ByteDance / seed-v2.1-turbo-uncensored

Overview

Seed v2.1 Turbo Uncensored is a multimodal large language model by ByteDance. It reads long text plus optional reference images, then produces a single text response. It’s built for agent-style work, where you need stable plans, code changes, and clear next steps.

What you can build

• Code assistance for debugging, refactors, and multi-file change plans
• Agent-style task breakdowns for office workflows, research, and project planning
• Image Q&A for screenshots, UI mockups, charts, and documents
• Structured writing like checklists, runbooks, incident reports, and test plans
• Long-context summarization across large notes, logs, or pasted documentation

Inputs

• A required task message in plain text. Explain goals, constraints, and desired output format.
• Optional reference images for visual understanding. You can attach multiple images in one request.
• Optional system-level instructions. Use them to set rules, tone, and output structure.
• Optional user and session identifiers. Provide them to keep conversation history across turns.
• Optional randomness controls. You can tune creativity with a temperature range of 0 to 2, and nucleus sampling with a top-p range of 0 to 1.
• Optional repetition controls. You can reduce loops or push topic diversity with frequency and presence penalties from -2 to 2.
• Optional output length control. You can cap the generated text up to 65,536 tokens.
• Optional reasoning depth controls. Choose a reasoning effort level from minimal to high, and select a thinking mode of enabled, disabled, or auto.

Outputs

• A text response that can include explanations, step-by-step plans, or code blocks.
• When you request structured formatting, the model typically follows strict layouts like JSON or bullet schemas.

Limitations

• This model returns text only. It does not generate images, audio, or video.
• Image understanding depends on input quality. Blurry photos, screenshots with tiny text, and scanned pages reduce accuracy.
• Very long prompts can still be truncated by provider limits, even with a 256K design target.
• The maximum generation length on this deployment is capped at 65,536 output tokens.
• It can hallucinate details. Verify factual claims, especially for legal, medical, or security topics.

Safety & compliance

• “Uncensored” typically means fewer built-in refusals. Behavior varies by provider and deployment.
• You must not use this model to generate or distribute illegal content.
• Don’t submit personal data you don’t have rights to share. Avoid passwords, API keys, and private identifiers.
• Never generate sexual content involving minors, non-consensual content, or instructions for wrongdoing.
• Add your own moderation and logging if you deploy outputs to end users.
