Key takeaways

A post estimate states that describing 76,000 photos would cost about $52.44 based on a per-photo cost example.
OpenAI self-reported benchmarks indicate GPT-5.4-nano can outperform the prior GPT-5 mini when run at maximum reasoning effort.
OpenAI introduced GPT-5.4-mini and GPT-5.4-nano as additions to the GPT-5.4 model released two weeks earlier.
The author released llm version 0.29 with support for the new GPT-5.4 mini and nano models.
OpenAI priced GPT-5.4-nano at $0.20 per million input tokens, $0.02 per million cached input tokens, and $1.25 per million output tokens.

How do GPT-5.4-mini and GPT-5.4-nano compare on independent third-party evaluations across representative tasks, at matched reasoning-effort settings and operational constraints (latency and token budgets)?
What are the practical throughput and latency characteristics of GPT-5.4-nano at different reasoning-effort settings in production-like environments?
What token usage distribution (input and output) occurs when describing large, heterogeneous photo libraries using the referenced approach, and how sensitive is total cost to output verbosity?
What are the corresponding prices for GPT-5.4-mini (and any other adjacent tiers) in the same pricing scheme, to enable direct cost-performance comparisons within the lineup?
Is there any clear operator, product, or investor decision-readthrough beyond general awareness of new model tiers and pricing?

Lower per token pricing for a nano tier may expand addressable high volume use cases where unit economics matter, increasing experimentation and potential usage across price sensitive workloads.
Model tier expansion to mini and nano suggests segmentation by cost and reasoning effort, potentially shifting demand toward smaller models for throughput and latency constrained applications.
Rapid tooling support in a popular integration tool may reduce adoption friction for the new tiers, accelerating developer testing and short cycle deployment.

Independent third party evaluations show nano and mini competitive quality at matched reasoning effort, latency, and token budgets versus prior mini and similar priced alternatives.
Production like benchmarks demonstrate strong throughput and predictable latency for nano across reasoning effort settings, with stable cost per task for representative workloads.
Clear pricing disclosure for mini and adjacent tiers enables cost performance comparisons and developers report migrating workloads based on improved unit economics.

Third party tests show nano quality materially worse than prior mini at comparable constraints, requiring higher reasoning effort or longer outputs that erase cost advantages.
Real world latency or throughput for nano at useful reasoning settings is poor or highly variable, limiting suitability for high volume production workloads.
Token usage for tasks like photo description is higher than expected or highly sensitive to verbosity, making total cost unpredictable and reducing practical savings.
