🔬 New AI Craft
1. smallcode: 4B Small Model Hits 87% Coding Benchmark
AI coding agent smallcode achieves 87% on SWE-bench-like tasks with just 4B active parameters, proving that large models aren't necessary for good code. Unlike conventional Agent Plan approaches, smallcode relies on architecture-level optimizations for small models — token budget management, search space pruning, and cache reuse — to match larger models while drastically cutting inference cost and deployment requirements.

2. Constraint Decay: The Fragility of LLM Agents in Backend Code Generation
A new arXiv paper reveals that LLM agents gradually "forget" initial constraints (DB schema, API specs, business rules) during long-sequence backend code generation, producing increasingly off-target results. While Agent Plan mode mitigates this partially through explicit step decomposition, the paper shows constraints still decay by 30%+ — pointing to a need for explicit constraint backtracking mechanisms in agent loops.

3. DeepSeek Reasonix — A Coding Agent Built for DeepSeek's Cache Architecture ♻️
An open-source terminal AI coding agent architected from the ground up around DeepSeek's prefix-cache mechanism for ultra-low token costs in long sessions. First-class MCP support, plan mode, cache-first loop. Unlike Cursor or Claude Code with DeepSeek as a backend, Reasonix is natively designed for DeepSeek's reasoning and caching characteristics. Reshared from 2026-04.
