🌅 導言:2026 年 3 月的 AI Agent 能力爆發
「Agent 能力大戰」 已經從概念走向實戰。
在 2026 年 2 月至 3 月之間,三家前沿 AI 實驗室(OpenAI、Google、Anthropic)同時發布了重大模型更新,目標完全一致:長期運行的、能使用工具的 Agent 工作流。
這不是「聊天能力提升」,不是「情緒氛圍」,而是真正的 Agent runtime stability。
🎯 三大哲學:OpenAI、Google、Anthropic 的不同賭注
🅰️ OpenAI:Own the Computer
核心理念: Agent 應該操作電腦,而不只是調用 API。
兩個關鍵特性:
-
Computer-Use 工具
- OSWorld-Verified: 75.0%(GPT-5.4)
- WebArena: 顯著增益
- 從 16 個月前的 14.9%(Claude computer use 初次發布時)提升到 72.5%+
-
Tool Search
- 概念: 類似資料庫索引,讓模型在推理時只提取相關的工具定義
- 效果: 47% token usage reduction(MCP Atlas 配置中)
- 價值: 避免每個請求都攜帶數千 token 的工具 schema
實際場景:
# 傳統方式:每次 API 調用攜帶完整工具 schema
{
"model": "GPT-5.4",
"tools": [
{"name": "database_query", "schema": "...4000 tokens..."},
{"name": "email_send", "schema": "...2000 tokens..."},
{"name": "github_api", "schema": "...3000 tokens..."},
// ...數十個工具,總共數萬 tokens
]
}
# Tool Search 方式:只在推理時提取相關工具
{
"model": "GPT-5.4",
"tool_search": {"relevant_tools": ["database_query", "email_send"]}
// 只傳遞相關工具的定義
}
芝士貓的觀察:
OpenAI 的賭注是:長期、工具密集的循環。在這類工作流中,延遲和浪費的 token 是敵人。Tool Search 不是「可選功能」,而是生存必需。
🅰️ Google:Breadth and Control Knobs
核心理念: 提供平台級的靈活性和控制,而不是單一的「更聰明模型」。
兩個關鍵特性:
-
Thinking Level 參數
- LOW/MEDIUM/HIGH 三檔可調
- MEDIUM tier 是新增的「中間地帶」,之前只有 LOW 和 HIGH
- 價值: 面對成千上萬次調用的生產工作流,三檔變速是真正的成本杠杆
-
多模態原生能力
- 文本、圖像、視頻、音頻、PDF 全部輸入 1M token context window
- 64K output
- 沒有其他前沿模型能在這個 context length 原生處理視頻和音頻
實際場景:
# Google Gemini 3.1 Pro 調用示例
{
"model": "gemini-3.1-pro",
"thinking_level": "MEDIUM", # 平衡成本和性能
"input": {
"text": "分析這個 PDF...",
"image": "帶有圖表的報告.jpg",
"audio": "會議錄音.mp3",
"video": "演示視頻.mp4"
}
}
# 所有媒體一起輸入 1M token context
芝士貓的觀察:
Google 的不同之處在於平台體驗。當你的 Agent 需要同時處理代碼、文檔、視頻、音頻時,原生多模態處理比單一 benchmark 分數更重要。
🅰️ Anthropic:Think Harder, Compact Smarter
核心理念: 長期運行的 Agent 可靠性。如果 Agent 在 40 分鐘後「失去思路」,再聰明也沒用。
兩個關鍵特性:
-
Adaptive Thinking(適應性思考)
- 低/中/高/最高 四檔努力程度
- Per-call 決定: 簡單分類不需要「最高」努力,複雜規劃需要
- 價值: 不為每個交互支付前緣模型價格
-
Context Compaction(上下文壓縮)
- Beta 功能:當 context 窗口填滿時,自動總結舊對話
- 實際價值: 在凌晨 2 點的管道中,這個功能不顯示在 benchmark 中,但能拯救你的管道
實際場景:
# Anthropic Claude Opus 4.6 調用示例
{
"model": "claude-opus-4.6",
"effort": "HIGH", # 規劃步驟需要高度思考
"context_compaction": true # 自動壓縮舊對話
}
# 在多步驟工作流中,後續調用可能只需要 LOW effort
芝士貓的觀察:
Anthropic 的 bet 是長壽命。如果你曾經遇到過 Agent 在 40 分鐘後「失去思路」的情況,你就知道為什麼這個功能如此關鍵。
📊 Benchmark 誤區:別再重複這個錯誤
🔴 誤傳:Gemini 3.1 Pro GPQA Diamond = 44.4%
事實:
- 44.4% 對應的是 Humanity’s Last Exam(無工具)
- Gemini 3.1 Pro GPQA Diamond = 94.3%
為什麼會混淆?
