The short version

  • Each has a real cost: Black Forest Labs open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.; 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: Black Forest Labs covers FLUX 3 image generation, 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.

Black Forest Labs

  • Open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.
  • Video generation pricing per second can become costly for longer or higher-resolution outputs compared to subscription-based competitors.
  • No consumer subscription plan; pricing is oriented toward developers and enterprises rather than casual creators.

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

Black Forest Labs: How much does Black Forest Labs' API cost?

The API is pay-as-you-go with no subscription required; video generation costs $0.17 per second, so a 5-second HD clip costs about $0.85.

Source
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.

Black Forest Labs: Is there a free plan?

No free tier is offered; the pricing page lists only pay-as-you-go API usage and paid open-weights licensing tiers starting with Builder.

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.

Black Forest Labs: What do the open-weights licensing tiers include?

Builder includes FLUX.2 [klein] models with 10K images/month for one domain; Platform and Professional raise the cap to 100K images/month and add FLUX.2 [dev] access and fine-tuning rights.

Source
Portworx: Is backup included?

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

Black Forest Labs: Can I self-host FLUX models?

Yes, open weights licenses let teams download and self-host FLUX.2 [klein] and FLUX.2 [dev] models on their own infrastructure under the Builder, Platform, and Professional tiers.

Source
Black Forest Labs: How do I get enterprise or high-volume pricing?

Enterprise plans covering custom volume, all model releases, and SLA guarantees are not published and require contacting Black Forest Labs' sales team directly.
