Libraries

How to use NextTokenAI/NextSearch-1-M with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="NextTokenAI/NextSearch-1-M")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("NextTokenAI/NextSearch-1-M")
model = AutoModelForMultimodalLM.from_pretrained("NextTokenAI/NextSearch-1-M", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

NextSearch-1-M

NextSearch-1-M is the largest of the three NextSearch-1 web research agents: post-trained models that decompose a question, search and fetch from the live web, reconcile conflicting evidence, and return a concise answer or a structured research artifact. They are built to work as the research component inside a larger system — called repeatedly by an orchestrator — where per-call accuracy, tail latency, and cost compound.

Model	Base	Params
NextSearch-1-M (this repo)	Inkling-Small	276B-A12B MoE	weights
NextSearch-1-S	Qwen3.6-35B-A3B	35B-A3B MoE	weights
NextSearch-1-XS	Qwen3.5-9B	9B dense	weights

Technical report: nexttoken.co/research/nextsearch-1. Harness, evaluation suite, and audited benchmark golds: github.com/NextTokenAI/nextsearch.

Results

Live-web evaluation (August 2026), 12B-active M against frontier API anchors. Benchmarks: SEAL-0 (fresh/conflicting evidence, n=97), FRAMES (multi-constraint retrieval, n=100), DeepSearchQA (comprehensive answer sets, n=100), WideSearch-sub (structured table sub-tasks, n=49), and WideSearch (full tasks under the orchestrated harness, n=20). Best per column in bold.

All rows run under our harness (same tools, prompts, turn budgets, pinned task date) against audited golds with one shared judge — consistent within this table, not comparable to other papers' leaderboards. Protocol, costs, and reproduction: docs/evals.md; full analysis in the technical report.

Quick start

The weights are ~530 GB bf16 — plan for a multi-GPU node (e.g. 8×H200). See the vLLM recipe for Inkling for current serving flags; our serving notes (sampling, context caps, tool-call parsing pitfalls) are in docs/serving.md.

vllm serve NextTokenAI/NextSearch-1-M --tensor-parallel-size 8 \
  --enable-auto-tool-choice --max-model-len 65536

Recommended sampling: temperature 0.7, max 16k tokens per turn, reasoning effort 0.7. The model expects a task date in its system prompt and two tools (search, fetch); the exact prompts and tool schemas it was tuned for ship in the harness:

pip install nextsearch && nextsearch-eval run --benches seal0 --models nextsearch-1-m --n 10
