Multimodal
gpt-5: gpt-5 provides deeper, richer reasoning for analytics and code generation capabilities.

Key Capabilities

  • Designed for logic-heavy and multi-step tasks.
  • Now supporting minimal reasoning, a new verbosity setting, and the "customs" tool for raw text output.
  • New "allowed tools" tool choice that enables you to specify multiple tools in the tool choice instead of just one
  • New "preamble" support, allowing the model to "think" before calling a tool. This is always enabled and controlled through prompting.
  • gpt-5 supports multimodal inputs, real-time streaming and full tool support for smarter, more dynamic user experiences

Safety

OpenAI has incorporated additional safety measures including new techniques to help the models refuse unsafe requests. These advancements make the o1 series some of the most robust models available. OpenAI measures safety is by testing how well models continue to follow its safety rules if a user tries to bypass them (known as "jailbreaking"). In OpenAI’s internal tests, GPT-4o scored 22 (on a scale of 0-100) while o1-preview model scored 84. You can read more about this in the OpenAI’s system card and research post .
