·2026.07.16 01:42

Key point

InternScience has released Agents-A1, a 4B-scale model that maximizes agentic task performance.

Details

InternScience announced Agents-A1-4B, a model that maximizes reasoning ability as an agent instead of scaling up parameter size.

This model is based on Qwen3.5-4B, and despite being a small-scale model, it has proven strong performance across various benchmarks.

Key performance metrics:

  • GAIA (General AI Assistants): Scored 96.0, showing overwhelming agentic task performance compared to models of the same class
  • IFEval (Instruction Following): Scored 94.8, demonstrating high instruction-following capability
  • XBench-DS-2510: Scored 86.0, proving search and reasoning performance
  • SciCode: Scored 44.3, demonstrating efficiency in engineering and research tasks

The model's weights, including a GGUF format, have been released via Hugging Face, making it usable across a variety of environments.
