The short version

  • Only Perplexity has a free tier, so it costs nothing to try first.
  • Each has a real cost: Perplexity context window has been stealthily reduced despite prior claims of 1-million-token capacity; Portworx bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • They diverge on capability: Perplexity covers Real-time web search, Portworx covers Container-native volumes.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification

Portworx

  • Bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • A 1,000 node hour monthly minimum applies, which means small or intermittent clusters pay for capacity they do not consume.
  • Replicating volumes across nodes consumes real capacity and network bandwidth, so the underlying infrastructure cost rises alongside the licence in a way the node hour rate does not show.
  • Pure Storage ownership means roadmap priorities are set by an array vendor, and buyers should confirm that hardware independence remains contractual rather than assumed.
  • Operating it well requires Kubernetes storage expertise, and teams that adopted Kubernetes to simplify operations often find they have added a distributed storage system to run.

Portworx: What does a real cluster cost?

At 0.33 USD per virtual node hour, twenty nodes running continuously is roughly 4,800 USD a month. Bare metal at 1.11 USD per node hour is around 16,000 USD for the same node count.

Perplexity: Can I use Perplexity offline?

No. Perplexity requires an active internet connection for all searches. The full answer service is not available offline.
