## How they compare

Claude models from Haiku 5.5 to Fable 5.1 lead on real-world coding benchmarks and ship with a 1M token window, priced from $0.10 to $10 in and $0.50 to $50 out per million tokens. They are sold direct and on Bedrock, Vertex AI and Microsoft Foundry. OpenScale serves open DeepSeek V4.1 Flash at $0.06 in, $0.003 cached and $0.24 out under a 50% promotion, and its Anthropic Messages endpoint lets Claude Code run against it with a base URL and key.

Anthropic is the pick when task success on hard coding or long unattended runs matters more than the bill. OpenScale is the cheaper option for teams that want to keep Claude Code as the harness but run an open model underneath, accepting a gap in model quality for a much lower price.

## What each one does

### Anthropic

Anthropic sells the Claude family of closed models through its own API, Amazon Bedrock, Google Vertex AI and Microsoft Foundry. The public lineup today runs from Claude Fable 5.1 at the top, released September 1, 2026, through Opus 5.5 ($4 in, $20 out) and Sonnet 5.5 ($2 in, $10 out) down to Haiku 5.5. List prices span a hundredfold range, from $10 in and $50 out on Fable to $0.10 in and $0.50 out on Haiku. All four tiers have a 1M token context window. The top three bill it at standard pricing, while Haiku 5.5 charges more past 100K.

### 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.

## Which is best, and when
