Cost Optimised LLM Inference
Stop paying the real-time premium for non-blocking workloads. If your application doesn't require millisecond latency, route your jobs through our async or batch queues and save up to 90%.
Same intelligence, a fraction of the cost
Cost per 1B in + 1B out.Comparable model intelligence.

“Using Doubleword's Batch inference has significantly scaled up our ability to do agentic evals and dataset generation thanks to the highly scalable inference of the best open source models, at a fraction of the cost of other providers.”
Alan Mosca · CTO, nPlan
“Doubleword is the first inference provider that just runs our batch jobs reliably and fast, with a clean async API and a UI that actually helps.”
Cristian Frunze · Founder, Ken AI
“The Doubleword team worked with us on batch annotation at scale. Their API made it economically viable to run two full annotation passes plus two cross-validation passes over 119K images with frontier reasoning models.”
Maziyar Panahi · Founder, OpenMed
“Doubleword's batch and async pricing tiers let us match each workload to the right cost-latency tradeoff. We're paying 50 to 80% less for background work that doesn't need real-time latency.”
Max Mednikov · CTO & Co-Founder, UnaGo AI
“Doubleword is our inference layer — it lets us enable multiple use cases across the business with a single point of governance and control. It fits seamlessly into our data platform and has unlocked use cases that weren't possible before due to scale and strict requirements.”
Rek Chong · Sr. Director, Solutions & Insights, Element Materials
The largest volume of tokens comes from asynchronous AI workloads.
Interactive chat is a small slice of AI inference. The real volume - agents, pipelines, evals, data enrichment - runs continuously and is throughput-constrained, not latency-constrained. We've built an inference stack that maximises GPU utilization, throughput, and cost-efficiency for large-scale asynchronous inference.
Background Agents
Long-running agents executing tasks autonomously at scale
Batch Processing
Large-scale document extraction, summarization, and classification
Evaluations
Run evals and benchmarks continuously without rate limits
Data Enrichment
Power tagging, routing, moderation, and ETL pipelines
Synthetic Data
Generate training and fine-tuning datasets at scale
Offline Jobs
Queue and process millions of requests reliably
Doubleword's APIs are the most efficient for every SLA
OpenAI compatible for easy migration. Full tool calling and structured generation support. Trade latency for cost. Pick the window that fits your workflow.
