GPT 5
PremiumOpenAI's powerful general-purpose frontier model.
Strong performance across reasoning, coding, math, and instruction following with a 1M-token context window.
▼
GPT 5 by OpenAI has a Capability Index of 81.8, making it comparable to the field average. It ranks #20 out of 92 models on the idapt capability leaderboard. It resolves 74% of SWE-bench Verified coding tasks. GPT 5 is somewhat expensive at $1.25/M tokens input and $10.00/M tokens output. Cached input reads are priced at $0.13/M tokens, making repeated context cheaper. The model supports vision/image input, extended reasoning, a 400K context window.
