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-1.5 Best 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
