Claude Haiku 4.5specs & pricing
Verified Sep 4, 2026 against the AI Gateway catalog
Priced at $1/1M input and $5/1M output tokens, placing it above true budget models like Gemini Flash but below mid-tier flagships. Confirm availability of extended thinking or tool-use features via Anthropic's API documentation, as Haiku-tier models sometimes receive these capabilities later than Sonnet/Opus.
Exceptional throughput for high-volume API workloads at $1/$5 input/output pricing
200K context window matches Claude Sonnet 4.6 in capacity, rare for a budget-tier model
Strong instruction-following and structured output quality relative to its price class
Noticeably faster response latency than Claude Sonnet 4.6 or Opus, suitable for real-time chat and agentic loops
Weaknesses
Lags behind Claude Sonnet 4.6 and GPT-4.1 mini on complex multi-step reasoning and nuanced analysis
Not competitive with flagship models for deep research synthesis or creative writing requiring stylistic depth
No native image generation capability; multimodal input is limited compared to Gemini 3.1 Flash
Real-world use cases
What people actually use Claude Haiku 4.5 for.
Automating code review comments across hundreds of PRs daily in a CI/CD pipeline

High-volume production pipelines, customer support bots, and real-time text processing where cost and latency are critical constraints.
Claude 3.5 Haiku is Anthropic's fastest and most affordable model in the Claude 3.5 family, designed for high-throughput tasks requiring quick responses without sacrificing Claude's core instruction-following quality. It handles a massive 200K context window while maintaining speed suitable for production pipelines.
Verdict
The fastest way to get Claude's quality in production — just don't confuse 'fast' with 'cheap'.

Output cost of $4/1M is notably higher than competing fast/mini models. Input cost at ~$0.80/1M is competitive. Best value emerges in input-heavy pipelines like document classification or RAG retrieval where output tokens are minimal.
High-volume, latency-sensitive applications like chatbots, classification, data extraction, and agentic tool use where speed and cost matter more than peak reasoning depth.
Claude 3.5 Sonnet is Anthropic's mid-cycle flagship model, balancing strong reasoning, coding, and instruction-following with a 200K context window. It sits between Haiku and Opus in Anthropic's lineup, offering near-flagship quality at a lower cost than top-tier models.
Verdict
One of the best models for coding and complex instruction-following, but its premium pricing demands premium use cases.
