Together AI. Full-stack AI platform, powered by cutting-edge research

Where OpenRouter is ahead

It also holds understand: authentication documented. Together AI misses it.

And on operate, agent compatibility verified. Together AI misses it.

Where Together AI is ahead

Together AI passes public docs discoverable, and OpenRouter does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: fast time to first request, copyable quickstart, official typescript sdk and official python sdk. OpenRouter misses those.

And on operate, canonical workflow succeeds and observable execution. OpenRouter misses those.

What neither does

Both fail search discoverable, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. OpenRouter leads 100 to 60. OpenRouter misses search discoverable, public docs discoverable, mcp discoverable; Together AI misses search discoverable, clear product positioning, mcp discoverable.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. OpenRouter leads 92 to 38. OpenRouter misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Together AI misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. OpenRouter leads 88 to 52. OpenRouter misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available, mcp integration available; Together AI misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available.

Operate. OpenRouter leads 44 to 35. OpenRouter misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution; Together AI misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing
