Audited feedback from ML engineers running active workloads on Fireworks AI.
Serverless LoRA hot-swapping saved our startup $14,000/month
Verified: Production Multi-Tenant LoRA Serving“Instead of hosting 12 dedicated vLLM GPU instances for our fine-tuned customer models, Fireworks allows us to swap LoRAs dynamically in milliseconds on shared base weights. Best speculative decoding engine in the industry.”
