Notes

OpenAI's workhorse tier. Cache read price estimated at ~10% of input (verify against openai.com/api/pricing). Cache Write 5m/1h N/A — OpenAI uses automatic caching with no separate write cost. Batch: 50% off. US-only: 1.1× uplift. Verified May 28, 2026. [2026-07-12] Price unchanged ($0.25/$2.00 per devtk.ai + pricepertoken.com), but GPT-5 mini is NO LONGER LISTED on OpenAI's official pricing page as of June 2026 — succeeded by GPT-5.4-mini. Candidate for Deprecated status; Khaled to decide. No price fields touched. [2026-07-13] Still absent from OpenAI pricing search results this run (GPT-5.4 mini $0.75/$4.50 and GPT-5.6 Luna now occupy this tier). No source disputes $0.25/$2.00 but no fresh confirmation either — verification produced no clear result. Prices untouched; deprecation decision still pending with Khaled. [2026-07-20] Verification attempt produced no clear result — recheck next run. Aggregator (pricepertoken) now shows $0.125/$1.00, but that is its cheapest-across-providers figure ("cheapest input fell 50% from $0.250"), not confirmed official OpenAI list pricing, and the model remains delisted from OpenAI's pricing page per prior runs. Conflicting sources → prices untouched. Deprecation decision still pending with Khaled. [2026-07-29] Verification attempt produced no clear result — recheck next run. Search confirms GPT-5 mini remains delisted from OpenAI's official pricing page (succeeded by GPT-5.4 mini $0.75/$4.50 and GPT-5.6 Luna $1/$6). No official price confirmation available. Prices untouched; deprecation decision still pending with Khaled. [2026-08-10] Verification attempt produced no clear result — recheck next run. Still delisted from OpenAI's official pricing page; devtk.ai still lists $0.25/$2.00 while aggregator cheapest-across-providers figures ($0.125/$1.00) remain unofficial. Prices untouched; deprecation decision still pending with Khaled. [2026-08-17] Verification attempt produced no clear result — recheck next run. Sixth consecutive inconclusive run. Search now describes GPT-5 mini explicitly as a "deprecated variant" (released Aug 7, 2025) at $0.125/$1.00 while GPT-5.4 mini ($0.75/$4.50) is the current mini tier; pricepertoken shows it still served by 3 providers. No official OpenAI list price. Prices untouched. RECOMMENDATION: set Status = Deprecated — six runs without an official price and an explicit third-party "deprecated" label is enough signal; leaving it Live risks the calculator quoting an unverifiable rate. [2026-09-28] Verification attempt produced no clear result — recheck next run. Seventh consecutive inconclusive run. GPT-5 mini still not found on OpenAI's official pricing page; only older-dated aggregator pages (devtk.ai, getapipulse — undated/stale) still show $0.25/$2.00 with no fresh September 2026 confirmation. Prices untouched. RECOMMENDATION UNCHANGED (now 7 weeks running): set Status = Deprecated. [2026-10-10] Verification attempt produced no clear result — recheck next run. anotherwrapper (Sep 2026) still lists $0.25/$2.00; pricepertoken still $0.125/$1.00; morphllm confirms GPT-5 mini is not on OpenAI's official pricing page. Prices untouched. RECOMMENDATION UNCHANGED: set Status = Deprecated. [2026-10-12] Max Output Tokens 16,384 → 128,000 per OpenAI's GPT-5 mini model page (developers.openai.com/api/docs/models/gpt-5-mini: 400K context, 128K max output), corroborated by PromptHub + LLM Gateway listings. PRICES NOW OFFICIALLY CONFIRMED: the same model page lists Input $0.25 / Cached $0.025 / Output $2.00 — all match stored values, so the $0.125/$1.00 figures were batch/reseller rates. The page now steers new workloads to GPT-5.6 Terra, but OpenAI names GPT-5 mini as the successor to o4-mini, so it is still a supported model. Deprecation recommendation can be relaxed.
