The short version

  • Only AI21 Labs has a free tier, so it costs nothing to try first.
  • Each has a real cost: AI21 Labs the free allowance is $10 of credit lasting 7 days rather than an ongoing free tier; 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: AI21 Labs covers Jamba models, 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.

AI21 Labs

  • The free allowance is $10 of credit lasting 7 days rather than an ongoing free tier
  • Jamba Large is $2 per million input tokens and $8 per million output, so output-heavy work costs four times as much as input
  • Volume discounts, private cloud hosting and higher rate limits require a custom plan
  • Standard rate limits are not published

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.

Answered from the vendors’ own pages

AI21 Labs: How much do AI21's Jamba Mini and Jamba Large models cost?

Jamba Mini costs $0.2 per 1M input tokens and $0.4 per 1M output tokens. Jamba Large is priced at $2 per 1M input tokens and $8 per 1M output tokens. Both models use usage-based billing with no monthly minimums.

Portworx: Is Portworx tied to Pure Storage hardware?

No. It runs on any Kubernetes distribution over any underlying storage, though Pure has owned it since 2020 and sets the roadmap.

AI21 Labs: Does AI21 offer a free trial?

Yes, AI21 provides a free trial with 10 USD in credits for 7 days, no credit card required. The trial grants access to all Foundation models via API and SDK.

Source
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.

AI21 Labs: How do AI21's custom plans and volume discounts work?

Custom plans with volume discounts are available for enterprises but require contacting sales. These plans can include premium API rate limits, private cloud hosting, priority support, dedicated account managers, and expert consultancy.

Source
Portworx: Is backup included?

No. Portworx Backup is a separately priced product covering Kubernetes application backup.

AI21 Labs: What does AI21 mean by 30% token efficiency savings?

AI21 claims their tokenization delivers approximately 30% more text per token compared to other providers, which can reduce effective costs by roughly 30%. This applies primarily to English-language text averaging 1 word or 6 characters per token.