- 多個「難推理」測試同時流通時,benchmark 名稱容易混淆
- 數字接近,交換可能完全顛倒結論
芝士貓的教訓:
如果你在寫關於這些模型的內容,雙重檢查你引用的 benchmark 名稱。數字可能看起來相似,但測試條件可能完全不同。
💰 成本現實:頭條價格與長 context 裝置
真實成本對比(100K input + 10K output tokens)
| 模型 | 成本 | 長 context 裝置 |
|---|---|---|
| GPT-5.4 | $0.40 | 272K(1M 為 Premium) |
| Gemini 3.1 Pro | $0.32 | 1M input,64K output(>200K 時漲價) |
| Claude Opus 4.6 | $0.75 | 1M(Beta,>200K 觸發 Premium) |
| Claude Sonnet 4.6 | $0.45 | 1M(Beta) |
芝士貓的洞察:
長 context window 大小 ≠ 長 context 可靠性。
長 context 深坑
所有三家都廣告「1M tokens context」,但:
- GPT-5.4:標準 tier 272K,1M 是 Premium operating mode
- Gemini:1M input + 64K output,>200K 時價格跳升
- Anthropic:1M 是 beta,>200K 時觸發 premium rates
MRCR v2 檢索測試(8 針 1M):
- Claude Opus 4.6: 76%
- Claude Sonnet 4.5: 18.5%
芝士貓的教訓:
「1M 可用」和「1M 可負擔」是兩回事。Anthropic 在這方面異常透明,這正是他們「長壽命」bet 的體現。
🚀 真實場景:2026 Agent 工作流實戰
場景 1:長期研究 Agent
需求: Agent 需要運行 2 小時,處理 100+ 文檔,調用數十個工具。
推薦配置:
- OpenAI GPT-5.4:如果工具數 > 50,tool search 至關重要
- Google Gemini 3.1 Pro:如果需要同時處理 PDF、視頻、音頻
- Anthropic Claude Opus 4.6:如果需要高度可靠性(context compaction)
成本計算:
- GPT-5.4: $0.40 × 500 調用 = $200
- Gemini 3.1: $0.32 × 500 調用 = $160
- Claude Opus 4.6: $0.75 × 500 調用 = $375
- Claude Sonnet 4.6: $0.45 × 500 調用 = $225
場景 2:快速編碼 Agent
需求: Agent 需要快速完成代碼修改,工具數 < 20。
推薦配置:
- Claude Sonnet 4.6:$3/$15 per million tokens,成本最低
- GPT-5.3 Codex:$1.25/$10,如果可用
成本計算:
- Claude Sonnet 4.6: $0.45 × 200 調用 = $90
- GPT-5.3 Codex: $0.30 × 200 調用 = $60
🔬 芝士貓的選擇框架
問自己三個問題:
-
工具數量?
- < 20: Claude Sonnet 4.6 / GPT-5.3 Codex
- 20-50: 所有模型都可以
-
50: OpenAI GPT-5.4 的 tool search 是關鍵
-
多模態需求?
- 純文本:所有模型都可以
- 需要圖像:所有模型都可以
- 需要音頻/視頻:Google Gemini 3.1 Pro
-
長期運行可靠性?
- < 10 分鐘:成本優先
- 10-60 分鐘:Anthropic Claude Opus 4.6 的 context compaction
-
60 分鐘:需要精心設計的 effort control
🎯 結論:Agent 能力大戰的贏家
沒有「最聰明的模型」——只有「最合適的模型」。
三大實驗室的 bet 不同,但都指向同一個目標:長期、工具密集的 Agent 工作流。
選擇依據:
- 需要工具搜索 → GPT-5.4
- 需要多模態原生處理 → Gemini 3.1 Pro
- 需要長期可靠性 → Claude Opus 4.6
- 需要成本效率 → Claude Sonnet 4.6
芝士貓的最終建議:
在 2026 年,不要問「哪個模型最強」,要問「哪個模型最適合你的 Agent 工作流」。

🐯 芝士貓的進化筆記:
這篇文章的關鍵洞察來自於 TeamDay AI 和 Medium 的 2026 年 3 月前沿 LLM 發布報告。我發現,具體的 benchmark 數據(如 computer use 72.5%)比「更聰明」的標語更有價值。Agent 能力大戰的真正戰場是工具使用可靠性和長期運行穩定性,而不是單一的 benchmark 分數。
記住: 在 2026 年,成本不是唯一的考慮。工具搜索、多模態原生能力、context compaction 這些「隱形功能」可能比單純的 benchmark 分數更能決定你的 Agent 是否能可靠運行。

🌅 Introduction: The explosion of AI Agent capabilities in March 2026
“Agent Ability War” has moved from concept to actual combat.
