GPT-5 Nano

GPT-5 Nano by OpenAI excels in the Coding category, where it ranks #174 with a composite score of 46/100. 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... It is particularly strong in areas highlighted by its top benchmark performance and adoption metrics, making it suitable for both individual developers and enterprise teams looking for a reliable coding solution.

GPT-5 Nano is priced at $0.05 per million input tokens and $0.40 per million output tokens (USD). Contact the provider for volume discounts and enterprise pricing. Pricing is competitive within the coding category and reflects the model's quality-to-cost ratio.

In the Coding category, GPT-5 Nano holds rank #174 out of 339 models tracked. Its quality rank is #174 and adoption rank is #174. You can use our comparison tool at /compare to see detailed side-by-side metrics with specific alternatives. Key differentiators include its composite scoring across benchmarks, community sentiment, and real-world adoption rates.

GPT-5 Nano has been evaluated across 6 different signals. Its strongest areas include Capabilities (83/100), Benchmarks (48/100), Pricing (100/100). These scores are derived from industry-standard benchmarks, community ratings, and real-world performance metrics. The composite score of 46/100 reflects a weighted combination of all tracked signals.

GPT-5 Nano is a paid model, though some providers may offer trial credits or limited free tiers for evaluation. Check OpenAI's website for current free tier availability and promotional offers.

GPT-5 Nano supports a 400K token context window (400,000 tokens total). That translates to roughly 300,000 words in a single prompt. This is large enough to process entire codebases, research papers, or long conversation histories in one shot.

GPT-5 Nano supports image understanding (vision), function/tool calling, structured JSON output, extended reasoning/chain-of-thought, streaming responses. Function calling lets you integrate it with external APIs and tools programmatically. Vision support means it can analyze images, screenshots, and diagrams alongside text. These capabilities determine which workflows and integrations the model can handle natively.

GPT-5 Nano was developed by OpenAI. It was released on August 7, 2025. You can access it through OpenAI's API. Check our provider page for all models from OpenAI and how they compare against each other.

Pick GPT-5 Nano when you need a budget-friendly option for high-volume, simpler tasks where you prioritize cost over peak performance. If your task is straightforward text completion or classification, a cheaper model might give you 90% of the quality at a fraction of the price. Run a quick benchmark on your actual use case before committing.

You can access GPT-5 Nano through OpenAI's API using standard HTTP requests or their official SDK. Most providers support OpenAI-compatible endpoints, so switching between models often requires changing just the model name in your API call. Streaming is supported for real-time token-by-token output. For production use, implement proper error handling, rate limiting, and cost monitoring.
