Batch Inference, Done Right
We built the infrastructure others didn't bother to optimize. The result? Faster delivery, lower costs, and guarantees you can count on.
Save up to 75% on every batch
We designed our hardware, runtime, and orchestration stack specifically for batch workloads—letting us pass on dramatically lower costs to you.
Guaranteed SLAs, or your money back
Choose 1-hour or 24-hour delivery windows. If we miss it, you don't pay. Simple as that.
1-Hour Batch SLA
The shortest guaranteed batch SLA available. Perfect for chained data processing and offline agent workflows.
Streaming Results
Results flow back as they're processed. No waiting for the entire batch to complete.
One-Line Migration
OpenAI-compatible API. Switch your endpoint, keep your code. Migration in minutes.
api.doubleword.ai/v1Built for Your Highest Volume Use Cases
From async agents to embeddings to image processing, we handle inference when it's at scale.
Async or Offline Agents
Autonomous agents that do long running background multi-step reasoning tasks.
Data Processing Pipelines
Process large datasets with LLM-powered analysis at scale.

It's simple: 1) Submit your batch via API and pick a 1hr or 24hr SLA. 2) We process it on our optimized batch infrastructure. 3) Receive results streamed as they complete—guaranteed on time.
We're not running at a loss or burning VC cash. Doubleword has built an inference stack optimized for high throughput and low cost from the ground up. By optimizing at every layer—hardware, runtime, and orchestration—we achieve significantly better unit economics than providers who bolt batch features onto real-time infrastructure.
We guarantee delivery. Unlike other providers who may expire your batch, we commit to your chosen SLA. If in the unlikely event we fail to meet it, we won't expire your request and you won't be charged.
Yes! Results are streamed as they're processed—you don't have to wait for every single request to complete before getting your first results.
We currently support popular open source LLMs and embedding models of various sizes in our private preview. We're actively adding more models and modalities based on user demand. Join the waitlist and let us know what models matter most to you.
Join our private preview waitlist below. We're onboarding users in batches (pun intended) and providing free credits to early adopters so you can test the platform at no risk.
