Models by capability

“Can this model call a function?” and “can it read a screenshot?” decide the architecture before price does — a model that cannot do the thing is not a cheap option, it is not an option. Each page below lists every Bedrock model with that capability, priced, plus the part teams usually get wrong about it.

Tool use / function calling →

33 models

These are the Amazon Bedrock models that can call functions — the prerequisite for anything agentic. A model without tool use can answer from what is in the prompt, but it cannot look something up, take an action, or drive a loop.

Vision / image input →

41 models

These Amazon Bedrock models accept images as input: screenshots, scanned documents, charts, photographs and UI captures. Everything else on Bedrock is text-in, and needs an OCR step before it can read a scanned PDF.

Prompt caching →

21 models

These Amazon Bedrock models support prompt caching: a prefix you send repeatedly is stored server-side and re-read at a fraction of the input price. For anything that resends a long system prompt — agents, RAG with a fixed instruction block, chat with history — this is the single largest lever on the bill.

Batch inference →

56 models

These Amazon Bedrock models support batch inference, which processes a submitted job asynchronously at roughly half the on-demand token rate. If the work can wait hours rather than seconds, this is the simplest halving of a token bill available on the platform.

Long context (200K+) →

26 models

These Amazon Bedrock models accept at least 200,000 tokens in a single call — roughly a 500-page book, a large codebase, or a full day of meeting transcripts. Above that threshold you can usually stop chunking and let the model see the whole thing.

Embedding models →

10 models

These Amazon Bedrock models turn text into vectors for semantic search, clustering and deduplication. They do not generate text — an embedding model is the retrieval half of a RAG system, and always needs a text model beside it to answer with.

Fine-tuning / customization →

1 model

These Amazon Bedrock models can be customised on your own data — fine-tuning or continued pre-training — producing a private model only your account can invoke.

Two capabilities that interact

Prompt caching and batch inference are the two large discounts on Bedrock, and they do not combine. Batch halves the rate on work that can wait; caching cuts the cost of a prefix you resend. Picking the wrong one for the shape of your workload leaves most of the saving on the table — the cost calculator models both against your own numbers.
