Immediate verdict: specialist finance platform or proactive city sidekick
Carrot Labs operates SuperPenguin, an AI cost management and spend intelligence platform designed for engineering teams, finance departments, and engineering leaders who need granular visibility into LLM costs across OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, and more than 100 providers. SuperPenguin attributes every API request to customers, features, teams, and prompt versions, reconciles SDK estimates against actual provider invoices, and connects Cursor and GitHub to show what each merged pull request cost in AI spend. Karpo is a free, proactive city sidekick that lives in messaging apps and helps individuals and groups discover local spots, coordinate timing around weather and transit, and build backup plans when the original idea falls through. The two products serve entirely different decision boundaries: SuperPenguin answers "Where did every AI dollar go?" while Karpo answers "Where should we meet, and what if it rains?"
Use Carrot Labs for its specialist job, then text Karpo when location, taste, timing, and other people determine what happens next.
Karpo cannot replace SuperPenguin's specialist work. If your organization runs AI-powered features in production, ships code with Cursor, or needs to attribute LLM spend to individual customers or product lines, you need SuperPenguin or a comparable AI finance platform. Karpo has no SDK, no billing reconciliation, no per-request attribution, and no integration with provider admin APIs. It will not help you forecast next month's OpenAI invoice or identify which feature is burning budget.
What Carrot Labs SuperPenguin does
SuperPenguin is an AI spend intelligence platform operated by Carrot Labs AI, Inc. It provides three layers of visibility: a no-code spend dashboard that syncs billing data from connected provider admin keys, Python and TypeScript SDKs that attribute cost to every API request in real time, and a Cursor PR cost feature that ties AI spend to the pull requests engineers ship. The spend dashboard displays total spend across all connected providers, month-over-month trends, per-model breakdowns, AI spend forecasts on Pro plans, and invoice reconciliation that compares tracked spend against actual billed amounts to surface hidden charges and billing errors. The dashboard supports OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, Vercel AI Gateway, AWS Bedrock, Azure OpenAI, and more.
The SuperPenguin SDK wraps existing provider client libraries in Python and TypeScript. Calls go directly to the provider; SuperPenguin is not a proxy. The SDK adds less than 10 milliseconds of overhead on non-streaming requests and less than 5 milliseconds time-to-first-token impact on streaming. By default, the SDK collects cost metadata only: token counts, model name, provider, latency, and attribution tags such as customer ID, feature, team, environment, prompt key, and prompt version. The SDK does not collect prompts, responses, images, tool arguments, or provider API keys by default. Organizations on Pro or Enterprise plans may opt in from the dashboard to sampled, encrypted capture of text prompts and outcomes for offline recommendation analysis; opt-in capture strips images and audio, applies built-in redaction, and is encrypted at rest, and owners can delete captured content at any time from Settings.
The Cursor PR cost attribution feature connects Cursor and GitHub to show what each merged pull request cost in AI spend, broken down by engineer and project. It works automatically with no SDK or code changes. A local collector on the user's machine uploads conversation and message text, conversation timing, file names and content hashes, and commit statistics used to match IDE activity to pull requests. The collector does not upload source file contents, tool arguments, or tool outputs, and applies best-effort secret scrubbing by default before upload. The collector is open source and available for review on GitHub.
SuperPenguin supports spend alerts that notify teams in Slack, email, or Discord when daily spend thresholds, spike detectors, or monthly budget caps are breached. Alerts fire within minutes of a threshold breach. The platform also provides per-request observability, allowing teams to drill down to the cost of every request and see which customers, features, and prompt versions drive spend.
What Karpo does
Karpo is a free, proactive city sidekick that works through messaging apps. It helps individuals and groups discover local spots, coordinate timing around weather and transit, and build backup plans when the original idea falls through. Karpo is taste-aware, city-focused, and supports group coordination directly in messaging threads. It offers weather-sensitive alternatives, timing suggestions based on real-world conditions, and proactive recommendations that anticipate what might go wrong before you leave the apartment.
Karpo does not require account setup, SDK integration, or provider admin keys. It lives in the messaging apps people already use and does not charge for usage, seat count, or managed spend volume.
Four things Karpo does well for city coordination
Free and proactive in messaging
Karpo is free to use and lives in messaging apps, so there is no separate dashboard to check, no API key to rotate, and no invoice to reconcile. It proactively surfaces alternatives and backup plans before you ask, which is useful when weather changes, transit is delayed, or a venue closes unexpectedly.
Group coordination without switching contexts
Karpo works in group messaging threads, so everyone in the conversation sees the same suggestions, timing updates, and backup options. This reduces the coordination overhead that comes from forwarding screenshots, copying links, or switching between a planning tool and the group chat.
Weather-sensitive alternatives and timing
Karpo adjusts recommendations based on current and forecast weather conditions. If rain is expected, it suggests covered or indoor alternatives. If a heatwave is forecast, it highlights shaded parks or air-conditioned venues. This weather awareness is built into the recommendation flow, not bolted on as a separate feature.
Taste-aware local discovery
Karpo learns individual and group preferences over time and surfaces local spots that match those tastes. It focuses on city-specific discovery rather than generic search results, so recommendations feel relevant to the neighborhood, the season, and the group's history.
Five things Carrot Labs SuperPenguin does better
Per-request attribution across customers, features, and teams
SuperPenguin attributes every LLM API call to the customer, feature, team, environment, prompt key, and prompt version that triggered it. This granularity allows engineering and finance teams to see exactly which product features drive spend, which customers consume the most tokens, and which prompt versions are most expensive. Karpo has no concept of per-request attribution, no SDK, and no way to tag or track individual API calls.
