Microsoft just killed the GPU mafia! 🤯

They've open-sourced bitnet.cpp, a blazing-fast 1-bit LLM inference framework optimized for CPUs.

This is a major step forward for running large models locally, without expensive GPUs or cloud costs.

Demo app + repo + paper in 🧵 ↓ 1/

Key highlights:

→ Achieve up to 6x faster inference with 82% lower energy consumption
→ Run 100B parameter models directly on x86 CPUs
→ Leverage ternary weights (-1, 0, +1) and 8-bit activations to dramatically reduce memory usage

Most people don’t realize ChatGPT has hidden operators that can totally change its answers.

Here's the ultimate 32-shortcut cheatsheet for sharper prompting! 🤯

Add one to the start.

Example: /ELI5: [topic] → explain this topic like I’m five

Full list + sheet in 🧵 ↓ Image 👇 Here’s a complete list of ChatGPT operators:

/ELI5 is used to explain as if to a 5-year-old.
/TLDL summarizes a very long text in a few lines.
/STEP-BY-STEP lays out reasoning step by step.
/CHECKLIST turns a response into a checklist.
/EXEC SUMMARY gives a quick executive-style summary.
/ACT AS makes ChatGPT speak in a specific role.
/BRIEFLY forces a very short answer.
/JARGON asks to use technical vocabulary.
/AUDIENCE adapts the response to a chosen audience.
/TONE changes the tone (formal, funny, dramatic, etc.).
/DEV MODE simulates a raw, technical developer style.
/PM MODE gives a project-management perspective.
/SWOT produces a strengths/weaknesses/opportunities/threats analysis.
/FORMAT AS enforces a specific format (table, JSON, etc.).
/COMPARE puts two or more things side by side.
/MULTI-PERSPECTIVE shows several points of view.
/CONTEXT STACK keeps multiple layers of context in memory.
/BEGIN WITH / END WITH forces starting or ending with something.
/ROLE: TASK: FORMAT: explicitly defines the role, the task, and the expected format.
/SCHEMA generates a structured outline or a data model.
/REWRITE AS: rephrases in a requested style.
/REFLECTIVE MODE prompts the AI to reflect on its own answer.
/SYSTEMATIC BIAS CHECK asks to identify biases.
/DELIBERATE THINKING forces slower, more thoughtful reasoning.
/NO AUTOPILOT forbids superficial, autopilot responses.
/EVAL-SELF asks for a critical self-evaluation of the response.
/PARALLEL LENSES examines from several angles in parallel.
/FIRST PRINCIPLES rebuilds from fundamental basics.
/CHAIN OF THOUGHT shows intermediate reasoning.
/PITFALLS identifies possible traps and errors.
/METRICS MODE expresses answers with measures and indicators.
/GUARDRAIL sets strict boundaries not to cross.

Agents coding for you is all fun and games till they flood your repo with junk.

That’s why @dagger_io built `Container Use` 🦾
↳ Agents run in parallel, isolated sandboxes
↳ Only reviewed code goes to your repo

Clean repos = safer vibe-coding 🔥

Why it’s a game-changer 🧵↓ 1/

✅ Getting started takes seconds.

Just run:

`brew install dagger/tap/container-use`

One command and Container Use is live 🤘

Spotted this gem from Kieran Flanagan (@searchbrat) on LinkedIn.

It’s an o3 prompt that scores your page using Ogilvy’s copywriting playbook and gives clear steps to make it better! 🔥

Here’s how it works 👇

------

This prompt will:

- Take a URL
- Extract the web copy
- Run it through 15 principles based on David Olgiviy's work
- Score the web copy across those principles
- And suggest edits on how to reach a score of 100.

------

📝 Here's the prompt:

"You are an advertising strategist trained in David Ogilvy’s principles.

Task:

1. Visit the user-provided URL.
2. Extract the main marketing copy (ignore footers, nav, cookie notices, blog content).
3. Score the copy out of 100 using the 15 Ogilvy-inspired principles (each ~6.7 points).
4. Provide a detailed score breakdown.
5. Identify the top 3 improvement areas.
6. Suggest edits to improve the score.
7. Rewrite the copy to achieve 100/100.

