It scores 20.2% on LiveCodeBench, 75.2% on MMLU, and 8.00/10 on MT-Bench. With a 200K-token context window at $0.25/$1.25 per 1M tokens, it was the leading cost-efficient model in the Claude 3 family at launch. ## At a Glance **Where Claude 3 Haiku leads** - Fastest Claude 3 model — lowest latency in the family - $0.25/$1.25 per 1M tokens — highly cost-efficient - 200K-token context window - Vision capability at the mini price tier - 8.00/10 MT-Bench — solid instruction following **Where it lags** - 20.2% LiveCodeBench — below Claude Haiku 3.5 and current frontier models - 75.2% MMLU — lower than Claude Sonnet 3.x and Opus - Superseded by Claude Haiku 3.5 ($0.80/$4) for better performance - August 2023 knowledge cutoff — significantly outdated **Best for:** Legacy integrations validated on Claude 3 Haiku; high-volume classification and summarisation tasks where maximum throughput at minimal cost is the priority. ## What Claude 3 Haiku Is Claude 3 Haiku is the small-model tier of Anthropic's Claude 3 family, released March 13, 2024 — the same day as the full Claude 3 family launch. It introduced vision capability at a cost point below all previous Claude models, targeting high-throughput production use cases. The model was designed around near-instant responsiveness: at launch it was Anthropic's fastest model, suited for real-time user-facing applications and moderation pipelines where latency matters more than peak accuracy. Claude Haiku 3.5 replaced Claude 3 Haiku as the recommended small-tier model in October 2024, offering substantially better performance ($0.80/$4 per 1M — more expensive but much stronger). For new deployments, Claude Haiku 3.5 is the correct choice. Claude 3 Haiku remains available for existing integrations. ## Specifications | Field | Value | |---|---| | Organization | Anthropic | | Parameters | Undisclosed | | Context window | 200,000 tokens | | Max output | 4,096 tokens | | License | Proprietary (API only) | | Release date | March 13, 2024 | | Knowledge cutoff | August 2023 | | Modality | Text + Vision (multimodal) | ## Pricing | | Input (per 1M tokens) | Output (per 1M tokens) | |---|---|---| | Anthropic API | $0.25 | $1.25 | Prompt caching available.
