How Much Does Amazon Bedrock Cost?
Amazon Bedrock's Nova models are priced for AWS-integrated workloads: Nova Pro at $0.80/1M in / $3.20/1M out and Nova Lite at $0.06/1M in / $0.24/1M out in 2026. Here is the per-token breakdown and the Bedrock-specific cost traps for agents.
Amazon Bedrock (Nova) API pricing (2026)
| Model | Input | Output | Context | Est. daily cost (10K requests) |
|---|---|---|---|---|
| Nova Pro | $0.80 / 1M in | $3.20 / 1M out | 300K | $24 |
| Nova Lite | $0.06 / 1M in | $0.24 / 1M out | 300K | $1.80 |
Pricing from provider pricing pages, July 2026. Daily cost is an estimate for 10,000 requests averaging 500 input + 200 output tokens. Source: sipi.bot AI Model Cost Comparison Database (CC BY 4.0).
What a runaway agent actually costs
The dataset estimates Nova Lite at roughly $1.80/day for 10,000 requests (500 input + 200 output tokens each, per the sourced database below). That is the happy path. Agents do not run the happy path — they retry. A function-calling agent stuck in a Nova Lite retry loop multiplies that linearly:
| Scenario | Estimated cost |
|---|---|
| Normal: 10K requests/day | $1.80/day |
| 5× retry loop (bug, bad tool output) | $9.00/day |
| 50× runaway loop (unattended overnight) | $90.00/day |
Is the Amazon Bedrock (Nova) API worth it for agents?
For autonomous agents, the per-token price is almost irrelevant next to the cumulative burn when a loop multiplies it. The right question is not which model is cheapest, but what bounds the total when the agent misbehaves. sipi.bot sits in front of the transaction and enforces per-transaction caps, daily totals, and velocity limits before the request is even allowed to scale — regardless of provider.
Hidden costs to watch for
- Retry loops: an agent that retries on transient errors multiplies token cost linearly — the single biggest agent cost driver.
- Long-context bloat: stuffing a 200K context window when 8K would do can 25× your per-call cost silently.
- Output-heavy tool calls: output tokens are typically 4–8× the input price; an agent that generates long JSON burns the expensive side of the curve.
- Provider pass-throughs: some providers add caching premiums, fine-tune hosting, or data-retention surcharges on top of per-token.
Frequently asked questions
Is the Amazon Bedrock (Nova) API expensive?
Relative to alternatives, it depends on volume and model tier. For autonomous agents the real cost driver is not the per-token price but cumulative burn when an agent loops — a cheap per-token model becomes expensive fast at retry volumes. The sourced database this page is built from estimates daily cost at 10K requests for each model.
What's the cheapest way to run this for agents?
Pick the smallest model tier that completes the task, cap context length, and — most importantly — put a pre-spend firewall in front so a retry loop cannot multiply cost unbounded. Without that, no per-token discount is safe.
Does sipi.bot replace this API?
No. sipi.bot is not an LLM provider. It sits in front of your agent and evaluates every transaction (including LLM and tool spend) against your rules in under 5ms, returning approve, block, or flag. You keep using your chosen model; sipi.bot bounds what an agent is allowed to spend on it.
