Direct Model Invocation

In addition to utilizing auto to route between models, you can directly invoke Arcee Small Language Models and 3rd party LLMs (Claude, GPT, etc) using the Conductor API. This makes it easy to use a large variety of models with only changing a parameter in the API request.

If you're on the free plan and don't have a valid payment method on file, you will only be able to directly invoke Arcee SLMs. To upgrade your plan reach out to [email protected].

The models which can be directly invoked are:

Model	API Name	Description
Virtuoso Small	virtuoso-small	A 14B parameter SLM from Arcee AI, distilled from Deepseek V-3. Virtuoso Small is extremely performant and excels at simple tasks such as text generation and summarization.
Blitz	blitz	A 24B parameter SLM from Arcee AI, distilled from Deepseek V-3 Blitz offers blazing fast response times and exceptionally low costs with strong general knowledge. Ideal for simple and creative tasks.
Virtuoso Medium	virtuoso-medium	A 32B parameter SLM from Arcee AI, which was distilled from Deepseek V-3 giving it an impressive knowledge distribution.
Virtuoso Large	virtuoso-large	Arcee AI's premier 72B parameter SLM which competes with the leading LLMs on complex and analytical tasks.
Coder Large	coder	A 32B parameter SLM from Arcee AI fine-tuned to excel at Coding tasks.
Caller Large	caller-large	A 32B parameter SLM from Arcee AI fine-tuned to excel at function calling.
GPT-4.1	gpt-4.1	A closed-source LLM from Open AI with impressive analytical and complex problem solving capabilities.
Claude Sonnet 3.7	claude-3-7-sonnet-20250219	A closed-source LLM from Anthropic with strong performance on coding and complex tasks.

API Usage Example:

CURL

curl -X POST https://conductor.arcee.ai/v1/chat/completions \
  -H "Authorization: Bearer $ARCEE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
        "stream": true,
        "model": "blitz",
        "messages": [
          {
            "role": "user",
            "content": "Your prompt here"
          }
        ]
      }'

Python

To switch the model you're invoking, simply change the "model" value from "blitz" to any of the model API names in the table above.
