Grok 4.3 is xAI's current flagship model, released to the public API on 2026-04-30 (beta on grok.com 2026-04-17). It is a reasoning-first, natively multimodal model — text, image, and native video input — with a 1,000,000-token context window and xAI's signature live access to the X (Twitter) corpus. The single sentence a buyer needs: it delivers frontier-class reasoning and the best real-time-data capability on the market at a price (just $1.25 in / $2.50 out per 1M tokens) that undercuts every comparable flagship by a wide margin — with the trade-off of slow first-token latency and unusually thin published benchmarks. Provider: xAI. Released: 2026-04-30. Status: GA. Context: 1M tokens. Max output: undisclosed. Modalities: text + image + video in, text out. Knowledge cutoff: December 2025. Headline price: $1.25 / $2.50 per 1M tokens.
