| Price basis | Meta Model API standard-tier list price, per 1M tokens, with no long-context premium — the tier on which Meta states prompts and completions are not used for training. A cheaper contributor tier ($0.10 input / $0.20 output per 1M) trades training rights and a far lower rate limit (60 vs 3,000 requests/min) for the discount, so it is not the tracked list price. Search grounding is billed separately per 1,000 queries and is not included in the token rate. | — |
