Fireworks AI vs OpenScale: key differences

Fireworks serves 400+ models with one of the fastest GPU stacks around, keeps the full 1M context on DeepSeek V4.1 Flash, GLM 5.3 and Kimi K3, and serves fine-tunes at base-model prices. It holds SOC 2, HIPAA and ISO certifications and offers dedicated GPUs. OpenScale serves DeepSeek V4.1 Flash with a 1M window at $0.06 in and $0.24 out under a 50% promotion, at 200+ tokens per second, with a faster tier at about twice the speed.

Fireworks is the pick for production teams that need certifications, many models or a post-training path. OpenScale is the pick for cost-first coding agents on one model, with setup guides for Claude Code, Codex and a dozen other agents.

What Fireworks AI and OpenScale do

Fireworks AI

Fireworks AI was founded in 2022 by former Meta PyTorch engineers led by CEO Lin Qiao, and it sells speed on open models. Its custom serving stack has posted 167 to 174 tokens per second on DeepSeek V4 Pro in third-party measurements, several times what most GPU peers hit on the same model. The catalog holds 400+ models across text, vision, audio and embeddings, served through an OpenAI-compatible API. In July 2026 it raised a $1.505B Series D at a $17.5B valuation, with a reported $1B+ run rate and 40T+ tokens a day.

Example models: DeepSeek V4.1 Flash, GLM 5.3, Kimi K3

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.
