Perplexity Computer 将 Grok 4.5 作为编排模型，在 WANDR 基准测试中得分 0.328，每次试验成本 $4.76。该成绩超越了 Opus 4.8（0.254 分，$9.46）和 GPT-5.6 sol（0.289 分，$2.64）。WANDR 评估需要搜索、计算和多步推理的复杂研究任务。Grok 4.5 以约 Opus 4.8 一半的成本取得最高分，现面向 Consumer Pro 和 Max 订阅用户开放。
For Perplexity Computer, Grok 4.5 became the strongest orchestrator, scoring 0.328 (WANDR benchmark score) at $4.76 per trial.
- Opus 4.8 (high, thinking) scored 0.254 at $9.46, despite much higher cost.
- GPT-5.6 sol (medium) cost $2.64 but reached only 0.289 on the same test.
Perplexity Computer basically lets an orchestrator assign research, coding, browsing, and document work across subagents.
The WANDR benchmark measures difficult research jobs requiring search, computation, and sustained multi-step reasoning.
Grok 4.5 beat five tested configurations, including Opus 4.8, on Perplexity’s evaluation.
The WANDR evaluates whether an agent can complete large, professional research tasks that require searching many sources, running computations, organizing results, removing duplicates, checking evidence, and producing a complete structured answer. Perplexity describes these as “wide research” tasks involving the orchestration of search, compute, and model reasoning.
Grok 4.5 is now available as an orchestrator model in Computer for Consumer Pro and Max subscribers. We evaluated it against five other orchestrator configurations on WANDR. It scored higher than every other configuration at roughly half the cost of Opus 4.8.在 X 查看被引用的帖子
