كتبت شروق عارف
مع التطور الهائل في تقنيات الذكاء الاصطناعي أصبح هذا المجال ساحة تنافس شرسة خاصة بين الولايات المتحدة والصين لم تعد الدول تنظر إلى الذكاء الاصطناعي كأداة مساعدة فقط بل كقوة عظيمة تحدد ملامح المستقبل وتمنح الأفضلية لمن يتفوق فيه على الساحة العالمية فما هي أبرز التطورات الأخيرة في مجال الذكاء الاصطناعي بين الولايات المتحدة والصين؟
في البداية، تصدرت الولايات المتحدة المشهد عبر نظام ChatGPT الذي طورته شركة OpenAI والذي أحدث ثورة في عالم الذكاء الاصطناعي التفاعلي. لكن الصين لم تلبث أن ردت بقوة من خلال نظام DeepSeek V3، الذي سرعان ما تصدر قائمة التنزيلات في الولايات المتحدة، متفوق على ChatGPT في بعض الجوانب مما أعاد إشعال المنافسة مجددا
Deep Seek منافس قوي لكنه ما زال تحت التجربة
يرى الدكتور إبراهيم عبد الله أستاذ تكنولوجيا المعلومات في المعاهد العليا للدراسات النوعية إن منصة DeepSeek تقدم خدمات قوية ومجانية قد تدفع البعض لتفضيلها على ChatGPT لكنها لا تزال تحت التجربة، ولا يمكن الاعتماد عليها كليًا في الوقت الحالي وأضاف أن دعم البرمجيات مفتوحة المصدر يمثل فرصة مهمة للتطوير والابتكار لكن استخدامها يجب أن يتم بحذر وذلك لتجنب أي تهديدات أمنية محتمل
أبرز الاختلافات بين ChatGPT وDeep Seek
بحسب ما ورد في موقع click up وما ذكره ماركو ممدوح يعتبر Deep Seek نموذج ذكي من تطوير شركة صينية الذي أسسها رجل الأعمال لينج وينفينج ويعتمد على أكثر من 37 مليار معلومة وذلك يمنحه دقة عالية في الإجابة يتميز بأنه مجاني بالكامل ويدعم أكثر من 95 لغة من بينها العربية حيث يظهر اداء قوي قد يتفوق علي ChatGPT في بعض الأحيان
أما ChatGPT فهو من تطوير شركة OpenAI الأمريكية وانطلق في نوفمبر 2022 بدعم من شركة مايكروسوفت يشتهر بقدرته على التفاعل بلغة طبيعي وتميزه في الكتابة الإبداعية وصناعة الصور وتحويل النصوص إلى صوت. ومع ذلك فإن نسخته الأقوى GPT-4 تتطلب اشتراك مدفوع
أيهما يتفوق
رغم أن ChatGPT يتميز بالتفاعل الواسع والإبداع في اللغة إلا أن Deep Seek يتفوق عليه في تحليل البيانات، التفكير المنطقي والرياضيات بالإضافة إلى دعمه القوي للبرمجيات مفتوحة المصدر كما يمنح المستخدمين تحكم كامل في بياناتهم في مقابل بيئة مغلقة نسبيا في ChatGPT
لكن Deep Seek لم يسلم من الانتقادات خاصة بعد كشف تقارير عن ثغرات أمنية خطيرة، منها تعطيل أنظمة تشفير على أجهزة iPhone واستخدام تقنيات قديمة قالت هيئة حماية البيانات الإيطالية أنها حظرت نموذج DeepSeek من استخدامه كما حذّرت دول مثل تايوان من استخدامه خوفًا من تسريب بيانات حساسة في المقابل يواجه ChatGPT تحديات تتعلق بالدقة والتحيز السياسي أحيانا وعدم تقديمه دائما معلومات مكتملة أو صحيحة بالإضافة إلى إمكانية تجاوزه لقيود الأمان وذلك من خلال إعادة صياغة الأسئلة
Deep Seek ينافس بقوة و لكن ChatGPTيتفوق في الأداء
من جانبه يرى عمر عاطف خبير التكنولوجيا أن الذكاء الاصطناعي أصبح منافس حقيقي في عدة مجالات سواء في كتابة المحتوى أو تحليل البيانات أو حتى التعليم، ومع ظهور أدوات مثل DeepSeek أصبح المستخدم أمام خيارات متعددة تتيح له تجربة تقنيات متقدمة بشكل مجاني وأشار إلى أن رغم قوة هذه الأدوات فإن ChatGPT لا يزال متفوق من حيث الأداء ودقة النتائج خاصة في النسخ المدفوعة التي توفر ميزات أوسع لكن المنافسة تدفع الجميع للتطوير باستمرار
ولكن يبقى الرهان الحقيقي بين عمالقة الذكاء الاصطناعي على من يستطيع تلبية احتياجات المستخدمين بذكاء وأمان وأفضل الإمكانيات في ان واحد
