Speculative decoding: when and why it actually speeds up inference
Here's a real, runnable config that uses EAGLE for offline batched generation. It's straight from the vLLM repo's eagle.md example:

Spec-Driven Development with OpenSpec
Say I'm tinkering with deathclaw-alpha, a little self-hosted AI assistant I run at home on OpenClaw and a local vLLM instance:

Gemma 4 dense by default: why your local agent doesn't want the MoE
Compilation is cleaner on dense. llama.cpp, MLX, and vLLM all support both, but the dense path has had more attention. Fewer corner cases in expert routing, GQA, and KV layout interactions. If you've ever had a custom kernel mis-handle expert dispatch, you know.

What GenAI Actually Costs in Production
The compute is real, and the compute is not the part that decides. Self-hosting means picking and operating a serving framework — vLLM and Text Generation Inference are the dominant choices in 2026 — and picking and operating the orchestration around it: Kubernetes or a comparable runtime, container registries, model artifact storage, an evaluation harness that runs on every model update, an on-call rotation that knows what to do when an inference replica wedges, a release-gating process for new model versions, and a documented procedure for the cases when an OSS model is deprecated by its publisher and needs to be rotated to a successor.

Inside vLLM's CPU backend: a new contributor's notes
Most of the public technical writing about vLLM focuses on its GPU-side innovations — PagedAttention, continuous batching, the V1 engine. Less has been written about the CPU backend, which is where I spent the last couple of weeks: building vLLM from source, working through some rough edges, and shipping a small PR that clarifies three confusing error messages.

Accelerating Gemma 4: faster inference with multi-token prediction drafters

Stable Diffusion 3.0 and Llama 4: The RAG pipelines You Didn’t Know You Needed
Llama 4-70B-Instruct requires ~140GB of GPU memory in full precision (FP16), which means you need 2x A100 80GB instances per replica, costing ~$16/hour on AWS. Our benchmarks show 4-bit quantization using bitsandbytes (https://github.com/TimDettmers/bitsandbytes) reduces memory usage to ~35GB, allowing a single A100 40GB instance to run the model at 1/4 the cost. We tested 4-bit, 8-bit, and FP16 quantization across 10,000 queries and found 4-bit quantization has only a 1.2% drop in response accuracy for RAG use cases, which is negligible for most production applications. Avoid 8-bit quantization unless you have strict accuracy requirements: it only reduces memory usage by 40% vs 4-bit’s 75%, making it a poor cost-accuracy tradeoff. For high-throughput pipelines, use vLLM (https://github.com/vllm-project/vllm) instead of the default HuggingFace generate method: vLLM’s PagedAttention reduces latency by 3x for batch sizes over 8, and supports continuous batching for dynamic query loads. We saw throughput jump from 14 queries/sec to 89 queries/sec after switching to vLLM for Llama 4 inference. Always test quantization with your specific dataset: medical and legal RAG pipelines may see higher accuracy drops, so we recommend a 2-week A/B test before rolling out quantized models to production.

LLM on EKS: Serving with vLLM
This post is a small step in that direction: serving an LLM using vLLM, deployed on Amazon EKS, provisioned the infra using AWS CDK, and wrapped into a simple chatbot using Streamlit.