Invoice reconciliation and spend forecasting
SuperPenguin compares tracked spend from SDK telemetry against actual provider invoices and surfaces discrepancies, hidden charges, and billing errors. The Pro plan includes AI spend forecasting that projects end-of-month costs based on current usage trends. Karpo does not sync billing data, does not reconcile invoices, and does not forecast spend.
Cursor PR cost attribution for engineering ROI
SuperPenguin connects Cursor and GitHub to show what each merged pull request cost in AI spend, broken down by engineer and project. This allows engineering leaders to see cost per engineer, cost per project, and spot spend that shipped nothing. The feature works automatically with no SDK or code changes. Karpo has no integration with code editors, version control, or engineering workflows.
Multi-provider dashboard with unified trends and alerts
SuperPenguin brings OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, Vercel AI Gateway, AWS Bedrock, Azure OpenAI, and more than 100 providers via LiteLLM into a single auto-syncing dashboard. It displays unified trends, model breakdowns, and spend alerts that fire in Slack, email, or Discord within minutes of a threshold breach. Karpo does not integrate with AI providers, does not track spend, and does not send alerts about budget thresholds.
SDK telemetry with minimal latency impact
The SuperPenguin SDK adds less than 10 milliseconds of overhead on non-streaming requests and less than 5 milliseconds time-to-first-token impact on streaming. Telemetry logging is fully async, and calls go directly to the provider without proxying. This low-latency design allows production teams to instrument every request without degrading user experience. Karpo has no SDK and no telemetry infrastructure.
Pricing and access
SuperPenguin offers a Free plan for individuals getting started, which includes all dashboard features, per-request attribution via SDK, reconciliation, and email support for up to 2,000 USD in managed AI spend per month. The Growth plan costs 30 USD per month and supports up to 5,000 USD in managed spend, three team members, and cost alerts via Slack, email, or Discord. The Pro plan costs 200 USD per month and supports up to 20,000 USD in managed spend, ten team members, AI spend forecast, and Cursor PR cost attribution. The Enterprise plan offers custom pricing for organizations managing more than 20,000 USD in monthly AI spend, unlimited team members, and SAML SSO marked as coming soon. Pricing is based on the AI spend managed through SuperPenguin, not on seat count or API call volume.
Karpo is free to use and does not charge for usage, seat count, or managed spend volume. It does not require account setup, API keys, or billing configuration.
Decision guidance: when to use which tool
Use SuperPenguin if your organization runs AI-powered features in production and needs to know where every AI dollar goes. It is the right choice for engineering teams that want per-request cost visibility, finance departments that need to reconcile SDK estimates against provider invoices, and engineering leaders who want to see what each pull request cost in Cursor spend. SuperPenguin is also the right choice if you need to attribute LLM costs to individual customers, product features, or teams, or if you need spend alerts that fire in Slack or email when thresholds are breached.
Use Karpo if you and your group need help coordinating city plans, discovering local spots, and adjusting for weather or timing changes without leaving your messaging app. Karpo is the right choice for proactive recommendations, group coordination, and backup plans when the original idea falls through. It does not replace AI spend intelligence, billing reconciliation, or engineering ROI analysis.
The two tools do not overlap. SuperPenguin tracks AI spend for teams shipping LLM-powered products. Karpo helps individuals and groups navigate the city through messaging. If your engineering team uses Cursor and ships AI features, you need SuperPenguin. If that same team wants to coordinate dinner plans after the sprint demo, they can use Karpo. Neither tool replaces the other.
Frequently asked questions
Does SuperPenguin store my prompts or responses?
By default, no. The SDK logs cost metadata only: token counts, model, latency, and attribution tags. Prompt and response text are not captured unless your organization opts in from Settings on a Pro or Enterprise plan, the SDK allows capture, and the call is sampled. Opt-in capture is text-only, strips images and audio, applies redaction by default, and is encrypted at rest. Owners can delete captured content at any time from Settings.
Will the SuperPenguin SDK slow down my API calls?
The SDK adds less than 10 milliseconds of overhead on non-streaming requests and less than 5 milliseconds time-to-first-token impact on streaming. Telemetry logging is fully async, so the impact on production latency is minimal.
Can I track OpenAI or Anthropic spend by customer?
Yes. Install the SuperPenguin Python or TypeScript SDK, wrap your provider client, and pass a customer_id in the metadata on each request. The attribution dashboard then breaks down cost by customer, feature, team, and prompt version in real time.
Can I see how much each pull request cost in AI spend?
Yes. Connect Cursor and GitHub, and SuperPenguin attributes Cursor spend to the pull requests it produced, broken down by engineer and project. It works automatically with no SDK or code changes. Cursor is supported today.
Does Karpo charge for usage or seat count?
No. Karpo is free to use and does not charge for usage, seat count, or managed spend volume. It does not require account setup, API keys, or billing configuration.
Can Karpo help me track AI spend or reconcile provider invoices?
No. Karpo is a proactive city sidekick for messaging apps. It does not integrate with AI providers, does not track spend, and does not reconcile invoices. For AI cost management, use SuperPenguin or a comparable AI finance platform.
What if I only want the SuperPenguin billing dashboard, not the SDK?
That works. Connect a supported provider admin key, and the Spend Dashboard syncs billing data automatically. The SDK is optional and only required if you want per-request attribution, customer tagging, or prompt versioning.
