OpenAI

OpenAI is the AI research company behind ChatGPT, GPT-4o, DALL-E, and the Whisper speech recognition model. Through its API platform, OpenAI gives developers and businesses direct access to its frontier AI models to build their own products and workflows. The problem OpenAI solves for businesses is AI capability without AI research infrastructure. Building your own large language model requires hundreds of millions of dollars and years of research. OpenAI's API gives any company access to world-class AI in an afternoon, paying only for what they use. OpenAI serves two main audiences: end users who access its tools through ChatGPT, and developers and businesses who integrate its models via API into their own applications. Core features: GPT-4o API with multimodal capabilities — processes text, images, and audio in a single model. Assistants API for building AI agents with persistent memory, file search, and code execution. Fine-tuning capabilities to customize models on your own data for domain-specific applications. Pricing: ChatGPT Free and Plus ($20/month) for consumer access. API pricing is usage-based, starting at $0.15 per million input tokens for GPT-4o Mini and $2.50 per million for GPT-4o.
