GPT Image 2 vs Nano Banana 2 comparison (AI image generators)

GPT Image 2 vs Nano Banana 2 comparison (AI image generators) shows GPT Image 2 holding a measurable lead in public benchmarks, including a 242-point advantage on the leaderboard. OpenAI has scheduled a May 12 shutdown for older models DALL-E 3 and GPT Image 1.5, and GPT Image 2 supports up to 4K resolution and can generate up to eight coherent images per prompt. Access is tiered between Instant Mode for all ChatGPT users and Thinking Mode for Plus, Pro, and Business, with an official API opening in early May.

GPT Image 2 (model identifier gpt-image-2) is built on the GPT-5.4 backbone and is presented as a production-capable image generation model. The model supports output up to 4K resolution and can produce up to eight coherent images per single prompt, enabling multi-image generation in one request. Batch consistency across generated images is described as a new primitive for production workflows, indicating consistent attributes or composition across multiple outputs. These capabilities are described in technical terms without detailing internal generation mechanisms.

OpenAI reports approximately 99% character-level accuracy for text rendered by the model across multiple scripts, specifically Latin, CJK, Hindi, and Bengali. Access to the model is provided in tiered user modes: Instant Mode is available to all ChatGPT users, while Thinking Mode is restricted to users on Plus, Pro, and Business plans. The description of access modes specifies the user classes associated with each mode but does not enumerate functional differences beyond availability. No pricing or leaderboard placement details are included in this section.

OpenAI’s official API for GPT Image 2 is scheduled to open to developers in early May. Direct access to GPT Image 2 via ChatGPT or third-party proxies is reported to cost roughly $0.01–$0.03 per image. API pricing for GPT Image 2 is listed as $8 per million input tokens and $30 per million output image tokens. These figures present both per-image direct access costs and token-based API rates for programmatic use of the model.

By contrast, Nano Banana 2 is priced at $60 per million output tokens at equivalent resolution tiers. The provided pricing statement for Nano Banana 2 applies to output token billing at comparable resolution settings. The comparison in this section lists the documented per-image and per-token rates for GPT Image 2 alongside the published output-token rate for Nano Banana 2 without further analysis or interpretation.

GPT Image 2 and Nano Banana 2 are competing AI image generators; GPT Image 2 is represented in public benchmarks as holding a measurable lead and offers production-focused capabilities including high-resolution output, multi-image generation per prompt, and batch consistency across generated images.

Access to GPT Image 2 is offered in tiered user modes alongside programmatic API availability, while Nano Banana 2 is described with output-token billing at equivalent resolution tiers.
