## How they compare

Sail sells slowness on purpose. Customers pick a completion window: priority targets about a minute per turn for 30 to 50% off, standard about five minutes for 45 to 65% off, and flex runs off-peak for 60 to 80% off. Its serving stack packs as much work as possible into each GPU. Baseten optimizes for the other metric, with the lowest measured time to first token on the Artificial Analysis board in August 2026. Sail's own downsides rule out voice, live chat and interactive UI, which is exactly where Baseten fits best. For a background agent that runs for hours without a human, Sail's discounts decide it.

The catalogs overlap on open models. Sail serves Kimi K2.6, GLM-5, GPT-OSS 120B, Qwen 3.6 and Gemma 4, plus customer LoRA fine-tunes, over OpenAI and Anthropic-compatible APIs. Baseten serves Kimi K3, GLM 5.2 and gpt-oss 120B on the same two API shapes. Sail adds Sailboxes, persistent compute for agents that run indefinitely. Baseten adds HIPAA, data residency and Truss deployments for non-LLM models. A single product could send user-facing turns to Baseten and overnight research jobs to Sail.

## What each one does

### Baseten

Baseten runs two products. Model APIs serve a curated set of 13 open models, including DeepSeek V4, GLM 5.2, Kimi K3 and gpt-oss 120B, over endpoints that speak both the OpenAI Chat Completions shape and the Anthropic Messages shape. That dual compatibility means an existing OpenAI or Claude SDK, or a coding agent, points at Baseten with a base URL change. Dedicated deployments take any model you package with the open-source Truss CLI and bill per GPU minute, with an H100 at about $6.50 an hour.

### 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. The priority window targets about a one-minute turn for roughly 30 to 50% off the immediate asap price. The default standard window targets about five minutes for 45 to 65% off. The flex window runs off-peak for 60 to 80% off.
