A month of regular usemedian of 20 users active on 5+ days	$18.99	$24.74

Each logged request priced at the vendor’s list rates for its own token counts, including cache reads and any higher rate for long prompts. Average output: 698 tokens per request. Both models are priced on the requests up to 200K tokens that fit in both context windows; band shares above describe all requests.

Artificial Analysis runs Terminal-Bench 4.0 in its own setup, so its scores differ from the tbench.ai leaderboard.

What to watch for

Claude Haiku 4.5's 200K window cannot take 21% of coding-agent requests, so the comparison uses only requests both can take. Claude Haiku 4.5 is superseded: Claude Haiku 5.5 costs $0.013 per request. GPT-5.4 Mini scores as well or better on the benchmarks above, so the cheaper request is not bought with much lower ability.

FAQ

Is GPT-5.4 Mini cheaper than Claude Haiku 4.5 for coding agents?

Yes, at list prices. 100 average coding-agent requests cost $1.70 on GPT-5.4 Mini and $2.22 on Claude Haiku 4.5. A median 16-request session costs $0.20 vs $0.27. Measured on 79,301 real coding-agent requests (Sep 13 to Oct 12, 2026), counting only the requests up to 200K tokens that both can take.

How much does a month of Haiku 4.5 vs GPT-5.4 Mini cost?

For the median regular user in our data (1,478 requests in 30 days), about $24.74 on Claude Haiku 4.5 and $18.99 on GPT-5.4 Mini at list price. Heavier users pay proportionally more.
