向 Workers AI 目錄新增新的 LLM、文字分類和程式碼產生模型

在過去的幾個月裡，Workers AI 團隊一直在努力改進我們的 AI 平台。我們於 9 月推出了該平台；11 月，我們新增了更多模型，例如 Code Llama、Stable Diffusion、Mistral，以及串流和更長的上下文視窗等改進。

今天，我們很高興地宣布推出八種新模型。

下面重點介紹了新的模型，如要瞭解我們包含 20 多個模型的完整模型目錄，請查看我們的開發人員文件。

文字產生@hf/thebloke/llama-2-13b-chat-awq@hf/thebloke/zephyr-7b-beta-awq@hf/thebloke/mistral-7b-instruct-v0.1-awq@hf/thebloke/openhermes-2.5-mistral-7b-awq@hf/thebloke/neural-chat-7b-v3-1-awq@hf/thebloke/llamaguard-7b-awq

程式碼產生@hf/thebloke/deepseek-coder-6.7b-base-awq@hf/thebloke/deepseek-coder-6.7b-instruct-awq

為您帶來最好的開放原始碼

我們的使命是支援各種開放原始碼模型和工作。為此，我們很高興地宣佈可在 Cloudflare 網路上部署的最新模型和功能預覽。

其中一個突出的模型是 deep-seek-coder-6.7b，與同類 Code Llama 模型相比，它在流行基準測試中的得分明顯高出約 15%。這一效能優勢歸功於其多樣化的訓練資料，其中包括英文和中文程式碼產生資料集。此外，openhermes-2.5-mistral-7b 模型展示了高品質微調資料集如何提高基礎模型的準確性。在許多 LLM 基準測試中，這款 Mistral 7b 微調模型的表現比基礎模型高出約 10%。

我們還推出了採用啟動感知權重量化 (AWQ) 的創新模型，例如 llama-2-13b-awq。這種量化技術只是提高大型語言模型記憶體效率的策略之一。雖然量化通常會提高 AI 模型的推斷效率，但這樣做往往是以犧牲精度為代價的。AWQ 找到了一種平衡來緩解這種權衡。

AI 的進步速度令人難以置信，但 Cloudflare 的 Workers AI 透過最新模型簡化了入門。我們處理最新的進展，並使其可以透過 Worker 或我們的 HTTP API 輕鬆存取。您只需一個 API 呼叫或 Workers 繫結即可獲得尖端模型。簡而言之，Workers AI 允許開發人員專注于提供卓越的使用者體驗，而無需擔心部署、基礎架構或可擴展性問題。

使用 AI 保護您的應用程式

我們透過此模型目錄更新支援的一個較新的使用案例是使用 llamaguard-7b-awq 對提示和回應進行分類和檢查。我們都聽說過 AI 機器人無意中給出可能不適當或有害答案的故事。這個新的 LlamaGuard 模型允許開發人員在提示或回應可能不安全時進行偵測和分類，從而使他們能夠使用開發人員定義的類別控制其應用程式的輸入和輸出。

以下是一個應用程式範例，該應用程式接受使用者輸入並將其與一組定義的不安全類別範例進行比較，以確定輸入是否安全。您可以根據您的使用案例自訂內容類別。以下範例類別僅供參考，Cloudflare 不對 Llama Guard 的效能或任何結果做出任何保證。
