## How they compare

Mistral is one of 18+ providers on Bedrock, so the choice is often how to buy the same model. Bedrock wraps every call in IAM, PrivateLink, KMS encryption and CloudTrail logging, and adds Knowledge Bases, Guardrails, fine-tuning and Custom Model Import. Third-party analyses put most Bedrock models about 20 to 35% above direct API prices, with Claude an exception. Going direct, Mistral lists Medium 3.5 at $1.50 in and $7.50 out, Large 3 at $0.50 in and $1.50 out and Small 4 at $0.15 in, with Batch at half price and cached input up to 90% off. Bedrock also discounts, with batch at 50% off and provisioned throughput at 20 to 40% off on a one or six month commitment.

Bedrock's advantage is breadth and governance. One API reaches Claude, GPT-6 Astra, Nova and DeepSeek next to Mistral, and AgentCore adds a serverless agent runtime with memory, an MCP gateway and Cedar-based policies. Model availability varies by region, though, and add-ons like Knowledge Bases can run up idle charges. Direct access puts Mistral's own products on one key, including Codestral, OCR, Voxtral and the Agents API, plus EU and US regional endpoints and a Priority Tier with uptime SLAs. The weights are open, so Medium 3.5 can leave the cloud entirely and run on four GPUs. Context stays at 256K either way.

## 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.

### Mistral AI

Mistral AI is a Paris lab that sells its models through La Plateforme, its own API, and releases most of them as open weights. It consolidated the lineup in 2026. Mistral Medium 3.5, released April 28, is a dense 128B model that merges instruction following, reasoning and coding into one set of weights, and it replaced both Devstral 2 and the Magistral reasoning models. It costs $1.50 in and $7.50 out per million tokens and scores 77.6% on SWE-Bench Verified by Mistral's count. Mistral Small 4, a 119B mixture-of-experts model with 6.5B active, costs $0.15 in and $0.60 out. Mistral Large 3, a 675B MoE under Apache 2.0, runs $0.50 in and $1.50 out. All three carry a 256K context window.
