# TensorFeed AI Model Comparison

> TensorFeed AI Model Comparison is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Compares 2–5 AI models side-by-side, returning normalized benchmarks, pricing, live provider status, recent news, and per-benchmark rankings in a single payload.

## Facts

- Endpoint: POST https://tensorfeed.ai/api/premium/compare/models
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tensorfeed-ai-65e38787 -d '<json body>'
```

Example prompt: Can you compare GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro side by side — I want to see their pricing, benchmark scores, current provider status, and which one ranks best overall?

## When to prefer this

Choose this endpoint when you need a ready-to-rank, normalized comparison of multiple AI models at once — especially when you want pricing, benchmarks, and live status in a single call rather than making separate requests to each provider. Ideal for agents building model-selection logic or recommendation features.

## Known failure modes

- Fewer than 2 models specified — returns validation error
- More than 5 models specified — returns validation error
- Unknown or misspelled model identifier — returns null entries or error for that model
- Provider status API temporarily unavailable — status fields may be stale or null
- Payment of $0.02 USDC not fulfilled — 402 Payment Required response

## Output

A normalized JSON payload with pricing per token, benchmark scores across all available metrics (with explicit nulls for missing keys), live provider status, recent news mentions, and per-benchmark rankings for each of the 2–5 requested models.
