In this notebook, you'll learn how to get started with the PaLM API tuning service using curl commands or the Python request API to call the PaLM REST API. Here, you'll learn how to tune the text model behind the PaLM API's text generation service.
Setup
Authenticate
The PaLM API lets you tune models on your own data. Since it's your data and your tuned models this needs stricter access controls than API-Keys can provide.
Before you can run this tutorial, you'll need to setup OAuth for your project.
If you want to run this notebook in Colab start by uploading your
client_secret*.json file using the "File > Upload" option.
cp client_secret*.json client_secret.jsonls
client_secret.json
This gcloud command turns the client_secret.json file into credentials that can be used to authenticate with the service.
import os
if 'COLAB_RELEASE_TAG' in os.environ:
# Use `--no-browser` in colab
!gcloud auth application-default login --no-browser --client-id-file client_secret.json --scopes='https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/generative-language.tuning'
else:
!gcloud auth application-default login --client-id-file client_secret.json --scopes='https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/generative-language.tuning'
Calling the REST API with CURL
This section gives example curl statements to call the REST API. You will learn how to create a tuning job, check its status and once complete, make an inference call.
Set variables
Set variables for recurring values to use for the rest of the REST API calls. The code is using the Python os library to set environment variables which is accessible in all the code cells.
This is specific to the Colab notebook environment. The code in the next code cell is equivalent to running the following commands in a bash terminal.
export access_token=$(gcloud auth application-default print-access-token)
export project_id=my-project-id
export base_url=https://generativelanguage.googleapis.com
import os
access_token = !gcloud auth application-default print-access-token
access_token = '\n'.join(access_token)
os.environ['access_token'] = access_token
os.environ['project_id'] = "project-id"
os.environ['base_url'] = "https://generativelanguage.googleapis.com"
List tuned models
Verify your authentication setup by listing the currently available tuned models.
curl -X GET ${base_url}/v1beta3/tunedModels \-H 'Content-Type: application/json' \-H "Authorization: Bearer ${access_token}" \-H "x-goog-user-project: ${project_id}" | grep name

Create tuned model
To create a tuned model, you need to pass your dataset to the model in the training_data field.
For this example, you will tune a model to generate the next number in the sequence. For example, if the input is 1, the model should output 2. If the input is one hundred, the output should be one hundred one.
curl -X POST ${base_url}/v1beta3/tunedModels \-H 'Content-Type: application/json' \-H "Authorization: Bearer ${access_token}" \-H "x-goog-user-project: ${project_id}" \-d '{"display_name": "number generator model","base_model": "models/text-bison-001","tuning_task": {"hyperparameters": {"batch_size": 2,"learning_rate": 0.001,"epoch_count":3,},"training_data": {"examples": {"examples": [{"text_input": "1","output": "2",},{"text_input": "3","output": "4",},{"text_input": "-3","output": "-2",},{"text_input": "twenty two","output": "twenty three",},{"text_input": "two hundred","output": "two hundred one",},{"text_input": "ninety nine","output": "one hundred",},{"text_input": "8","output": "9",},{"text_input": "-98","output": "-97",},{"text_input": "1,000","output": "1,001",},{"text_input": "10,100,000","output": "10,100,001",},{"text_input": "thirteen","output": "fourteen",},{"text_input": "eighty","output": "eighty one",},{"text_input": "one","output": "two",},{"text_input": "three","output": "four",},{"text_input": "seven","output": "eight",}]}}}}' | tee tunemodel.json

Get tuned model state
The state of the model is set to CREATING during training and will change to ACTIVE once its complete.
Below is a bit of python code to parse out the generated model name from the response JSON. If you're running this in a terminal you can try using a bash JSON parser to parse the response.
import json
first_page = json.load(open('tunemodel.json'))
os.environ['modelname'] = first_page['metadata']['tunedModel']
print(os.environ['modelname'])
tunedModels/number-generator-model-q2d0uism5ivd
Do another GET request with the model name to get the model metadata which includes the state field.
curl -X GET ${base_url}/v1beta3/${modelname} \-H 'Content-Type: application/json' \-H "Authorization: Bearer ${access_token}" \-H "x-goog-user-project: ${project_id}" \ | grep state

Once your tuning job is finished, you can use it to generate text with the text service.
curl -X POST ${base_url}/v1beta3/${modelname}:generateText \-H 'Content-Type: application/json' \-H "Authorization: Bearer ${access_token}" \-H "x-goog-user-project: ${project_id}" \-d '{"prompt": {"text": "4"},"temperature": 1.0,"candidate_count": 2}' | grep output

The output from your model may or may not be correct. If the tuned model isn't performing up to your required standards, you can try adding more high quality examples, tweaking the hyperparameters or adding a preamble to your examples. You can even create another tuned model based on the first one you created.
See the tuning guide for more guidance on improving performance.
Call the REST API with Python requests
You can call the rest API with any library that allows you to send http requests. The next set of examples use the Python requests library, and demonstrates some of the more advanced features.

Create tuned model
Same as for the Curl example, you pass in the dataset through the training_data field.
operation = requests.post(
url = f'{base_url}/v1beta3/tunedModels',
headers=headers,
json= {
"display_name": "number generator",
"base_model": "models/text-bison-001",
"tuning_task": {
"hyperparameters": {
"batch_size": 4,
"learning_rate": 0.001,
"epoch_count":3,
},
"training_data": {
"examples": {
"examples": [
{
'text_input': '1',
'output': '2',
},{
'text_input': '3',
'output': '4',
},{
'text_input': '-3',
'output': '-2',
},{
'text_input': 'twenty two',
'output': 'twenty three',

'output': 'two hundred one',

Set a variable with the name of your tuned model to use for the rest of the calls.

Get tuned model state
You can check the progress of your tuning job by checking the state field. CREATING means the tuning job is still ongoing and ACTIVE means the trainins is complete and the tuned model is ready to use.
tuned_model = requests.get(
url = f'{base_url}/v1beta3/{name}',
headers=headers,
)
tuned_model.json()
{'name': 'tunedModels/number-generator-ncqqnysl74dt',
'baseModel': 'models/text-bison-001',
'displayName': 'number generator',
'state': 'CREATING',
'createTime': '2023-09-19T19:56:25.999303Z',
'updateTime': '2023-09-19T19:56:25.999303Z',
'tuningTask': {'startTime': '2023-09-19T19:56:26.297862545Z',
'hyperparameters': {'epochCount': 3, 'batchSize': 4, 'learningRate': 0.001} },
'temperature': 0.7,
'topP': 0.95,
'topK': 40}
The code below checks the state field every 5 seconds until it is no longer in the CREATING state.

error = op_json.get('error')
percent = op_json['metadata'].get('completedPercent')
if percent is not None:

print()

Run inference
Once the tuning job is finished, you can use it to generate text in the same way you would use the base text model.
import time
m = requests.post(
url = f'{base_url}/v1beta3/{name}:generateText',
headers=headers,
json= {
"prompt": {
"text": "9"
},
})
import pprint
print(m.json()['candidates'][0]['output'])
9
The output from your model may or may not be correct. If the tuned model isn't performing up to your required standards, you can try adding more high quality examples, tweaking the hyperparameters or adding a preamble to your examples.
