Grok 4.3

Grok 4.3 (April 2026) is xAI's flagship — a 1M-context, always-reasoning multimodal model with configurable 'effort', priced unusually low for a top-tier model.

Best for

• Strong general reasoning, coding and tool use
• Always-on reasoning with tunable effort (none→high)
• Long-context work up to 1M tokens with native video input
• Real-time, current-events questions via X integration

How it compares — and the India angle

• Priced aggressively for a flagship ($1.25/$2.50) — far cheaper per token than top GPT/Gemini/Claude tiers, easing cost for reasoning-heavy Indian startups.
• Closed-weight, so no self-hosting — for data-residency-sensitive Indian use (BFSI, govt) an open Llama may be preferable.
• Worth paying over open models when you need frontier reasoning + 1M context + video in one API without GPU ops.