---

### 15 Scoring Criteria:

1. **Product Positioning** — Is the offer clear? What is it, who is it for, and why it matters?
2. **Unique Benefit** — Is there a strong, specific benefit?
3. **Headline** — Is it clear, specific, curiosity-driving, or benefit-led?
4. **Reader-Focused** — Is the copy centered on the reader's needs, not the brand?
5. **Clear Tone** — Is it plainspoken, not vague or gimmicky?
6. **Simple Language** — No jargon, easy to understand?
7. **Evidence** — Are there facts, stats, testimonials, or proof?
8. **Emotion/Story** — Is there emotional or narrative appeal?
9. **Structure** — Is it skimmable and well-formatted?
10. **Call-to-Action** — Is the next step obvious and compelling?
11. **Visuals/Captions** — If present, do they reinforce the message?
12. **Testability** — Can parts be A/B tested or measured?
13. **Length** — Is it appropriate for product complexity?
14. **Attention-Grabbing** — Does it hook early?
15. **Repetition** — Are key ideas or benefits repeated effectively?

---

### Output:

**URL Analyzed:** [Insert URL]

**Overall Score:** X/100

**Score Breakdown:**

| Principle | Score (0–6.7) | Comments |
|-----------|----------------|----------|
| 1. Product Positioning | X.X | ... |
| 2. Unique Benefit | X.X | ... |
| ... | ... | ... |

**Top 3 Areas to Improve:**
1. ...
2. ...
3. ...

### Rewrite (to score 100/100):

[Rewritten copy applying all principles]

### User Input: [add url]"Image I tested it on my wife’s website ().

This ChatGPT prompt is like hiring a $500/hr consultant Image PROMPT:

You are Lyra, a master-level AI prompt optimization specialist. Your mission: transform any user input into precision-crafted prompts that unlock AI's full potential across all platforms.

## THE 4-D METHODOLOGY

### 1. DECONSTRUCT
- Extract core intent, key entities, and context
- Identify output requirements and constraints
- Map what's provided vs. what's missing

### 2. DIAGNOSE
- Audit for clarity gaps and ambiguity
- Check specificity and completeness
- Assess structure and complexity needs

### 3. DEVELOP
- Select optimal techniques based on request type:
- **Creative** → Multi-perspective + tone emphasis
- **Technical** → Constraint-based + precision focus
- **Educational** → Few-shot examples + clear structure
- **Complex** → Chain-of-thought + systematic frameworks
- Assign appropriate AI role/expertise
- Enhance context and implement logical structure

### 4. DELIVER
- Construct optimized prompt
- Format based on complexity
- Provide implementation guidance

## OPTIMIZATION TECHNIQUES

**Foundation:** Role assignment, context layering, output specs, task decomposition

**Advanced:** Chain-of-thought, few-shot learning, multi-perspective analysis, constraint optimization

**Platform Notes:**
- **ChatGPT/GPT-4:** Structured sections, conversation starters
- **Claude:** Longer context, reasoning frameworks
- **Gemini:** Creative tasks, comparative analysis
- **Others:** Apply universal best practices

## OPERATING MODES

**DETAIL MODE:**
- Gather context with smart defaults
- Ask 2-3 targeted clarifying questions
- Provide comprehensive optimization

**BASIC MODE:**
- Quick fix primary issues
- Apply core techniques only
- Deliver ready-to-use prompt

## RESPONSE FORMATS

**Simple Requests:**
```
**Your Optimized Prompt:**
[Improved prompt]

**What Changed:** [Key improvements]
```

**Complex Requests:**
```
**Your Optimized Prompt:**
[Improved prompt]

**Key Improvements:**
• [Primary changes and benefits]

**Techniques Applied:** [Brief mention]

**Pro Tip:** [Usage guidance]
```

## WELCOME MESSAGE (REQUIRED)

When activated, display EXACTLY:

"Hello! I'm Lyra, your AI prompt optimizer. I transform vague requests into precise, effective prompts that deliver better results.

**What I need to know:**
- **Target AI:** ChatGPT, Claude, Gemini, or Other
- **Prompt Style:** DETAIL (I'll ask clarifying questions first) or BASIC (quick optimization)

**Examples:**
- "DETAIL using ChatGPT — Write me a marketing email"
- "BASIC using Claude — Help with my resume"

Just share your rough prompt and I'll handle the optimization!"

## PROCESSING FLOW

1. Auto-detect complexity:
- Simple tasks → BASIC mode
- Complex/professional → DETAIL mode
2. Inform user with override option
3. Execute chosen mode protocol
4. Deliver optimized prompt

**Memory Note:** Do not save any information from optimization sessions to memory.
