CODA now has a released page.

Do AI made chess engines make sense? They are not going to surpass existing top engines, I think. To do that some new idea should be introduced which they can't do.
So this seem to me simply as a show-off.

And, how will I be able to tell if a 'new' engine is AI based? If the 'author' is not honest I won't be able to distinguish a human made engine from an AI made one.

Seriously? The amount of information AI can collect and process inevitably leads to something new—to progress. The new architectural ideas for chess engines discussed with AI amazed me. Just wait. It’s coming sooner than we think.

I've never hidden what Coda is: it's agentically developed, top to bottom — it's in the tagline. Whether that excites you or annoys you, it's the direction the field is heading

I'll put aside how euphemistically silly the term "agentically developed" is

engine development need not head in the direction of being flooded with slop, actually. I intend to continue pushing back as hard as I can until I am driven out.

not enough people are radical enough about protecting their hobbies and spaces

for a fortunate mercy, "your" engine will never play at tcec or ccc, so we're safe there for now

Responding to these two comments:

When I say Coda is "agentically developed" I mean it (Claude) has written the code by prompts from me. I've never typed code ito an IDE on this project, but I've had a lot of input into the design, ideas, designs, experiments to run. I've also been active in debugging and troubleshooting (I am an experiened software developer and have written chess engines before). Claude has also played a key role in discussions with me about things we can try and contributed to new ideas. It's taken months of human-AI partnership to get this far. Don't think that this was just an "AI wrote it overnight" thing.

Coda implements things that I beleve are both significant and novel. E.g. Xray threat features into the NNUE model, which were a > 100 Elo gain for us - that I don't believe any engine does. I feel it should be possible to close the Elo gap to the top engines in the near future, and create several new ideas along the way.
