Core parameters and statistics
Specific technical parameters (such as model size, context length, supported file formats, input and output restrictions, etc.) are subject to the official product page. It is recommended that users verify the latest technical specifications and system requirements before choosing to ensure that they match their own usage scenarios.
User and market recognition
ChatGPT has become the core product entrance of OpenAI. The OpenAI official website navigation also provides entrances to ChatGPT, Business, Enterprise, Education, download API platform, developer documentation, customer cases, etc., indicating that it has expanded from a single conversation product to a comprehensive AI work platform for individuals, teams, enterprises, and educational organizations.
Individual User

For market data such as user scale and number of companies, if OpenAI does not continuously disclose it publicly, it is recommended to treat it as "undisclosed" and not quote unverified second-hand statistics.
Cost advantage
OpenAI's cost advantage comes primarily from model layering, batch processing, cached inputs, smaller models, and service tier selection. For developers, API costs are usually determined by input tokens, output tokens, cached inputs, tool calls, and batch processing strategies; for ChatGPT product users, costs are determined by package permissions such as Free, Plus, Pro, Business, Enterprise, and Education.
C client/personal
- The Free tier is suitable for lightweight experience, while paid tiers such as Plus/Pro provide higher usage limits, stronger models or more complete tool capabilities; the package benefits of different regions and account types are subject to the ChatGPT pricing page.
- Hidden costs mainly come from available regions, account compliance, whether files/data can be uploaded, and whether key conclusions require manual review.
Developer/API
- API side costs vary with models, input and output tokens, tool calls, batch processing, caching and priority services. Repeated long prompt RAG and batch processing scenarios should prioritize evaluating cached inputs with the Batch API.
- If the task only requires classification, extraction, summary or batch light reasoning, give priority to testing lower-cost models; if the task involves complex planning, code and high-value analysis, use stronger models.
Enterprise/Privatization
- Business, Enterprise, Education and API Enterprise contracts focus not just on price, but also on data control, auditing, permissions, compliance SLAs and purchasing terms.
- Enterprise pricing, data retention and advanced governance terms usually need to be confirmed in conjunction with the official page and commercial contract.
Web Search
- Enter price: US$10.00 / 1,000 calls
- Cached input prices: N/A
- Output price: Search content token is free -Official positioning: retrieve the latest information from the web
GPT-Realtime-Translate
- Enter price: US$0.034/minute
- Cached input prices: N/A
- Output price: N/A -Official positioning: real-time voice translation
GPT-Realtime-Whisper
- Enter price: US$0.017/minute
- Cached input prices: N/A
- Output price: N/A -Official positioning: streaming speech to text
Cost strategy recommendations: Use the flagship model for complex tasks, and prioritize the mini model, cached input, and Batch API for daily high-frequency tasks. Priority processing services can be evaluated for production-critical links, and elastic processing can be evaluated for low-priority tasks.
Main functions
- Universal dialogue: supports Q&A, explanation, organization, reasoning and multiple rounds of contextual communication.
- Content Creation: Can be used for article outlines, summaries, emails, scripts, reports and marketing copy.
- Programming assistance: covering code generation, debugging, refactoring, test cases and technical documentation.
- Multi-modal capabilities: Combining GPT with real-time/image models to support text, voice, and image-related tasks.
- Web search: Get the latest information through the official web search tool and support answer citations.
- Document and knowledge processing: suitable for long document summarization, table analysis, knowledge base Q&A and corporate information organization.
- API and tool calls: Build production-grade workflows through the OpenAI API, Playground, batch, container and service layers.
Model and version evolution
Continuous iterative updates, the latest version introduces performance optimization and new features. Historical version information can be viewed on the official release page. There is no complete public version evolution timeline yet. It is recommended to pay attention to the official announcement to understand the rhythm of feature updates.
Technical advantages
The advantage of OpenAI lies not only in a single model, but in the combination of models, product APIs, tools and corporate governance capabilities.
Model layering: The flagship model mini model, real-time model and image model serve complex reasoning, high-frequency and low-cost, voice interaction and image tasks respectively.
Tool Ecosystem: Web search, containers, batch processing, priority processing and elastic processing allow developers to make trade-offs between accuracy, cost, throughput and stability.
Product Maturity: ChatGPT provides ready-to-use experience for individuals and teams, the API platform provides programmability capabilities for developers, and Enterprise/Education provides governance paths for organizations.
Cost control mechanism: Caching the input Batch API and model layering can significantly optimize the cost of repetitive tasks and batch tasks.

Compare with similar tools
The advantages of ChatGPT lie in product maturity, model level richness, and API ecological integrity; however, in terms of Chinese localization, domestic access convenience, and low-price strategy, it needs to be differentiated from similar products at home and abroad.
ChatGPT
- Main advantages: OpenAI has a mature ecosystem, complete models, tool APIs, and enterprise solutions; strong general capabilities
- Relative restrictions: Registration/access is limited in unsupported regions such as mainland China; high-end functions depend on package or API costs
- More suitable users: global users, developers, multinational teams, companies that value ecological maturity
Claude
- Main advantages: Outstanding performance in long text understanding, writing and safety alignment
- Relative limitations: The available regions and Chinese ecology are not as good as domestic tools; some advanced capabilities are more expensive
- Better suited for: Research, long document, legal/compliance, professional writing users
Gemini
- Main advantages: Close integration with Google Search Workspace and Android ecosystem
- Relative limitations: Functional opening is inconsistent in different regions; corporate procurement relies on the Google ecosystem
- More suitable users: Google Workspace users, search/office ecosystem users
DeepSeek
- Main advantages: open source model, Chinese inference API cost and more flexible local deployment options
- Relative limitations: The product ecosystem and international business tool chain are not as complete as OpenAI
- More suitable users: Chinese developers, cost-sensitive enterprises, privatization/open source model users
Bean bag
- Main advantages: Chinese experience, local content ecology and domestic access convenience
- Relative restrictions: International API ecology and enterprise-level governance capabilities need to be evaluated based on official opening conditions
- More suitable users: individual users in mainland China, Chinese content teams, and Byte ecosystem users
Selection suggestions: If the team needs global products, stable APIs, and rich tool chains, ChatGPT/OpenAI API is the priority; if it is mainly for Chinese users in mainland China, domestically available solutions such as DeepSeek, Doubao Kimi, and Tongyi should also be evaluated to avoid binding core processes to services that cannot be stably accessed.
