InternVL2 8B needs ~8.4 GB but GTX 1650 4GB only has 4.0 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 8.4 GB, but this setup only exposes 4.0 GB of usable VRAM.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.

No, InternVL2 8B requires more memory than GTX 1650 4GB provides.
InternVL2 8B (8B parameters) requires approximately 8.4 GB of memory with Q4_K_M quantization.
The recommended quantization for InternVL2 8B is Q4_K_M, which balances quality and memory efficiency.
On GTX 1650 4GB, InternVL2 8B achieves approximately 2.1 tokens per second decode speed with a time-to-first-token of 91547ms using Q4_K_M quantization.
For coding workloads, InternVL2 8B on GTX 1650 4GB receives a F grade with 2.1 tok/s and 4K context.
On GTX 1650 4GB, InternVL2 8B can safely use up to 4K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
