## How they compare

Meta's Model API is new and still in public preview. Muse Spark 1.3 has a 1M context at $1.25 in and $4.25 out, with cached input at $0.15, and the endpoint speaks OpenAI, Anthropic and a stateful agentic format. It also serves Muse Image at $0.01 per image and transcription at $0.18 per hour. Bedrock, launched in 2023, offers 100+ models from 18+ providers, including Meta models, and it inherits IAM, PrivateLink, KMS and CloudTrail on every call. One is a new entrant, the other an established marketplace.

Data handling is the sharpest contrast. Meta's Contributor tier cuts prices to $0.10 in and $0.20 out, but only if Meta trains on your prompts and completions, which rules it out for most business traffic. Bedrock states that provider models never train on customer data. For prototyping, cheap image generation and experiments where data sharing is fine, Meta's API is attractive. For production enterprise agents, Bedrock's longer track record, governance and AgentCore tooling carry more weight.

## 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.

### Meta

Meta has moved from open Llama releases toward its own closed API. Meta Superintelligence Labs builds the Muse family, and in July 2026 Meta opened a public preview of the Meta Model API with Muse Spark 1.1, a multimodal reasoning model aimed at agentic coding, tool use and computer use. The current lineup runs through Muse Spark 1.3 with a 1M token context. Standard pricing is $1.25 in and $4.25 out per million tokens, with cached input at $0.15, and the endpoint speaks OpenAI Chat Completions, Anthropic Messages and a stateful agentic format.
