Grok 4.6 - access through LLMTR

xAI's flagship model for long coding sessions, multi-step agent flows, and heavy research work. It reads text and images together and fits production pipelines through tool calling and schema-constrained output. Thinking depth is tunable across low, medium, high, and xhigh so you can trade speed for depth; high is the default.
