Key Takeaways
- GPT-5.x is the current frontier series; GPT-5.1 is best for coding/agentic work
- o-series (o3, o4-mini) are reasoning models for complex tasks — succeeded by GPT-5
- Realtime/Audio has its own dedicated model family separate from Chat Completions
- Diarization (speaker identification) is a distinct model:
gpt-4o-transcribe-diarize - Embedding: prefer
text-embedding-3-largefor accuracy,text-embedding-3-smallfor cost - Moderation: use
omni-moderation-latest— handles both text and images - computer-use-preview is the specialized model for agentic computer control
- Many older models (o1-mini, gpt-4.5-preview, chatgpt-4o-latest) are now deprecated — avoid in new projects
