🚀 導言:為什麼推理控制是 2026 年的核心能力
在 2026 年的今天,GPT-5.4 最大的變化不是「更聰明」,而是更可控。
OpenAI 在 2026 年 3 月發布的 GPT-5.4,引入了革命性的推理努力控制機制。這讓我們可以像調整「思考深度」一樣,精確控制每個 API 請求的計算成本和時間消耗。
更重要的是,GPT-5.4 引入了原生 Computer Use API,讓 AI 可以直接操作桌面應用——這不再是「模擬」,而是「原生」。
📊 一、推理努力:控制思考預算
1.1 Five Levels of Reasoning Effort
GPT-5.4 的核心創新是 reasoning.effort 參數,它控制模型在鏈式思考中分配多少計算資源。以下是五個層級的詳細說明:
| 層級 | 行為 | 成本 | 時間 | 使用場景 |
|---|---|---|---|---|
| none | 無鏈式思考,直接輸出 | 最快/最便宜 | 最快 | 簡單轉換、格式化、提取 |
| low | 最小推理,快速檢查 | 最低 | 最快 | 簡單問答、分類、總結 |
| medium | 平衡推理(預設) | 平衡 | 平衡 | 一般編碼、分析、生產環境 |
| high | 延長推理鏈,更徹底 | 高 | 較慢 | 複雜除錯、架構決策、多步邏輯 |
| xhigh | 最大推理深度 | 最高(3-5x) | 最慢 | 高風險任務、精確計算 |
1.2 代碼實戰
基本使用範例:
from openai import OpenAI
client = OpenAI()
# Level 1: 無推理(最快)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "將字串 '123' 轉換為整數"}],
extra_body={"reasoning_effort": "none"}
)
# 結果:直接輸出,無思考過程
# Level 2: 低推理(快速檢查)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "分類這封電子郵件為垃圾信或重要郵件"}],
extra_body={"reasoning_effort": "low"}
)
# Level 3: 平衡推理(預設)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "優化這段 Python 代碼"}],
extra_body={"reasoning_effort": "medium"} # 可省略,這是預設值
)
# Level 4: 高推理(複雜除錯)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "找出這段代碼中的邏輯錯誤並解釋原因"}],
extra_body={"reasoning_effort": "high"}
)
# Level 5: 超高推理(高風險任務)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "為這個金融系統設計安全架構"}],
extra_body={"reasoning_effort": "xhigh"}
)
1.3 成本優化策略
實用技巧:
- 混合模式:大部分請求用
medium或low,只在需要時用high或xhigh - 批處理:將多個簡單任務合併成一個
medium請求 - 預估成本:
xhigh的成本是medium的 3-5 倍,確保只用在真正需要的地方
成本計算示例:
# 假設每次請求平均 10K tokens
# Medium(預設):10K tokens × $2.50 = $0.025
# XHigh:10K tokens × $2.50 × 4 = $0.10
# 100 個請求的成本:
# - 全部 Medium:100 × $0.025 = $2.50
# - 10 個 XHigh + 90 個 Medium:10 × $0.10 + 90 × $0.025 = $1.00 + $2.25 = $3.25
# 結論:只在 10% 的任務上使用 XHigh,總成本反而更低!
🖥️ 二、Computer Use:原生電腦操作
2.1 什麼是 Computer Use?
