About Claude Haiku 4.5

Claude Haiku 4.5 is built for speed and scale: chat assistants, classification, extraction, moderation and other high-throughput tasks where latency and unit cost decide the architecture.

It keeps the Claude quality bar surprisingly high for its class, supports extended thinking when you need it, and prompt caching drives repeated-context costs down further.

On Sozdai you can use Claude Haiku 4.5 two ways with one account and one credit balance: chat in the browser playground on this page, or call it programmatically through an OpenAI-compatible endpoint. Pricing is pure pay-as-you-go per token with no subscription.

Why Claude Haiku 4.5

Speed & unit economics

Near-instant responses at the lowest price in the Claude line — built for high-volume production traffic.

Claude quality, small package

Punches above its weight on everyday tasks; optional thinking for trickier ones.

OpenAI-compatible API

Point your existing OpenAI SDK at our base URL and it just works — streaming, tool calling, usage accounting included. Anthropic-native /v1/messages is supported too.

Prompt caching, up to 90% off

Mark stable context (system prompts, tools, documents) with cache_control and repeated tokens are billed at a fraction of the input price.

One balance for everything

Web chat and API share the same credit balance and transparent per-token pricing. No subscription, no minimums.
