BytePlus ModelArk Free Trial for New Users (500K tokens per model, over 10 million in total)
BytePlus (ByteDance's overseas cloud)
Free trial for new BytePlus users: LLMs get 500K tokens per model (over 10 million tokens in total), video models up to 2 million tokens, image models 200 images, speech synthesis 20 thousand characters, and speech recognition 20 hours; the official page says the quota does not expire but may change
Verbatim from the official BytePlus free trial page: "500K free tokens per model, with a total of over 10M tokens" "New user receive up to 2M video tokens and 200 free images" "Free trial for new BytePlus users: There is no charge to use these products up to their specified free quota. The free quota does not expire, but is subject to change. Available for eligible customers." The page lists the free quota model by model: LLM-class models (DeepSeek-V3, DeepSeek reasoning models, Kimi-K2, gpt-oss-120b, ByteDance-Seed-1.6 and its flash version, SkyLark-pro, etc.) get 500K tokens each, Seedream-series image models 200 images each, video models 2 million tokens, SeedTTS speech synthesis 20 thousand characters (voice cloning includes 1 more voice), and SeedASR speech recognition 20 hours.
The page notes "Available for eligible customers", and the specific eligibility conditions (region, whether real-name / enterprise verification or a card is required) are in "More rules", which was not opened for verification this time, so read the rules before claiming. The page's model list is dated (it still lists older models such as DeepSeek-V3 and Kimi-K2), and the models and quotas you can actually use are as shown in the console. The page also has an enterprise-verification data-cooperation reward campaign that ended on 2026-03-31, which is not part of this entry. This is a separate quota on the BytePlus international site and uses a different account system from the domestic Volcano Engine Ark (volcengine-ark); whether a mainland China phone number can sign up directly was not verified.
