Multi-hour coding and document tasks at mid-tier pricing
xAI's long-horizon agent model — it finishes agentic tasks in roughly half the turns of its rivals, which makes it cheaper in practice than its per-token price suggests.
Verdict
Finishes agent tasks in half the turns — cheap where it counts.

Released August 12, 2026, succeeding Grok 4.5. Long-context billing is a cliff, not a ramp: at 200K tokens and above the whole request is charged at $4/$12. DeepSWE 65.9%, CursorBench 3.2 70.8%, FrontierCode 1.1 Extended 61.3%, Terminal-Bench 3.0 26.5%, APEX-Agents 57.5%.
xAI's first coding- and agent-focused model — the first full-scale deployment of the 1.5T-parameter V9 MoE base, trained with real developer-session data from Cursor.
Verdict
Best cost-per-solved-task coding agent — efficiency over ceiling.

Released July 8, 2026 on the 1.5T-parameter V9 base. Pricing verified on docs.x.ai: $2/$6 under 200K prompt tokens, $4/$12 above. Full access initially gated to SuperGrok Heavy; staged rollout to SuperGrok $30 tier. EU availability lagged launch.
Grok 3 Beta is xAI's flagship large language model, trained on a massive dataset with claimed real-time access to X (Twitter) data and strong reasoning capabilities. It competes directly with frontier models like Claude Sonnet 4 and GPT-4o across coding, analysis, and general tasks.
Verdict
A powerful but unproven flagship that earns its place for STEM and real-time social data use cases, but the beta tag means it's not yet ready to dethrone Anthropic or OpenAI at this price.

Pricing is asymmetric: input at ~$0.20/1M is excellent, but $1.50/1M output undercuts its budget appeal for generation-heavy use. Availability through xAI's API; check for rate limits and regional availability as xAI's infrastructure is still scaling.

xAI FAQ
What is xAI's best model in 2026?
Grok 4.7, released September 21, 2026, at $2/$6 per 1M tokens with a 500K-token window. The vendor's table shows 46.3% on CursorBench 4.0 and 37.6% on Terminal-Bench 4.0; independent testing found modest coding gains over Grok 4.6 and heavier token use per task. The original Grok 4 was retired from the API on May 15, 2026.
How does Grok compare to Claude and GPT?
Grok 4.7 trails Claude Opus 5.5 and GPT-6 Astra on the coding benchmarks all three vendors published, and xAI published no SWE-bench figure. Its edges are a low output price ($6 per 1M tokens) and real-time X access. Prompts above 200K tokens are billed at $4/$12.
How do I access Grok?
Through the xAI API, the Vercel AI Gateway and other hosts, and in the Grok app and on X with a SuperGrok subscription ($30/month) for the higher limits.
