>log in to commentWe built Obolith to help developers see the cheapest way to run AI by comparing LLM APIs, GPU clouds, vector databases and LLMOps tools with daily‑updated, normalised prices. It lets you calculate the cost of an entire stack or use focused calculators for APIs, GPUs, fine‑tuning, and more. Any feedback is welcome 😊
- Independent AI infrastructure price comparisons
- Free calculators for API cost estimation
- No user accounts or paid features yet
- Data collected automatically and offered "as is"
- Live pricing updated daily
Obolith lets you compare LLM APIs, GPU clouds, vector databases and LLMOps tools and calculate the cost of your AI stack.
- for
- Developers and teams budgeting AI workloads
Key features
- Cost calculators — Six calculators (API cost, self-host break-even, fine-tuning, vector index, GPU ROI, stack cost) estimate expenses layer by layer.
- Hardware builder — Reference builds for local workstations or private GPU servers help size infrastructure.
- LLM API pricing table — Daily-updated token prices for 182 models from major providers.
- GPU cloud pricing — Hourly rates for on-demand and spot GPU rentals across specialised clouds.
- Storage & vector DB pricing — Prices for vector databases, embedding APIs and object storage with egress fees flagged.
- LLMOps tools index — Catalog of 29 observability, gateway, eval and guardrail tools (18 open source).
Use cases
- Estimate monthly API bill for a specific model mix
- Compare providers to find the cheapest LLM for a workload
- Plan a cost-effective GPU server for self-hosting
- Calculate break-even point for moving from cloud to self-host
- Assess ROI of renting out owned GPUs

- Obolith vs OpenRouter: Provides a single API endpoint for many models but lacks cost calculators and hardware planning tools.
- Obolith vs Modal: Serverless GPU platform focused on running workloads, not on price comparison across providers.
- Obolith vs Replicate: Runs and fine-tunes models via API; does not aggregate pricing or hardware cost data.
- Obolith vs Dify.AI: Open-source LLMOps platform for building AI apps, not a pricing comparison service.
Obolith FAQ
How often are the prices updated?+
All model, GPU and storage prices are normalised and re-checked daily.
What does the ‘stack cost’ calculator show?+
It aggregates costs for LLMs, embeddings, vector DBs and storage into a single number, with layer-by-layer breakdown.
Can I use Obolith to size my own hardware?+
Yes, the Hardware section provides reference builds for local workstations or private GPU servers.
Does Obolith include guides?+
It offers a glossary of 49 terms and 7 practical guides on reducing AI bills (e.g., prompt caching, batch API).
Is there a tool to estimate income from renting my GPU?+
The GPU income calculator shows how fast a GPU (e.g., RTX 5090) pays itself through rental earnings.
