GPT-5.3-Codex is optimized for agentic coding tasks in Codex or similar environments. GPT-5.3-Codex supports low, medium, high, and xhigh reasoning effort settings.

GPT-5.2-Codex is an upgraded version of GPT-5.2 optimized for agentic coding tasks in Codex or similar environments. GPT-5.2-Codex supports low, medium, high, and xhigh reasoning effort settings.

gpt-5.2-pro is the highest-capability, production-oriented member of OpenAI’s GPT-5.2 family, exposed through the Responses API for workloads that demand maximal fidelity, multi-step reasoning, extensive tool use and the largest context/throughput budgets OpenAI offers.

GPT-5.1-Codex-Max is OpenAI’s purpose-built agentic coding model in the GPT-5.1 family, optimized to execute long-running software engineering workflows (refactors, multi-hour agent loops, terminal automation, test runs and code review) with higher reliability and token efficiency than its predecessors.

GPT-5.1 Chat is an instruction-tuned conversational language model for general-purpose chat, reasoning, and writing. It supports multi-turn dialogue, summarization, drafting, knowledge-base QA, and lightweight code assistance for in-app assistants, support automation, and workflow copilots. Technical highlights include chat-optimized alignment, controllable and structured outputs, and integration paths for tool invocation and retrieval workflows when available.

GPT-5.1 is a general-purpose instruction-tuned language model focused on text generation and reasoning across product workflows. It supports multi-turn dialogue, structured output formatting, and code-oriented tasks such as drafting, refactoring, and explanation. Typical uses include chat assistants, retrieval-augmented QA, data transformation, and agent-style automation with tools or APIs when supported. Technical highlights include text-centric modality, instruction following, JSON-style outputs, and compatibility with function calling in common orchestration frameworks.

Cost-optimized version of GPT Image 1. It is a native Multimodal language model that accepts both text and image input and generates image output.

GPT-5 Nano is an artificial intelligence model provided by OpenAI.

GPT-5 mini is OpenAI’s cost- and latency-optimized member of the GPT-5 family, intended to deliver much of GPT-5’s multimodal and instruction-following strengths at substantially lower cost for large-scale production use. It targets environments where throughput, predictable per-token pricing, and fast responses are the primary constraints while still providing strong general-purpose capabilities.
