Perplexity CEO shares early Gemini 4 Carbon evals: a record 0.857 on the WANDR deep-research benchmark at $5.86 per task, ahead of Argon and GPT-6 Astra
Perplexity CEO Aravind Srinivas posted early evals of Gemini 4 Carbon on X: it scored a record 0.857 on Perplexity's Wide-And-Deep-Research (WANDR) long-form research benchmark at $5.86 per task, versus 0.802 ($7.88) for Gemini 4 Argon and 0.735 ($13.34) for GPT-6 Astra. He called Carbon the strongest model Perplexity has seen for long-form research and answer quality, and said it will come to all Pro and Max users inside Perplexity Computer once there is enough token capacity.
Key Takeaways
- WANDR scores (per Perplexity): Gemini 4 Carbon 0.857, Gemini 4 Argon 0.802, GPT-6 Astra 0.735, GPT-6.1 Sol 0.654, Claude Opus 5.5 0.647, Claude Fable 5.1 0.601
- Cheaper too: Carbon costs $5.86 per task, below Argon at $7.88 and GPT-6 Astra at $13.34
- Cost frontier in Perplexity's chart: DeepSeek V4 Pro 0813 (0.359, $0.75), GPT-6 Sol (0.566, $2.23), GPT-6.1 Sol (0.654, $3.70) and Carbon
- Claude Sonnet 5.5 scored 0.550 ($2.73) and Grok 4.7 scored 0.528 ($9.30)
- Not live yet: Carbon reaches Perplexity Pro and Max users only once token capacity allows, and Google still limits early access to cyber defenders in its Fairwind program
