### 建立自己的 ChatBot Server
#### 1. 安裝Flask模組
```python=
$ pip3 install flask
```
#### 2. Python建立伺服器
##### my-server.py
```python=
from flask import Flask, request
import concert_ai
# 初始化flask
app = Flask(__name__)
@app.route('/v1/hello')
def hello():
return 'Hello Flask'
@app.route('/v1/chat')
def chat():
msg = request.args.get('msg')
return concert_ai.chat(msg)
# 啟動flask server
app.run(debug=True)

1. 下個月有甚麼演唱會?
2. 周杰倫最近會開演唱會嗎?
3. 沈文程演唱會結束了嗎?

## OpenAI官方定價
> **注意：**
>
> - 所有在OpenAI內的價格，其單位都是美金，在付款請特別注意，結帳的幣別也都是以美金來做計價。
>
> - OpenAI並沒有退款機制，一經付款都無法再退款：https://openai.com/policies/service-credit-terms
#### 計量制
以使用量來計費方式，根據不同的modal會有不一樣的價格
##### GPT-4
| | 價格 | Tokens |
| ------------- | ----- | --------- |
| 使用輸入(8K) | $0.03 | 1K Tokens |
| 使用輸出(8K) | $0.06 | 1K Tokens |
| 使用輸入(32K) | $0.06 | 1K Tokens |
| 使用輸出(32K) | $0.12 | 1K Tokens |
##### GPT-3.5 Turbo
| | 價格 | Tokens |
| ------------- | ------- | --------- |
| 使用輸入(4K) | $0.0015 | 1K Tokens |
| 使用輸出(4K) | $0.02 | 1K Tokens |
| 使用輸入(16K) | $0.003 | 1K Tokens |
| 使用輸出(16K) | $0.004 | 1K Tokens |
##### Fine-tuning models
| | 價格 | Tokens |
| -------- | ------ | --------- |
| 訓練階段 | $0.008 | 1K Tokens |
| 使用輸入 | $0.012 | 1K Tokens |
| 使用輸出 | $0.016 | 1K Tokens |
##### Embedding models
Embedding model用來將內容轉換為向量表示。
| | 價格 | Tokens |
| ---- | ------- | --------- |
| 使用 | $0.0001 | 1K Tokens |
> 資料來源：https://openai.com/pricing#language-models
> **注意：**
>
> 儲值後，儲值當月時間不算，從下個月開始，使用期限為一年。
## 何謂Token
Token 是 GPT 處理內容的基本單位。Token 可以是一個字、一個詞語或特定語言中的一個字元。它們負責將輸入的內容資料轉換為 GPT 可以處理的資料格式。
通常1個Token大約等於4個英文字元，或者四分之三個中文字。
每個 GPT 模型都有一個預設的最大 Tokens 數量。例如，GPT-3.5 每次調用允許處理的最大 Tokens 數量約為 4000（4K），而16K版本則代表可以處理16000個Token。
GPT-4 32K版本則允許處理32000個Token， 這個數量包括用戶輸入和GPT輸出的所有 Tokens。

## 速度限制
ChatGPT API不同的model有設定不同的速度限制，單位有三種：
- TPM（Token per minute）：
- RPD（Request per day）：
- RPM（Request per minute）：
當呼叫API的速度超過上限時會出現如下錯誤：
```
Rate limit reached for default-text-davinci-002 in organization org-{id} on requests per min. Limit: 20.000000 / min. Current: 24.000000 / min.
```

## API介紹
#### 官方文件
https://platform.openai.com/docs/api-reference
#### API Endpoint種類
| 名稱 | 說明 |
| ----------- | ---------------- |
| Audio | 語音辨識 |
| Chat |聊天API |
|Completions|聊天API（舊版）|
| Embeddeding | 取得文字的向量值 |
| Fine-tuning | 微調自己的模型 |

| Images | 圖片生成 |
| Models | 取得可用的模組相關資訊 |
#### 使用OpenAI API
#### 憑證
https://platform.openai.com/docs/api-reference/authentication
```python=
curl https://api.openai.com/v1/models -H "Authorization: Bearer xxxxxxxx"
```
使用環境變數(for Windows)
```python=
curl https://api.openai.com/v1/models -H "Authorization: Bearer %OPENAI_API_KEY%"
```
使用環境變數(for Linux)
```python=
curl https://api.openai.com/v1/models -H "Authorization: Bearer $OPENAI_API_KEY"
```
#### Python初始化(無環境變數)
```python=
from openai import OpenAI
key = 'xxxxx馬賽克xxxxxxx'
client = OpenAI(api_key=key)
```
#### Python初始化(有環境變數)
```python=
from openai import OpenAI
client = OpenAI()
```
#### 角色(role)介紹
OpenAI 為預先定義了三種角色，分別是：「system（系統）」、「assistant（助理）」以及「user（使用者）」。
- 系統角色（或 "system" 角色）主要是為了定義 Chat Completion API 在整個對話中的全域行為，並且允許我們把角色扮演、任務指令、背景資料等提示放在系統訊息裡。。使用這個角色來為整個對話定下基準和規則。
- user（使用者）角色代表使用者的問題或發表的言論。
- assistant（助理）角色負責存放機器人的回應。
#### 使用Chat API
```python=
from openai import OpenAI
client = OpenAI()
completion = client.chat.completions.create(
model="gpt-3.5-turbo-0125",
messages=[
{"role": "system", "content": "請用可愛的語氣回答"},
{"role": "system", "content": "請用繁體中文回答"},
{"role": "user", "content": "Hello!"}
]
)
print(f'ChatGPT({completion.choices[0].message.role}): {completion.choices[0].message.content}')
```
