Together AI alternatives, benchmarked
What the benchmark found. Baseten was the lowest-P99 measured alternative at 3.23 seconds, compared with 12.45 seconds for Together AI. Baseten's task success rate was 95.8%.
What this page compares. Together AI is compared with every other provider that served the same GLM 5.3 Flash microtask workload. This is not a feature-directory list: each alternative received the same 600 questions under the same streaming, reasoning, sampling, timeout, and concurrency contract.
How to read the result. The table expresses every alternative as a delta from Together AI on E2E P99, task success, and slow-tail token generation speed. Positive and negative deltas retain their natural direction, so each column states whether lower or higher is better.
Workload and configuration. Every provider received the same 600 deliberately easy structured tasks: 200 meeting-note lookups, 200 ticket-triage classifications, and 200 contract-term extractions. GLM 5.3 Flash ran with streaming enabled, reasoning low, temperature 0, top-p 1, a 256-token output ceiling, one attempt, a 20-second timeout, and per-provider concurrency one.
APIs used. The runner called each provider's OpenAI-compatible chat-completions surface. Baseten, Modal, Telnyx, Novita AI, Z.AI, Fireworks AI, Parasail, Together AI, Nebius, and DeepInfra used the model identifiers below; the links open the provider documentation used to verify each adapter.

How measured Together AI alternatives differ from Together AI
The Together AI row is the baseline and is not repeated in the alternatives table. Compare the deltas before treating a faster provider as a substitute: an alternative can gain latency while losing successful-result yield.

Workflows to test before replacing Together AI
- OpenAI-compatible application traffic. Replay your shortest blocking JSON tasks and compare E2E P95/P99 with Together AI; this benchmark's ticket-triage family is the closest measured proxy.
- Contract and document extraction. Check exact task success before migrating. The benchmark requires complete typed contract objects, so it exposes substitutions that are fast but less dependable.
- Streamed assistant responses. Compare TTFA for the visible start and generation P95 for slow-tail continuation rather than choosing from median throughput alone.
Together AI alternatives — questions unique to this comparison