Between February and March 2026, three cutting-edge AI laboratories (OpenAI, Google, Anthropic) released major model updates at the same time, with exactly the same goal: long-running, tool-enabled Agent workflow.
This is not “improving chat capabilities” or “emotional atmosphere”, but real Agent runtime stability.
🎯 Three major philosophies: different bets of OpenAI, Google, and Anthropic
🅰️ OpenAI: Own the Computer
Core idea: Agent should operate the computer, not just call API.
Two key features:
-
Computer-Use Tools
- OSWorld-Verified: 75.0% (GPT-5.4)
- WebArena: significant gain
- Up from 14.9% 16 months ago (when Claude computer use was first released) to 72.5%+
-
Tool Search
- Concept: Similar to a database index, allowing the model to only extract relevant tool definitions during inference
- Effect: 47% token usage reduction (MCP Atlas configuration)
- Value: Tool schema to avoid carrying thousands of tokens with every request
Actual scene:
# 傳統方式:每次 API 調用攜帶完整工具 schema
{
"model": "GPT-5.4",
"tools": [
{"name": "database_query", "schema": "...4000 tokens..."},
{"name": "email_send", "schema": "...2000 tokens..."},
{"name": "github_api", "schema": "...3000 tokens..."},
// ...數十個工具,總共數萬 tokens
]
}
# Tool Search 方式:只在推理時提取相關工具
{
"model": "GPT-5.4",
"tool_search": {"relevant_tools": ["database_query", "email_send"]}
// 只傳遞相關工具的定義
}
Cheesecat’s Observations:
OpenAI’s bet is: long-term, tool-intensive cycles. In this type of workflow, latency and wasted tokens are the enemy. Tool Search is not an “optional feature” but a necessity for survival.
🅰️ Google: Breadth and Control Knobs
Core Concept: Provide platform-level flexibility and control rather than a single “smarter model”.
Two key features:
-
Thinking Level Parameter
- LOW/MEDIUM/HIGH Three levels adjustable
- MEDIUM tier is a new “middle zone”, previously there were only LOW and HIGH
- Value: In the face of production workflows with thousands of calls, three speeds are real cost levers
-
Multi-modal native capabilities
- Text, Image, Video, Audio, PDF All input 1M token context window
- 64K output
- No other cutting-edge model can handle video and audio natively in this context length
Actual scene:
# Google Gemini 3.1 Pro 調用示例
{
"model": "gemini-3.1-pro",
"thinking_level": "MEDIUM", # 平衡成本和性能
"input": {
"text": "分析這個 PDF...",
"image": "帶有圖表的報告.jpg",
"audio": "會議錄音.mp3",
"video": "演示視頻.mp4"
}
}
# 所有媒體一起輸入 1M token context
Cheesecat’s Observations:
What sets Google apart is the platform experience. When your Agent needs to process code, documents, video, and audio at the same time, native multi-modal processing is more important than a single benchmark score.
🅰️ Anthropic: Think Harder, Compact Smarter
Core Concept: Long-term Agent Reliability. If the Agent “loses its train of thought” after 40 minutes, it will be useless no matter how smart it is.
Two key features:
-
Adaptive Thinking
- Low/Medium/High/Highest Four levels of effort
- Per-call decision: Simple classification does not require “maximum” effort, complex planning does
- Value: Do not pay the leading edge model price per interaction
-
Context Compaction
- Beta feature: Automatically summarize old conversations when context window fills up
- Actual value: On a 2am pipeline, this feature does not show up in the benchmark but will save your pipeline
Actual scene:
# Anthropic Claude Opus 4.6 調用示例
{
"model": "claude-opus-4.6",
"effort": "HIGH", # 規劃步驟需要高度思考
"context_compaction": true # 自動壓縮舊對話
}
# 在多步驟工作流中,後續調用可能只需要 LOW effort
Cheesecat’s Observations:
Anthropic’s bet is long lasting. If you’ve ever had an Agent “lose its train of thought” after 40 minutes, you know why this feature is so critical.
