Compare models

compare_models

Compare two or more AI models by ID or name to view their IQ, rankings, and benchmarks side-by-side. Unknown model IDs are reported but do not stop the process.

Instructions

Side-by-side detail for several models by id/name. Unknown ids are reported, not fatal.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It discloses that unknown IDs are reported without fatality, but lacks details on output format, read-only status, or limits on number of models.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with essential information, front-loaded with the action. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter comparison tool with no output schema, the description adequately covers purpose, error handling, and scope.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is high (100%), baseline is 3. The description adds value by noting how unknown IDs are handled, which relates directly to the parameter behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Side-by-side detail' (compare) and resource 'models by id/name', and distinguishes from sibling tools like get_model (single model) and list_models (list without comparison). It also notes error handling behavior.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use (comparing multiple models) and provides helpful context about unknown IDs being non-fatal, but does not explicitly state when not to use or name alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
