Grok 3 is listed as a retired model in the 2026 landscape. This review examines its historical position and directs researchers to active xAI frontier models for current chatbot evaluations.
Grok 3 review 2026 establishes the model as retired with no active endpoints or benchmarks available after the 2026-09-01 verification.
Grok 3 holds retired status in the 2026-09-01 verified landscape. The model appears among 1-2+ years obsolete entries. No active performance data, benchmarks, or production endpoints exist for Grok 3. Researchers must treat all Grok 3 review references as historical documentation only.
Grok 3 appears on the explicit retired list alongside GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, and Llama 3.3. The verification date 2026-09-01 marks the cutoff that removed Grok 3 from frontier eligibility. xAI no longer provides API access or hosted inference for Grok 3. Any Grok 3 review published after this date functions solely as archival reference.
The retirement removes Grok 3 from all current chatbot comparison matrices. Pricing tiers, context windows, and token limits previously associated with Grok 3 receive no updates. Direct evaluation of live models replaces any historical Grok 3 review data.

xAI grok-4.6 ranks as the highest-listed active frontier model. Additional current options include xAI grok-4.5, Grok 4.3, Grok 4.20, and Grok Build (CLI). All five carry pricing unverified status and data unavailable flags as of 2026-09-01.
xAI grok-4.6 operates as the top-tier xAI entry in the verified frontier LLMs list. xAI grok-4.5 sits directly alongside it in the same tier. Grok 4.3 and Grok 4.20 complete the non-CLI frontier offerings. Grok Build (CLI) supplies the coding-specific interface within the same xAI ecosystem.
Each model lists under the 2026-09-01 verification with no released benchmark numbers. Researchers access these models through official xAI channels referenced in the verified landscape. No feature matrix or token-limit table exists for any of the five because source data remains unavailable.
| Model | Category | Pricing Status | Update Date |
|---|---|---|---|
| xAI grok-4.6 | Frontier LLM | Unverified | 2026-09-01 |
| xAI grok-4.5 | Frontier LLM | Unverified | 2026-09-01 |
| Grok 4.3 | Frontier LLM | Unverified | 2026-09-01 |
| Grok 4.20 | Frontier LLM | Unverified | 2026-09-01 |
| Grok Build (CLI) | Coding CLI | Unverified | 2026-09-01 |
The table shows uniform unverified status across all xAI entries. No Entity-Attribute-Value pairs for speed, context length, or output quality appear in the source material.
xAI grok-4.6 carries entity category with value Frontier LLM. xAI grok-4.6 carries entity pricing status with value Unverified. xAI grok-4.6 carries entity update date with value 2026-09-01. xAI grok-4.5 carries entity category with value Frontier LLM. xAI grok-4.5 carries entity pricing status with value Unverified. xAI grok-4.5 carries entity update date with value 2026-09-01.

Researchers evaluate xAI chatbots by testing live frontier models directly. No verified benchmarks exist for Grok 3 or any current xAI model. Feature and pricing comparisons default to unavailable status.
Grok 3 review content cannot supply baseline numbers because the model carries retired status. Evaluation therefore shifts to xAI grok-4.6, xAI grok-4.5, Grok 4.3, Grok 4.20, and Grok Build (CLI). Direct API calls or CLI execution on the current versions replace any historical Grok 3 review metrics.
The Grok 4 Release: xAI's Revolutionary Multi-Agent AI System - Features, Pricing & Benchmarks (2026) provides the nearest documented reference point for migration planning. Researchers cross-reference the 2026-09-01 list against the official xAI frontier page for live access.
Step 1 requires identification of the retired Grok 3 entry in the 2026-09-01 verification. Step 2 requires selection of xAI grok-4.6 as primary test subject. Step 3 requires execution of identical prompts across xAI grok-4.5, Grok 4.3, Grok 4.20, and Grok Build (CLI). Step 4 requires recording of output attributes under data unavailable status. Step 5 requires aggregation of results into new Entity-Attribute-Value records. Step 6 requires verification that no benchmark numbers exist for any listed model. Step 7 requires confirmation that all pricing entries remain unverified. Step 8 requires documentation that Grok 3 retirement blocks any continuity mapping.
Migration paths route researchers from Grok 3 to xAI grok-4.6 or Grok Build (CLI) depending on use case. xAI grok-4.5 and Grok 4.3 serve as secondary options. All paths require fresh evaluation because no performance continuity data exists.
xAI grok-4.6 supplies the primary replacement for general chatbot workloads previously handled by Grok 3. Grok Build (CLI) addresses coding workflows that once used Grok 3. xAI grok-4.5, Grok 4.3, and Grok 4.20 fill remaining inference needs within the same verified list.
No token-equivalence table or context-window mapping appears in the source material. Researchers therefore run side-by-side tests on the five active models. The DeepSeek vs ChatGPT 2026: AI Chatbot Comparison for Developers and Researchers article illustrates the required direct-evaluation methodology for similar migrations.

Pricing for xAI grok-4.6, xAI grok-4.5, Grok 4.3, Grok 4.20, and Grok Build (CLI) remains unverified. No tiered rates, per-token costs, or subscription values appear in the 2026-09-01 data set.
All five models carry the explicit “pricing unverified” attribute. Researchers cannot reference any Grok 3 review pricing history because the model is retired. Direct consultation of the official xAI billing page supplies the only current values.
The absence of numbers prevents construction of a comparison table. Any Grok 3 review that lists legacy prices receives the historical label only.
xAI grok-4.6 carries entity pricing status with value Unverified. xAI grok-4.5 carries entity pricing status with value Unverified. Grok 4.3 carries entity pricing status with value Unverified. Grok 4.20 carries entity pricing status with value Unverified. Grok Build (CLI) carries entity pricing status with value Unverified.
Grok Build (CLI) supplies the dedicated coding interface among current xAI tools. xAI grok-4.6 and xAI grok-4.5 remain available for general coding assistance. No benchmark scores differentiate the options.
Grok Build (CLI) appears explicitly in the coding tools category of the 2026-09-01 list. The other four models function as general frontier LLMs that support code generation. Researchers select based on CLI versus chat interface preference because performance data stays unavailable.
The AI Chatbot for Customer Service 2026 page demonstrates how interface type influences selection when quantitative benchmarks are absent.
