences, candidate_scores):
      summary = tokenizer.decode(candidate_tokens)
      print("[Score: %.3f] %s" % (score, summary[:summary.index("END")]))
  ```
  
  # Example output
  ```
  [Score: -0.084]  Here's what you need to know about rockfalls
  [Score: -0.087]  Here's what you need to know about these tracks
  [Score: -0.091]  Here's what we know so far about these tracks
  [Score: -0.101]  Here's what you need to know about rockfall
