The Kimi intelligent assistant can upload files and answer questions based on those files. The Kimi API offers the same functionality. Below, we’ll walk through a practical example of how to upload files and ask questions using the Kimi API:
from pathlib import Path
from openai import OpenAI
client = OpenAI(
api_key="MOONSHOT_API_KEY", # Replace MOONSHOT_API_KEY with the API Key you obtained from the Kimi Open Platform
base_url="https://api.moonshot.ai/v1",
)
# 'moonshot.pdf' is an example file. We support text and image files. For image files, we provide OCR capabilities.
# To upload a file, you can use the file upload API from the openai library. Create a file object using Path from the standard library pathlib and pass it to the file parameter. Set the purpose parameter to 'file-extract'. Note that the file upload interface currently only supports 'file-extract' as a purpose value.
file_object = client.files.create(file=Path("moonshot.pdf"), purpose="file-extract")
# Get the result
# file_content = client.files.retrieve_content(file_id=file_object.id)
# Note: The retrieve_content API in some older examples is marked as deprecated in the latest version. You can use the following line instead (if you're using an older SDK version, you can continue using retrieve_content).
file_content = client.files.content(file_id=file_object.id).text
# Include the file content in the request as a system prompt
messages = [
{
"role": "system",
"content": "You are Kimi, an AI assistant provided by Moonshot AI. You excel in Chinese and English conversations. You provide users with safe, helpful, and accurate answers while rejecting any queries related to terrorism, racism, or explicit content. Moonshot AI is a proper noun and should not be translated.",
},
{
"role": "system",
"content": file_content, # <-- Here, we place the extracted file content (note that it's the content, not the file ID) in the request
},
{"role": "user", "content": "Please give a brief introduction to the content of moonshot.pdf"},
]
# Then call the chat-completion API to get Kimi's response
completion = client.chat.completions.create(
model="kimi-k2.6",
messages=messages
)
print(completion.choices[0].message)
const OpenAI = require("openai");
const fs = require("fs")
const client = new OpenAI({
apiKey: "$MOONSHOT_API_KEY",
baseURL: "https://api.moonshot.ai/v1",
});
async function main() {
// 'moonshot.pdf' is an example file. We support pdf, doc, and image formats, providing OCR capabilities for images and pdf files.
let file_object = await client.files.create({
file: fs.createReadStream("moonshot.pdf"),
purpose: "file-extract"
})
// Get the result
// file_content = client.files.retrieve_content(file_id=file_object.id)
// Note: The retrieve_content API in some older examples is marked as deprecated in the latest version. You can use the following line instead (if you're using an older SDK version, you can continue using retrieve_content).
let file_content = await (await client.files.content(file_object.id)).text()
// Include it in the request
let messages = [
{
"role": "system",
"content": "You are Kimi, an AI assistant provided by Moonshot AI. You excel in Chinese and English conversations. You provide users with safe, helpful, and accurate answers while rejecting any queries related to terrorism, racism, or explicit content. Moonshot AI is a proper noun and should not be translated.",
},
{
"role": "system",
"content": file_content,
},
{"role": "user", "content": "Please give a brief introduction to the content of moonshot.pdf"},
]
const completion = await client.chat.completions.create({
model: "kimi-k2.6",
messages: messages
});
console.log(completion.choices[0].message.content);
}
main();
- Upload the file to the Kimi server using the
/v1/files interface or the files.create API in the SDK;
- Retrieve the file content using the
/v1/files/{file_id} interface or the files.content API in the SDK. The retrieved content is already formatted in a way that our recommended model can easily understand;
- Place the extracted (and formatted) file content (not the file
id) in the messages list as a system prompt;
- Start asking questions about the file content;
Note again: Place the file content in the prompt, not the file id.
Q&A on Multiple Files
If you want to ask questions based on multiple files, it’s quite simple. Just place each file in a separate system prompt. Here’s how you can do it in code:
from typing import *
import os
import json
from pathlib import Path
from openai import OpenAI
client = OpenAI(
api_key="MOONSHOT_API_KEY", # Replace MOONSHOT_API_KEY with the API Key you obtained from the Kimi Open Platform
base_url="https://api.moonshot.ai/v1",
)
def upload_files(files: List[str]) -> List[Dict[str, Any]]:
"""
upload_files uploads all the provided files (paths) via the '/v1/files' interface and generates file messages from the extracted content. Each file becomes an independent message with a role of 'system', which the Kimi large language model can correctly identify.
:param files: A list of file paths to be uploaded. The paths can be absolute or relative, and should be passed as strings.
:return: A list of messages containing the file content. Add these messages to the Context, i.e., the messages parameter when calling the `/v1/chat/completions` interface.
"""
messages = []
# For each file path, we upload the file, extract its content, and generate a message with a role of 'system', which is then added to the final messages list.
for file in files:
file_object = client.files.create(file=Path(file), purpose="file-extract")
file_content = client.files.content(file_id=file_object.id).text
messages.append({
"role": "system",
"content": file_content,
})
return messages
def main():
file_messages = upload_files(files=["upload_files.py"])
messages = [
# We use the * syntax to unpack the file_messages, making them the first N messages in the messages list.
*file_messages,
{
"role": "system",
"content": "You are Kimi, an AI assistant provided by Moonshot AI. You excel in Chinese and English conversations. You provide users with safe, helpful, and accurate answers while rejecting any queries related to terrorism, racism, or explicit content. Moonshot AI is a proper noun and should not be translated.",
},
{
"role": "user",
"content": "Summarize the content of these files.",
},
]
print(json.dumps(messages, indent=2, ensure_ascii=False))
completion = client.chat.completions.create(
model="kimi-k2.6",
messages=messages,
)
print(completion.choices[0].message.content)
if __name__ == '__main__':

async function upload_files(files){

recognize the file content within these system messages.

*/
let messages = []

for (const file of files) {

Best Practices for File Management
In general, the file upload and extraction features are designed to convert files of various formats into a format that our recommended model can easily understand. After completing the file upload and extraction steps, the extracted content can be stored locally. In the next file-based Q&A request, there is no need to upload and extract the files again.
Since we have limited the number of files a single user can upload (up to 1000 files per user), we suggest that you regularly clean up the uploaded files after the extraction process is complete. You can periodically run the following code to clean up the uploaded files:
from openai import OpenAI
client = OpenAI(
api_key="MOONSHOT_API_KEY", # Replace MOONSHOT_API_KEY with the API Key you obtained from the Kimi Open Platform
base_url="https://api.moonshot.ai/v1",
)
file_list = client.files.list()
for file in file_list.data:
client.files.delete(file_id=file.id)
const OpenAI = require("openai")
client = OpenAI({
apiKey: "MOONSHOT_API_KEY", // Replace MOONSHOT_API_KEY with the API Key you obtained from the Kimi Open Platform
baseURL: "https://api.moonshot.ai/v1",
})
async function main() {
file_list = await client.files.list()
for (file of file_list.data) {
await client.files.delete(file_id=file.id)
}
}
main()
files.list API and then delete each file using the files.delete API. Regularly performing this operation ensures that file storage space is released, allowing subsequent file uploads and extractions to be successful.
