GPT-3.5 Turbo

OpenAI's most capable and cost effective model in the GPT-3.5 family optimized for chat purposes, but also works well for traditional completions tasks.

GPT-3.5 Turbo Instruct

Similar capabilities as GPT-3 era models. Compatible with legacy Completions endpoint and not Chat Completions.

GPT-4 Turbo

gpt-4-turbo from OpenAI has broad general knowledge and domain expertise allowing it to follow complex instructions in natural language and solve difficult problems accurately. It has a knowledge cutoff of April 2023 and a 128,000 token context window.

GPT-4.1

GPT 4.1 is OpenAI's flagship model for complex tasks. It is well suited for problem solving across domains.

GPT-4.1 mini

GPT 4.1 mini provides a balance between intelligence, speed, and cost that makes it an attractive model for many use cases.

GPT-4.1 nano

GPT-4.1 nano is the fastest, most cost-effective GPT 4.1 model.

GPT-4o

GPT-4o from OpenAI has broad general knowledge and domain expertise allowing it to follow complex instructions in natural language and solve difficult problems accurately. It matches GPT-4 Turbo performance with a faster and cheaper API.

GPT-4o mini

GPT-4o mini from OpenAI is their most advanced and cost-efficient small model. It is multi-modal (accepting text or image inputs and outputting text) and has higher intelligence than gpt-3.5-turbo but is just as fast.

GPT-5

GPT-5 is OpenAI's flagship language model that excels at complex reasoning, broad real-world knowledge, code-intensive, and multi-step agentic tasks.

GPT-5-Codex

GPT-5-Codex is a version of GPT-5 optimized for agentic coding tasks in Codex or similar environments.

GPT-5 mini

GPT-5 mini is a cost optimized model that excels at reasoning/chat tasks. It offers an optimal balance between speed, cost, and capability.

GPT-5 nano

GPT-5 nano is a high throughput model that excels at simple instruction or classification tasks.

gpt-oss-120b

Extremely capable general-purpose LLM with strong, controllable reasoning capabilities

gpt-oss-20b

A compact, open-weight language model optimized for low-latency and resource-constrained environments, including local and edge deployments

o3

OpenAI's o3 is their most powerful reasoning model, setting new state-of-the-art benchmarks in coding, math, science, and visual perception. It excels at complex queries requiring multi-faceted analysis, with particular strength in analyzing images, charts, and graphics.

o3-mini

o3-mini is OpenAI's most recent small reasoning model, providing high intelligence at the same cost and latency targets of o1-mini.

o4-mini

OpenAI's o4-mini delivers fast, cost-efficient reasoning with exceptional performance for its size, particularly excelling in math (best-performing on AIME benchmarks), coding, and visual tasks.

text-embedding-3-large

OpenAI's most capable embedding model for both english and non-english tasks.

text-embedding-3-small

OpenAI's improved, more performant version of their ada embedding model.

text-embedding-ada-002

OpenAI's legacy text embedding model.
