RAG over OCR — Complete Research & Model Strategy (Single-File Edition)

Consolidated Aug 2026. Parts 1–7: the deep research report. Parts 8–10: follow-up research on model strategy (OpenRouter-first/local-later), the live OpenRouter catalog + MCP, and the final paid open-weight stack.

⚠️ Reading order for model picks: later parts supersede earlier ones. Part 10 (paid open stack) is the CURRENT recommendation; generation-model picks in Parts 1–8 (Qwen3-235B / DeepSeek-V3.2 era) are retained for the evidence trail but superseded by the Kimi K3 / GLM-5.2 / DeepSeek-V4 wave. Part 11 (Aug 14 re-verification) confirms the Part 10 stack and tracks the GLM-5.5 watch.

Using Codex CLI OAuth Tokens as a Free OpenAI Backend (and why it's risky)

A writeup of the technique where you reuse the OAuth token that the Codex CLI stores after "Sign in with ChatGPT" to make raw LLM calls from your backend — so requests bill against your ChatGPT subscription's included usage instead of consuming pay-as-you-go API credits.

⚠️ This is an unofficial, ToS-gray-area hack. Read the risks section before building anything on it.

Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!
