GPT Image 1 (legacy)GPT Image 1 moved to tokenized pricing ($10/$40 per 1M tokens). We show approximate price per 1024×1024 high-quality image. A new 'image-tokens' kind is coming in a future sprint.
GPT-4.1 mini (legacy)1M context at low price. Replaceable by GPT-5.6 Luna or Gemini 2.5 Flash-Lite.
GPT-4o mini TTSLatest generation: prompt-controlled voice (instructions for tone, emotion, pace). 7 voices.
GPT-5 (legacy)Original GPT-5. Kept for backward compat; recommend migrating to 5.1 or 5.4-mini depending on use case.
GPT-5.1Refinement of GPT-5 at the same price. Better instruction following and tool handling.
GPT-5.4 miniEconomic variant of 5.4. Sub-dollar per 1M input tokens, good balance for chatbots.
