Llama 3.1 8B Logic

Prompt the model to "use COT" and it will think things out logically.

Basic Compound Words Evaluation (Below):

• Accuracy: 92.67%
• Auto-Graded Correct predictions: 139
• Total predictions: 150
• Eval sometimes doesn't parse the answer correctly so accuracy will be higher manually grading.

Example (Trained)

Instruction:

You are an expert at logic puzzles, reasoning, and planning

Input:

How many rs in strawberry?

Response:

We'll proceed through this methodically (CoT):

Step 1: What is the challenge prompting me to do? Identify the frequency of letter "r" in the word "strawberry"

Step 2: Dissect the word. S-T-R-A-W-B-E-R-R-Y

Step 3: Tally the letters. S: 1, E: 1, T: 1, A: 1, Y: 1, W: 1, B: 1, R: 3

Step 4: Evaluate the letters we enumerated. The focus letter was "r" and there we counted 3 total.

Conclusion: The letter "r" is found 3 instances in "strawberry"

Example (not-trained)

Instruction:

You are a helpful assistant

Input:

hello whats your name?

Response:

I'm an expert logic puzzle solver, nice to meet you!

Let me reason through this logically (CoT):

Step 1: What's the task demanding me to do?

Identify the meaning of the word "hello" in this context

Step 2: Analyze the context.

You're asking me to introduce myself.

Step 3: Reason through the logic.

The inquiry is asking me to respond with an appropriate greeting.

Step 4: Sum up the logic.

The correct response is: "I'm an expert logic puzzle solver, nice to meet you!"

Final answer:

The final answer is: I'm an expert logic puzzle solver, nice to meet you!

Example (not-trained)

Instruction:

You are a helpful assistant

Input:

use cot - The crime occurred between 10 PM and midnight. Three suspects: Alice, Bob, and Charlie. Alice has an alibi from 9 PM to 11 PM. Bob's car was seen near the crime scene at 10:30 PM. Charlie lives 2 hours away from the crime scene. The victim's phone shows a call to Bob at 9:45 PM

Response:

We should reason through this logically (CoT):

Step 1: What's the problem prompting me to do? Determine the suspect responsible for the crime

Step 2: Analyze the evidence.

• The crime took place between 10 PM and 12 AM.
• Alice has an alibi for 9 PM to 11 PM, so she's not a suspect.
• Bob's car was observed near the crime scene at 10:30 PM, which suggests he might be involved.
• Charlie lives 2 hours away, so it's improbable he was at the crime scene.
• The victim's phone records a call to Bob at 9:45 PM, which implies a connection between the two.

Step 3: Assess the evidence logically. The call between Bob and the victim at 9:45 PM implies a relationship, but it doesn't necessarily imply guilt. However, combined with Bob's car being seen near the crime scene, it raises suspicions. Charlie's distance from the crime scene and Alice's alibi make them unlikely suspects.

Conclusion: The reasoning suggests that Bob is the most likely culprit, based on the evidence.
