GPT Proto Integrates Google’s Gemini 3.1 for Developers
GPT Proto, an API platform operated by Talent Tech Global Limited and based in Hong Kong, has integrated Google’s Gemini 3.1 Pro Preview into its unified developer API gateway. The integration gives developers access to Google’s latest multimodal model — released by Google in early 2026 — through GPT Proto’s RESTful API (compatible with OpenAI’s SDK) alongside models from OpenAI, Anthropic, Meta and others. Gemini 3.1 Pro Preview supports extended context windows, multi-step logical reasoning, and processing of text, code and structured data in a single call. GPT Proto’s gateway supports streaming, function calling, batch processing and model routing, and targets use cases such as RAG pipelines, code generation, automated content and analytics. Founder & CEO Sammi Cen said the addition removes separate onboarding or billing requirements for accessing Google’s model.
Integration expands developer access to a leading multimodal model (Gemini 3.1 Pro Preview) via a unified API, easing multi-provider model adoption for product teams; meaningful for AI product development but not industry-shifting on its own.

Gemini 3.1 Pro: Advanced reasoning for complex tasks
Google has rolled out Gemini 3.1 Pro, the latest in its Gemini AI family, designed to handle tasks where simple answers aren’t enough. Google claims 3.1 Pro delivers roughly double the reasoning performance of the November 2025–released Gemini 3 Pro, unlocking capabilities for complex data synthesis, visual explanations, and creative visuals in UX design and marketing workflows. The update follows Gemini 3 Deep Think, further emphasizing agentic workflows. Rollout is in Preview via the Gemini App for AI Ultra and Pro subscribers, with NotebookLM support, and API access through AI Studio, Antigravity, Vertex AI, Gemini Enterprise, Gemini CLI, and Android Studio. It’s also available in other environments such as the Perplexity AI Answering Machine. The article highlights use cases like generating data tables, creating animations, and even analyzing literary topics (e.g., Wuthering Heights) to inform websites or portfolios, illustrating Google’s push toward more capable, reasoning-focused AI tools.
Google's Gemini 3.1 Pro Shatters Benchmark Records Again!
Google unveiled Gemini 3.1 Pro, the latest iteration of its large language model, releasing a preview and announcing a forthcoming general availability. Independent benchmark results cited by Google — including Humanity’s Last Exam and Mercor’s APEX system — show Gemini 3.1 Pro outperforming its predecessor, Gemini 3. Brendan Foody, CEO of AI startup Mercor, said the model reached the top of the APEX-Agents leaderboard. The update comes amid intensified competition in advanced LLMs from rivals such as OpenAI and Anthropic and highlights rapid improvements in models designed for agentic, multi-step reasoning and professional tasks.
Google Gemini 3 Elevates Search and App AI
Google announces Gemini 3, its latest AI model, integrated directly into the Google Gemini App and activated in Search via AI Mode. The model promises multimodal understanding, nuanced responses, and generative layouts, with agentic capabilities that support multi-step tasks and coding. Gemini 3 is supported by a new Antigravity platform for Vibe Coding, enabling autonomous agent actions and app-level workflows; developers can access Gemini 3 through Google AI Studio, Vertex AI, Gemini CLI, and the new Agentric-Building platform Antigravity. The rollout emphasizes deep integration across Google services (Maps, Canvas, Chrome) and introduces enhanced AI capabilities for developers and end users. Google notes Gemini 3's broad reach (650 million monthly active users; 13 million developers) and cites performance benchmarks from internal assessments. Availability begins in the US for Pro/Ultra users, with broader deployment including Germany planned later. The company positions Gemini 3 as a major step in its AI strategy against competitors like OpenAI, Meta, and Anthropic.
