# OpenAI vs Sail Research

> OpenAI sells immediate answers from closed models; Sail sells open-model answers minutes later for 30 to 80% off. The deciding factor is how long a task can wait.

## How they compare

Sail Research is built around a trade OpenAI only partly offers. Customers pick a completion window: priority targets about a one-minute turn for roughly 30 to 50% off Sail's immediate price, standard targets about five minutes for 45 to 65% off, and flex runs off-peak for 60 to 80% off. OpenAI's closest lever is Batch, which halves every price. Sail serves open models such as Kimi K2.6, GLM-5, GPT-OSS 120B and Qwen 3.6, plus customer LoRA fine-tunes, over OpenAI-compatible APIs, and claims 3x to 10x savings over comparable hosts.

Sail explicitly does not suit voice, live chat or any interactive UI, and teams that need GPT or Claude quality have to look elsewhere. That is exactly where OpenAI lives: customer-facing assistants, computer use on GPT-6 Astra, and Fast mode for speed. Sail's strength is background agents that run for hours without a human, supported by Sailboxes that give agents persistent compute. Code-review startup Detail.dev uses it for agents that scan a codebase for three to four hours. Many teams could split traffic this way, OpenAI in the foreground and Sail in the background.

## What each one does

### OpenAI

OpenAI runs the most widely adopted closed-model API. Its September 2026 lineup has GPT-6 Astra at the top for computer use, coding and long agentic runs, priced at $10 in and $50 out per million tokens. Below it sits the GPT-5.6 family: Sol for hard professional work, Terra as the balanced default, and Luna for high-volume jobs at $0.20 in and $1.20 out. All of them carry a 1.05M token context window with up to 128K output.

### 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.
