Our take
Pick AI21 if developers who will burn the $10 / 3-month credit while they open a first File Library, then add a card and pay the live per-token row on ai21.com/pricing — the public pricing HTML 403’d the day we fetched, so we do not invent a $/1M. Pick Together AI if developers who want one HTTP call to Llama/Qwen/DeepSeek-class models and will read the per-model row. Skip Together AI if people who want a local
hosted inference (and fine-tune) platform
