GPT-5.4 Nano vs Inkling
Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.
Inkling scores higher, GPT-5.4 Nano costs less — it depends on your workload.
Inkling is ahead by 2.3 points overall, and GPT-5.4 Nano lists 3.7× cheaper per blended million tokens. Whether 2.3 points is worth that depends on how much a wrong answer costs you. GPT-5.4 Nano also leads on measured cost per point of capability, at $0.0500 per point.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — GPT-5.4 Nano on top, Inkling below, both out of 100.
What each one costs to run
Per-token prices are hard to feel. These are monthly list costs for both models across five workload shapes, using each provider's published cached-input rate where there is one.

GPT-5.4 Nano vs Inkling FAQ
Which is better, GPT-5.4 Nano or Inkling?
Inkling scores higher, GPT-5.4 Nano costs less — it depends on your workload. Inkling is ahead by 2.3 points overall, and GPT-5.4 Nano lists 3.7× cheaper per blended million tokens. Whether 2.3 points is worth that depends on how much a wrong answer costs you. GPT-5.4 Nano also leads on measured cost per point of capability, at $0.0500 per point.
Is GPT-5.4 Nano cheaper than Inkling?
GPT-5.4 Nano is cheaper. On a 3:1 input:output blend, GPT-5.4 Nano lists at $0.463 per million tokens and Inkling at $1.72 — GPT-5.4 Nano is 3.7× cheaper. Input and output are priced separately — GPT-5.4 Nano charges $0.200 in and $1.25 out, Inkling charges $0.950 and $4.05 — so the model that looks cheaper flips depending on how output-heavy your workload is.
GPT-5.4 Nano vs Inkling: which scores higher on benchmarks?
GPT-5.4 Nano scores 69.6 and Inkling scores 71.9 overall on LiveBench, the mean of its seven categories. That is a 2.3-point lead for Inkling. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.
Which gives better value for money, GPT-5.4 Nano or Inkling?
GPT-5.4 Nano. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. GPT-5.4 Nano works out at $0.0500 per point and Inkling at $0.1766.
Does GPT-5.4 Nano or Inkling have a bigger context window?
Inkling has the larger context window: 400K for GPT-5.4 Nano against 1.0M for Inkling. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.
Do GPT-5.4 Nano and Inkling support prompt caching?
Both publish a cached-input rate: $0.020 per million for GPT-5.4 Nano and $0.160 for Inkling, against full input rates of $0.200 and $0.950. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced
- Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
- Scores — LiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
- Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
- “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
