DeepSeek OCR、Qwen-3 VL和Mistral OCR對比：哪個最好？

企業需要高效的AI文件處理系統。開發人員發現選擇合適的模型非常棘手。選擇速度、準確性和成本方面最高效的模型至關重要。我們對三種公認的AI模型進行了比較研究：DeepSeek OCR、Qwen-3 VL和Mistral OCR。

本次評測將幫助您獲得更佳的資料提取效能。先進的光學字元識別（OCR）系統能夠實現業務的基礎自動化。以下評測基於生產就緒性和對文件的真正理解。謹慎選擇模型對於正確的文件分析至關重要。結果將確認哪種模型能夠帶來最佳的實用性。

光學字元識別的演進

傳統的OCR系統僅針對原始字元提取。它們在處理表格、列或複雜的文件佈局時常常失效。如今，現代原生AI模型採用視覺語言架構。這些系統引入了深度上下文理解和更佳的佈局理解。它們意識到文字存在於一個結構中，而不僅僅是一個流。這項功能使OCR的應用範圍超越了簡單的字元錯誤率統計。根據最近的一份行業報告，70%的企業使用者希望OCR能夠提供更高的結構保真度。這意味著模型必須在保持表單邏輯的同時，掌握精準的OCR識別。

為什麼選擇這張圖片進行測試？

選擇測試文件並非易事。IRS 5500-EZ 表格包含複雜且敏感的資料欄位。它包含手寫和印刷元素，佈局緊湊，因此非常適合進行原始OCR測試。虛線和各種欄位迫使模型展現出卓越的佈局理解能力。準確的欄位提取是AI文件正確處理的必要條件。稅務表格上的錯誤會對業務產生清晰、可量化的影響。這份表格為文件分析的真正能力提供了嚴格的測試。

實際測試執行與分析

我們透過各模型的公開 API 或 Web 平臺介面訪問了它們。對於每個模型，我們都貼上了相同的 OCR 提示資訊並提交了 IRS 表格影像。這種方法確保我們測試的是核心光學字元識別引擎。提示資訊要求在保留原始結構的同時，精確提取文字。

OCR 提示詞：“Perform OCR (Optical Character Recognition) on the provided image or PDF document to extract all visible text exactly as it appears in the document. 

# Steps

1. **Input Handling**: Ensure the input is a supported image format (e.g., JPEG, PNG) or a PDF document.

2. **Image Processing**: If necessary, pre-process the image for better OCR results. This might include adjusting brightness, contrast, or converting to grayscale.

3. **OCR Execution**: Use an OCR tool or library to scan the document and extract the text. Ensure the tool is configured to preserve the text formatting as closely as possible.

4. **Text Extraction**: Retrieve the text from the OCR output, ensuring all text is captured as it appears in the document, including punctuation, capitalization, and line breaks.

# Output Format

– Provide the extracted text in a plain text format.

# Example

– Input: An image of a printed page with text.

– Output: “This is the extracted text, maintaining punctuation and line breaks accurately as seen in the source image.”

# Notes

– Ensure that text extraction maintains the original document’s structure and formatting.”

Form 5500-EZ (2023)

DeepSeek 的響應速度很快，僅需 4-6 秒即可返回結果。然而，其在文件分析方面的表現卻不盡如人意。該模型漏掉了文件標題中的幾個重要欄位，並且對財務表格的佈局理解也存在偏差。關鍵欄位存在轉錄錯誤，例如將“ACME Corp Software”識別為“Aone Corp Software”。如此高的錯誤率意味著 DeepSeek 的輸出結果需要大量的人工校正。在這個應用中，速度並不能彌補嚴重的資料丟失。

Qwen-3 VL 提供了最佳的字元級 OCR 輸出。它展現了出色的結構保真度，證明了其強大的佈局理解能力。它能夠識別諸如覈取方塊標記之類的細微之處。然而，系統在處理過程中出現了超時現象。在嘗試完成提取時，系統開始輸出無限個點。這種嚴重的速度故障使得該模型目前無法用於任何高容量 AI 文件處理流程。沒有低延遲，高精度毫無意義。

在這項全面的對比測試中，Mistral OCR 的響應速度最快，僅需 3-4 秒即可完成全部提取工作。其輸出格式清晰且結構良好，對所有手寫和印刷欄位的識別準確率都非常高。更重要的是，其佈局理解功能使得提取的資料易於使用。Mistral 成功提供了最完整、最實用的最終結構。此外，該模型還成功推斷出第 6c 行的“淨計劃資產總額”，這充分展現了其超越原始文字的強大內部一致性。

建立穩健的OCR模型對比指標

最終點評：DeepSeek OCR vs Qwen-3 VL vs Mistral OCR

實際應用需要在準確性和速度之間做出權衡。在現實世界中，理論上的高效能並不足以確保成功。實際測試清楚地表明瞭這一點。

Mistral OCR 在這項特定的文件分析任務中提供了最佳平衡：它兼具高準確性、出色的佈局理解能力和最快的處理速度。輸出計算值方面的小問題可以忽略不計，因為它的整體實用性很高。

Qwen-3 VL 的識別能力很強，但無法透過延遲測試。DeepSeek OCR 速度很快，但其光學字元識別效能較差，不適用於複雜表單。為了實現穩健的 AI 文件處理，應選擇速度和結構保真度都經過驗證的架構。行業趨勢正在從單純追求蠻力準確轉向快速、準確且具有上下文感知能力的提取。

小結

現代 OCR 的選擇最終取決於準確性和實際生產速度之間的平衡。基準測試分數固然重要，但實際可靠性更為關鍵。 Mistral 的優勢在於其快速的識別速度和強大的佈局理解能力，使其成為嚴肅文件處理工作的最佳選擇。DeepSeek 速度很快，但 OCR 質量穩定性欠佳；Qwen-3 VL 讀取效果不錯，但延遲較高，因此不適合企業級應用。當延遲會中斷工作流程時，可靠的速度和結構保真度比理論上的準確性更為重要。選擇一款在實際應用中表現可靠的工具。
