## How they compare

Inference.net began by buying idle GPU capacity across data centers and passing the discounts on. Its OpenAI-compatible Batch API takes up to 1M requests per file with completion windows from 24 hours to 7 days. Mistral runs its own models synchronously: Medium 3.5 at $1.50 in and $7.50 out per million tokens, Small 4 at $0.15 in and $0.60 out, and Large 3 at $0.50 in and $1.50 out, with 256K context. Mistral's own Batch halves those prices. Inference.net publishes few independent benchmarks or public pricing comparisons, so buyers depend on its numbers, while Mistral lists rates openly. For interactive traffic Mistral fits better, since fragmented spare capacity suits batch work over strict real-time SLAs.

Customization is where Inference.net pushes hardest. Its Inference Gateway routes to open, closed or custom models under one key, captures every request, and turns that traffic into eval and training datasets. It then fine-tunes a task-specific model and serves it on a dedicated GPU with a 99.99% uptime target. Mistral deprecated its self-serve fine-tuning API and moved custom training to Forge, an enterprise pre-training, post-training and RL system. Mistral wins on distribution, with Azure, Bedrock, Vertex AI, Snowflake and watsonx listings, EU or US regions, and self-hosting on as few as four GPUs. A team could route general traffic to Mistral and distill narrow tasks on Inference.net.

## 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.

### Inference.net

Inference.net started as a buyer of last resort for idle GPU time. Its scheduler aggregates small unused chunks of capacity across data centers and runs models on them, and it passes the steep discounts it gets from those data centers on to customers. That origin still shows in its OpenAI-compatible Batch API, which takes up to 1M requests per file with completion windows from 24 hours to 7 days and far higher headroom than synchronous limits.
