Amazon Bedrock vs Together AI: key differences

Bedrock is a hyperscaler control plane. One API reaches 100+ models from 18+ providers, including Claude, GPT-6 Astra, Nova and open models like DeepSeek, and every call inherits IAM, PrivateLink, KMS and CloudTrail. Together AI is an open-model specialist. It serves thirty-plus text models such as Kimi K3, DeepSeek V4, GLM 5.2 and Qwen 3.8, plus image, video and speech, and adds dedicated deployments, raw GPU clusters and managed training. It says new open models land within days of release.

The split comes down to closed models and customization depth. Only Bedrock gives Claude and GPT under an existing AWS security posture, and AgentCore adds a governed agent runtime. Together goes further on open weights: LoRA and full SFT from $0.48 per million training tokens, RL in closed beta with checkpoints that deploy straight to inference, and H100 clusters from $3.19 an hour reserved. Bedrock fine-tunes and imports custom checkpoints too, but third-party analyses put most of its models 20 to 35% above direct prices. Together has no free tier.

What Amazon Bedrock and Together AI 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

Together AI

Together AI is the broadest open-model platform in the category. One bill covers per-token serverless inference, batch at up to 50% off, provisioned throughput with a 99% SLA, dedicated deployments, raw GPU clusters, managed fine-tuning and code sandboxes for agents. The text catalog runs past thirty open models, including DeepSeek V4, Kimi K3, GLM 5.2, Qwen 3.8 and MiniMax M3, plus image, video, speech and embedding models. Token prices sit at parity with Fireworks and Baseten.
