About ByteDance Seed: Seed-2.0-Lite
ByteDance Seed: Seed-2.0-Lite is a text model from ByteDance Seed, the model family developed by ByteDance. It sits in the text category and is positioned by its provider as a versatile, cost efficient enterprise workhorse, with the emphasis on strong multimodal and agent capabilities and noticeably lower latency than heavier alternatives. It was released by the provider on 2026-03-10.
The model accepts text, images and video as input and returns text. Its context window is 262144 tokens, and the maximum output is 131072 tokens, so long inputs and long generations are both workable within a single request. Because the input side is multimodal, you can send a prompt that mixes written instructions with image or video content and get a single text response back, which keeps pipelines simple when the source material is not purely textual.
Those capabilities point to a fairly wide set of practical uses. Document and media review is one: feed in a long report, a screenshot set or a video clip and ask for a summary, extraction or classification. Agent style workloads are another, since the model supports tool calling and structured outputs, which suits workflows that need to call functions, fill in schemas or drive multi step tasks. Long context tasks such as searching across large transcripts, contracts or knowledge bases also fit, and the low latency claim makes it a reasonable default for production traffic where response time matters.
You call it through api14's OpenAI-compatible API using the model id "bytedance-seed/seed-2.0-lite". The supported request parameters are frequency_penalty, include_reasoning, max_tokens, reasoning, reasoning_effort, response_format, stop, structured_outputs, temperature, tool_choice, tools and top_p. That covers the usual sampling controls, output length, stop sequences, structured output formats, and tool use, plus reasoning controls for adjusting how much internal reasoning the model applies.
On limits, the facts here do not describe rate limits, quotas or unsupported input types beyond text, image and video. If your task is purely text and does not need multimodal input, tool calling or structured output, a simpler text only model may be enough. If you need output modalities other than text, this model does not provide them.