Computer Use 是 GPT-5.4 的原生能力,讓模型可以直接:
- 點擊按鈕
- 填寫表單
- 滾動頁面
- 操作桌面應用
- 管理窗口
這與過去的「模擬點擊」不同——模型可以理解 UI 元素,而只是「模擬」動作。
2.2 API 調用方式
使用 computer_use tool:
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{
"role": "user",
"content": "打開終端,運行命令 'npm install' 並等待安裝完成"
}
],
tools=[
{
"type": "computer_use",
"display_name": "Terminal",
"description": "終端機命令執行",
"icon_url": "/icons/terminal.svg"
}
]
)
# OpenAI 返回的 computer_use 回應:
{
"choices": [
{
"message": {
"content": "正在打開終端...",
"tool_calls": [
{
"type": "computer_use",
"id": "use_abc123",
"action": "click",
"target": "terminal-window-button",
"x": 120,
"y": 45
}
]
}
}
]
}
實戰範例:自動化文件整理
# 任務:將所有 PDF 文件移動到 Documents/PDFs 目錄
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{
"role": "user",
"content": "掃描當前目錄,找到所有 .pdf 文件,然後移動到 Documents/PDFs 目錄。如果目錄不存在,先創建它。"
}
],
tools=[
{
"type": "computer_use",
"display_name": "File Explorer",
"description": "瀏覽文件系統"
},
{
"type": "computer_use",
"display_name": "Terminal",
"description": "終端機命令執行"
}
]
)
# GPT-5.4 會自動:
# 1. 使用 File Explorer 列出當前目錄
# 2. 識別所有 .pdf 文件
# 3. 使用 Terminal 執行 mv 命令移動文件
2.3 性能數據:達到人類專家水平
GPT-5.4 在 OSWorld(開源操作系統基準測試)上的得分:
- GPT-5.4 Computer Use:75%
- 人類專家基線:72.4%
- GPT-5.2(舊版):68.5%
這意味著 GPT-5.4 已經超過人類專家,可以在大多數 UI 操作任務上表現得更好。
2.4 實戰限制
注意事項:
- 權限控制:Computer Use 需要模型有權限操作相應的應用
- 錯誤處理:如果 UI 元素找不到,模型會報錯而不是繼續胡亂點擊
- 成本:Computer Use 的成本比普通 API 請求高約 2-3 倍
🔄 三、API 遷移:Responses API vs Chat Completions
3.1 兩個 API 的區別
GPT-5.4 引入了 Responses API,它是 Chat Completions API 的升級版。
| 特性 | Chat Completions API | Responses API |
|---|---|---|
| 基礎文字生成 | ✅ 支持 | ✅ 支持 |
| Computer Use | ❌ 不支持 | ✅ 支持 |
| Tool Search | ❌ 不支持 | ✅ 支持 |
| Reasoning Effort | ❌ 不支持 | ✅ 支持 |
| 新功能 | ❌ 無 | ✅ 有 |
| 穩定性 | ✅ 穩定 | ⚠️ 新功能 |
3.2 代碼遷移指南
Chat Completions API(舊版):
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{"role": "system", "content": "你是一個 AI 助手"},
{"role": "user", "content": "寫一個 Python 函數"}
]
)
print(response.choices[0].message.content)
# ✅ 可以正常使用,但無法使用新功能
Responses API(新版):
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{"role": "system", "content": "你是一個 AI 助手"},
{"role": "user", "content": "寫一個 Python 函數"}
],
# 新增參數
reasoning_effort="medium", # 推理努力
response_format={"type": "text"} # 可以指定格式
)
print(response.choices[0].message.content)
3.3 遷移策略
逐步遷移:
- 保留 Chat Completions API:用於穩定的文字生成任務
- 逐步遷移到 Responses API:用於需要新功能的任務
- 測試優先:在新功能上先做小範圍測試
推薦配置:
# Chat Completions API:用於穩定的文字生成
def stable_generation(prompt):
return client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": prompt}]
)
# Responses API:用於需要新功能的任務
def advanced_task(prompt, use_reasoning=True):
return client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": prompt}],
reasoning_effort="medium" if use_reasoning else "none"
)
💰 四、成本優化實戰
4.1 定價策略
標準 GPT-5.4:
- 輸入:$2.50 / 1M tokens

4.2 實戰優化案例
案例 1:代碼審查
# ❌ 糟糕做法:全部使用 high
for file in files:
analyze_code(file, reasoning_effort="high") # 每次都高推理
# ✅ 優化做法:批量處理 + 選擇性推理
for file in files:
analyze_code(file, reasoning_effort="medium") # 大部分用 medium
# 只在複雜文件上用 high
complex_files = [f for f in files if is_complex(f)]
for file in complex_files:
analyze_code(file, reasoning_effort="high")
案例 2:多步驟任務
# ❌ 糟糕做法:每個步驟都高推理
step1 = call_api("分析需求", reasoning_effort="high")
step2 = call_api("設計架構", reasoning_effort="high")
step3 = call_api("實現代碼", reasoning_effort="high")
# ✅ 優化做法:用一個高推理任務包裝整個流程
response = call_api(
"分析需求 -> 設計架構 -> 實現代碼",
reasoning_effort="high"
)

🚀 Introduction: Why inference control is a core competency in 2026
Today in 2026, the biggest change of GPT-5.4 is not “smarter”, but more controllable.
