## How they compare

Sail serves Kimi K2.6, GLM-5.3, GPT-OSS 120B, Qwen 3.6, Gemma 4 and customer LoRA fine-tunes, discounted 30 to 85% against other hosts depending on how long you can wait, and adds Sailboxes for agents that run for hours. OpenScale serves DeepSeek V4.1 Flash at $0.06 in, $0.003 cached and $0.24 out per million tokens under a 50% promotion, at 200+ tokens per second, with a fast tier at about twice the speed. It speaks the Anthropic, OpenAI Responses and Chat Completions formats.

Sail is the more complete option for long background agents, batch work and fine-tunes across several models. OpenScale fits interactive coding agents on DeepSeek V4.1 Flash that want a low price without waiting on a slower window.

## What each one does

### Sail Research

Sail Research sells throughput over latency. Founders Neil Movva and Samir Menon built a serving stack that packs as much work as possible into every GPU, and customers state how long they can wait through completion windows. Its docs quote each window against traditional providers: the default asap window serves at low latency for 30 to 70% less, balanced for 45 to 80% less, and the off-peak flex window for 55 to 85% less. Batch requests default to flex, and LoRA and custom-tool requests default to balanced.

### OpenScale

OpenScale is a Y Combinator-backed inference API built by LatentSpace and run out of Singapore. It sells open models behind one endpoint that speaks Chat Completions, the OpenAI Responses API and Anthropic Messages, so Claude Code, Codex, OpenCode, Cline, GitHub Copilot, Zed and other coding agents can point at it with a base URL and key. Its public catalog today is DeepSeek V4.1 Flash in two versions, standard and fast, both with a 1M token context window and up to 384K output tokens.
