Latest model guide

This file is a curated helper. Every recommendation here must be verified against current OpenAI docs before it is repeated to a user.

Current model map

Model ID	Use for
`gpt-5.5`	Latest/default text and reasoning model for most new apps, including coding and tool-heavy workflows
`gpt-5.5-pro`	Maximum reasoning or quality when latency and cost matter less
`gpt-5.4`	Previous default text and reasoning model; use for existing GPT-5.4 integrations
`gpt-5.4-mini`	Lower-cost testing and lighter production workflows
`gpt-5.4-nano`	High-throughput simple tasks and classification
`gpt-5.5`	Explicit no-reasoning text path via `reasoning.effort: none`
`gpt-4.1-mini`	Cheaper no-reasoning text
`gpt-4.1-nano`	Fastest and cheapest no-reasoning text
`gpt-5.3-codex`	Agentic coding, code editing, and tool-heavy coding workflows
`gpt-5.1-codex-mini`	Cheaper coding workflows
`gpt-image-2`	Best image generation and edit quality
`gpt-image-1.5`	Less expensive image generation and edit quality
`gpt-image-1-mini`	Cost-optimized image generation
`gpt-4o-mini-tts`	Text-to-speech
`gpt-4o-mini-transcribe`	Speech-to-text, fast and cost-efficient
`gpt-realtime-1.5`	Realtime voice and multimodal sessions
`gpt-realtime-mini`	Cheaper realtime sessions
`gpt-audio`	Chat Completions audio input and output
`gpt-audio-mini`	Cheaper Chat Completions audio workflows
`sora-2`	Faster iteration and draft video generation
`sora-2-pro`	Higher-quality production video
`omni-moderation-latest`	Text and image moderation
`text-embedding-3-large`	Higher-quality retrieval embeddings; default in this skill because no best-specific row exists
`text-embedding-3-small`	Lower-cost embeddings