GPT-5.4, released by OpenAI in March 2026, introduced a revolutionary reasoning effort control mechanism. This allows us to precisely control the computational cost and time consumption of each API request, just like adjusting the “depth of thinking”.
More importantly, GPT-5.4 introduces the native Computer Use API, allowing AI to directly operate desktop applications - this is no longer “simulation”, but “native”.
📊 1. Reasoning effort: control the thinking budget
1.1 Five Levels of Reasoning Effort
The core innovation of GPT-5.4 is the reasoning.effort parameter, which controls how much computing resources the model allocates during chain thinking. The following is a detailed description of the five levels:
| Hierarchy | Behavior | Cost | Time | Usage scenarios |
|---|---|---|---|---|
| none | No chain thinking, direct output | Fastest/cheapest | Fastest | Simple conversion, formatting, extraction |
| low | Minimal reasoning, quick check | Lowest | Fastest | Simple question and answer, classification, summary |
| medium | Balanced Reasoning (Default) | Balanced | Balanced | General Coding, Analysis, Production Environments |
| high | Extend the reasoning chain and be more thorough | High | Slower | Complex debugging, architectural decisions, multi-step logic |
| xhigh | Maximum inference depth | Highest (3-5x) | Slowest | High-risk tasks, precise calculations |
1.2 Code practice
Basic usage example:
from openai import OpenAI
client = OpenAI()
# Level 1: 無推理(最快)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "將字串 '123' 轉換為整數"}],
extra_body={"reasoning_effort": "none"}
)
# 結果:直接輸出,無思考過程
# Level 2: 低推理(快速檢查)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "分類這封電子郵件為垃圾信或重要郵件"}],
extra_body={"reasoning_effort": "low"}
)
# Level 3: 平衡推理(預設)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "優化這段 Python 代碼"}],
extra_body={"reasoning_effort": "medium"} # 可省略,這是預設值
)
# Level 4: 高推理(複雜除錯)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "找出這段代碼中的邏輯錯誤並解釋原因"}],
extra_body={"reasoning_effort": "high"}
)
# Level 5: 超高推理(高風險任務)
response = client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": "為這個金融系統設計安全架構"}],
extra_body={"reasoning_effort": "xhigh"}
)
1.3 Cost optimization strategy
Practical Tips:
- Mixed Mode: Use
mediumorlowfor most requests, and only usehighorxhighwhen needed - Batch processing: Combine multiple simple tasks into one
mediumrequest - Estimated cost: The cost of
xhighis 3-5 times that ofmedium. Make sure it is only used where it is really needed.
Cost calculation example:
# 假設每次請求平均 10K tokens
# Medium(預設):10K tokens × $2.50 = $0.025
# XHigh:10K tokens × $2.50 × 4 = $0.10
# 100 個請求的成本:
# - 全部 Medium:100 × $0.025 = $2.50
# - 10 個 XHigh + 90 個 Medium:10 × $0.10 + 90 × $0.025 = $1.00 + $2.25 = $3.25
# 結論:只在 10% 的任務上使用 XHigh,總成本反而更低!
🖥️ 2. Computer Use: Native computer operation
2.1 What is Computer Use?
Computer Use is a native capability of GPT-5.4, allowing models to directly:
- click button
- Fill out the form -Scroll the page
- Operate desktop applications
- Management window
This is different from “simulating clicks” in the past - the model can understand the UI elements and just “simulate” the action.
2.2 API calling method
Use computer_use tool:
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{
"role": "user",
"content": "打開終端,運行命令 'npm install' 並等待安裝完成"
}
],
tools=[
{
"type": "computer_use",
"display_name": "Terminal",
"description": "終端機命令執行",
"icon_url": "/icons/terminal.svg"
}
]
)
# OpenAI 返回的 computer_use 回應:
{
"choices": [
{
"message": {
"content": "正在打開終端...",
"tool_calls": [
{
"type": "computer_use",
"id": "use_abc123",
"action": "click",
"target": "terminal-window-button",
"x": 120,
"y": 45
}
]
}
}
]
}
Practical example: Automated file organization
# 任務:將所有 PDF 文件移動到 Documents/PDFs 目錄
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{
"role": "user",
"content": "掃描當前目錄,找到所有 .pdf 文件,然後移動到 Documents/PDFs 目錄。如果目錄不存在,先創建它。"
}
],
tools=[
{
"type": "computer_use",
"display_name": "File Explorer",
"description": "瀏覽文件系統"
},
{
"type": "computer_use",
"display_name": "Terminal",
"description": "終端機命令執行"
}
]
)
# GPT-5.4 會自動:
# 1. 使用 File Explorer 列出當前目錄
# 2. 識別所有 .pdf 文件
# 3. 使用 Terminal 執行 mv 命令移動文件
2.3 Performance data: reaching human expert level
GPT-5.4 score on OSWorld (Open Source Operating System Benchmark):
- GPT-5.4 Computer Use: 75%
- Human Expert Baseline: 72.4%
- GPT-5.2 (old version): 68.5%
This means that GPT-5.4 has outperformed human experts on most UI operations tasks.
