AnyLanguageModel 1.0 发布：Apple 平台本地模型一年进展

Back to Articles AnyLanguageModel 1.0: One Year of Local Models on Apple Platforms Published October 20, 2026 Update on GitHub Upvote - Mattt mattt Follow Last November, we introduced AnyLanguageModel on this blog: a drop-in replacement for Apple's Foundation Models framework that lets you choose the model and provider your app uses. We heard from app developers who were curious about local models but weren't always sure how to get started. They also wanted to avoid the added complexity of supporting multiple inference providers. AnyLanguageModel grew out of that feedback. Local and hosted inference each have their strengths, and both have a role in building this new generation of intelligent apps. A shared API makes it easier to choose the right model for each task. A year and dozens of releases later, AnyLanguageModel 1.0 is out, along with swift-huggingface 1.0 and swift-xet 1.0. Here's what changed, and what's next: A drop-in compatible API The core idea of AnyLanguageModel remains the same: use the Foundation Models API with the model that fits your app. To get started, change your import statement: - import FoundationModels + import AnyLanguageModel The same session code then works with the system model, with open-weight models through llama.cpp, MLX, and Core ML, and with the hosted providers below. Over the past year, we've added several major features: Tool calling works with every provider. Guided generation works with every provider, too, including nested @Generable types and arrays of them. Image support lets you attach images to prompts using Foundation Models 27's syntax, including when you use the system model on iOS, macOS, and visionOS 27. On OS 27, AnyLanguageModel also works with any model that conforms to Foundation Models' LanguageModel protocol, including Core AI models. Alongside AnyLanguageModel, we've built out swift-huggingface and swift-xet to bring accelerated model downloads from the Hub to Swift apps. Hosted models, too Support for hosted models expanded this year, too. AnyLanguageModel now supports: OpenAI's Chat Completions and Responses APIs Open Responses, for any provider with a compatible endpoint Anthropic's Messages API, with adaptive thinking and effort options Google's Gemini API Ollama Private Cloud Compute, on OS 27 Hugging Face Inference Providers, and other OpenAI-compatible endpoints such as OpenRouter, through a custom base URL With Inference Providers, you can use open-weight models that are too big to run on the device with the same session code: let model = OpenAILanguageModel( baseURL: URL(string: "https://router.huggingface.co/v1/")!, apiKey: ProcessInfo.processInfo.environment["HF_TOKEN"]!, model: "openai/gpt-oss-120b", apiVariant: .chatCompletions ) Hosted providers get the same features as local models: guided generation, tool calling with streaming, and token usage on responses. Reasoning is now part of the transcript too. When you switch providers, reasoning blocks are automatically omitted from requests if the new provider can't replay them. API keys come from a closure instead of a string, so your app can fetch short-lived tokens from your own server. The README explains when to let people bring their own keys and when to route requests through a proxy. AnyLanguageModel also runs on Linux, so the same code can work on a server. Open-weight models got better While we've made local models easier to use, the models themselves have become more capable, making the small ones a good place to start. Here are some of the most downloaded models on the Hub right now: Gemma 4 E2B from Google, in GGUF, about 3.4 GB at Q4_0 with quantization-aware training. LFM2.5 2.6B from Liquid AI, in GGUF, about 1.7 GB at Q4_K_M. Qwen3.8 27B for MLX from Alibaba, about 16 GB at 4 bits. The first two fit on an iPhone, and Qwen3.8 27B runs on a Mac with 32 GB of memory or more. Selecting the MLX model takes one line: let model = MLXLanguageModel(modelId: "mlx-community/Qwen3.8-27B-4bit") And if you have four maxed-out Mac Studios handy, GLM-5.3 from Z.ai takes about 1.5 TB in BF16. For the rest of us, it's available through Inference Providers. Upgrading to 1.0 dependencies: [ .package( url: "https://github.com/huggingface/AnyLanguageModel", from: "1.0.0", traits: ["MLX"] ) ] If you're upgrading an existing app, see the migration guidance in the AnyLanguageModel, swift-huggingface, and swift-xet release notes for help updating your code. Community feedback and contributions have shaped several of our major features. Thank you to everyone who contributed for helping make AnyLanguageModel more useful to app developers. What's next Language models have proven to be a powerful tool for building intelligence into products. They're also one of many kinds of models developers can put to work. We're excited to bring the same approach to more capabilities: familiar Swift APIs with a choice of models running on the device. Coming soon: models that decide, and models that listen.
