# OpenAI: GPT-5 Nano (batch)

Provider: openai  
Category: llm  
Model ID: `openai/gpt-5-nano:batch`

GPT-5-Nano is the smallest and fastest variant in the GPT-5 system, optimized for developer tools, rapid interactions, and ultra-low latency environments. While limited in reasoning depth compared to its larger...

## Specs

- Context length: 400000 tokens
- Max output: 128000 tokens
- Modalities: text, image, file
- Released: 2025-08-07

## Pricing

- Input: $0.03 per million tokens
- Output: $0.20 per million tokens

## Verdict

GPT-5 Nano (batch) delivers GPT-5 reasoning at batch-optimized pricing — $0.03/Mtok input makes it the cheapest way to access OpenAI's latest architecture for high-volume workloads. The 400K context window handles long documents and multi-turn conversations without truncation. Trade-off: batch mode means 24-hour turnaround, so this isn't for real-time use. Reach for this when you're processing thousands of documents overnight or running evals where latency doesn't matter.
