Hong Kong-based API platform adds Google’s latest multimodal model to its growing roster, expanding developer access to frontier AI through a unified gateway
GPT Proto, a multi-model AI API platform operated by Talent Tech Global Limited, today announced the integration of Google’s Gemini 3.1 Pro Preview into its developer API gateway. The addition marks the platform’s latest expansion of its model catalogue, which now spans offerings from Google, OpenAI, Anthropic, Meta, and other leading AI labs.
Gemini 3.1 Pro Preview, released by Google in early 2026, is the company’s most capable multimodal model to date. It supports extended context windows, multi-step logical reasoning, and the processing of text, code, and structured data within a single API call. The model has drawn attention from the developer community for its performance on complex reasoning tasks and its applicability to agentic workflows and large-scale document analysis. For a detailed integration guide, see the Nano Banana 2 Guide on the GPT Proto developer blog.
Expanding Access to Frontier Models
GPT Proto’s platform provides a unified RESTful API compatible with OpenAI’s SDK, allowing development teams to access multiple AI models through a single integration point. The platform currently supports dozens of models and is designed for use cases ranging from software engineering and scientific research to content generation and business intelligence pipelines.

According to the company, the inclusion of Gemini 3.1 Pro Preview responds to growing demand from its developer user base for access to Google’s latest generation of models. GPT Proto states that all models on the platform are accessible through a standardised API interface, eliminating the need for teams to manage multiple provider accounts or API keys.
