01 — Verdict

Too close to call

It is close. Our weighted score puts them within 2 points (CoBuddy 46/100, Perceptron Mk1 45/100), so choose by what matters most for your work: Perceptron Mk1 on price and CoBuddy for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

04 — Questions

Which should you choose?

Which is better: Perceptron Mk1 or CoBuddy?

It is close. Our weighted score puts them within 2 points (CoBuddy 46/100, Perceptron Mk1 45/100), so choose by what matters most for your work: Perceptron Mk1 on price and CoBuddy for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Perceptron Mk1 or CoBuddy?

Perceptron Mk1 is cheaper at $0.15 input / $1.50 output per million tokens (median across 3 API providers). CoBuddy costs $0.28 input / $1.13 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.487 per million tokens for Perceptron Mk1 versus $0.492 for CoBuddy (1× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. Perceptron Mk1 has not been scored yet and CoBuddy has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Perceptron Mk1 and CoBuddy yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Perceptron Mk1 does not support tool calling, which most coding agents need.

Which has the bigger context window?

CoBuddy has the largest context window at 131,072 tokens, against 32,768 for Perceptron Mk1. Maximum output per response: Perceptron Mk1 up to 8,192, CoBuddy up to 65,536 tokens.

Which can read images, PDFs, audio or video?

Perceptron Mk1 accepts text, images and video; CoBuddy accepts text. Perceptron Mk1 handles the widest range of inputs.

Are any of these open source?

No. Perceptron Mk1 and CoBuddy are proprietary and only available through APIs and apps.

Which is newer?

Perceptron Mk1 is the newest, released May 12, 2026. CoBuddy came out May 6, 2026.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
