OpenAI

OpenAI's newest flagship model. Improved reasoning, instruction following, and coding over GPT-4o.

OpenAI's most capable multimodal model. Excellent for complex reasoning, coding, and creative tasks.

OpenAI's GPT-4o with native image input. Handles text and images in a single context, 128k window, strong on chart reading, document QA, screenshots and visual reasoning.

OpenAI's unified flagship combining GPT and o-series reasoning into one model. 1M context, multimodal, top SWE-Bench Pro and OSWorld scores.

OpenAI's efficient mid-tier model. 2x faster than its predecessor, 400k context, approaches GPT-5.4 quality on SWE-Bench Pro at a fraction of the cost.

OpenAI's current flagship chat model (released April 2026). Strongest general reasoning, coding and tool use in the GPT-5 line, with vision input and a large context window.

OpenAI's reasoning model optimized for STEM tasks, coding, and math. Uses chain-of-thought reasoning.

OpenAI's second-generation Sora video model. Realistic motion, improved physics, audio support.

OpenAI's highest-quality embedding model. Returns 3072-dim vectors by default and supports reducing dimensions via the dimensions parameter. Outperforms text-embedding-3-small and the older ada-002 on MTEB and multilingual MIRACL retrieval benchmarks, for cases where accuracy matters more than cost.

OpenAI's small, low-cost embedding model. Returns 1536-dim vectors by default and supports shortening output dimensions via the dimensions parameter without retraining. Replaced text-embedding-ada-002 with better retrieval quality at a fraction of the price, and is the default choice for general-purpose semantic search and RAG.

OpenAI video generation model. Create realistic and imaginative videos from text prompts up to 20 seconds.

OpenAI's Whisper model. State-of-the-art speech recognition supporting 99+ languages.

OpenAI's distilled Whisper Large v3. ~216x realtime, 99+ languages, MIT-licensed weights.

OpenAI's latest image generation model. Excellent at following complex prompts with high fidelity.

Small, fast, and affordable model for lightweight tasks. Great balance of speed and capability.

OpenAI's small multimodal model with image input. Much cheaper than GPT-4o, 128k context, good for high-volume captioning, OCR-style reads, tagging and screenshot understanding.

Smaller, faster, cheaper member of OpenAI's GPT-5 family. Tuned for high-throughput chat, classification and extraction where the full flagship is overkill.

OpenAI GPT-5.1 chat model (November 2025). An earlier GPT-5 point release kept available for compatibility. Good general-purpose reasoning and coding.

OpenAI's smallest and cheapest GPT-5.4 variant. Built for high-volume classification, extraction and coding subagents at edge-grade latency.

OpenAI's o3 reasoning model. Spends compute on a private chain of thought before answering, strong at math, science and hard coding problems that benefit from deliberate reasoning.

OpenAI's o4-mini reasoning model. A cost-efficient reasoning model that trades some depth for much lower price and latency, good for high-volume math and code tasks.

OpenAI's text-to-speech model. Six built-in voices with natural intonation.

OpenAI's high-definition TTS model. Better quality for production use cases.
