Speculative Decoding

Skill Verified Active

Accelerate LLM inference using speculative decoding, Medusa multiple heads, and lookahead decoding techniques. Use when optimizing inference speed (1.5-3.6× speedup), reducing latency for real-time applications, or deploying models with limited compute. Covers draft models, tree-based attention, Jacobi iteration, parallel token generation, and production deployment strategies.

Purpose

To enable users to significantly speed up LLM inference and reduce latency by leveraging advanced decoding techniques like speculative decoding, Medusa, and Lookahead decoding.

Features

  • Accelerates LLM inference using speculative decoding
  • Implements Medusa's multiple decoding heads for faster generation
  • Utilizes Lookahead Decoding (Jacobi iteration) for parallel token generation
  • Provides code examples for integration with Transformers and vLLM
  • Details training methods and hyperparameter tuning for Medusa and Lookahead

Use Cases

  • Optimizing LLM inference speed (1.5-3.6x speedup)
  • Reducing latency for real-time applications (chatbots, code generation)
  • Deploying models efficiently on limited compute hardware
  • Generating text faster without quality loss

Non-Goals

  • Model architecture design beyond adding decoding heads
  • Training large language models from scratch
  • Providing inference servers (focus is on decoding techniques)
  • Handling tasks outside of LLM inference optimization

Practical Utility

  • info:Edge casesThe SKILL.md discusses hyperparameter tuning and method selection, which touches on optimizing performance but does not explicitly list failure modes with recovery steps.

Execution

  • info:Pinned dependenciesDependencies are listed, but not explicitly pinned with lockfiles in the SKILL.md, which could lead to issues if newer versions break compatibility.

MongoDB Connection Optimizer

100

Optimize MongoDB client connection configuration (pools, timeouts, patterns) for any supported driver language. Use this skill when working/updating/reviewing on functions that instantiate or configure a MongoDB client (eg, when calling `connect()`), configuring connection pools, troubleshooting connection errors (ECONNREFUSED, timeouts, pool exhaustion), optimizing performance issues related to connections. This includes scenarios like building serverless functions with MongoDB, creating API endpoints that use MongoDB, optimizing high-traffic MongoDB applications, creating long-running tasks and concurrency, or debugging connection-related failures.
