Resolution overview

Within the following sections, we stroll by the steps to fine-tune the Cohere Command R mannequin on SageMaker. This contains getting ready the information, deploying a mannequin, getting ready for fine-tuning, creating an endpoint for inference, and performing inference.

Put together the fine-tuning knowledge

Earlier than you can begin a fine-tuning job, you’ll want to add a dataset with coaching and (optionally) analysis knowledge.

First, be sure that your knowledge is in jsonl format. It ought to have the next construction:

•  messages – This comprises an inventory of messages of the dialog. A message consists of the next elements:
•  function – This specifies the present speaker. You’ll be able to choose from System, Consumer, or Chatbot.
•  content material – This comprises the content material of the message.

The next is an instance that trains a chatbot to reply questions. For the sake of readability, the doc spans over a number of traces. In your dataset, be sure that every line comprises one complete instance.

{
  "messages": [
    {
      "role": "System",
      "content": "You are a large language model trained by Cohere."
    },
    {
      "role": "User",
      "content": "Hi! What were Time magazines top 10 cover stories in the last 10 years?"
    },
    {
      "role": "Chatbot",
      "content": "Time magazines top 10 cover stories in the last 10 years were:nn1. Volodymyr Zelenskyyn2. Elon Muskn3. Martin Luther King Jr.n4. How Earth Survivedn5. Her Lasting Impactn6. Nothing to See Heren7. Meltdownn8. Deal With Itn9. The Top of American10. Bitter Pill"
    },
    {
      "role": "User",
      "content": "Who is Volodymyr Zelenskyy?"
    },
    {
      "role": "Chatbot",
      "content": "Volodymyr Zelenskyy is a Ukrainian politician who was elected President of Ukraine in 2019. He previously served as the Minister of Internal Affairs in the government of Prime Minister Volodymyr Groysman."
    },
    {
      "role": "User",
      "content": "Thank you!"
    }
  ]
}

Deploy a mannequin

Full the next steps to deploy the mannequin:

1. On AWS Marketplace, subscribe to the Cohere Command R mannequin

After you subscribe to the mannequin, you’ll be able to configure it and create a coaching job.

2. Select View in Amazon SageMaker.

Alternatively, you need to use the next example notebook to create the coaching job.

Put together for fine-tuning

To fine-tune the mannequin, you want the next:

• Product ARN – This can be offered to you after you subscribe to the product.
• Coaching dataset and analysis dataset – Put together your datasets for fine-tuning.
• Amazon S3 location – Specify the Amazon Easy Storage Service (Amazon S3) location that shops the coaching and analysis datasets.
• Hyperparameters – Effective-tuning sometimes entails adjusting numerous hyperparameters like studying charge, batch dimension, variety of epochs, and so forth. You should specify the suitable hyperparameter ranges or values to your fine-tuning process.

Create an endpoint for inference

When the fine-tuning is full, you’ll be able to create an endpoint for inference with the fine-tuned mannequin. To create the endpoint, use the create_endpoint technique. If the endpoint already exists, you’ll be able to hook up with it utilizing the connect_to_endpoint technique.

Carry out inference

Now you can carry out real-time inference utilizing the endpoint. The next is the pattern message that you simply use for enter:

message = "Classify the next textual content as both very detrimental, detrimental, impartial, constructive or very constructive: mr. deeds is , as comedy goes , very foolish -- and in one of the best ways."
outcome = co.chat(message=message)
print(outcome)

The next screenshot exhibits the output of the fine-tuned mannequin.

Optionally, you may also check the accuracy of the mannequin utilizing the analysis knowledge (sample_finetune_scienceQA_eval.jsonl).

Clear up

After you have got accomplished operating the pocket book and experimenting with the Cohere Command R fine-tuned mannequin, it’s essential to scrub up the sources you have got provisioned. Failing to take action might lead to pointless prices accruing in your account. To stop this, use the next code to delete the sources and cease the billing course of:

co.delete_endpoint()
co.shut()
