Grok 4.5 is a "Wow!" moment. 🤯
> Opus 4.8 & GPT-5.5 level on benchmarks
> Costs less than Sonnet 5
Is that real? Hard to believe.
Added Grok 4.5 as an implementer agent in fable-advisor. It replaces Sonnet 5.
Use Fable as the orchestrator and a combo of:
1. Grok 4.5
2. Opus 4.8
3. GPT-5.5
As implementer agents.
Uses the Grok Build CLI so if you log in with an X premium account you don't have to pay API fees.
this is f**king dangerous
someone just figured out how to get fable 5 reasoning in opus 4.8 with one prompt
you have less than 24 hours to set this up as this takes away 20% of your usage limit
here is how:
1) Paste the prompt and ask it to "make an operating manual"
2) Create a New Claude Project and "Add this .md in Project instructions
3) Use Opus 4.8 High/Max and now you have Fable 5 reasoning at 1/5th the price
save and bookmark it no matter what
Use Fable 5 as orchestrator and Opus + Codex to execute (to save fable usage):
Fable 5 (max reasoning) = orchestrator
Opus = deep reasoning subagent
Sonnet = mechanical work subagent
Codex = peer Sr. engineer, different perspective
Setup:
1. Set Fable 5 as your main model In Claude Code: /model → Fable 5 → reasoning /effort to max
2. Create 2 subagents with /agents In Claude Code:
deep-reasoner → pinned to opus "Use for reasoning-heavy phases, architecture, debugging complex issues, algorithm design. Think thoroughly, return a concise conclusion the orchestrator can act on."
fast-worker → pinned to sonnet "Use for mechanical tasks, boilerplate, tests, formatting, simple edits. Execute efficiently."
3. Add OpenAI's official Codex plugin (install codex cli in your computer first), In Claude Code type:
/plugin marketplace add openai/codex-plugin-cc
/plugin install codex@openai-codex
/codex:setup
4. Drop this in your CLAUDE.md in your folder:
## Orchestration workflow
You (Fable) are the orchestrator. Plan, decompose, synthesize.
Reasoning-heavy phases → deep-reasoner
Mechanical work → fast-worker
Codex (/codex:rescue --background) is a cracked engineer on par with deep-reasoner, from a different perspective. Treat as a peer, not a reviewer.
High-stakes decisions: task Opus + Codex on the same problem in parallel, synthesize the best of both, without showing either the other's answer. Keep your own context lean.
5. Then prompt Fable like a tech lead: "Goal: [what you want] Context: [files, constraints] You're the lead. Delegate reasoning to deep-reasoner, grunt work to fast-worker, fresh-perspective problems to Codex. Show me your plan first, then execute."
That's it.
