meta shipped muse ember today, their smallest model. $0.10 in / $0.50 out per million tokens, 1M context. haiku 5.5 and gpt-6 luna have the same list price, meta's pitch is it burns fewer tokens per task read the pricing page though. if one request goes over 200K input tokens the whole request bills at 3x ($0.30 / $1.50), not just the part past 200K. cached tokens count toward it. continuing a stored conversation counts the whole conversation so any agent loop that resends the full history every turn is gonna cross that line without anyone noticing, and the invoice just splits it into two tiers
