Model Card
Dola Seed 2.1 Turbo is ByteDance's faster, lower-cost variant in the Seed 2.1 family, offered internationally through BytePlus's Model Ark platform. It accepts text, image, and video input, with a 256K context window and function calling for agent workflows.
On ByteDance's own benchmarks against Claude Opus 4.7, GPT-5.5, and Gemini 3.1 Pro, Turbo scores 89 on VideoMME for long video understanding and 79.2 on OVOBench for streaming video, ahead of Gemini 3.1 Pro's 86.7 and 64.1. It scores 88.0 on BeyondAIME reasoning, above Seed 2.1 Pro's 87.0. On knowledge tests like SuperGPQA it trails GPT-5.5 and Gemini. These are vendor-reported figures, not independently verified.
It suits high-volume API use such as video analysis, document processing, and agent pipelines, where cost and video handling matter more than peak coding scores.

Dola Seedream 5.0 Flash
Dola Seedream 5.0 Flash is ByteDance's fast, lower-cost image generation and editing model in the Seedream 5.0 family, offered here through BytePlus's ModelArk API under the "Dola" branding. It supports text-to-image and reference-guided editing with up to 10 input images, local edits targeted with point and bounding-box coordinates in the prompt, transparent-background output, and decomposition of an image into separate transparent layers. Output is 1K to 2K. BytePlus positions it as "faster image creation, stronger layouts, lower cost at scale." A third-party launch-day test reported 15 to 20 seconds per text-to-image request. It is the cheapest model in the Seedream 5.0 line, and Dola Seedream 5.0 Pro remains the better choice for photorealism and fine material detail. It suits high-volume work such as ad concepts, thumbnails, social visuals, and rapid design iteration.
ChatDeepSeek V4.1 Flash
DeepSeek V4.1 Flash is a Mixture-of-Experts chat model from DeepSeek, made available here through BytePlus's ModelArk platform. It succeeds DeepSeek V4 Flash, keeps a 1 million token context window, and accepts text and image input. In DeepSeek's own tests it scored 90.6 on Terminal-Bench 2.1, ahead of Claude Opus 5 (89.1) and GPT-5.6 Sol (88.8), and 74.2 on DeepSWE v1.1 versus 74.0 for Claude Opus 5. DeepSeek also reports it outperforming the larger V4 Pro. It supports tool calling and up to 384,000 output tokens, which suits coding agents, tool-calling pipelines, and long-context workloads at $0.30 per million input tokens and $1.20 per million output tokens.
ChatGLM-5.3 Flash
GLM-5.3 Flash is a multimodal Mixture-of-Experts model from Zhipu AI (Z.ai), available here through BytePlus's hosted API. It has 320 billion total parameters with 18 billion active per token, accepts text and image input, and supports a 1 million token context window. Z.ai reports 84.3 on Terminal-Bench 2.1 and 63.4 on DeepSWE v1.1 (GLM-5.2 scored 46.2). On Terminal-Bench 2.1 that is close to Claude Opus 4.8 at 85.0. Artificial Analysis gives it 57 on its Intelligence Index, three points behind the larger GLM-5.3. It is the lower-cost model in the GLM-5.3 family and supports tool calling. It suits coding agents and multi-step automation where per-token price matters.
