Arcana: Embeddable RAG for Elixir/Phoenix
Everything I've learned building RAG systems, packaged into one Elixir library. Hybrid search, agentic pipelines, GraphRAG, all running on your existing Ecto Repo and pgvector.
Stephen: ColBERT-Style Neural Retrieval for Elixir
ColBERT-style late interaction retrieval for Elixir. Per-token embeddings and MaxSim scoring for more precise search than single-vector approaches.
Vibe, Agentic, Organic: The Three Ways to Code in 2026
Everyone's an AI-assisted developer now. But the range of what that means is absurd.
Elixir/BEAM Doesn't Solve Everything for AI Agents. Addressing the Criticisms.
Addressing the three most valid criticisms of using Elixir and the BEAM for AI agents.
Alike: Semantic Similarity Testing with the Wave Operator
Test LLM outputs by meaning, not by characters. A wave operator for semantic similarity assertions in Elixir, powered by local embeddings.
Your Agent Framework Is Just a Bad Clone of Elixir: Concurrency Lessons from Telecom to AI
Python and JavaScript/TypeScript AI frameworks are reinventing what telecom solved in 1986. What 40 years of production-grade concurrency teaches us about building AI agents.
