Compare LLM Models

compare-llm-models

Read-only

Browse and filter the whole LLM catalogue and get back a ranked table: price, quality (ELO), efficiency and capabilities. Use this when the user wants to SEE THE FIELD — 'show me models under $1/1M', 'which providers have vision models', 'list open-weight models above ELO 1300'. For a single PICK under a budget use recommend-llm-model; to weigh 2-4 NAMED models against each other use compare-models-side-by-side. Prices come from optimtoken.optimnow.io where reachable; the response's provenance says which tier served them and whether they are vendor-verified. Filter by provider, price tier (category), openness, capability, price range, or minimum ELO score. Optionally enrich with business metrics for a use case. Price tier and openness are independent: a model can be Frontier-priced and open-weight at once. Reports both list-price cost and the optimized cost achievable with prompt caching and the batch API. Prices, costs and scores are final as returned: rounded and ranked server-side, and dated by provenance. The text block is a numbered table of the same figures.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Max models to return (default: 15)
`minElo`	No	Minimum Chatbot Arena ELO score. Typical range 1000-1500; ~1400 is roughly frontier-class. Models with no ELO score never satisfy this.
`category`	No	Price tier, matched by exact equality (case-insensitive): Frontier, Mid-tier, Budget, Image. This is cost only — self-hostability is the separate `openness` axis.
`openness`	No	Filter by self-hostability, derived from the licence: Open source, Open weights, Proprietary, Unknown
`provider`	No	Filter by provider name (e.g. 'OpenAI', 'Anthropic', 'Google')
`capability`	No	Capability, matched by exact equality (case-insensitive): Text, Vision, Reasoning, Agents, Image Gen, Audio. Any other string returns zero matches. There is no Code capability: for what coding costs, use useCasePreset codingTask.
`volumePreset`	No	Monthly request volume: 10k, 100k, or 1m. Default: 100k
`maxInputPrice`	No	Max input price per 1M tokens in USD
`useCasePreset`	No	Workload shape, which sets tokens per request: supportTicket (1.5k in / 500 out), knowledgeQA (2k / 800), meetingSummary (10k / 1.2k, batch-eligible), marketingContent (2.5k / 1.8k), codingTask (3k / 2k), invoiceProcessing (1.5k / 600, batch-eligible), callSummary (2k / 700, batch-eligible), agentWorkflow (6k / 3k). Default: supportTicket
`maxOutputPrice`	No	Max output price per 1M tokens in USD
