Choose DeepSeek if you're cost-conscious, building high-volume applications, need open-source model flexibility, or prioritize faster response times for routine coding and text tasks.","keyDifferences":[{"label":"API Cost per 1M Input Tokens","winner":"b","entityAValue":"$5.00 (GPT-4o)","entityBValue":"$0.14 (DeepSeek R1)"},{"label":"Reasoning Capability (AIME Score)","winner":"a","entityAValue":"96.4% (o1-preview)","entityBValue":"79.8% (R1)"},{"label":"Supported Languages","winner":"a","entityAValue":"95+ languages","entityBValue":"30+ languages"},{"label":"Model Architecture","winner":"b","entityAValue":"Proprietary (closed-source)","entityBValue":"Open-source weights available"},{"label":"Coding Benchmark (HumanEval)","winner":"a","entityAValue":"92% (GPT-4o)","entityBValue":"91.1% (DeepSeek R1)"}],"winner":{"slug":"chatgpt-gpt-4o","name":"ChatGPT (GPT-4o)"},"confidence":"high","entities":[{"name":"ChatGPT (GPT-4o)","slug":"chatgpt-gpt-4o","url":"https://www.aversusb.net/entity/chatgpt-gpt-4o","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/chatgpt-gpt-4o"},{"name":"DeepSeek (R1)","slug":"deepseek-r1","url":"https://www.aversusb.net/entity/deepseek-r1","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/deepseek-r1"}],"faqs":[{"question":"Which AI is better for cost-sensitive applications?","answer":"DeepSeek is dramatically more cost-effective at $0.14 per 1M tokens vs ChatGPT's $5, making it 3,571% cheaper. For a startup processing 1B tokens monthly, ChatGPT costs ~$5,000 while DeepSeek costs ~$140. However, ChatGPT may be more cost-effective for image-processing tasks since DeepSeek lacks vision capabilities."},{"question":"Can I self-host DeepSeek or ChatGPT?","answer":"DeepSeek offers open-source model weights, allowing local deployment, self-hosting, and fine-tuning on your hardware with no ongoing API costs. ChatGPT is closed-source and proprietary—you can only access it via paid API or web interface. For organizations requiring data privacy or offline capability, DeepSeek is the only option."},{"question":"Which is better for software development and coding tasks?","answer":"Both excel at coding: ChatGPT scores 92% on HumanEval while DeepSeek scores 91.1%, making them nearly equivalent. ChatGPT has a larger context window (128K vs 64K tokens), better for large codebases. DeepSeek is faster (1.4s vs 2.1s latency) and costs 97% less, making it superior for development teams building cost-effective CI/CD tools."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/chatgpt-vs-deepseek)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/chatgpt-vs-deepseek)), ChatGPT offers superior reasoning capabilities and broader language support through GPT-4o, while DeepSeek provides significantly lower costs (up to 95% cheaper) with competitive performance on coding","dateModified":"2026-07-06T22:27:43.765Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/chatgpt-vs-deepseek)","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/chatgpt-vs-deepseek)","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/chatgpt-vs-deepseek)","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/chatgpt-vs-deepseek)#claimreview","url":"https://www.aversusb.net/compare/chatgpt-vs-deepseek)","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"ChatGPT vs DeepSeek","reviewBody":"ChatGPT offers superior reasoning capabilities and broader language support through GPT-4o, while DeepSeek provides significantly lower costs (up to 95% cheaper) with competitive performance on coding and mathematical tasks through its open-source R1 model.","datePublished":"2026-07-06T22:27:43.673Z","dateModified":"2026-07-06T22:27:43.765Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/chatgpt-vs-deepseek)","url":"https://www.aversusb.net/compare/chatgpt-vs-deepseek)","name":"ChatGPT vs DeepSeek","inLanguage":"en-US"}}}
