## How they compare

DeepInfra is where many developers check what a token should cost. Llama 3.1 8B runs $0.02 per million and DeepSeek V4 Flash $0.14 in and $0.28 out, across 150+ open models with no minimums, setup fees or contracts. Vertex AI sits at the other end of the buying process. It is a Google Cloud platform with Gemini 3.8, Claude, Gemma and media models, where pricing is usage-based and split across services, and where training, pipelines, vector search and governance come bundled. One is a cheap endpoint. The other is an enterprise program.

The trade-offs are quality controls and customization. DeepInfra reaches its price partly through quantization: its FP4 DeepSeek V4 Pro caps context at 66K, and some reviewers report weaker output unless they pin FP8 variants. It also has no managed fine-tuning. Vertex offers custom training on GPUs or TPUs and runs much of Google's first-party serving on TPUs, at the cost of lock-in and hard-to-forecast bills. Bulk extraction, tagging and synthetic data fit DeepInfra. Governed agents over enterprise data fit Vertex.

## What each one does

### Google Vertex AI

Vertex AI is Google Cloud's enterprise AI platform. At Google Cloud Next on April 22, 2026, Google rebranded it the Gemini Enterprise Agent Platform with an agent-first structure, though the API endpoint and most docs still say Vertex. Model Garden offers 200+ models, including Google's Gemini 3.8 family, Anthropic's Claude models and open models like Gemma, alongside Imagen, Veo and Chirp for media and speech. Google's own TPUs sit underneath much of its first-party serving.

### 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 $0.14 in and $0.28 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.
