Anthropic
Claude Opus 4.8Prior Opus generation still billed at $5/$25. Kept as a compare baseline against Opus 5.
Meta
Llama 4 ScoutMeta open-weight Llama 4 long-context sibling of Maverick. Common public API lists sit near $0.08–$0.30 / $0.30–$0.70 per 1M; we store a conservative hosted list until OpenRouter overwrites.

$1/$5 hosted Claude vs a cheap long-context open sibling. The alternative-to-Sonnet pair that is honest.
Opus 4.8 still bills $5/$25. We keep it so Opus 5 vs 4.8 is a real generation delta, not marketing.
Huge window, cheap hosted lists. The Haiku alternative that is actually open-weight.
