## How they compare

DeepInfra serves 150+ open models with no minimums, from $0.02 per million tokens on Llama 3.1 8B. On DeepSeek V4 Flash it charges $0.09 in and $0.18 out, and on DeepSeek V4 Pro $1.30 in and $2.60 out in FP8 with 1M context. Boundless lists DeepSeek V4 Flash at $0.04 in and $0.21 out and DeepSeek V4 Pro at $1.04 in and $2.08 out, also with 1M context. Some DeepInfra endpoints run FP4, and neither provider offers fine-tuning.

DeepInfra is the pick for cost-first bulk work across a wide catalog, once teams check precision per model. Boundless fits input-heavy DeepSeek workloads and teams that want engineers to run a reserved deployment against contracted targets. It also resells GPT and Claude on the same API and keeps zero data retention.

## What each one does

### 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.

### Boundless

Boundless launched in September 2026 as an inference partner for AI-native startups. It sells two things. The Model API serves pre-tuned models on shared capacity, billed per token from prepaid credits with a budget per API key. Tailored inference reserves capacity for one customer, and Boundless engineers pick the model on the customer’s own evals, tune precision, batching, caching, speculative decoding and parallelism, then run the deployment against uptime, throughput and latency targets written into the contract. A free two-week evaluation tests those targets on real traffic against the customer’s current provider first.
