OpenAI
OpenAI is an AI research and deployment company focused on building artificial general intelligence (AGI) that is safe and beneficial for humanity. It develops and operates frontier large language models including the GPT series, multimodal models, image generators, and agentic products, offered via its consumer ChatGPT platform and developer API. OpenAI has expanded its portfolio to include open-weight models (GPT-OSS), video generation (Sora), and autonomous agent capabilities.

Products
GPT-5.4 is OpenAI's frontier large language model featuring advanced reasoning and extended long-context capabilities. It offers tiered pricing at $2.50/$15 per million input/output tokens for standard usage, with rates doubling to $5/$22.50 per million tokens above the 272K token threshold. Designed for enterprise and developer use cases requiring large context windows and high-throughput inference.
general-purposeChatGPT is OpenAI's flagship conversational AI assistant, layered on top of their GPT and o-series models to deliver capabilities far beyond raw model access — including web browsing, code execution (Advanced Data Analysis), image generation via DALL-E, file and document analysis, memory, persistent Projects, and a GPT Store for specialised agents. Launched in November 2022, it triggered a mainstream AI adoption wave and remains the most widely used AI assistant globally. It supports agentic workflows through tool use, Operator-style task execution, and integrations, making it a true agent platform rather than just a model interface.
general-purposeOpenAI Codex is a cloud-based software engineering agent capable of autonomously completing coding tasks such as writing features, fixing bugs, running tests, and navigating codebases — operating in isolated sandboxes in parallel. It is available as both a cloud agent integrated into ChatGPT and an open-source CLI tool (Codex CLI), competing directly with Claude Code, Devin, and similar agentic coding products. The agent is powered by codex-1, a model fine-tuned for agentic software engineering tasks.
codingCodex CLI is OpenAI's open-source command-line coding agent that runs directly in the terminal, capable of reading and writing files, executing shell commands, and performing multi-step coding tasks autonomously. It supports multiple approval modes (suggest, auto-edit, full-auto) and acts as an MCP client, integrating with a growing ecosystem of tools and servers. Originally launched in April 2025, it received a major model upgrade to GPT-5.2-Codex in December 2025 and expanded to a desktop app in February 2026.
