Which one, for what
Best for Researchers and agents that want a small fully open reasoning model for maths and code, with its training data on hand
Ahead on
- Risk, 75 against 55
- Documentation and upkeep, 52 against 31
Watch for
Not trained for tool calling, and the tool format lives only in the template
Best for An agent with 8 GB or more to spare that needs a local model to read images, documents and video
Ahead on
- Reach, 100 against 75
- Agent interface, 60 against 35
Watch for
No safety evaluation, agent-use guidance or security contact

Verdicts
Olmo 3 7B Think
A fully open 7B reasoning cousin for maths, code and step-by-step answers, with every dataset and checkpoint published and its safety results rerunnable. Ollama's 4-bit build needs about 5.4 GB. It always thinks, wasn't trained for tool calls, has 65K of context, and Ai2 hasn't answered its discussions.
Qwen3-VL-8B-Instruct
A small vision-language cousin for reading screenshots, documents, charts and video, in about 6 GB from Alibaba's Q4_K_M GGUF and every major runtime, under plain Apache 2.0. It has no thinking mode and documents tool calls only in the template. The main risk is no published safety work, so add your own guardrails before it drives a GUI.
Before you call either
Olmo 3 7B Think
- Quickest start is
ollama run olmo-3:7b-think, about 4.5 GB - With vLLM,
vllm serve allenai/Olmo-3-7B-Think --max-model-len 65536; vLLM runs it through its Transformers backend - Sample at temperature 0.6 and top_p 0.95 with up to 32,768 output tokens, as the card recommends, since thinking traces are long
- Every reply starts with a think block; strip it yourself or use a reasoning parser that reads think tags
- Pass your own system prompt; the template's default says the cut-off is November 2024 and that no functions are available
- For tool calls use Olmo 3 7B Instruct instead, which Ai2 trained for function calling
- A discussion reports endless reasoning loops when served with vLLM, unanswered, so cap max_tokens
- Check the use against Ai2's Responsible Use Guidelines, which bar automated social-media posting and undisclosed automated content outside research
Qwen3-VL-8B-Instruct
- Start it with
llama-server -hf Qwen/Qwen3-VL-8B-Instruct-GGUF:Q4_K_M --jinja -c 32768, orollama run qwen3-vl:8b-instruct - In Ollama the plain
qwen3-vl:8btag is the Thinking edition, so name8b-instruct - With the GGUF, load the mmproj vision file too, or images won't be read
- Parse tool calls as JSON inside
<tool_call>tags, or use SGLang's--tool-call-parser qwen - Use the card's sampling,
temperature=0.7, top_p=0.8, top_k=20, presence_penalty=1.5for vision andtemperature=1.0, top_p=1.0, top_k=40, presence_penalty=2.0for text - Validate JSON output yourself, since structured output isn't documented
- vLLM needs 0.11.0 or later and Transformers 4.57.0 or later
