What is 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.
Price is the pitch. With a 50% promotion, standard DeepSeek V4.1 Flash costs $0.06 in, $0.003 cached and $0.24 out per million tokens at 200+ tokens per second, and the fast version runs about twice as fast for $0.28 in and $1.10 out. OpenScale publishes a comparison claiming its effective price on cache-heavy agent traffic is 49% below the next cheapest host. Billing is prepaid credits with no minimums. Chat and Messages requests are processed in memory and never stored, and one switch turns off the 30-day retention on Responses API state. Its terms note that some models may be served by third-party providers.
OpenScale pros, cons and use cases
