colab-finetuning

colab-finetuning is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 67 tokens per session (1,542 once invoked), scanned A, original, Apache-2.0.

A tool for fine-tuning language models on Google Colab GPUs, including free or paid remote machines. Fine-tuning means continuing model training on examples so it behaves better for a specific task.

In plain words
What is it for?
Run supervised, preference-based, reinforcement-learning, vision, and text-to-speech model-training workflows remotely through Unsloth.
Why use it?
It helps when you need a GPU but do not have one locally. Colab is useful for experiments, though sessions can disconnect and are not suited to long-running production jobs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

colab-finetuning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Google Colab Fine-Tuning

Fine-tune LLMs using Google Colab GPUs directly from the openscience CLI. Connect to free or paid Colab runtimes and run Unsloth training workflows remotely.

When to Use Colab Fine-Tuning

Use Colab when:

  • You don't have a local GPU but need to fine-tune a model
  • You want free GPU access (T4 with 15GB VRAM on Colab Free)
  • Training models up to ~14B parameters (4-bit QLoRA)
  • Quick experiments and prototyping before scaling to cloud
  • Colab Pro/Pro+ for A100 (40-80GB) access

Don't use Colab when:

  • You need persistent long-running jobs (>12h) — use Tinker or cloud providers
  • Training 70B+ models — use Lambda, RunPod, or multi-GPU cloud
  • You need guaranteed uptime — Colab may disconnect idle sessions
  • Production training pipelines — use managed services

Colab vs Alternatives:

Need Use
Free GPU, quick experiments Google Colab
Managed cloud training (any size) Tinker
Persistent multi-GPU training Lambda / RunPod
Local GPU available Unsloth directly
Enterprise with SLA Colab Enterprise (Vertex AI)

Quick Start

Step 1: Generate Bridge Notebook

Use colab_notebook tool with workflow="bridge"

This creates a openscience-bridge.ipynb file that establishes a WebSocket tunnel between openscience and the Colab GPU.

Step 2: Open in Colab

  1. Go to colab.research.google.com
  2. Upload the bridge notebook (File → Upload notebook)
  3. Select GPU runtime (Runtime → Change runtime type → T4 GPU)
  4. Run all cells
  5. Copy the WebSocket URL that appears

Step 3: Connect from openscience

Use colab_connect tool with connection_url="wss://..."

Step 4: Run Training

Use colab_finetune tool with:
  workflow: "sft"
  model: "unsloth/Qwen3-4B-unsloth-bnb-4bit"
  dataset: "mlabonne/FineTome-100k"

Or execute individual cells:

Use colab_execute tool with code="import torch; print(torch.cuda.get_device_name(0))"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

colab-finetuning is a skill published in the GitHub repository synthetic-sciences/openscience (3,432 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 1,542 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
