Our take

Written Aug 3, 2026

GPT-4o-mini is OpenAI's low-cost entry point to the GPT-4o family, handling text, images and files with a 128,000-token request limit. It offers broad benchmark coverage and consistent measured scores, though its parameter count remains undisclosed.

Who should pick it

Pick this for budget inference in the GPT-4o family with image and file input, or for coding tasks where it scores highest among its own benchmarks. Use it for long-context work up to 128,000 tokens. Skip it if you need strong maths performance, transparent parameter counts, or the absolute best LiveCodeBench scores.

The case for it

  • Broad benchmark coverage with consistent scores: Arena Text, Coding, Maths, Instruction Following and Creative Writing were all measured twice, with drift under 0.05 points in every repeated test.
  • Coding strength relative to its general performance: Arena Coding 1348.689, about 31 points above its general chat score.
  • Identical pricing across both tracked providers, so there is no arbitrage hunt needed.

The case against it

  • Maths is its weakest Arena category, at 1275.6013 — more than 42 points below its Coding and general chat scores.
  • LiveCodeBench performance is modest in absolute terms, at 35.5%.
  • No parameter transparency: the parameter count and any active-parameter figure remain undisclosed.

Nobody we watch has scored GPT-4o-mini (2024-07-18) for this. We would take the rating from Arena Agent (IPS).

WritingWe do not rate this

Scored, not ratedThe placings are on the right.

Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage. So we show where GPT-4o-mini (2024-07-18) placed and give it no mark out of five.

Arena Creative Writing 110th of 143 · 1294.2
Also scored, on boards we give no mark for
Arena Instruction Following 118th of 143

These tests check whether a model follows instructions — a precondition for all the work above, but not a measure of how well that work is done, which is why they get no rating.

Cheapest published offer

Why this differs from the header. The strip above quotes OpenAI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.

What each host's API supports

From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
