GPT-5.4 vs GPT-5.4 Pro
Updated October 20, 2026. Rank says GPT-5.4 Pro is ahead. Price, access, and your workload can each overturn that. Public scores include evidence status and uncertainty. This is a same-family comparison, so migration details appear when the source data supports them.

Decision reading
GPT-5.4 Pro has the higher public point estimate, 68.69 versus 66.73. Their conditional score ranges overlap. These ranges do not establish rank confidence. 7 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

Category results, on a stated basis
Each row shows the public-lane category score for both models: the BenchAlign v5.8 lane for agentic, coding, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, and knowledge denominators (BenchAlign v5.8) differ from the provisional-lane categories. Unranked scores sit on the provisional lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

Questions
Which is better, GPT-5.4 or GPT-5.4 Pro?
GPT-5.4 Pro has the higher public point estimate, 68.69 versus 66.73. Their conditional score ranges overlap. These ranges do not establish rank confidence. The page therefore keeps the decision tied to the specific documented workload.
Which is better for coding, GPT-5.4 or GPT-5.4 Pro?
GPT-5.4 Pro is not ranked on the public lane for coding, so no winner is named for coding.
Which is better for agentic tasks, GPT-5.4 or GPT-5.4 Pro?
GPT-5.4 Pro is not ranked on the public lane for agentic tasks, so no winner is named for agentic tasks.
Which costs less, GPT-5.4 or GPT-5.4 Pro?
For the stated presets, chat costs $0.01 on GPT-5.4 and $0.12 on GPT-5.4 Pro; repository review costs $0.17 and $2.04; the cache-heavy agent loop costs $0.25 and $8.40. GPT-5.4 Pro has no published cached-input rate, so cached tokens use its listed input rate.
Which has the larger context window, GPT-5.4 or GPT-5.4 Pro?
Both models list the same context window, 1.05M.
