Migrate from Together AI

Cheaper than Together on most open-weight models (we run them on CF edge), with the same OpenAI-compatible API, plus access to frontier closed models.

CLI automation for Together AI isn't shipped yet — you'll do this manually below. PRs welcome at packages/aig-cli/src/commands/migrate.ts.

TL;DR — three lines

# 1. set your AIgateway key
export AIGATEWAY_API_KEY="sk-aig-..."

# 2. change the base URL
base_url="https://api.aigateway.sh/v1"  # was https://api.together.xyz/v1

# 3. search-and-replace the env var name

What changes, line-by-line

The table below is what aig migrate together rewrites. If you're doing it by hand, do these in order.

Before / after — Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="https://api.together.xyz/v1",
    api_key=os.environ["TOGETHER_API_KEY"],
)
r = client.chat.completions.create(
    model="anthropic/claude-opus-4.7",
    messages=[{"role": "user", "content": "Hi"}],
)

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aigateway.sh/v1",
    api_key=os.environ["AIGATEWAY_API_KEY"],
)
r = client.chat.completions.create(
    model="anthropic/claude-opus-4.7",
    messages=[{"role": "user", "content": "Hi"}],
)

Behavioral notes

• Model slugs differ — Together uses the HuggingFace-style path, AIgateway uses provider/model. Check /models for the AIgateway equivalent of your current Together model.
• Inference quality is identical (same upstream weights); routing layer is different.
• BYOK: bring your Together key if you have negotiated discounts, route through AIgateway, pay 0% platform fee on those calls.

Credit match

Email your last invoice from Together AI to switch@aigateway.sh and we match the credit up to $1,000 (24-hour turnaround). Or read the full pitch at /switch/together.

What to read next

• BYOK — bring your existing Together AI provider keys; pay 0% on those routes.
• Sub-accounts — per-customer keys with spend caps; the closest analogue to workspace-isolated keys.
• All migration guides — same docs for OpenRouter, Portkey, Helicone, LiteLLM, Together, Replicate, Fireworks, Requesty.
