tamebi 0.2.2

Detect hardware and estimate LLM model inference capability

tamebi

Detect your hardware. Know what you can run.

tamebi is a CLI tool that automatically detects your machine's hardware (CPU, RAM, GPU, disk) and tells you exactly which LLM models you can run — with estimated memory usage, throughput, and time to first token.

Install

pip install tamebi

or with uv:

uv pip install tamebi

NVIDIA, AMD, and Apple Silicon are all detected automatically — no extra flags or extras needed.

Quick Start

tamebi check

CLI Reference

tamebi check

Detect hardware and estimate which LLM models can run.

Flag	Short	Default	Description
--json	-j	false	Output as JSON instead of rich tables
--context-length	-c	4096	Context length in tokens. KV cache scales linearly with this — 4K vs 128K changes memory dramatically
--batch-size	-b	1	Concurrent requests. Each gets its own KV cache. Set >1 if planning to serve multiple users
--verbose		false	Show detailed detection info (driver versions, etc.)

tamebi update

Pull the latest model catalog from the remote. The catalog updates automatically in the background but you can force a refresh with this command.

tamebi update

Examples

# Basic hardware check
tamebi check

# JSON output for scripting
tamebi check --json

# Estimate for serving 4 concurrent users with 8K context
tamebi check --batch-size 4 --context-length 8192

# Use each model's native max context window instead of the 4K default
tamebi check --context-length 0

# Force-refresh the model catalog
tamebi update

Supported Hardware

Vendor	Detection Method	Details
NVIDIA	nvidia-ml-py (NVML)	Model, VRAM, CUDA version, compute capability
AMD	rocm-smi (subprocess)	Model, VRAM (requires ROCm)
Apple Silicon	system_profiler	Chip model (M1/M2/M3/M4), unified memory
CPU-only	psutil + py-cpuinfo	Cores, threads, frequency, architecture

Model Catalog

The catalog is automatically updated weekly and covers the latest releases from major labs including Meta, Mistral, Google, Qwen, DeepSeek, GLM, MiniMax, Kimi, Liquid, and AllenAI. Models are fetched directly from HuggingFace Hub — no manual maintenance required.

Run tamebi update at any time to pull the latest catalog.

How Estimation Works

Memory is estimated per model and precision:

Total VRAM = Model Weights + KV Cache + Overhead

Model Weights = params (billions) × bytes_per_param
  FP16: 2 bytes | INT8: 1 byte | INT4: 0.5 bytes

KV Cache = 2 × layers × num_kv_heads × head_dim × context_len × bytes × batch_size
  (GQA-aware: uses KV heads, not Q heads)

Overhead = 15% of weights (activations + fragmentation) + 0.5 GB (NVIDIA only)

Performance estimates (tokens/sec, time to first token) are based on hardware-class lookup tables. They show ranges, not exact numbers — actual performance depends on drivers, software stack, and workload.
