Which is cheaper, Grok 4.5 or Grok Build 0.1?+
Grok 4.5 is $2.00 and Grok Build 0.1 is $1.00 per million tokens, so Grok Build 0.1 is cheaper on this metric. Grok 4.5 is $6.00 and Grok Build 0.1 is $2.00 per million tokens, so Grok Build 0.1 is cheaper on this metric.
Which has a larger context window, Grok 4.5 or Grok Build 0.1?+
Grok 4.5 has the larger sourced context window. Grok 4.5 supports 500,000 tokens and Grok Build 0.1 supports 256,000 tokens.
Which performs better in benchmarks, Grok 4.5 or Grok Build 0.1?+
There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.
Can Grok 4.5 or Grok Build 0.1 be self-hosted?+
Both models have the same sourced self-hosting status: unsupported. Grok 4.5 is not marked open weight; Grok Build 0.1 is not marked open weight.
Can Grok 4.5 and Grok Build 0.1 understand images?+
Grok 4.5 is documented with image input; Grok Build 0.1 is documented with image input. This reflects supported input modalities, not vision quality.
Which can generate longer answers, Grok 4.5 or Grok Build 0.1?+
Neither model has a sourced maximum output in this comparison, so a larger limit cannot be determined.
Do Grok 4.5 and Grok Build 0.1 support reasoning and tool use?+
Grok 4.5: reasoning, tool calling, and image input. Grok Build 0.1: reasoning, tool calling, and image input. Feature support does not establish relative quality.
Which is available from more inference providers, Grok 4.5 or Grok Build 0.1?+
Grok 4.5 has 1 sourced provider route; Grok Build 0.1 has 1, a tie.
Which offers better value, Grok 4.5 or Grok Build 0.1?+
There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
