Together AI Alternative for GPT & Claude Workloads
Together AI excels at open-weight inference. For closed GPT and Claude models at a flat 65%/50% off list, this API covers that side of the stack — often alongside Together, not instead of it.
What Together AI is for
Together AI runs open-weight models — Llama, Qwen, DeepSeek and peers — on its own serving stack, with dedicated endpoints and throughput options for teams that want control over open models. For that job it is a strong, focused platform.
What it does not serve is the closed frontier: GPT and Claude models are not in its catalog, because they are only available through the vendors and their resellers.
The complementary half
This API covers exactly that other half — GPT models at 65% off list and Claude at 50% off — on both OpenAI-compatible and native Anthropic protocols with one key. GPT-5.6 Sol runs $1.75 in / $10.50 out per 1M tokens; Claude Sonnet 4.6 runs $1.50 / $7.50.
A common architecture keeps Together for cheap open-model volume (classification, routing, drafting) and points the frontier calls here — one gateway for each class of model, both on per-token billing.
When to consolidate here
If open-weight models were a cost optimization you can now skip — GPT-6 Luna at $0.035 per 1M input tokens prices many bulk tasks below open-model rates once quality is accounted for — collapsing to one vendor-direct gateway removes a integration to maintain.
Compare the numbers for your own traffic: this site's model pages list every GPT and Claude rate next to official list prices, and Together's pricing page covers the open-model side.
FAQ
Does this API replace Together AI?
Not for open-weight models — it serves GPT and Claude only. Teams running both classes typically use both platforms side by side; consolidating here makes sense when your volume tasks fit GPT-5.6 Luna's price point.
Why route frontier calls through a gateway at all?
One key and one invoice for both vendors, a flat discount off list price, and protocol choice (OpenAI-compatible or native Anthropic) without maintaining two integrations.
How do the discounts work?
A fixed multiplier at billing time: 65% off list on every GPT model, 50% off on every Claude model. No volume tiers to negotiate — the rate is the same from the first token.
