DeepInfra vs Dolphin: key differences
DeepInfra lists DeepSeek V4 Flash at $0.09 in and $0.18 out and small models from $0.02 per million, with an OpenAI-compatible API and no contracts. Dolphin's API launched in October 2026 with one model, DeepSeek V4.1 Flash, at $0.01 in and $0.07 out per million, served on idle consumer GPUs. Validators check returned logprobs against a trusted copy of the model so nodes cannot swap in a smaller one, but Dolphin publishes no speed, context or SLA.
DeepInfra is the safer cost-first choice, with many models and normal signup, though teams should check quantization per model. Dolphin goes lower on price for one model, and fits teams that accept variable latency, want uncensored models and can sign up with a crypto wallet and Telegram.
What DeepInfra and Dolphin do
DeepInfra
DeepInfra is the price floor for open-model inference. Developers treat it as the reference point for what a token should cost, with small models like Llama 3.1 8B at $0.02 per million and DeepSeek V4 Flash at $0.09 in and $0.18 out. The catalog covers 150+ open models across text, image and speech behind a fully OpenAI-compatible API. There are no minimums, setup fees or contracts on the shared API.

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.
