xAI releases Grok 3.5: real-time web access, 200K context, DeepSearch 2, and Aurora image gen

Think of Grok 3.5 as an AI assistant that does not just rely on what it learned during training. Instead, it can go out and browse the web in real time, find the latest information, and bring it back to you as part of its answer. That is a meaningful upgrade over AI models that only know what happened before their training cutoff.

A few things make Grok 3.5 stand out. The 200K context window means it can read and reason over very long documents in one go, like an entire legal contract, a thick technical manual, or a long back-and-forth conversation, without losing track of earlier content.

DeepSearch 2 is the upgraded research mode. Instead of running one search and summarizing the results, it builds chains of follow-up questions, drilling deeper into a topic step by step, much like a human researcher who keeps pulling on threads until they have a complete picture.

Aurora is an image generator baked directly into the model. You can ask Grok 3.5 to create an image mid-conversation without switching to a separate tool or pasting into a different service.

For everyday users on X Premium+, this means a smarter assistant that stays current and can handle more complex tasks. For developers, the API opens the door to building products on top of these capabilities. xAI is clearly aiming to challenge both OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.8 with this release.
