Use this when
Complex professional tasks requiring nuanced reasoning, strong writing quality, and reliable instruction-following across long conversations.
Skip this if
You need to process documents exceeding 128K tokens, require native image generation, or are running high-throughput workloads where cost-per-token is a primary constraint.

Speed
Balanced
Pricing is asymmetric — input is relatively affordable at $1.25/1M but output at $10/1M can accumulate quickly in agentic or verbose-output workflows. Cached input pricing may apply through the OpenAI API. Not to be confused with GPT-5 reasoning variants (o-series) which use chain-of-thought and have separate pricing.
Significantly improved instruction-following and task decomposition over GPT-4o
Strong coding performance competitive with Claude Sonnet 4.6 on real-world benchmarks
Better calibration and reduced hallucination rate compared to its predecessors
Competent multimodal understanding for image analysis and mixed-media tasks
Weaknesses
128K context window falls short of Gemini 3.1 Pro's 1M+ token window for large document tasks
Output cost of $10/1M tokens makes high-volume production pipelines expensive compared to GPT-4o Mini or Haiku equivalents
No native image generation; image tasks require routing to separate DALL-E or other endpoints

OpenAI: GPT-5
GPT-5 is OpenAI's flagship multimodal model, superseding GPT-4o with significantly improved reasoning, instruction-following, and knowledge breadth. It handles text, images, and complex multi-step tasks with state-of-the-art performance across most benchmarks.
Verdict
OpenAI's best general-purpose model — a strong flagship pick that punches above its price on input costs while delivering top-tier reasoning and multimodal capability.

Context
400k tokens
Pricing is asymmetric: cheap on input ($1.25/1M) but expensive on output ($10/1M), so it favors read-heavy or summarization tasks over verbose generation. The 400K context window is one of the largest available at this price tier. Supersedes GPT-4o, which remains available at lower cost for lighter workloads.
