Model Performance / Benchmarks
No published coding benchmarks.
xAI does not publish SWE-Bench Verified, Terminal-Bench, LiveCodeBench, ARC-AGI, or any other third-party coding benchmark results for Grok models. The Grok 4.20 model page claims "industry-leading speed and agentic tool calling capabilities" and "the lowest hallucination rate on the market" but provides no supporting data or benchmark citations. The Grok 4.3 page claims "leading the industry in non-hallucination rate, agentic tool calling, and instruction following capabilities" without citing benchmarks.

Community Signals
Reddit r/LocalLLaMA - "Grok Build CLI, agents-cli, and the CLI coding tool gold rush" (14 days ago, 0 upvotes, 8 comments): A discussion thread comparing Grok Build CLI to other CLI coding agents. Multiple commenters expressed skepticism about Grok Build's pricing and maturity. User ridablellama wrote: "i want to try grok build but this 99 dollar deal exist and no way i'm paying 100 more than my claude 20x max for grok beta product." User sn2006gy commented: "Grok dropped grok build, but that's for a $300.00 plan actually that they're running a special on if you can get it for $99 and the new limits suck and not to mention the general model is bad." User JimmyBenHsu noted: "Vendor lock-in is what keeps me from committing to any ecosystem-tied tool. Grok Build looks convenient, but I've been burned before by building workflows around a provider that changes pricing or axes features."

Overall community sentiment: Community discussion around xAI's coding tools is sparse and largely critical. The dominant themes are: (1) Grok Build CLI is seen as a late entrant to an already crowded CLI coding agent market, (2) the $30/mo SuperGrok price point is viewed as reasonable but the reportedly $300/mo SuperGrok Heavy tier is considered expensive relative to the beta quality of Grok Build, and (3) developers prefer model-agnostic tools like Aider over vendor-locked solutions.

Transparency Gaps
- SuperGrok Heavy pricing is undisclosed. The pricing page lists Free, SuperGrok Lite, SuperGrok, SuperGrok Heavy, Business, and Enterprise columns but only shows prices for Free ($0), SuperGrok ($30/mo), and Business ($30/user/mo). SuperGrok Lite and SuperGrok Heavy prices are hidden. Community reports indicate $300/mo for Heavy with a $99 promotional price, but this is unconfirmed.
- Usage limits are not quantified. The Free tier is described as having "generous limits" and SuperGrok has "higher rate limits." No concrete numbers (messages/day, requests/hour, tokens/month) are published for any consumer plan.
- No published coding benchmarks. xAI does not submit Grok models to SWE-Bench, Terminal-Bench, LiveCodeBench, or any recognized coding benchmark. Claims of "industry-leading" performance are unsupported by public data.
- Knowledge cutoff is 18+ months old. All Grok models have a knowledge cutoff of November 2024. For coding tasks involving recent libraries, frameworks, or APIs, Grok relies on web search tools rather than training data.
- Grok Build 0.1 is in "public beta" / "early access." The model and CLI are explicitly labeled as beta. No timeline for GA or stability commitment has been published.
- No batch API pricing. xAI does not offer or document a batch processing tier at reduced rates, unlike Anthropic (50% discount) and OpenAI (50% discount).
- Enterprise pricing is fully opaque. No per-seat pricing, volume discount tiers, or committed-use pricing is publicly available. All enterprise terms require a sales conversation.
- IP indemnity status is unknown. Unlike Anthropic, OpenAI, and Google, xAI does not publicly state whether it offers IP indemnity for Grok outputs. Not mentioned in any documentation or legal pages reviewed.
