  <em>IQuest-Q1 performance across benchmarks. DeepSeek-V4-Flash/Pro refer to the official 0731/0813 releases, respectively. Humanity's Last Exam is reported without tools. IQuest-CLIBench is our in-house benchmark for CLI user experience.</em>
</p>

### Benchmark Notes

For reproducibility, we recommend using a temperature of 1.0, top-p of 0.95, and top-k of 20, with Claude Code `2.1.140` or Codex `0.142` as the respective harness.

For each model, we report the publicly reported score; otherwise, we evaluate the model using the corresponding benchmark setup:
(1) Harness: For agentic coding tasks, we use mini-SWE-agent for DeepSWE v1.1, and Claude Code for other tasks. For Agents' Last Exam, we evaluate our model using Claude Code `2.1.258`. Because our models currently do not have multimodal capability, we replace multimodal content inputs in the agent conversation with placeholders during tokenization. (2) Runtime: We set six-hour limits for CyberGym, eight hours for Terminal-Bench 2.1.




## Quick Start

Start a server as described in [Deployment](#deployment), install the client with `pip install openai`, and then call the OpenAI-compatible API:

```python
from openai import OpenAI

client = OpenAI(base_url="http://127.0.0.1:8000/v1", api_key="sk-iquest")
response = client.chat.completions.create(
    model="IQuest-Q1",
    messages=[
        {"role": "user", "content": "Hello! Can you briefly introduce yourself?"},
    ],
    temperature=1.0,
    top_p=0.95,
)
print(response.choices[0].message.content)
```

## Deployment

For production deployment, we recommend using [SGLang](https://github.com/sgl-project/sglang/pull/41590) or [vLLM](https://github.com/IQuestLab/vllm-iquest-q1).

    "draft_sample_method": "probabilistic",
    "rejection_sample_method": "standard",
    "enforce_eager": false
  }'
```

### Tool Use and Agent Integration

Use a gateway that supports tool calling via **Anthropic Messages** for `Claude Code` and **OpenAI Responses** for `Codex`.

#### Claude Code

We recommend version `2.1.140` and the IQuest-Q1[1m] client-side setting does not change 512K context limit.

```bash
export ANTHROPIC_MODEL="IQuest-Q1[1m]"
export ANTHROPIC_DEFAULT_SONNET_MODEL="IQuest-Q1[1m]"
export ANTHROPIC_DEFAULT_OPUS_MODEL="IQuest-Q1[1m]"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="IQuest-Q1[1m]"
export CLAUDE_CODE_SUBAGENT_MODEL="IQuest-Q1[1m]"
export CLAUDE_CODE_MAX_OUTPUT_TOKENS="131072"
export CLAUDE_AUTOCOMPACT_PCT_OVERRIDE="80"
export CLAUDE_CODE_AUTO_COMPACT_WINDOW="524288"
export API_TIMEOUT_MS="3000000"
export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC="1"
export CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS="1"
export ANTHROPIC_BASE_URL="http://example-iquest-q1-link"
export ANTHROPIC_AUTH_TOKEN="sk-iquest-q1"
claude --model IQuest-Q1
```

#### Codex CLI

We recommend version `0.142.0`.

```
export OPENAI_API_KEY="sk-iquest-q1"
export MODEL_ID="IQuest-Q1"
# Add /v1 if required by your gateway's Responses endpoint.
export BASE_URL="http://example-iquest-q1-link"

## Limitations

- **Text-only input.** This checkpoint has no native image, audio, or video input capability.
- **Output reliability.** Generated explanations and code can be incorrect. Review code changes and verify them with task-appropriate tests.
- **Tool integration.** Tool calls use the IQuest-specific format in the chat template. Structured tool execution and reasoning extraction require compatible serving parsers and an agent harness.
- **Challenges in Real-World CLI Tasks.** Real-world CLI tasks often require iterative debugging and verification. IQuest-Q1 may overlook constraints, repeat failed attempts, or leave issues unresolved, necessitating human oversight.
- **Ongoing development.** IQuest-Q1 remains at an early stage, with substantial limitations in its capabilities and reliability. Much work remains, and we still have a long way to go.
