## How they compare

Sail Research asks customers how long they can wait. Its priority window targets about a one-minute turn for 30 to 50% off the immediate price, standard targets about five minutes for 45 to 65% off, and flex runs off-peak for 60 to 80% off. The catalog covers Kimi K2.6, GLM-5, GPT-OSS 120B, Qwen 3.6 and Gemma 4, plus customer LoRA fine-tunes, and Sail claims 3x to 10x cost savings over comparable hosts. Mistral serves its own models on demand: Small 4 at $0.15 in and $0.60 out per million tokens, Large 3 at $0.50 in and $1.50 out, and Medium 3.5 at $1.50 in and $7.50 out, with Batch at half price and 256K context.

Latency tolerance is the decision. Sail is explicitly unsuited to voice, live chat or interactive UIs, and is built for background agents that run for hours, with Sailboxes giving them persistent compute. Code-review startup Detail.dev uses it for agents that scan a codebase for three to four hours. Mistral fits interactive coding and chat, and its Agents API adds built-in tools. Mistral also offers EU or US regions, a Priority Tier SLA, cloud marketplace listings and self-hosting on as few as four GPUs. Sail serves customer LoRA fine-tunes directly, while Mistral's fine-tuning API is deprecated in favor of its enterprise Forge system.

## What each one does

### Mistral AI

Mistral AI is a Paris lab that sells its models through La Plateforme, its own API, and releases most of them as open weights. It consolidated the lineup in 2026. Mistral Medium 3.5, released April 28, is a dense 128B model that merges instruction following, reasoning and coding into one set of weights, and it replaced both Devstral 2 and the Magistral reasoning models. It costs $1.50 in and $7.50 out per million tokens and scores 77.6% on SWE-Bench Verified by Mistral's count. Mistral Small 4, a 119B mixture-of-experts model with 6.5B active, costs $0.15 in and $0.60 out. Mistral Large 3, a 675B MoE under Apache 2.0, runs $0.50 in and $1.50 out. All three carry a 256K context window.

### 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.
