$1/$5 hosted Claude vs a cheap long-context open sibling. The alternative-to-Sonnet pair that is honest.
Huge window, cheap hosted lists. The Haiku alternative that is actually open-weight.
Official Anthropic list $1/$5. This is the SKU behind “cheapest Claude alternative” that is still Claude.
Jan 2025 reasoning model. Still searched. V4 Pro is the newer DeepSeek buy.
