Apxml
Estimate VRAM, compare GPU costs, and research model specifications and benchmarks for local or production LLM planning.
About Apxml
apxml helps engineers plan local and production LLM deployments before they commit to hardware. It brings together a VRAM calculator, GPU cost comparisons, a searchable model directory, model specifications, rankings, and benchmark data. Basic is free and covers standard calculations plus a public hardware library, so it works well for early hardware checks and single-node planning. Pro adds saved hardware profiles, concurrent-user and batch-size modeling, calculator API access, exportable fine-tuning and inference cost reports, and an ad-free interface. Pro+ includes those features with higher API limits and priority support. The site is especially useful for testing deployment assumptions and estimating GPU budget. Its numbers remain planning estimates rather than a substitute for benchmarking the exact workload and hardware. The free interface contains ads, while API access and detailed production workflows require a paid subscription.
Best for
Best use cases
Estimate VRAM for a chosen model before purchasing or assigning a GPU.
Compare GPU cost options while planning a single-node or multi-node deployment.
Export inference or fine-tuning cost assumptions for an internal planning discussion.
Compare before choosing
The free tier suits basic VRAM checks, while paid tiers cover production modeling and API workflows.
A model directory and calculator sit together, reducing context switching during hardware research.
Results are planning estimates, so teams still need direct tests for workload-specific performance.

Pros
- The $0 Basic plan covers standard VRAM estimates and a public hardware library.
- Model specifications, rankings, benchmarks, and hardware planning tools are available in one workflow.
- Paid plans add API access, saved profiles, exports, and concurrency modeling for production work.
Cons
- The free experience is ad-supported, which may distract from repeated planning sessions.
- Calculator API access and exportable cost reports require a paid subscription.
- Planning estimates cannot replace direct workload benchmarks on the exact target hardware.
