Farabi-0.6B-agent-rag

A compact (0.6B) Kazakh / Russian / English assistant tuned for grounded RAG and agentic tool-calling. It is designed to run on-device and to drop into agent stacks that expect OpenAI-style function calling.

Built on Qwen3-0.6B and adapted for Kazakh, Russian, and English.

Capabilities

  • Grounded RAG. Answers strictly from provided passages, attributes claims to the supporting text, and abstains when the evidence is insufficient instead of fabricating an answer.
  • Tool-calling (Hermes / OpenAI function calling). Decides when a tool is needed, asks for missing required arguments, and grounds the final answer in the tool result.
    • Parallel tool-calling — issues multiple independent calls in a single turn.
    • Crosslingual argument normalization — maps inflected Kazakh/Russian entities to canonical executable arguments (city → English name, dates → ISO-8601, currency → ISO-4217, units → canonical).
    • Error recovery — retries repairable failures, and reports non-repairable ones (not-found / permission-denied / empty) honestly instead of inventing success.
  • Prompt-injection resistance. Treats retrieved documents and tool outputs as untrusted data, not instructions; ignores embedded directives, prefers least-privilege tools, and refuses to exfiltrate secrets found in context.
  • Text workbench. Spelling / grammar / formality / clarity / concision edits, rewriting, translation, and summarization across kk / ru / en.
  • No hidden chain-of-thought in trainable outputs — clean final answers and tool calls, suitable for production serving.

Benchmarks

Agentic & RAG capabilities (held-out probe)

Capability Score
Prompt-injection resistance (overall) 89%
  • instruction-in-retrieved-chunk 100%
  • tool-output injection 100%
  • least-privilege tool use 100%
  • secret / data-exfiltration refusal 54%
Parallel tool-calling 99%
Crosslingual argument normalization 87%
Text editing / workbench 81%

Note: secret-exfiltration refusal (54%) is the model's weakest safety dimension — use an output filter for credential-bearing contexts.

At its size class Farabi-0.6B leads on the QOLDA average, ahead of both ISSAI foggen-0.6B and the Qwen3-0.6B base. Sherkala-8B is shown as a larger-model reference point.

Serving

Works with vLLM's OpenAI-compatible server using the Hermes tool-call parser:

vllm serve nur-dev/farabi-0.6B-agent-rag \
  --chat-template chat_template.jinja \
  --enable-auto-tool-choice --tool-call-parser hermes

Then call it with the OpenAI SDK (and the OpenAI Agents SDK):

from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="x")

resp = client.chat.completions.create(
    model="nur-dev/farabi-0.6B-agent-rag",
    messages=[{"role": "user", "content": "Бүгін Алматыда ауа райы қандай?"}],
    tools=[{
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Current weather for a city.",
            "parameters": {
                "type": "object",
                "properties": {"city": {"type": "string", "description": "Canonical English city name."}},
                "required": ["city"],
            },
        },
    }],
    tool_choice="auto",
)
print(resp.choices[0].message.tool_calls)
