Claude 3 Haiku Released
- Anthropic announced Claude 3 Haiku with Opus and Sonnet on 4 March 2024 as "available soon", and released it on 13 March in the Claude API and on claude.ai for Claude Pro subscribers[1][5]
- It launched on Amazon Bedrock the same day, with Google Cloud Vertex AI "coming soon"[1][4]
- Anthropic pitches it at enterprises that need to analyze large volumes of quarterly filings, contracts or legal cases "for half the cost of other models in its performance tier"[1][3]
- The model stayed on the Claude API for just over two years: deprecated on 19 February 2026 and retired on 20 April 2026 in favour of Claude Haiku 4.5[2]
Notable features
- The fastest and most compact Claude 3 model, priced at $0.25 per million input tokens and $1.25 per million output tokens - a 1:5 ratio built for long-prompt enterprise work[1][5]
- Processes 21K tokens (about 30 pages) per second for prompts under 32K tokens, "three times faster than its peers for the vast majority of workloads"; one US dollar buys analysis of 400 Supreme Court cases or 2,500 images[1][3]
- Benchmarks Anthropic reports: 75.2% on MMLU, 75.9% on HumanEval, 88.9% on GSM8K and 33.3% on GPQA Diamond, ahead of GPT-3.5 and Gemini 1.0 Pro on most rows[1]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
