GPT-5.4 mini and GPT-5.4 nano, which can describe 76,000 photos for $52
Highlights
- ▸GPT-5.4-nano redefines the price floor for capable models — $0.20 per million tokens input, cheaper than Gemini Flash-Lite
- ▸Describe 76,000 photos for $52 — the workloads that used to need enterprise justification are now weekend-project budgets
- ▸GPT-5.4-nano at max reasoning effort beats the previous GPT-5-mini — the capability curve is moving faster than the price curve, and both are moving

OpenAI today: Introducing GPT‑5.4 mini and nano. These models join GPT-5.4 which was released two weeks ago.
OpenAI’s self-reported benchmarks show the new 5.4-nano out-performing their previous GPT-5 mini model when run at maximum reasoning effort. The new mini is also 2x faster than the previous mini.
Here’s how the pricing looks—all prices are per million tokens. gpt-5.4-nano is notably even cheaper than Google’s Gemini 3.1 Flash-Lite:
| Model | Input | Cached input | Output | | --- | --- | --- | --- | | gpt-5.4 | $2.50 | $0.25 | $15.00 | | gpt-5.4-mini | $0.75 |…
