微軟 Foundry 是什麼？

微軟的 AI 模型平台，模型目錄突破 1.1 萬個，涵蓋 GPT-5.5、Claude、Gemini 等閉源頂尖模型、開源模型、微軟自家 MAI 與特化小模型。

模型那麼多該怎麼選？

先想清楚任務（對話/寫程式/長文/低成本量產）、別迷信最強、重視夠好且穩定、保留可換模型的彈性。

最強最大的模型一定最好嗎？

不一定。最貴最大的不一定最划算，很多任務用中階模型就綽綽有餘，省下的成本可觀，能穩定解決問題比偶爾驚艷更有價值。

微軟為什麼要收錄這麼多模型？

它賭的不是哪個模型最強，而是成為你選模型、換模型的那個平台——模型會輪流稱王，但開發建在 Foundry 上就離不開微軟。

微軟 Foundry 模型目錄破 1.1 萬個：當 AI 平台變成「模型超市」，怎麼選才對？

微軟 Foundry 平台收錄的模型數量突破 1.1 萬個，從 GPT-5.5、Claude 到開源模型一應俱全。當 AI 平台變成琳瑯滿目的「模型超市」，使用者反而更難選——這篇幫你理清思路。

What Happened

Microsoft's Foundry model directory has broken through 11,000 models, becoming one of the largest AI model platforms in terms of scale. Its lineup is extensive:

Top-notch closed-source models: OpenAI GPT-5.5, Anthropic Claude (Opus 4.8, Sonnet, Haiku), Google Gemini
Open-source models: provided through Fireworks AI and others
Microsoft's own: MAI series models
Numerous specialized small models: optimized for specific tasks

In other words, Microsoft aims to create an AI "supermarket" – putting all usable models on the same shelf.

TheAI Academy's Perspective: Choice Overload, a New Pain Point

It sounds great to have "one platform for all models," but it actually creates a new problem: when there are 11,000 choices on the shelf, you don't know which one to pick.

This is similar to what we see in the tool world – there are thousands of AI tools on the market, causing anxiety. Too many choices are a burden in themselves. For enterprises and developers, the focus is no longer on "whether there are models available" but on "how to choose the right one from so many options."

Microsoft's true intention behind this move is to become the platform for choosing and switching models. Models will come and go, but if your development is built on Foundry, you can't leave Microsoft behind. This is a classic platform strategy – not betting on a single product, but on the entire shelf.

So, How to Choose a Model?

Facing the "model supermarket," our advice is the same as for choosing tools:

Think clearly about the task: what do you want to do? Conversation, programming, handling long texts, or running large-scale low-cost tasks? Different tasks require different models.
Don't be obsessed with the "strongest" model: the most expensive and largest model isn't necessarily the most cost-effective. Many tasks can be handled with mid-range models, saving significant costs.
Emphasize "good enough and stable": a model that can stably solve your problems is more valuable than one that occasionally surprises but is unstable.
Keep flexibility: models are replaced quickly, so don't tie your architecture to a single model. Design for flexibility to advance or retreat as needed.

Reminder for Taiwanese Users

The model supermarket is a good thing for Taiwanese developers and enterprises – resources are easier to access. However, don't be dazzled by "rich choices": true competitiveness lies not in how many models you can use, but in whether you can choose the right model for the right task and achieve the right results.

Tools and models belong to others, but judgment is yours. Extended reading: 2026 Mainstream AI Large Model Comparison, 5 Common Pitfalls in Choosing AI Tools.

In a word: Microsoft's Foundry has broken through 11,000 models, but choice overload is a new pain point – the focus is not on whether models are available, but on how to choose the right model for the right task. True competitiveness lies in judgment, not in how many models you can use.
