Grok 4.6: specs, pricing and how it performs in a council

Grok 4.6 is xAI's model available on Council AI at $2.00 per million input tokens and $6.00 per million output, with a 500,000-token context window. xAI flagship (released Aug 12, 2026). Frontier performance on coding, knowledge work and STEM; ties GPT-5.6 on the Artificial Analysis index at the same $2/$6 as Grok 4.5. 500K context. On Council you do not run it alone: the same prompt goes to up to 10 models from different labs in parallel, and a moderator synthesizes one answer with a consensus score showing where the labs agreed.

What Grok 4.6 is good at

xAI flagship (released Aug 12, 2026). Frontier performance on coding, knowledge work and STEM; ties GPT-5.6 on the Artificial Analysis index at the same $2/$6 as Grok 4.5. 500K context.

Council surfaces it for: reasoning, coding, current-events, agents.

It has native web search, so it can ground answers in current sources rather than training data alone.

Grok 4.6 pricing on Council AI

Council does not resell tokens. Every paid plan carries a monthly budget and each model draws against it at cost: $2.00 in / $6.00 out per million tokens for Grok 4.6. Plans start at $19.99/mo (Plus), $39.99/mo (Pro) and $99.99/mo (Ultra, which adds the personal RAG library and MCP server).

If budget is the binding constraint, GLM-5.3 is the cheaper seat in the lineup at $1.40/$4.40.

Using Grok 4.6 in a council

A single model — this one included — can be confidently wrong. Council runs Grok 4.6 alongside models from other labs on the same prompt, then scores how much they agreed. High consensus is a signal you can act on the answer; low consensus surfaces the specific point they split on, which is usually the part worth checking yourself.

Other xAI models in the lineup: Grok 4.3, Grok 4.20 (Long-Context).
