Model Card
Skylark Pro SC 250615 is a June 2025 snapshot of Skylark Pro, ByteDance's flagship chat model line offered through its BytePlus ModelArk platform. Skylark was ByteDance's original large language model family, made commercially available in 2023, and is the international counterpart to the Doubao models.
BytePlus positions Skylark Pro for complex question answering, summarization, creative writing, and role-play, and publishes a role creation guide for building persona-driven and multi-character chat. Role-play platforms such as Moescape have adopted it as a character chat model.
The model has a 128,000-token context window, and this deployment supports up to 12,000 output tokens per response. BytePlus documentation lists function calling and structured output among the Skylark Pro line's capabilities, with pricing of $0.40 per million input tokens and $1.60 per million output tokens.

More AI Models From ByteDance
Seed 2.1 Turbo
Seed 2.1 Turbo is the faster, lower-cost variant in ByteDance's Seed 2.1 family, a model line built for coding, long-horizon agent tasks, and multimodal understanding. It accepts text and image input, has a 256K context window, and supports function calling in an OpenAI-compatible format, so existing tool-use pipelines port over with little change. ByteDance positions it for high-volume production workloads such as agent pipelines, coding assistance, and document processing, and prices it at roughly half the cost of Seed 2.1 Pro. The company reports performance close to the Pro version and comparable to GPT-5.5 on coding and agent tasks, though no independently verified benchmark scores for Turbo were published at launch. Choose it when volume and cost drive the decision rather than peak capability; Seed 2.1 Pro remains the stronger option for the hardest tasks.
ChatSeed 2.0 Code
Seed 2.0 Code is ByteDance's dedicated coding model, released with the Seed 2.0 family in February 2026. It is built for agentic software work rather than autocomplete, with a stated focus on decomposing tasks into plans and revising those plans as work progresses, which suits multi-step feature implementation and bug diagnosis and repair. The model accepts image input alongside text, so it can read design mockups, screenshots, and charts and generate code from them. ByteDance cites high-precision text extraction and chart understanding as part of its multimodal perception. It has a 256K context window and up to 128K output tokens. ByteDance has not published benchmark scores for the Code variant. The same model powers coding in TRAE, ByteDance's AI IDE.
ChatSeed 2.0 Pro
Seed 2.0 Pro is the flagship model in ByteDance's Seed 2.0 series, built for long-chain reasoning, coding, and agent workflows. It accepts text, image, and video input and returns text. On benchmarks it scores 98.3 on AIME 2025, 87.8 on LiveCodeBench v6, and 76.5% on SWE-Bench Verified, with a Codeforces rating of 3020. For agent tasks it reaches 90.4 on tau2-Bench Retail and 77.3 on BrowseComp, and it ranks sixth on the LMArena leaderboard alongside GPT-5.2, Claude Opus 4.5, and Gemini 3 Pro. At $0.50 per million input tokens and $3 per million output tokens with a 256K context window, it is priced well below the frontier models it competes with, a fit for coding agents and complex multi-step workflows.
