Vector Database vs Knowledge Graph for LLMs
A practical guide comparing vector databases and knowledge graphs as storage backends for LLM applications. The article explains that vector databases (e.g., Qdrant, pgvector, Pinecone) store embeddings and excel at semantic similarity queries, while knowledge graphs (e.g., Neo4j, RDF stores) model entities and relationships and support exact, multi-hop relational queries. The author argues most real-world LLM systems need a hybrid: vectors for retrieval and graphs for precise reasoning and auditability (a pattern exemplified by Microsoft’s GraphRAG). Tool-level trade-offs, operational costs, and a four-question decision rule are provided to help teams choose the right architecture for their queries.
- Vector databases store high-dimensional embeddings and are optimized for semantic similarity (examples: Qdrant, pgvector, Pinecone, Milvus, Weaviate, Chroma).
- Knowledge graphs store entities and relationships as first-class citizens and support exact traversals and multi-hop queries using languages like Cypher or SPARQL (examples: Neo4j, RDF stores).
- The author has deployed both approaches in production: vector solutions (Qdrant and pgvector) and Neo4j for graph workloads.

Configure LiteLLM as Codex Model Provider
A developer guide demonstrating how to route Codex to use LiteLLM as a custom model provider. The post explains exposing a LiteLLM API key as an OS environment variable, updating Codex's .codex/config.toml to set model_provider to 'litellm' and add provider-specific fields (base_url, env_key, wire_api, streaming options), setting optional custom HTTP headers, and noting that session models are fixed at session creation. The author also advises verifying usage via LiteLLM dashboard logs and links to LiteLLM and Codex documentation for reference.
- Author Julia Shevchenko published a how-to on dev.to on 2026-08-28 about configuring LiteLLM as a gateway for Codex.
- LiteLLM exposes an OpenAI-compatible interface and can act as a gateway for LLMs.
- Required steps include setting LITELLM_API_KEY as an OS environment variable and updating .codex/config.toml to set model_provider = "litellm" and provider-specific settings (base_url, env_key, wire_api, streaming options).

Python 3.15 Release Candidate and Highlights
Python 3.15 has reached Release Candidate 1 with the final release expected on October 1, 2026. Key changes include lazy imports for faster startup, UTF-8 as the default encoding, a built-in immutable mapping (frozendict-style), continued JIT compiler improvements with early benchmarks (roughly 8–9% on Linux and larger gains on Apple Silicon), and a new low-overhead sampling profiler called Tachyon. Free-threaded (no-GIL) builds remain opt-in but gain maturity and improved ABI support for C extensions. The release focuses on performance, tooling, and developer experience rather than major language syntax changes.
- Python 3.15 has reached Release Candidate 1; final release expected on 2026-10-01.
- Python 3.15 introduces lazy imports to reduce startup time by loading modules only when needed.
- UTF-8 becomes the default encoding in Python 3.15.
