Claude 3 appears to be a strong contender in the AI landscape, particularly excelling in handling complex reasoning tasks, providing robust data privacy, and offering a subscription-based model with a free tier. ChatGPT has a slight edge in integration with other platforms. The choice between the two depends on the specific needs and priorities of the user.
| Attribute | chatgpt | claude |
|---|---|---|
| Context window size (token limit) | GPT-3.5: 4,096 tokens, later expanded to 8,192 tokens with GPT-3.5-Turbo. GPT-4: Initially 8,192 tokens, later increased to 128,000 tokens. Output capped at 4,096 tokens. GPT-4o and GPT-4o mini: 128,000 tokens, with output capped at 16,384 tokens. Earlier versions: Some earlier versions had a context window of 1024 tokens. | Claude models have different context window sizes. Claude 2 had 100,000 tokens. Claude 3 models, including Haiku, Sonnet, and Opus, feature a 200,000 token context window. Claude 3.7 Sonnet has a context window of up to 128,000 tokens and supports a maximum output of 64,000 tokens. |
| Factual accuracy and hallucination rate | General knowledge: GPT-4o scores around 88.8% on general knowledge tests. Real-world factual questions: Accuracy can range between 47% and 62%, depending on the prompt and model. Hallucination rates: Can vary significantly. GPT-3.5: Hallucination rates around 39.6% in some studies. GPT-4: Lower hallucination rates compared to GPT-3.5, but still present, around 28.6% in some studies. GPT-4o: Accuracy rate of 6.35% in some studies. ChatGPT is wrong about 1 out of every 3 times on factual questions, even with its newest models. | Claude 3 Opus outperforms previous versions in accuracy. Claude is designed to acknowledge its limitations and provide transparent responses rather than fabricating information. Claude models are reported to have very low hallucination rates. |
| Pricing model (pay-per-use, subscription, etc.) | Pay-per-use. You pay for the tokens you use. | Claude offers a free plan with limited access to the Claude 3 Sonnet model. Claude Pro: $20/month, provides access to top-tier models and enhanced capabilities. Claude Team: $25/user/month (5+ users), includes Pro features plus team-oriented tools. Claude Enterprise: Custom pricing, offers comprehensive access, enhanced security, and advanced integration. Claude API offers standard and pro pricing models, with costs varying based on model selection, usage volume, and subscription plan. Claude 3.5 Sonnet generally has higher pricing tiers than GPT-4o Mini. |
| Availability of API access | Yes, OpenAI provides an API to integrate ChatGPT into applications. | Claude provides API access for integration into applications. To use Claude 3.5 Sonnet in your application, you'll need to connect to the Anthropic API. Steps to access the API: Register and get API access, obtain your API key, set up your development environment, and test the connection. |
| Customization options (fine-tuning, prompt engineering) | Fine-tuning and prompt engineering. | Claude can be customized through prompt engineering. The "think" tool creates dedicated space for structured thinking during complex tasks. |
| Speed of response generation (latency) | Expect a response time of 1 to 10 seconds, depending on model complexity, input size, server load, and network conditions. Factors influencing latency: OpenAI API processing time, query length and complexity, plugin parameters, internet connection, and API version used. | Claude 3 Haiku is designed for instant responses. Claude 3 Sonnet balances speed with reasoning abilities. Claude 3 Opus emphasizes accuracy over speed. Claude 3.5 Haiku demonstrates slightly faster performance than Claude 3.5 Sonnet. Factors affecting Claude API latency: network transmission time, server processing time, model complexity, input token count, and output generation time. |
| Support for different languages | Officially supports 58 languages. Demonstrates some level of ability in almost twice as many natural languages. Performs best in English due to the larger dataset. | Claude supports major global languages, including Spanish, Japanese, French, Portuguese, and German. It also supports Mandarin Chinese, Italian, Russian, Arabic, Hindi, and Korean. Claude excels at tasks across multiple languages, maintaining strong cross-lingual performance relative to English. |
| Safety measures and content moderation policies | Specific safety measures are in place to prevent the model from generating harmful or inappropriate content. | Claude includes advanced safety filters to prevent the generation of harmful content. It adheres to safety principles drawn from ethical and human rights documents. Claude uses a "Constitutional AI" framework, including safety principles from the Universal Declaration of Human Rights and industry conduct codes. |
| Integration with other platforms and services | Can be integrated with any app that offers API access. | Claude can be integrated with other applications and services. Integrations are available for services like Atlassian's Jira and Confluence, Zapier, Cloudflare, Intercom, Asana, Square, Sentry, PayPal, Linear, and Plaid. Claude MCP (Model Context Protocol) is an open standard enabling AI systems to connect with external tools and real-time data sources. |
| Data privacy and security policies | Information on specific data privacy and security policies should be checked on the OpenAI website. | Claude is designed with a strong emphasis on data privacy and security. User data is retained for a maximum of 90 days for system functionality and user convenience, after which it is automatically deleted. Anthropic commits to not using data from user interactions to train the AI models unless explicit consent is provided. Claude adheres to rigorous privacy policies and complies with data protection regulations. Claude utilizes strong encryption algorithms such as AES, RSA, and Triple DES to protect data both at rest and in transit. |
| Ability to handle complex reasoning tasks | Performance varies based on the complexity of the task. Hallucination rates increase with complex reasoning tasks. | Claude 3 Opus is designed to handle the most complex and demanding tasks, emphasizing depth and precision. Claude 3.7 Sonnet introduces an innovative feature called |
