xAI's Grok models — reasoning models with a large context window and tight access to real-time data from X.
Glossary
Grok 4.6 Grok
Grok 4.6 (August 2026) is xAIs flagship model for long-running agentic work — 500k-token context, text and image input, tiered pricing from 2/6 USD per million tokens.
Grok 4.5 Grok
Grok 4.5 is xAI's July 2026 frontier model for coding, agentic tasks and knowledge work — high token efficiency at $2 input and $6 output per 1M tokens.
Grok 3 Grok
Reasoning model from xAI (Elon Musk's AI company), released on 17 February 2025. Trained on the Colossus supercluster, with 'Think' reasoning and DeepSearch plus real-time access to X. Proprietary access via the Grok app and API.
Grok 4 Grok
Grok 4 is xAI's reasoning model from July 2025 — text and image input, 256k context, trained via reinforcement learning on the 200,000-GPU Colossus cluster.
Grok 4.1 Grok
Grok 4.1 is xAIs AI model released in November 2025. It delivers more natural dialogue, fewer hallucinations and better style control, and comes in two variants: one that answers directly and one that reasons before responding (Thinking).
Grok 4.3 Grok
