Sail Research vs Dolphin

Both trade latency for price. Sail does it with completion windows on a funded platform; Dolphin does it with idle consumer GPUs.

Sail Research vs Dolphin: key differences

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% depending on how long you can wait. It raised $80M and reports trillions of tokens a week. Dolphin launched its API in October 2026 with one model, DeepSeek V4.1 Flash, at $0.01 in and $0.07 out, on consumer GPUs with no published speed, context or SLA, and signup through a crypto wallet and Telegram.

Sail is the more complete option for long-running agents and batch work, with a wider catalog, fine-tunes and sandboxes. Dolphin is very cheap on its one model and hosts uncensored models, but uptime is less predictable and its signup will not clear most procurement teams.

What Sail Research and Dolphin do

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.

Example models: Kimi K2.6, GLM-5.3

Dolphin

Dolphin began in 2023 as Eric Hartford's series of open-source, uncensored fine-tunes, trained to drop the refusals and baked-in guidelines of their base models so that the developer sets the rules through the system prompt. Current releases include Dolphin Llama 3.1 8B and Dolphin Mistral 24B Venice Edition, built with Venice, and the project publishes nearly 100 models on Hugging Face. It also runs a chat app, a Telegram bot and a synthetic data service that generates answers to commonly refused prompts.

Example models: DeepSeek V4.1 Flash, Dolphin Mistral 24B
