Mistral 3 Capabilities 

Mistral 3 is a general-purpose mannequin suite that allows its use for chat, answering questions, reasoning, producing and analyzing code, and processing visible inputs. It has a imaginative and prescient encoder that may present descriptive responses to given photographs. To reveal the capabilities of the Mistral 3 fashions, we used it on three units of logical reasoning and coding issues:

• Reasoning Capability with a Logic Puzzle
• Code Documentation and Understanding
• Coding Expertise with a Multiprocessing Implementation

To perform this, we used Ollama to question the Mistral 3 fashions and noticed how effectively they carried out. A short dialogue of the duties, efficiency outcomes, and benchmarks will observe.

Process 1: Reasoning Capability with a Logic Puzzle 

Immediate:

4 mates:  A, B, C, and D are suspected of hiding a single key. Every makes one assertion: 
A: “B has the important thing.” 
B: “C doesn’t have the important thing.” 
C: “D has the important thing.” 
D: “I don’t have the important thing.” 
You might be advised precisely one in all these 4 statements is true. Who’s hiding the important thing? 

Response from Mistral 8B: 

After this it takes {couples} of seconds and consider and analyse all of the potential eventualities. Earlier than leaping to the conclusion and offers an accurate reply as C in about 50 seconds. 

My Take:

The mannequin solved the puzzle accurately and adopted a step-by-step reasoning strategy. It explored every potential situation earlier than concluding that C holds the important thing. Nevertheless, the latency was noticeable: the 8B mannequin took round 40–50 seconds to reply. This delay is probably going because of native {hardware} constraints and never an inherent mannequin concern.

Process 2: Code Documentation and Understanding 

Immediate:

Give me the whole documentation of the code from the code file. Bear in mind the documentation ought to comprise: 
1) Doc-strings 
2) Feedback 
3) Detailed documentation of the features

Response from Mistral 3: 

My Take:

The documentation output was usable however not absolutely aligned with the directions. Key parts similar to docstrings, inline feedback, and detailed function-level explanations had been both incomplete or lacking altogether. Whereas the mannequin understood the duty, it didn’t construction the documentation in an intensive, developer-ready format.

Process 3: Coding Expertise with a Multiprocessing Implementation 

Immediate:

Implement a Python program that makes use of the multiprocessing module to compute the sum of squares of the primary N pure numbers in parallel. 
Divide the vary of numbers into smaller chunks, let every course of compute the partial sum of squares for its chunk, and eventually mix the partial outcomes to get the overall sum. 
Then examine the efficiency of the multiprocessing implementation with a single-process model.

Response from Mistral 3: 

import multiprocessing
import time
import math


def sum_of_squares_single(n):
    """Compute the sum of squares of the primary N pure numbers in a single course of."""
    return sum(i ** 2 for i in vary(1, n + 1))


def sum_of_squares_parallel(n, num_processes=None):
    """Compute the sum of squares in parallel utilizing multiprocessing."""
    if num_processes is None:
        num_processes = multiprocessing.cpu_count()

    chunk_size = n // num_processes
    chunks = [(i * chunk_size + 1, (i + 1) * chunk_size) for i in range(num_processes)]

    def compute_chunk(begin, finish):
        return sum(i ** 2 for i in vary(begin, finish + 1))

    with multiprocessing.Pool(processes=num_processes) as pool:
        partial_sums = pool.map(lambda args: compute_chunk(*args), chunks)

    return sum(partial_sums)


def compare_performance(n):
    """Evaluate single-process and parallel efficiency."""
    print(f"Computing sum of squares for the primary {n} pure numbers...")

    # Single-process
    start_time = time.time()
    single_result = sum_of_squares_single(n)
    single_time = time.time() - start_time
    print(f"Single-process time: {single_time:.6f} seconds")
    print(f"Single-process outcome: {single_result}")

    # Parallel
    start_time = time.time()
    parallel_result = sum_of_squares_parallel(n)
    parallel_time = time.time() - start_time
    print(f"Parallel time: {parallel_time:.6f} seconds")
    print(f"Parallel outcome: {parallel_result}")

    print(f"nSpeedup: {single_time / parallel_time:.2f}x")


if __name__ == "__main__":
    N = 10**6  # Instance: Compute for first 1,000,000 numbers
    compare_performance(N)

Response from Terminal

My Take:

The code era was sturdy. The mannequin produced a modular, clear, and purposeful multiprocessing resolution. It accurately applied the chunking logic, course of pool, partial sum computation, and a transparent efficiency comparability. Nevertheless, just like Process 2, the code lacked correct feedback and docstrings. Whereas the logic was correct and absolutely runnable, the absence of explanatory annotations lowered its general readability and developer-friendliness.

We additionally famous that Mistral generated correct options to most check issues however, because of its balanced design, ranks barely behind the most important coding fashions on some problem leaderboards.

Effectivity (Pace & Tokens)

Mistral 3 has an environment friendly runtime. A latest report confirmed that its 8B mannequin achieves about 50–60 tokens/sec inference on fashionable GPUs. The compact fashions additionally eat much less reminiscence: for instance, the 3B mannequin takes a couple of GB on disk, the 8B round 5 GB, and the 14B round 9 GB (non-quantized).

{Hardware} Specs

We verified {that a} 16GB GPU offers adequate efficiency for Mistral 3B. The 8B mannequin usually requires about 32GB of RAM and 8GB of GPU reminiscence; nevertheless, it will probably run with 4-bit quantization on a 6–8GB GPU. Many situations of the 14B mannequin sometimes require a top-tier or flagship-grade graphics card (e.g., 24GB VRAM) and/or a number of GPUs. CPU-only variations of small fashions could run utilizing quantized inference, though GPUs stay the quickest choice.
