ChatGPT, Le chat and other AI chats have a very annoying habit of using old coding practices and skipping the part where you get the actually AI-generated content back. Instead, it often returns the whole JSON array with 10+ quite meaningless details.
Step 1
To obtain a Mistral API key, follow these steps:
Step 2 - code
Step 3:
The Mistral API focuses on performance and accessibility, offering lightweight and efficient models designed to deliver high-quality results in a wide range of use cases.
Step 1
To obtain a Mistral API key, follow these steps:
- Create an Account: Visit Mistral AI's website and sign up for an account.
- Set Up Billing Information: After logging in, navigate to the Billing section and provide the necessary payment details to activate your account.
- Generate API Key:
- Go to the API Keys page.
- Click on "Create new key".
- Optionally, assign a name and set an expiration date for the key.
- Click "Create key".
- Secure Your API Key: Once generated, copy the API key immediately, as it will not be displayed again for security reasons. Store it securely and avoid sharing it with others.
Step 2 - code
PHP:
$mistralKey = "you api key get one from https://console.mistral.ai/";
// API endpoint ex mistral-small-latest - mistral-large-latest
function mistralApiRequest($model, $temperature, $systemPrompt, $message) {
global $mistralKey;
// Define the API endpoint
$apiUrl = 'https://api.mistral.ai/v1/chat/completions'; // Replace with the actual Mistral API endpoint
// Prepare the request data
$data = [
'model' => $model,
'temperature' => $temperature,
'messages' => [
[
'role' => 'system',
'content' => $systemPrompt
],
[
'role' => 'user',
'content' => $message
]
],
'safe_prompt' => false,
'stream' => false,
'presence_penalty' => 0,
'frequency_penalty' => 0,
'top_p' => 1
];
// Initialize cURL session
$ch = curl_init($apiUrl);
// Set cURL options
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-Type: application/json',
'Authorization: Bearer ' . $mistralKey
]);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
// Execute the request
$response = curl_exec($ch);
// Check for cURL errors
if (curl_errno($ch)) {
$error_msg = curl_error($ch);
curl_close($ch);
throw new Exception('cURL error: ' . $error_msg);
}
// Close the cURL session
curl_close($ch);
// Decode the JSON response
$responseData = json_decode($response, true);
// Check for API errors
if (isset($responseData['error'])) {
// mail("you email", "Mistral API Error", "EXIT. \n\nSystem promt: $systemPrompt. \n\n Mistral API Error: " . $responseData['error']);
throw new Exception('API error: ' . $responseData['error']);
}
// Extract and return AI text
if (isset($responseData['choices']) && !empty($responseData['choices'])) {
$firstChoice = $responseData['choices'][0];
if (isset($firstChoice['message']['content'])) {
return $firstChoice['message']['content'];
} else {
throw new Exception('No content found in the first choice.');
}
} else {
print_r($responseData);
// mail("you email", "Mistral response Error, "EXIT. \n\nSystem promt: $systemPrompt. \n\n Mistral response Error: " . $response);
throw new Exception('No responses found in the API response.');
}
} // end mistralApiRequestStep 3:
PHP:
<?php
// Define the parameters for the API request
$model = "mistral-large-latest"; // Replace with the desired model
$temperature = 0.7; // Adjust the temperature as needed
$systemPrompt = "You are a helpful assistant.";
$userMessage = "What is the capital of France?";
try {
// Call the function
$response = mistralApiRequest($model, $temperature, $systemPrompt, $userMessage);
// Output the response
echo "AI Response: " . $response;
} catch (Exception $e) {
// Handle any exceptions
echo "Error: " . $e->getMessage();
}
?>What is the Mistral API?
