Platform and Service Matrix

This page answers only two questions:

1. Which platforms the current code actually supports
2. Which service category each platform supports

Note: this page is governed by the current AiService implementation, not estimated from the README, examples, or future plans.

1. Platform enum

The current platform enum is defined in PlatformType (14 in total):

• OPENAI
• ANTHROPIC
• ZHIPU
• DEEPSEEK
• MOONSHOT
• HUNYUAN
• LINGYI
• OLLAMA
• MINIMAX
• BAICHUAN
• DASHSCOPE
• DOUBAO
• JINA
• SUNO

One caveat: the existence of a platform enum does not mean it automatically supports every service surface. The actual support relationship still depends on whether AiService.create*Service(...) has a matching branch.

2. Current service support matrix

3. What this matrix really tells you

Chat is the broadest main line

Almost every platform capability lands on the Chat entry point first, which makes it the most general-purpose model access main line today.

Responses is a clearly present but narrower second main line

Currently supported only on:

• OpenAI
• Doubao
• DashScope

This means Responses in AI4J is not an "every platform should automatically have it" alternative interface, but rather a more focused structured-access main line.

Messages is the third main line, on the Anthropic protocol

Currently only ANTHROPIC is supported (native IMessagesService). It lets systems that already speak the Anthropic dialect integrate native-in / native-out (zero OpenAI conversion), and reuses the same IMessagesService to reach Claude and partner vendors' Anthropic-compatible endpoints (Zhipu / MiniMax coding-plan). The ANTHROPIC platform also keeps a Chat entry point (a unified IChatService adapter that translates OpenAI format). See Messages (Anthropic native).

Embedding / Audio / Realtime are even narrower

• Embedding: OpenAI / Ollama only
• Audio: OpenAI only
• Realtime: OpenAI only

This shows that these service surfaces, although officially part of the SDK, are not disguised as fully symmetric cross-platform capabilities.

Video / Music are independent service surfaces with async submit → poll

• Video: OpenAI only (IVideoService: create / retrieve / content / remix)
• Music: Suno only (IMusicService: submitMusic / submitLyrics / fetch)

Unlike the synchronous / streaming semantics of Chat and Image, both follow an async lifecycle of submit task → poll status → pull result, and the SDK does not build in auto-polling. The SUNO platform currently exists only for the Music surface; every other service is unsupported. See Video interface and Music interface.

Rerank is an independent matrix

Currently supported only on:

• Jina
• Ollama
• Doubao

This shows that retrieval-related capabilities do not always come bundled with the Chat provider; in real engineering you frequently need to separate the "chat provider" from the "rerank provider".

4. The unified entry point stays consistent

Although the matrix is asymmetric, the call entry point stays unified:

AiService aiService = new AiService(configuration);

IChatService chat = aiService.getChatService(PlatformType.OPENAI);
IResponsesService responses = aiService.getResponsesService(PlatformType.DOUBAO);
IMessagesService messages = aiService.getMessagesService(PlatformType.ANTHROPIC);
IEmbeddingService embedding = aiService.getEmbeddingService(PlatformType.OLLAMA);
IRerankService rerank = aiService.getRerankService(PlatformType.JINA);
IImageService image = aiService.getImageService(PlatformType.DOUBAO);
IVideoService video = aiService.getVideoService(PlatformType.OPENAI);
IMusicService music = aiService.getMusicService(PlatformType.SUNO);

note

If a platform does not support a service, the current implementation throws directly:

• IllegalArgumentException("Unknown platform: ...")

In other words, unsupported does not mean "silent degradation", but explicit failure.

5. How it combines with the multi-instance registry

If you need to manage multiple provider instances within one application, you typically combine it with:

• AiServiceRegistry

e.g.:

IChatService tenantA = aiServiceRegistry.getChatService("tenant-a-openai");
IChatService tenantB = aiServiceRegistry.getChatService("tenant-b-doubao");
IRerankService rerank = aiServiceRegistry.getRerankService("tenant-rerank");

The point here is not "fetch an object by id", but rather that you can explicitly organize the asymmetric provider capability matrix into a multi-instance routing graph, instead of scattering platform selection across your business code.

6. Mistakes to avoid when reading this matrix

Don't treat PlatformType as a capability guarantee

The platform enum is only a candidate set; what is actually supported must be checked against the AiService dispatch implementation.

Don't assume Responses is a full-coverage replacement for Chat

The current matrix already shows it is not.

Don't tie the retrieval-chain provider to the chat provider

The Rerank support matrix is independent on its own.

7. Conclusion of this page

AI4J's current unification is not about full symmetry of platform capabilities, but rather that it explicitly maintains an asymmetric yet clear service matrix through a unified entry point. Understanding this matrix matters more than memorizing any single provider's example, because it directly determines whether you can correctly design the engineering boundaries for a multi-platform, multi-service system.
