GPT-4o review

GPT-4o is a large language model from OpenAI. Its strengths are well documented and widely supported; good speed for the quality. The main caution: superseded by newer OpenAI models for new projects. It has been superseded by a newer release, so compare it with current options before adopting it.

What it is

Legacy model, superseded by the GPT-6 family. GPT-4o is an earlier OpenAI multimodal model that handles text, images and audio in one system. It has been succeeded by newer OpenAI releases but remains a common reference point for speed and price-performance.

Key features

  • Text, image and audio input in one model
  • Fast responses suited to interactive use
  • Function calling and structured outputs
  • Broad third-party integration support

Pros

  • Well documented and widely supported
  • Good speed for the quality
  • Large library of tutorials and integrations

Cons

  • Superseded by newer OpenAI models for new projects
  • Weaker on complex multi-step reasoning than current flagships
  • Older knowledge cutoff

Pricing

GPT-4o is priced by usage rather than by seat: API: $2.50 in / $10 out per M tokens. That means cost scales with how much text you send and receive, so estimate your monthly volume before committing.

How to get started

Start with one real task you already do each week, give the model the full context, and compare the result with your usual output before changing your workflow. Keep sensitive client or patient data out of consumer chat apps unless your organization has approved the plan.

Alternatives to consider

  • ChatGPT (OpenAI, $20/mo): OpenAI's flagship conversational AI.
  • Claude (Anthropic, $20/mo): Anthropic's assistant, known for long-context reasoning, careful writing, and safety-aware outputs.
  • Claude Fable 5 (Anthropic, API: $10 in / $50 out per M tokens): Claude Fable 5 is a premium-tier Claude model priced above Opus, aimed at the hardest professional and technical work.
  • Claude Fable 5.1 (Anthropic, API: $10 in / $50 out per M tokens): Claude Fable 5.1 is Anthropic's premium generally available model, priced above Opus and built for the hardest reasoning, coding and analysis tasks.
  • Claude Haiku 4.5 (Anthropic, API: $1 in / $5 out per M tokens): Claude Haiku 4.5 is Anthropic's fast, low-cost model at $1 and $5 per million tokens.
