Deepseek just gave away the thing everyone else charges $200 a month for.
Your feed calls it an open source coding agent. It is not. They open sourced the harness. The harness is everything around the model: which tools it gets, what loop it runs in, what enters context, what
Autonomous agents fail when prompts get too short (Brevity Bias) or when iterative memory rewrites wipe out accumulated experience (Context Collapse).
Stanford and SambaNova published Agentic Context Engineering (ACE, ICLR 2026) to solve this without updating model weights.
