Anthropic Cost Optimization
Cut your Claude API bill. OhChimp reads org usage, flags Opus traffic for cheaper models, batchable jobs at 50% off, and unused prompt caching.
What OhChimp optimizes for Anthropic
Some of the cost levers OhChimp checks for Anthropic. Each one becomes a reviewable plan you approve before anything changes.
Frontier-priced traffic on Opus
OhChimp prices every model from your usage report and flags frontier-priced models (output above $30 per million tokens, like Opus) carrying material monthly spend. Routing the share of that traffic that quality allows to a cheaper model such as Sonnet or Haiku is usually the single largest direct-API lever, and the plan names the models to look at.
Standard-tier work the Batch API would halve
The Message Batches API bills input and output tokens at a 50% discount for jobs that can complete asynchronously. OhChimp finds models with standard-tier spend above $10 a month (evals, backfills, classification, scheduled jobs are typical) and writes a plan to route the latency-tolerant share through Batches. The saving is computed per model as an upper bound, since only you know which requests tolerate the async window.
Prompts that never hit the cache
Cache reads bill at roughly 10% of the input rate, but only when prompts are structured for prefix caching. OhChimp finds cache-capable models running over a million input tokens with zero cached reads and zero cache-creation writes (the sign that no cache_control breakpoints are set), then recommends ordering stable content (system prompt, tool definitions, examples) first so prefixes match and repeat.
Per-model spend you can actually see
OhChimp aggregates token usage per model and service tier, prices uncached input, cache reads, cache writes, and output at the model's real rates, and projects a monthly cost sorted highest first. That turns one opaque invoice line into a ranked list of where the money goes, so you fix the biggest model first.
Priority-tier tokens billing above standard
Anthropic's Priority Tier bills above the standard on-demand rate. OhChimp tallies priority-tier tokens per model and flags them so you can confirm whether that latency guarantee is worth the premium for traffic that could run on standard. The token estimate prices these at the standard rate, so it reads as a lower bound for any model with priority traffic.
Token estimate cross-checked on the real bill
OhChimp reconciles its per-token estimate against billed spend from the Cost Report API, broken down by description. That surfaces non-token line items the token math excludes (web search, code execution) so you see the full picture and trust the numbers the plan is built on.
Worked example
Say OhChimp reads 30 days of usage and finds most of your spend sits on Opus for a nightly classification job, plus a Sonnet workload pushing millions of input tokens with zero cache reads and no cache writes.
It writes one plan to route the latency-tolerant classification traffic through the Batches API at the 50% rate, and another to add cache_control breakpoints so the repeated Sonnet prefix starts hitting the cache. You press apply. OhChimp cannot yet measure what a single Anthropic plan saves, so it does not mark one VERIFIED. The projected saving stays an estimate, and when the 30 days of monitoring end the result reads "Inconclusive."
Anthropic cost optimization FAQ
How does OhChimp connect to Anthropic?
With a read-only organization Admin API key (sk-ant-admin...) in the x-api-key header. OhChimp verifies the key has admin scope by listing one org member, then reads only the Messages Usage Report and the Cost Report. It never calls the Messages API and never stores prompts, completions, secrets, or application data.
Does OhChimp need write access or see my prompts?
No. The Admin API key OhChimp uses reads organization usage and cost data only. It sees token counts per model and service tier plus billed amounts, never the contents of your requests or responses. Nothing about your workloads is stored.
What Anthropic costs can OhChimp actually reduce?
Frontier-priced spend on Opus that could move to Sonnet or Haiku, standard-tier traffic the Batch API would bill at a 50% discount, and cache-capable models running heavy input volume with zero cached reads. It also flags priority-tier tokens billing above standard and cross-checks every estimate against your real Cost Report spend.
How is the Anthropic web search tool priced, and does OhChimp see that spend?
Anthropic bills the web search tool at $10 per 1,000 searches, plus standard token rates for the search results Claude reads as input. Those search fees never appear in token counts, so a per-token estimate misses them. OhChimp reads your billed spend from the Cost Report, grouped by description, alongside its token estimate, so non-token charges such as web search and code execution stay in the picture instead of hiding in the gap between the estimate and your bill.
Who applies the changes, and can they be rolled back?
You do. Each fix is a reviewable plan with a confidence score, a risk level, and rollback steps. Nothing changes until you click apply, and you are always the one who clicks. OhChimp applies the matching code and infrastructure changes together.
How are the savings verified, and how is OhChimp priced?
Today Anthropic savings stay estimates. OhChimp cannot yet measure what a single Anthropic plan saves, so it does not mark one VERIFIED, and when the 30 days of monitoring end the result reads "Inconclusive." The only savings OhChimp measures today come from lowering the CPU and memory requests of a Kubernetes Deployment, StatefulSet, or DaemonSet. Pricing is a flat monthly fee with no cut of your savings, plus a year-one ROI guarantee that lets you request a refund of your first 12 months of subscription fees if the verified savings on your Costs tab fall short of them. Estimated savings do not count.
Why the unused-cache lever has a wrong side to land on: Claude prompt caching cost: 90% off, or 25% more.
