I believe a price that’s 5x the price of Opus 4[1] is likely a real price (if you don’t simply mean they could’ve asked more since other AI companies are lagging behind, and there’s a compute shortage). Might even be a bit too high currently, and will very likely be too high in late 2026 (as better systems for inferencing it get online, and OpenAI releases its own Mythos counterpart). Under ideal conditions, when scale-up systems are big enough, the number of total params should barely influence costs of MoE model tokens, if everything else remains the same (the number of active params, memory per token of KV cache).
“Claude Mythos Preview will be available to participants at $25/$125 per million input/output tokens”. Current API price of Opus 4.6 is $5/$25 for input/output.
