Informazioni su come usare la modalità JSON

import os
from openai import AzureOpenAI

client = AzureOpenAI(
  azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT"), 
  api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
  api_version="2024-03-01-preview"
)

response = client.chat.completions.create(
  model="YOUR-MODEL_DEPLOYMENT_NAME", # Model = should match the deployment name you chose for your model deployment
  response_format={ "type": "json_object" },
  messages=[
    {"role": "system", "content": "You are a helpful assistant designed to output JSON."},
    {"role": "user", "content": "Who won the world series in 2020?"}
  ]
)
print(response.choices[0].message.content)

Output

{
  "winner": "Los Angeles Dodgers",
  "event": "World Series",
  "year": 2020
}

In questo esempio, l'utente richiede informazioni cronologiche in uno schema JSON specifico perché prevede di usare l'output per ulteriori script.

$openai = @{
   api_key     = $Env:AZURE_OPENAI_API_KEY
   api_base    = $Env:AZURE_OPENAI_ENDPOINT # like the following https://YOUR_RESOURCE_NAME.openai.azure.com/
   api_version = '2024-03-01-preview' # may change in the future
   name        = 'YOUR-DEPLOYMENT-NAME-HERE' # name you chose for your deployment
}

$headers = @{
  'api-key' = $openai.api_key
}

$messages  = @()
$messages += @{
  role     = 'system'
  content  = 'You are a helpful assistant designed to output JSON.'
}
$messages += @{
  role     = 'user'
  content  = 'Who threw the final pitch during the world series each year from 1979 to 1989?'
}
$messages += @{
  role     = 'user'
  content  = 'Respond using schema. response:{year, team, player, player_height}.'
}

$body      = @{
  response_format = @{type = 'json_object'}
  messages = $messages
} | ConvertTo-Json

$url = "$($openai.api_base)/openai/deployments/$($openai.name)/chat/completions?api-version=$($openai.api_version)"

$response = Invoke-RestMethod -Uri $url -Headers $headers -Body $body -Method Post -ContentType 'application/json'
$response.choices[0].message.content

Output

La funzionalità di output JSON semplifica la conversione della risposta in un oggetto .NET da parte di PowerShell. Passare i dati tramite una pipe | per eseguire più passaggi di scripting, ad esempio l'ordinamento.

if ($response.choices[0].finish_reason -eq 'stop') {
  $response.choices[0].message.content | ConvertFrom-Json | ForEach-Object response | Sort player_height -Descending
} else { write-warning 'the JSON response was incomplete'}
