Claude Mythos 5 vs North Mini Code
Restricted-access flagship — vetted partners only. vs Cohere's free coder that beats models 4× its size, runs on your own Mac.
What I tested — same prompt, two models
I run the same fixed prompt set through every new model the day it drops — same string, one shot, single HTML file out — and I score the result 0–10 on whether it ran, how close it hit the brief, and how good it looked. Below is what came out when I gave the exact same prompts to Claude Mythos 5 and North Mini Code, side by side, on 0 shared tasks inside the Agent Operating System.
Both models were given identical prompts inside the Agent Operating System — no help, no iteration, no "best of N" tricks. I run each prompt once, save the HTML file the model produces, and score it 0–10 on whether it ran, how close it hit the brief, and how good it looked. The scoring is mine. The verdicts below are pulled from my source comparison guides at agentos.guide where I publish every score and the reasoning behind it.
Claude Mythos 5 · Not currently dispatched from Agent OS — no public API. Tracked for news coverage only.
North Mini Code · Wired into the Agent OS as the local-first coder for offline workflows. Bench scoring pending.

Strengths & weaknesses I logged
Claude Mythos 5
Strengths
- Highest-class Anthropic model — sits above Fable 5 in the Mythos line
- Same Mythos-class capability profile as Fable 5 (with restrictions)
Trade-offs
- No public API access — can't be benched against the open field
- Restricted distribution makes it effectively unavailable to most builders
North Mini Code
Strengths
- Tiny + fast — runs locally with no GPU farm required
- Out-scores models 4× its parameter count on agent-coding benchmarks (Cohere's own number)
- Zero cost — free for individuals, runs offline
Trade-offs
- Cohere's own number, not independently verified
- No goldiebench per-task scores yet

The verdict — which should you pick?
Not enough scored shared tasks yet for a head-to-head average. The live demos for both are on the matrix above — play them and form your own opinion.
If you only run one of these inside your stack, the head-to-head average above is the call. If you can run both, my honest play is to wire Claude Mythos 5 and North Mini Code both into the Agent Operating System and dispatch each from the kanban by task type — vetted enterprise partners with mythos-class access → Claude Mythos 5, local coding loops on a mac where you don't want a token meter → North Mini Code. That's the same setup I run for the 3,600+ founders inside the AI Profit Boardroom.
