Together AI

Pros

  • + Switched one pipeline across four serverless models in an afternoon — only the base URL and model string changed
  • + Model table publishes context length, cached pricing and quantisation format (NVFP4/FP8/MXFP4) per model
  • + Flash-tier pricing ($0.15-$0.30 input) made a 10M-token/day extraction job far cheaper than frontier equivalents
  • + Breadth: chat, image, vision, video, audio, embedding, rerank and moderation under one API
  • + $800M raise at $8.3B valuation (July 2026) is a strong continuity signal for an infrastructure vendor

Cons

  • - No proprietary frontier models; my messy scanned-forms task needed a frontier fallback
  • - No published per-model latency figures — you must measure for yourself
  • - Fine-tuning pricing (tokens x epochs, per-model rates) takes real digging to budget
  • - Experimental and free-tier models sit in the same list as production ones with no quality signal
  • - Dedicated GPU cluster options exist but are not as configurable as pure compute providers

Fireworks AI

Pros

  • + DeepSeek R1 Fast reached 80-95 output tokens/sec in my low-batch tests, close to the vendor's 90 tok/s serverless figure
  • + Grammar-constrained decoding on DeepSeek V3 returned schema-valid JSON on all 200 extraction calls in my batch
  • + LoRA SFT on a 7B-class model went from dataset upload to deployable adapter in under an hour, served at base-model pricing
  • + Training price card is fully public: $0.50/1M tokens (LoRA SFT, <=16B) up to $10.00/1M (>300B), DPO double
  • + On-demand GPU pricing is published per hour (H100/H200 $8, B200 $13, B300 $15) with zero charge for start-up time

Cons

  • - Open models only — my scanned-forms extraction task needed a frontier fallback Fireworks does not offer
  • - Same model prices differently across Standard/Priority/Fast paths, and third-party trackers disagree with the vendor blog
  • - DeepSeek R1 model card lists serverless as unsupported while a Fast serverless deployment exists — documentation contradicts itself
  • - Self-serve stops at shared serverless: R1 fine-tuning, QAT, region pinning and enterprise rate limits are sales-gated
  • - Shared-serverless latency is load-dependent by the vendor's own statement, so demo numbers are not an SLA
