Difficulty estimating daily cost of AI model usage

1. The Problem — What is Difficult or Frustrating?
Manually tracking and analyzing AI conversations to determine the cost per day of different AI models can be time-consuming and prone to errors.
2. Who Experiences It — The Affected Audience

Data scientists or AI product managers

3. The Proposed Tool — Specific Web App or Software Concept
A web application that connects to AI model providers, pulls usage data, and displays daily cost estimates for each model.
4. Core Features & Architecture
1.
API usage collector

Periodically calls the providers' usage endpoints, authenticates with stored keys, and stores token and request counts.

SolvesEliminates manual export of logs and counting of tokens
2.
Pricing engine

Maps each model's pricing schedule to the collected usage and computes a daily cost breakdown.

SolvesRemoves the need to manually apply pricing formulas
3.
Dashboard view

Shows a per‑model, per‑day cost chart with filters for date range and project tags.

SolvesProvides an at‑glance answer to which model costs more on any given day
5. Potential Value — Operational Impact

Data scientists and AI product managers instantly see accurate cost figures without spreadsheet gymnastics, allowing them to choose models based on cost.

Limitations & Technical Boundaries
The tool cannot see private on‑premise deployment usage logs nor account for custom enterprise discount agreements.
6. Suggested Validation Questions (Not Researched Facts)

Suggested exploration questions to confirm real demand, alternatives, and willingness to pay before building:

  • How often do you need to manually compile token usage and calculate daily spend for each model?
  • Possible existing alternatives to check: OpenAI usage dashboard, Anthropic usage reports, Azure cost analysis tools. Gap to test: whether these tools cover automatic cross‑model daily cost comparison.
  • What monthly price would you consider fair for a service that eliminates the manual cost‑tracking workflow?
Technical Feasibility & Platform Terms Risk

Depends on access to the providers' usage reporting endpoints and authentication tokens.

🛠️ Technical Blueprint & Implementation Concept
Build a React SPA (create‑react‑app) for the UI, using Recharts for time‑series charts and Ant Design for tables/filters. The frontend authenticates via OAuth2/OIDC (Auth0 or Keycloak) and stores provider API keys encrypted in the browser’s IndexedDB, then sends them to a FastAPI (Python 3.11) backend over HTTPS. FastAPI runs a Celery worker pool (Redis broker) that schedules periodic tasks (cron via Celery beat) to call each provider’s usage endpoint: OpenAI’s `/v1/dashboard/billing/usage`, Anthropic’s `/v1/usage`, Azure OpenAI’s billing API, etc. Use `httpx` with async support and retry logic (tenacity). Responses are normalized into a PostgreSQL 15 schema (tables: provider, model, date, prompt_tokens, completion_tokens, request_count). A pricing engine module loads a YAML file mapping model identifiers to per‑1k‑token rates (including prompt/completion split) and applies any tiered discounts. The engine runs as a SQLAlchemy ORM transaction that writes daily cost rows to a `costs` table. The dashboard endpoint (`/api/costs`) accepts query params (date_range, model, tag) and returns aggregated JSON; the React client consumes it and renders stacked bar charts. Secure the API with JWTs signed by the auth provider. Deploy via Docker Compose: frontend, backend, celery worker, Redis, PostgreSQL; host on a modest VPS or Kubernetes cluster.
📊 The Limitations of Current Alternatives
Existing dashboards (OpenAI, Anthropic, Azure) only show aggregate spend per account and lack granular per‑model, per‑day breakdowns across multiple providers. Teams currently export raw logs, manually parse token counts with scripts, then copy‑paste into spreadsheets to apply pricing tables—introducing transcription errors and delaying insight. Enterprise cost‑analysis tools (e.g., CloudHealth) are costly, require full cloud account integration, and do not natively understand AI token pricing tiers, forcing custom adapters that are rarely maintained. Consequently, practitioners spend significant time reconciling disparate reports instead of focusing on model performance.
🎯 Key Engineering Value & Benefits
The tool automates cross‑provider usage ingestion and applies precise pricing rules, delivering near‑real‑time cost visibility. This eliminates manual log processing, reduces human error in spend calculations, and enables data scientists to make informed model selection decisions instantly. By storing normalized usage data, downstream cost‑optimization scripts can run without re‑querying APIs, lowering API call volume and associated compute overhead. Overall, the solution streamlines financial governance of AI workloads and prevents budget overruns.
