Elon wasn’t messing around. Grok 4.5 is indeed Opus level, faster, and cheaper.
Never thought I’d live to see this day but OpenAI and Anthropic have some serious competition now.
🚨GROK 4.5 IS ~17x CHEAPER THAN OPUS 4.8 ON REAL TASKS
>Grok 4.5: $2 input / $6 output
>Opus 4.8: $5 input / $25 output
4x cheaper per token AND solves the same task in 4.2x fewer tokens
If you dont know, you can use your Codex subscription inside Claude Code.
That means Fable 5 can call GPT 5.5 + 10 subagents to work together.
This will save you atleast 60% of your Fable 5 token consumption.
You just need to setup once. Here's how:
Step 1: Open Claude Code and install the Codex plugin
/plugin marketplace add openai/codex-plugin-cc
/plugin install codex@openai-codex
/reload-plugins
Step 2: Tell Fable 5 to finish the setup
Paste this prompt:
"Set up Codex inside this Claude Code environment. Use the official OpenAI Codex plugin that was just installed. Run /codex:setup. If Codex CLI is missing, install it. If Codex is installed but not authenticated, ask me to authenticate with my ChatGPT account. After auth is complete, verify that Codex works from inside Claude Code. Then confirm that the codex:codex-rescue sub-agent is available. Do not change any project code during setup."
Step 3: Authentication
Fable 5 will trigger the Codex setup.
You authenticate your ChatGPT/Codex account once.
After that, Codex runs from inside Claude Code using your Codex subscription.
Step 4: Tell Fable 5 how to delegate work
Paste this prompt:
"From now on, use this workflow:
You are the orchestrator.
> Use Fable 5 for planning, repo understanding, architecture decisions, task decomposition, and final review.
> Use codex-rescue as the executor when a task needs heavy implementation, debugging, test fixing, refactoring, or multi-file code edits.
When delegating to Codex, use /codex:rescue.
Prefer GPT 5.5 (xtra high) as the go to Codex model.
Keep Codex tasks focused and specific.
After Codex finishes, inspect the result yourself before accepting it.
Do not blindly trust Codex output."
Pro Tips:
1. Turn this into a skill (i named it Fable-GPT) and call that skill at the start of the session.
2. Use skill + goal to get the heavy tasks done. Goals are best for long horizon tasks.
3. If you're on Codex 20x pro plan, you can use subagents. I use 5-7 agents at one time and never hit 5-hour limit.
4. Context rot is real so clear the conversation after 4 compactions. Use /handoff skill to preserve context.
New CursorBench results just dropped and Grok 4.5 is the story.
#3 overall at 66.7%. Right behind Fable 5 Max at 70.5%.
Now look at the cost column.
Fable 5 Max: $17.32 per task
Grok 4.5 High: $1.51 per task
That is Fable level performance at roughly 1/10th the cost.
And it beats Fable 5 High and Opus 4.8 Max outright.
The intelligence war just became a price war.
How much do Chinese models cut your API bill? 🇨🇳
WITH THE SAME OUTPUT!!!
US frontier model → chinese open model, cost to do one task:
[ reasoning brain ]
Claude Opus 4.8 → DeepSeek V4 Pro
$1.80 → $0.04 per task
~45x cheaper, and it's tied with Opus on SWE-bench (80.6 vs 80.8)
[ code generation ]
GPT-5.5 → GLM 5.2
$1.03 → $0.48 per task
~2x cheaper AND it beats GPT-5.5 on long-horizon coding
[ agents + tool calling ]
Claude Sonnet 5 → Kimi K2.7
$2.29 → ~$0.31 per task
~7x cheaper, best agentic stability of the open models
[ bulk / high volume ]
Gemini 3.5 Flash → DeepSeek V4 Flash
$0.59 → $0.02 per task
~30x cheaper, plenty for extraction, classification, drafts
the tradeoff:
> coding + agents.. near parity or better
> hardest reasoning + world knowledge.. ~10-15% behind
> your bill.. down 2-45x depending on the task
one catch: Qwen3.7 Max is chinese but priced like frontier ($1.06/task).. cheap isn't automatic
route each task to the model that wins it:
code → GLM..
agents → Kimi..
value reasoning → DeepSeek..
bulk → DeepSeek Flash
keep a US frontier model for the 10% that truly needs it
hello internet stranger,
read this book 2 times
would love to talk about this book ... if you are junior or just starting with this book just for interview purposes go through chapter 3, 5, 6, 8 and 9 thoroughly although you will find the book a little hard for the first but sticking with it will be worthwhile
If you read it really carefully and very slowly, the content is fantastic and can’t be faulted.
I have ordered the second addition but I had to cancel my order on halfway will see next time :)
‼️ BREAKING: Anthropic has embedded hidden spyware-like code in Claude Code that covertly targets Chinese users. It then sends information regarding every user by injecting it into their prompt message.
Claude Code is sending info like timezone, proxy and possible AI Lab connections into the system prompt in ways Chinese users can't notice.
A coding agent with repo and command permissions should not silently hide routing metadata inside prompts. This is a serious breach of user trust.
Claude's official chat export is broken.
It emails you a link. The link doesn't work. You try again. Still nothing.
So I built the thing that should've existed.
