Tev1 (experimental) — local AI model by Together AI
Written by Jakub Rusinowski · Last updated
Together AI's experimental Jev-inspired decision models, supervised fine-tunes of Qwen3.5 that pick one option from a structured decision. Available in Ollama.
Variants
The smallest Tev1 (experimental) variant needs about 1 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache.
| Model | VRAM at Q4 | VRAM | Context | Run it |
|---|---|---|---|---|
| Tev1 4B → 4B | ~3.6 GB | Not published | ollama pull tev1 | |
| Tev1 0.8B → 0.8B | ~1.3 GB | Not published | ollama pull tev1:0.8b |
Memory is quantized weights plus overhead at Q4_K_M, from the same engine as the GPU & VRAM checker.
How to run Tev1 (experimental) locally
Install Ollama, then pull the tag.
ollama pull tev1Pick a size above for its own VRAM figure, speed estimate and install command.
Recommended GPU
The cheapest catalogued GPU that runs Tev1 (experimental) locally (min 1 GB VRAM) is the Intel Arc B570 (10 GB).
Tev1 (experimental) — frequently asked questions
How much VRAM does Tev1 (experimental) need?
Tev1 (experimental) needs about 1 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Tev1 4B (4 GB, Q4_K_M); Tev1 0.8B (1 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Can I run Tev1 (experimental) on an RTX 4090 (24 GB)?
Yes — Tev1 (experimental) runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.
What quantization should I use for Tev1 (experimental)?
Q4_K_M is the best balance of quality and VRAM for Tev1 (experimental) in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
How do I run Tev1 (experimental) locally?
Tev1 (experimental) is a decision model: it is called over an HTTP endpoint (/v1/systemone), not chatted with. Where a variant is available in Ollama 0.35 or newer, pull it with `ollama pull` and send requests to the local server; the others ship their own server. Each variant page shows the exact commands for that model.
