Overview

Freshness note: Model capabilities, limits, and pricing can change quickly. This profile is a point-in-time snapshot last verified on February 26, 2026.

GPT-5 represents the initial release entry for the GPT-5 generation. In current usage, OpenAI’s lineup has moved to newer GPT-5.3 and GPT-5.4 variants for the latest recommended routes.

Capabilities

GPT-5 established the baseline for the generation with strong reasoning, coding, structured output behavior, and long-context operation.

Technical Details

Published limits for the GPT-5 generation baseline are 400K context and 128K maximum output, with support for modern tool-use workflows.

Pricing & Access

Historical public API pricing for this tier was:

  • Input: $1.25 per 1M tokens
  • Output: $10.00 per 1M tokens

Use current OpenAI model docs for active routing recommendations.

Best Use Cases

This entry is best treated as historical context for the GPT-5 generation baseline. For new deployments, prefer GPT-5.3 for everyday work or GPT-5.4 for harder professional workflows.

Comparisons

  • GPT-5.4 (OpenAI): Current higher-capability successor in this lineup snapshot.
  • GPT-5.3 (OpenAI): Newer fast workhorse variant for general production use.
  • GPT-5 mini (OpenAI): Lower-cost route for high-volume workloads.
  • Claude Sonnet 4.6 (Anthropic): Alternative default model for broad production tasks.
