    蚂蚁百灵用 Ling-3.0-tiny 与 AReno 打通单机 Agentic RL 闭环

    蚂蚁百灵发布实践文章,介绍在 DGX Spark 上用本地后训练工具包 AReno 对 Ling-3.0-tiny 做 Agentic RL,以井字棋为最小验证任务跑通基线评测、Reward 定义、后训练与同环境复测四步闭环。实验使用 GSPO 训练 400 个 step,rollout/rewards_mean 从约 -0.5 升到 0.4 左右,response_len 降至约 850 tokens,复测中工具调用与落子选择更稳定。Ling-3.0-tiny 为 7.9B 总参数、1.3B 激活参数的混合推理模型,已开源 BF16、FP8 和 INT4 版本,AReno 提供 Docker 复现教程。
