Amazon Bedrock vs Wafer: key differences
Wafer is a very young company that sells inference on stacks its own agents tune. Those agents test configs across batching, decoding, quantization, engines, kernels and hardware, deploy the winner and keep re-tuning on NVIDIA or AMD. Wafer reports Qwen 3.5 397B at 2.8x stock SGLang and GLM 5.1 and DeepSeek V4 Pro at 2x a vLLM baseline. Its Wafer Pass is a flat subscription from $10 a week for coding harnesses. Bedrock serves 100+ closed and open models under AWS security, billed per token or through provisioned throughput.
Wafer fits developers who want large open models at interactive speed in Claude Code or Cline, and teams with a strict latency SLO but no kernel engineers. Its catalog is small, and its speedups are measured against stock baselines, not tuned hosts. Bedrock fits enterprises that need frontier closed models, governance, Guardrails and a managed agent runtime, and it has the track record Wafer lacks. The price of that is markups of 20 to 35% on most models.
What Amazon Bedrock and Wafer do
Amazon Bedrock
Amazon Bedrock is AWS's managed model service and has become the default AI control plane for many enterprises. One API reaches 100+ models from 18+ providers, including Anthropic's Claude family, Meta, Mistral, DeepSeek, Amazon's own Nova models, and, since an April 2026 partnership expansion, OpenAI models up to GPT-6 Astra. Switching models is usually just a new model ID. Every call inherits IAM, PrivateLink, KMS encryption and CloudTrail logging, and provider models never train on customer data.
Example models: Claude Opus, GPT-6 Astra
Full Amazon Bedrock profileWafer
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.
Example models: Qwen 3.5 397B Turbo, GLM 5.1 Turbo
