A 5,000-document corpus on the site calculator is $163.28/month on S3 Vectors and $510.52/month on OpenSearch Serverless Classic. $160 of the smaller bill is Claude Sonnet 5.5.
There is no universal price. A July 2026 first-party benchmark put one AgentCore support silhouette near $791 a month at 50,000 sessions — platform plus a small model, before integration or a reviewer.
On September 21, 2026 the Strands Agents team reported 28% lower token cost across six benchmarks, and 77% less than Claude Code with Fable 5 on Terminal-Bench. That figure is not an AgentCore bill.
AWS Settings spend limits, still a limited release on 23 Sep 2026, alert at 50%, 75%, and 90%, then pause the project. Do nothing for 90 days and AWS deletes the project data. The minimum limit is the greater of $20 or AWS's estimate.
On September 22, 2026 AWS made GPT-6 Sol and GPT-6 Luna generally available on Bedrock. OpenAI’s internal eval found Sol makes about half as many factual mistakes as GPT-5.6 Sol. On September 29 GPT-6.1 Sol followed. Ultrafast mode followed on October 8. Here is the lane routing.
On Sep 18, 2026 AgentCore microVM Runtime V2 went GA — AWS P75 cold starts 1.9–2.0s vs 5.4–30s on V1, but consumption rates rose to $0.1276/vCPU-hour and $0.0169/GB-hour. Memory reclaim waits 120 seconds.
Score volume, pain, data, and write-risk. Readiness below 16 out of 30 means do not fund writes. McKinsey found 62% experimenting and 23% scaling in at least one function.
On Aug 6, 2026 ElastiCache added Graviton4 M8g/R8g/C8gn for Valkey and Memcached — up to 47% higher throughput, 43% lower P99, 31% better price-performance vs Graviton3. Field guide: family pick, RI traps, canary checklist.
On July 16, 2026 AWS removed the 30-day Standard residency gate for Standard-IA and One Zone-IA lifecycle transitions — day-0 IA can cut first-month storage ~46% on 10 TB cold logs, but the 30-day IA billing minimum and $0.01/GB retrieval fees still apply.
On July 31, 2026 AWS shipped CloudWatch managed Prometheus collectors. For the AWS Example 22 shape (100 hosts x 50 metrics @ 60s), OTLP ingestion is $54/mo vs $1,500 classic custom metrics if you do not double-ingest.
On June 15, 2026 Grok 4.3 GA on Bedrock Mantle at $1.25/$2.50 per 1M. On August 19, 2026 Grok 4.6 added Converse + US Geo/Global CRIS at $2.00–$2.20 / $6.00–$6.60. On September 28, 2026 Grok 4.7 shipped at the same rates — do not jump on name alone.
On July 30, 2026 AWS cut Bedrock on-demand prices 80% for GPT-5.6 Luna and 20% for Terra — Luna is now $0.22/$1.32 per 1M tokens. Here is the routing math and what not to re-price overnight.
