Anthropic API vs Black Forest Labs

Claude API uses pay-as-you-go pricing per million tokens (MTok). Haiku 4.5 costs $1 input/$5 output per MTok; Sonnet 5 costs $2 input/$10 output; Opus 5 costs $5 input/$25 output; Fable 5 costs $10 input/$50 output per MTok.

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.

Batch processing saves 50% on API costs. Prompt caching reduces token costs by up to 90% for cached reads (charged at 80% discount compared to standard rates). Fast Mode for Opus 5 costs 2x standard pricing for up to 2.5x faster response speeds.

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.

Self-serve access uses usage-based tiers with automatic rate limit increases as volume grows. Enterprise customers receive custom rate limits, monthly invoice billing, and hands-on support at negotiated pricing.

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.

US-only inference costs 1.1x pricing for input and output tokens across all model tiers compared to standard multi-region pricing.

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.

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