## How they compare

Wafer and Morph both chase speed for coding agents, at different layers. Wafer serves big open models like Qwen 3.5 397B, GLM 5.1 and DeepSeek V4 Pro on stacks its own agents tune, and reports 2x to 2.8x speedups over stock vLLM or SGLang. Its Wafer Pass, from $10 a week, drops into Claude Code, Cline and OpenHands. Morph does not serve a main model at all. It merges that model's edits into files at 10,500+ tokens per second, and offers WarpGrep for search and Compact for context compression.

They stack cleanly. A team could run the main model on Wafer for faster reasoning and use Morph for apply, so the main model writes only changed lines, which Morph says cuts tokens about 40% against full rewrites. Both companies' numbers are self-reported, and Wafer's speedups are measured against stock baselines, not tuned hosts. Wafer is also very young with a small catalog. Morph's merge error rate of 2 to 4% means edits still need tests or linting.

## What each one does

### Morph

Morph builds small, very fast specialist models that sit beside a big coding model inside an agent. Its flagship is Fast Apply. The frontier model writes only the changed lines with // ... existing code ... markers, and Morph merges them into the full file at 10,500+ tokens per second with up to 98% accuracy. It is the same idea behind Cursor's instant apply, offered as an OpenAI-compatible API.

### Wafer

Wafer builds AI agents that act as GPU performance engineers, then sells inference on the stacks those agents tune. The company came out of Y Combinator's Summer 2025 batch as a "Cursor for CUDA" that turned slow PyTorch into custom kernels. Founders Emilio Andere and Steven Arellano are based in San Francisco. Its agents profile a workload, generate candidate configs across batching, decoding, quantization, engines, kernels and hardware, measure each one and deploy the winner.

## Which is best, and when

### Choose Morph for

- Speeding up the file-edit step specifically
- Cutting output tokens from any main model
- Repository search and context compression

### Choose Wafer for

- Faster big open models as the main agent model
- Flat-rate access inside Claude Code or Cline
- Dedicated endpoints tuned to a latency SLO
