## How they compare

Vertex AI offers 200+ models, including Gemini 3.8 and Claude, next to custom training on GPUs or TPUs, agent tooling, vector search and BigQuery integration. Gemini 3.8 Flash runs $0.75 in and $3.75 out per million tokens with a 1M window. OpenScale does one thing: it serves DeepSeek V4.1 Flash at $0.06 in and $0.24 out under a 50% promotion, with prepaid credits and no minimums.

Vertex fits enterprises already on Google Cloud that want governed agents close to their data. OpenScale fits developers and small teams who want the cheapest open model for coding agents without a cloud contract, and who can live with one model, one region and no SLA.

## 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.

### OpenScale

OpenScale is a Y Combinator-backed inference API built by LatentSpace and run out of Singapore. It sells open models behind one endpoint that speaks Chat Completions, the OpenAI Responses API and Anthropic Messages, so Claude Code, Codex, OpenCode, Cline, GitHub Copilot, Zed and other coding agents can point at it with a base URL and key. Its public catalog today is DeepSeek V4.1 Flash in two versions, standard and fast, both with a 1M token context window and up to 384K output tokens.
