LLM and Image Pipeline Internals

OpenRouter Client Behavior​

OpenRouter requests include:

  • timeout: 45s per attempt
  • retries: up to 3 attempts
  • retryable status codes: 408, 409, 429, 5xx
  • transient network retry handling

Structured requests support parse callbacks for runtime validation.

Plan and Prompt Validation​

Ideon validates:

  • article plans (articleSchema constraints)
  • image prompt payloads (prompt required)
  • run configuration via Zod schema defaults and constraints

Invalid provider output fails fast with actionable errors.

Section Normalization​

Generated text is normalized by:

  • trimming whitespace
  • removing markdown fences when present
  • rejecting empty output sections

Prompt System Composition​

Prompt composition now includes layered directives:

  • shared writing framework (structure, information density, specificity, rhythm, scannability, active voice, storytelling discipline, authenticity filter)
  • style overlay (professional, friendly, technical, academic, opinionated, storytelling)
  • content-type/channel directives (article, x-thread, x-post, linkedin-post, etc.)

Article planning prompts also include adaptive persuasion guidance so the planner can choose AIDA, PAS, or BAB based on audience and objective fit.

For multi-target runs, article outputs may be used as anchor context for social/channel outputs.

Non-Article Output Path​

  • Non-article content types are generated in single-shot prompts.
  • This path runs in the output stage and does not require section-based generation.
  • For no-article runs, planning/sections/image stages are skipped.

Image Rendering Path​

  1. Build image slots from plan (cover + inline)
  2. Expand each slot description to final prompt
  3. Build Replicate input from model registry and sanitized overrides
  4. Execute model and normalize output bytes
  5. Write image files and compute markdown-relative paths

Dry-Run Behavior​

Dry-run bypasses provider calls but exercises orchestration:

  • deterministic synthetic plan and sections
  • placeholder asset files
  • normal markdown assembly