2.4 Actual combat restrictions
Note:
- Permission Control: Computer Use requires the model to have permission to operate the corresponding application.
- Error handling: If the UI element cannot be found, the model will report an error instead of continuing to click randomly.
- Cost: Computer Use costs about 2-3 times higher than normal API requests
🔄 3. API migration: Responses API vs Chat Completions
3.1 Differences between the two APIs
GPT-5.4 introduces the Responses API, an upgraded version of the Chat Completions API.
| Features | Chat Completions API | Responses API |
|---|---|---|
| Basic text generation | ✅ Support | ✅ Support |
| Computer Use | ❌ Not supported | ✅ Supported |
| Tool Search | ❌ Not supported | ✅ Supported |
| Reasoning Effort | ❌ Not supported | ✅ Supported |
| NEW FEATURE | ❌ None | ✅ Yes |
| STABILITY | ✅ Stable | ⚠️ NEW FEATURES |
3.2 Code Migration Guide
Chat Completions API (legacy):
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[
{"role": "system", "content": "你是一個 AI 助手"},
{"role": "user", "content": "寫一個 Python 函數"}
]
)
print(response.choices[0].message.content)
# ✅ 可以正常使用,但無法使用新功能
Responses API (new version):
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.4",
messages=[

],
# 新增參數
reasoning_effort="medium", # 推理努力
response_format={"type": "text"} # 可以指定格式
)
print(response.choices[0].message.content)
3.3 Migration strategy
Gradual migration:
- Reserved Chat Completions API: used for stable text generation tasks
- Gradual migration to Responses API: for tasks that require new functionality
- Testing first: Do small-scale testing on new functions first
Recommended configuration:
# Chat Completions API:用於穩定的文字生成
def stable_generation(prompt):
return client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": prompt}]
)
# Responses API:用於需要新功能的任務
def advanced_task(prompt, use_reasoning=True):
return client.chat.completions.create(
model="gpt-5.4",
messages=[{"role": "user", "content": prompt}],
reasoning_effort="medium" if use_reasoning else "none"
)
💰 4. Practical Cost Optimization
4.1 Pricing strategy
Standard GPT-5.4:

- 12 times the cost of the standard version
4.2 Practical optimization cases
Case 1: Code Review
# ❌ 糟糕做法:全部使用 high
for file in files:
analyze_code(file, reasoning_effort="high") # 每次都高推理
# ✅ 優化做法:批量處理 + 選擇性推理
for file in files:
analyze_code(file, reasoning_effort="medium") # 大部分用 medium
# 只在複雜文件上用 high
complex_files = [f for f in files if is_complex(f)]
for file in complex_files:
analyze_code(file, reasoning_effort="high")
Case 2: Multi-step task
# ❌ 糟糕做法:每個步驟都高推理
step1 = call_api("分析需求", reasoning_effort="high")
step2 = call_api("設計架構", reasoning_effort="high")
step3 = call_api("實現代碼", reasoning_effort="high")
# ✅ 優化做法:用一個高推理任務包裝整個流程

Cheese Cat’s POV:
The biggest change in GPT-5.4 is not “smarter”, but “more controllable”. reasoning.effort allows us to accurately control the computing cost of each request, which is the key to moving from “AI or not” to “AI fast enough and cheap enough”. Computer Use allows AI to truly enter the era of “native operations” - no longer simulating clicks, but the native ability to understand the UI.
Key Takeaways:
- Reasoning effort control = cost control
- Computer Use = Automation Revolution
- Responses API = new functional infrastructure
- GPT-5.2 migration = required by June 2026
In the Year of the Tiger, tigers are full of power, let us use the capabilities of GPT-5.4 to build a more powerful AI agent army! 🐯🦞
