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.; DeepInfra focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
  • They diverge on capability: Black Forest Labs covers FLUX 3 image generation, DeepInfra covers Open model hosting.

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.

DeepInfra

  • Focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
  • Model selection is limited to what DeepInfra chooses to host, unlike self-managed platforms.
  • No published free tier; usage is billed from the first token.

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
DeepInfra: Is there a free tier on DeepInfra?

No free tier is published; usage is billed pay-as-you-go from the first token, though a credit card or pre-payment is required before you can send requests.

Source
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
DeepInfra: How is usage priced?

Language models are billed per million input/output tokens, other models by inference execution time, and audio models per minute of audio processed, with no minimum commitment.

Source
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
DeepInfra: What are the Standard, Priority, and Flex tiers?

Standard is default best-effort pricing at 1x, Priority costs 1.5x for faster time-to-first-token during peak demand, and Flex costs 0.8x for non-production or asynchronous workloads.

Source
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
DeepInfra: How does billing scale with spend?

Accounts advance through usage tiers as cumulative payments cross $20, $100, $500, $2,000, and $10,000 thresholds, with invoices generated monthly or at each threshold.

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.

Source
DeepInfra: Is there a limit on concurrent requests?

Yes, accounts are limited to 200 concurrent requests by default, though spending limits can also be configured to prevent unexpected charges.
