See if your GPU can fine-tune a model locally. VRAM for QLoRA, LoRA and full fine-tuning, calibrated against published benchmarks.
What GPU Do I Need?
Pick a model and a context length; get the cheapest GPU or Mac that runs it. Covers RTX 5090, RTX 4090, M4 Max, A100 and H100.
Compare LLMs
Put any two models side by side: benchmarks, price per million tokens, context window and task grades.

Best LLM for…
The id8 Philosophy
Privacy First
Every tool here runs 100% in your browser. We never send your JSON, code, or prompts to our servers.
Lightning Fast
No bloat, no ads, no paywalls. Just clean, optimized code designed to do one thing perfectly.
Why we build these?
At id8, we believe the best tools are the ones you don't notice. We built this suite because we were tired of "free" online tools that were full of ads or slow to load.
Whether you are repairing broken AI output with JSONSurgeon, checking hardware with CanIRunLLM, or sanitizing code with PasteDetox, our goal is to save you those few seconds that add up to hours.
Built for the AI Era
id8 Tools is a free suite of developer utilities designed for the workflows that matter most when working with AI: fixing broken output, running large language models locally, managing secrets securely, and cleaning the noise from everyday text tasks.
JSON Surgeon repairs malformed JSON from ChatGPT, Claude, Gemini, or any API in seconds. CanIRunLLM calculates exactly how much VRAM and RAM you need to run Llama 4, DeepSeek R1, Qwen 3, or Gemma 4 locally on your hardware. PromptZipper compresses your prompts to reduce token count and cut costs on any LLM API.
Env Secrets Manager encrypts .env files in the browser using AES-GCM and lets you share them via secure magic links or steganography PNGs — zero server involvement. PasteDetox strips invisible Unicode characters and smart quotes that silently break code. Tweet Splitter splits long posts into Twitter/X threads and LinkedIn carousels instantly. No accounts, no paywalls, no data collection.
