Overview
An interactive command-line interface pattern for comparing multiple text generation strategies side-by-side with configurable parameters and real-time throughput measurement.
Description
The Interactive CLI pattern provides a REPL (Read-Eval-Print Loop) for exploring and comparing different inference strategies. It allows users to:
- Toggle individual generation methods on/off (speculative decoding, NASD, autoregressive baseline)
- Adjust generation parameters in real-time via slash commands (gamma, generation length, sampling strategy, n-gram storage type)
- Compare throughput across methods on the same prompt with the same random seed for reproducibility
- Visualize accepted/rejected draft tokens in debug mode
This pattern is valuable for researchers and practitioners who need to understand the performance characteristics of speculative decoding variants under different configurations. By providing side-by-side comparison with identical conditions, it enables fair benchmarking.
Usage
Use this pattern when building tools for interactively comparing inference strategies. The REPL approach allows rapid iteration: change parameters, try a prompt, observe results, adjust. The seed-fixing ensures reproducible comparisons across methods.
Theoretical Basis
The CLI comparison pattern follows a structured approach:
# Abstract CLI comparison pattern
class InferenceCLI:
def run():
load_models()
while True:
user_input = read_input()
if is_command(user_input):
update_configuration(user_input)
else:
set_seed(42) # reproducibility
for method in enabled_methods:
start = time()
output = method.generate(user_input)
elapsed = time() - start
throughput = len(output) / elapsed
display(method.name, output, throughput)
compare_throughputs()
Key design principles:
- Seed fixing: All methods use the same random seed per prompt for fair comparison
- Toggle-based: Each method can be independently enabled/disabled
- Real-time reconfiguration: Parameters can be changed between prompts without restarting
