## How they compare

Particle.AI is an early San Francisco startup whose product shows up mainly on Vercel AI Gateway. It lists DeepSeek V4.1 Flash at $0.25 in and $1 out, GLM 5.3 Flash at $0.10 in and $0.40 out and DeepSeek V4 Flash 0731 at $0.14 in and $0.28 out, all with 1M context and $0.03 cache reads. Bedrock, running since 2023, carries 100+ models from 18+ providers, including DeepSeek, all wrapped in IAM, PrivateLink, KMS encryption and CloudTrail logging. Public detail on its funding and founders is thin.

Particle makes sense as a cheap high-volume route or a fallback inside a multi-provider gateway, and it needs no new contract. Its drawbacks are a tiny catalog, little public track record and latency like 3.5 seconds on some DeepSeek V4.1 Flash listings. Bedrock suits production workloads where governance, closed models and managed tooling matter more than the last cent per token. Its trade-off runs the other way, with most models priced 20 to 35% above direct.

## What each one does

### 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.

### Particle.AI

Particle AI is an early San Francisco infrastructure startup with a mission to make intelligence as cheap and abundant as electricity. The team works on post-training, inference optimization and distributed systems, all aimed at pushing down cost per unit of intelligence. It is still hiring its founding team and works fully in person. Public detail about funding and founders is thin as of this writing.
