About Grok 4.3
Grok 4.3 is xAI's high-volume text model, shipped to the xAI API at the end of April 2026 after an April beta for SuperGrok and X Premium+ subscribers. xAI positions it as the fast, reliable workhorse of the lineup, with strong tool calling and instruction following, a 1-million-token context window, and per-token prices well below its predecessor Grok 4.20. It matters beyond its own release: on May 15, 2026, xAI retired a swath of older Grok slugs and redirected their traffic to Grok 4.3.
Independent benchmarking framed it as a price-and-speed play rather than a frontier bid, sitting a step behind the top OpenAI and Anthropic models while undercutting them on cost. On artifio.ai it runs alongside 100+ models in one workspace from a single wallet.
Features
- 1,000,000-token context window, with a separate higher rate applied to requests beyond 200K tokens.
- Text and image input with text output.
- Configurable reasoning effort across four levels: none, low, medium, and high.
- Function calling and structured outputs, plus server-side web search and X search tools.
- Cached input tokens billed at a fraction of the standard rate.
- Document generation in consumer surfaces: formatted PDF reports, multi-sheet spreadsheets, and slide decks.
- Knowledge cutoff of December 2025 unless search tools are enabled.
What people use it for
- Agentic pipelines that need many tool calls per task at a low per-token cost.
- Long-document analysis and codebase-scale context work within the 1M-token window.
- High-volume production workloads such as classification, extraction, and summarisation.
- Report, spreadsheet, and slide generation for office-style deliverables.
- Drop-in replacement for retired Grok 3 and Grok 4 era model slugs.
Reported strengths
- Scored 53 on the Artificial Analysis Intelligence Index, 4 points above Grok 4.20, while cutting input price by roughly 37 percent and output price by roughly 58 percent.
- Jumped 321 Elo on the GDPval-AA agentic benchmark to 1500, passing Gemini 3.1 Pro Preview and Kimi K2.5.
- Strong instruction following: 98 percent on tau-squared-Bench Telecom and 81 percent on IFBench.
- One of the cheapest 1M-context reasoning models on the market at launch.
