It supports vision, function calling, structured outputs, and web search, with a 500K-token context window for large engineering tasks.
Compared with its same-family predecessor [[sibling:grok-4-3|Grok 4.3]], Grok 4.5 shifts emphasis toward agentic coding and end-to-end app building, from challenging Rust and C/C++ tasks through production. Where Grok 4.3 was positioned as a general-purpose flagship, Grok 4.5's strengths lie in reasoning quality and engineering tasks.
On xAI's own reported benchmarks, Grok 4.5 scores 62.0% on DeepSWE 1.0, 83.3% on Terminal Bench 2.1, and 64.7% on SWE Bench Pro resolve rate. These figures are vendor-reported and measured within provider-specific harnesses.
The model also succeeds earlier Grok generations such as [[sibling:grok-4-20|Grok 4.20]] and its [[sibling:grok-4-20-multi-agent|multi-agent variant]], and complements xAI's separate agentic coding tool [[sibling:grok-build-0-1|Grok Build]].

"Best price" and the seller table are live AntSeed catalog data (advertised $/1M tokens — or $ per generated image for unit-billed image models — not settled amounts). Reputation = on-chain trust (0-100). "Routing" = the SDK's default buyer routing (what the VPR desktop app ships with): a trust ≥ 60 gate on the effective reputation, then cheapest-first among routable sellers; live failover state (per-peer cooldowns) is buyer-side runtime and not included. Model knowledge (TLDR, provider, About) via the VeniceStats enrichment layer. Advertised catalog, not the model used in any specific purchase. "Usage on AntSeed" counts only settlements whose buyers share the per-model split on-chain (metadata v2/v3, opt-in), so every usage figure is a lower bound.
