Respuesta breve:<\/strong> as of July 23, 2026, neither original API model is current. xAI retired Grok 4.1 Fast<\/a> on May 15, 2026 and routes its old reasoning and non-reasoning slugs to Grok 4.3. Google shut down Gemini 3 Pro Preview<\/a> on March 9, 2026 and tells developers to migrate to Gemini 3.1 Pro Preview.<\/p>\n\n\n\n

For a new project, the more useful comparison is Grok 4.5 vs Gemini 3.1 Pro<\/strong>. Gemini publishes the broader mixed-media input set and a 1,048,576-token input limit. Grok 4.5 publishes a 500,000-token context, lower output-token pricing for prompts below 200,000 tokens, and first-party Web Search and X Search tools. The right choice depends on your files, tools, latency target, and cost per accepted result.<\/p>\n\n\n\n

GlobalGPT brings multiple model routes into one place<\/a><\/strong>, including Grok 4.1 Fast, Grok 4.3, Gemini 3 Pro, and Gemini 3.1 Pro labels on its current model list. GlobalGPT is a third-party platform, so its model labels, limits, and billing are its own service terms; they do not keep a retired xAI or Google API endpoint active.<\/p>\n\n\n\n

\n

Official model status, checked July 23, 2026:<\/strong> calls to grok-4-1-fast-reasoning<\/code> are now served by grok-4.3<\/code> with low reasoning effort, while calls to grok-4-1-fast-non-reasoning<\/code> are served by grok-4.3<\/code> with no reasoning effort. Google lists gemini-3-pro-vista previa<\/code> as shut down and directs developers to change to gemini-3.1-pro-vista previa<\/code>. New integrations should use an explicit current model ID and rerun quality, latency, tool-use, and cost tests.<\/p>\n<\/blockquote>\n\n\n\n

The original model names remain useful for migration searches, but they no longer describe two active official API endpoints. The table below separates the retired models from the current models a developer can intentionally select.<\/p>\n\n\n\n

xAI specifically recommends Grok 4.3 as the migration target for retired Grok 4.1 Fast workloads, while Grok 4.5 is its current flagship model for code and broader agentic work. Google directly recommends Gemini 3.1 Pro Preview as the replacement for Gemini 3 Pro Preview. Because one replacement is a preview model and both providers can change routing, pin the exact model ID returned in your logs.<\/p>\n\n\n\n

Gemini has the clearer published advantage for mixed-media input and long prompts. Grok has the lower listed output rate below 200,000 prompt tokens and a dedicated X Search tool. Neither advantage proves higher answer quality for every task.<\/p>\n\n\n\n
