Claude 4 Haiku at $0.8/1M input and $4/1M output tokens. Best low-cost writing option for fast-moving content teams.
Claude 4 Haiku is the best capability-per-dollar pick in Anthropic's lineup (budget score 88/100). It handles fast budget writing, support automation, and cost-sensitive Anthropic integrations well — step up to Claude Fable 5.1 only where quality visibly falls short.
Claude 4 Haiku costs $0.8/1M input vs $10/1M for Claude Fable 5.1 — a 92% saving on input tokens.
Claude Sonnet 5 — 1M tokens at $2/1M input. Context is where budget models are least compromised: you usually lose reasoning depth before you lose window size, so a cheap model is often a perfectly good choice for summarising or extracting from long documents.
Less strong on deep reasoning and coding than larger models. Gemini 3.1 Flash-Lite is now cheaper with a larger context window. Avoid it if cost is your only concern — Gemini 3.1 Flash offers similar value with a larger context window.
On a moderate workload of 10M input and 2M output tokens, Claude 4 Haiku runs about $16.00 against $200.00 for Claude Fable 5.1 — a difference of $184.00 a month at the same volume. Output tokens dominate the bill on both, so the length of the responses you generate matters far more than the length of your prompts.
Mixing is almost always cheaper for the same quality. Route high-volume, low-stakes work — classification, extraction, first drafts, routine agent steps — to Claude 4 Haiku, and reserve Claude Fable 5.1 for the calls where a wrong answer costs real time. Teams that split this way typically cut spend substantially without a quality drop anyone notices, because most tokens in a real workload are not hard problems.
