Efficient LLM Inference
Doubleword cuts token prices 50-90% for the same intelligence - optimized for high-volume workloads like background agents and batch processing.
Same intelligence, a fraction of the cost
Cost per 1B in + 1B out.Comparable model intelligence.
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. Meaning 50-90% cheaper inference than other inference providers for the same models!
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

“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
