Langtrain vs Others
Stop renting
intelligence.
Generic APIs are great for prototypes. Langtrain is for production. Own the weights, own the future.
01
Latency
Cloud APIs
Variable (500ms+)
Langtrain
Instant (<50ms)
Local inference eliminates network round-trips. Your model runs right next to your application logic.
02
Privacy
Cloud APIs
Data sent to API
Langtrain
Air-gapped
Zero data leakage. Training and inference happen on your infrastructure, never leaving your VPC.
03
Cost
Cloud APIs
$20/mo + tokens
Zero Token Tax
Langtrain
One-time compute
Stop paying rent on intelligence. Train once, run forever. No per-token tax eating your margins.
04

Rate limits & outages
Langtrain
100% Uptime
No dependency on OpenAI's status page. You own the model, you own the uptime.
Full Stack Connectivity
Deploy Your SLM Everywhere
A specialized model is only as powerful as the tools it can access. Langtrain connects your SLM to your entire ecosystem—from proprietary databases to custom Slack agents.
