qwen2.5-7b-instruct-1m

Qwen2.5-7B-Instruct-1M is a lightweight, long-context text instruction fine-tuned model from Alibaba’s Tongyi Qwen2.5 series. Its core positioning is as a “low-threshold, ultra-long-text processing assistant,” achieving 1 million-token-level context support with a lightweight parameter count, striking a balance between long-text capabilities and deployment costs.

• Ultra-long-context support: Natively supports up to 1,010,000 tokens as input and can generate texts of up to 8,192 tokens, easily handling ultra-long documents such as lengthy reports and codebases.
• Lightweight and efficient architecture: With a total of 7.62 billion parameters, it adopts a Transformer architecture combined with the GQA attention mechanism, integrating optimization techniques such as RoPE and SwiGLU.
• Full capability compatibility: It inherits extensive knowledge reserves, supports multiple languages (29+), and maintains strong foundational coding and mathematical abilities, while enhancing its capacity for long-text information extraction and logical coherence.
• Flexible application scenarios: Suitable for summarizing long documents, handling ultra-long conversations, and performing code audits; maintains stable accuracy within 262,144 tokens, and is adaptable to small-to-medium-sized hardware configurations.