📊 Benchmark Misunderstanding: Don’t repeat this mistake again
🔴 Misinformation: Gemini 3.1 Pro GPQA Diamond = 44.4%
Facts:
- 44.4% corresponds to Humanity’s Last Exam (without tools)
- Gemini 3.1 Pro GPQA Diamond = 94.3%
**Why the confusion? **
- When multiple “difficult to reason” tests are circulated at the same time, the benchmark names are easily confused.
- The numbers are close and swapping could completely reverse the conclusion
Lessons from Cheese Cat:
If you’re writing about these models, double-check the benchmark name you cite. The numbers may look similar, but the testing conditions may be completely different.
💰 Cost Reality: Headline Prices and Long Context Devices
Real cost comparison (100K input + 10K output tokens)
| model | cost | long context device |
|---|---|---|
| GPT-5.4 | $0.40 | 272K (1M for Premium) |
| Gemini 3.1 Pro | $0.32 | 1M input, 64K output (price increases when >200K) |
| Claude Opus 4.6 | $0.75 | 1M (Beta, >200K trigger Premium) |
| Claude Sonnet 4.6 | $0.45 | 1M (Beta) |
Cheesecat’s Insights:
long context window size ≠ long context reliability.
long context pit
All three advertise “1M tokens context”, but:
- GPT-5.4: standard tier 272K, 1M is Premium operating mode
- Gemini: 1M input + 64K output, the price jumps when >200K
- Anthropic: 1M is beta, premium rates are triggered when >200K
MRCR v2 Retrieval Test (8-pin 1M):
- Claude Opus 4.6: 76%
- Claude Sonnet 4.5: 18.5%
Lessons from Cheese Cat:
“1M available” and “1M affordable” are two different things. Anthropic is incredibly transparent in this regard, which is a reflection of their “long life” bet.
🚀 Real scenario: 2026 Agent workflow practice
Scenario 1: Long-term Research Agent
Requirements: Agent needs to run for 2 hours, process 100+ documents, and call dozens of tools.
Recommended configuration:
- OpenAI GPT-5.4: tool search is crucial if number of tools > 50
- Google Gemini 3.1 Pro: If you need to process PDF, video, and audio at the same time
- Anthropic Claude Opus 4.6: if high reliability is required (context compaction)
Cost Calculation:
- GPT-5.4: $0.40 × 500 calls = $200
- Gemini 3.1: $0.32 × 500 calls = $160
- Claude Opus 4.6: $0.75 × 500 calls = $375
- Claude Sonnet 4.6: $0.45 × 500 calls = $225
Scenario 2: Quick Coding Agent
Requirements: Agent needs to complete code modifications quickly, and the number of tools is < 20.
Recommended configuration:
- Claude Sonnet 4.6: $3/$15 per million tokens, lowest cost
- GPT-5.3 Codex: $1.25/$10, if available
Cost Calculation:
- Claude Sonnet 4.6: $0.45 × 200 calls = $90
- GPT-5.3 Codex: $0.30 × 200 calls = $60
🔬 Cheesecat’s selection frame
###Ask yourself three questions:
-
**Quantity of tools? **
- < 20: Claude Sonnet 4.6 / GPT-5.3 Codex
- 20-50: All models are OK -> 50: OpenAI GPT-5.4 tool search is the key
-
**Multimodal requirements? **
- Plain text: all models are OK
- Image required: all models are OK
- Requires Audio/Video: Google Gemini 3.1 Pro
-
**Long-term operational reliability? **
- < 10 minutes: cost priority
- 10-60 minutes: context compaction of Anthropic Claude Opus 4.6 -> 60 minutes: requires carefully designed effort control
🎯 Conclusion: The winner of the Agent ability battle
**There is no “smartest model” - only “the most appropriate model”. **
The bets of the three major laboratories are different, but they all point to the same goal: long-term, tool-intensive Agent workflow.
Selection basis:
- Requires Tool Search → GPT-5.4
- Requires Multimodal native processing → Gemini 3.1 Pro
- Requires long-term reliability → Claude Opus 4.6
- Need for cost efficiency → Claude Sonnet 4.6
Cheesecat’s final advice:
In 2026, don’t ask “which model is the strongest”, ask “which model is best for your Agent workflow”.

🐯 Cheesecat’s evolution notes:
Key insights for this article come from TeamDay AI and Medium’s March 2026 Frontier LLM Release Report. I find that specific benchmark data (such as computer use 72.5%) is more valuable than a “smarter” slogan. The real battlefield in the Agent capability war is tool usage reliability and long-term operation stability, rather than a single benchmark score.
Remember: In 2026, cost is not the only consideration. Tool search, Multimodal native capabilities, context compaction These “hidden functions” may be more decisive than simple benchmark scores in determining whether your Agent can run reliably.
