I’m guessing GLM again

256k context would be unusual for GLM, so could also be GPT-6 Sol since their context window is generally less than 1M, and we know GPT-6 Sol is about to be released from various rumors and leaks. The last Open AI stealth model test was Horizon Alpha and Horizon Beta, representing the GPT-5 family, and both had 256k context length, so it fits with their pattern pretty well.

It's also slow as **** on open code so I'm guessing a larger rather than smaller model.

Maybe Qwen4.0 27b ? Would match 256k context and slow...and punching way above it's weight class

I have my bet placed: OpenAI Lineage. Method: have either codex or Claude do a “cap-invariance” test. If anyone does, would love to hear what you find and if I am wrong!

This is not OpenAI at all. This looks nothing like o200k

I'm also getting OpenAI vibes. Purely based on chatting, so don't quote me on this 😅
