OpenAI Introduces GPT-5.4 Mini: Faster, Better Coding Support
By
–
introducing gpt-5.4 mini: OpenAI (@OpenAI) GPT-5.4 mini is available today in ChatGPT, Codex, and the API. Optimized for coding, computer use, multimodal understanding, and subagents. And it’s 2x faster than GPT-5 mini. openai.com/index/introducing… — https://nitter.net/OpenAI/status/2033953592424731072#m

3D Model Processing Pipeline for Image-to-Image Transformation
By
–
Can you imagine a piece of code that takes the 3D model data, transforms/processes it, and then passes it on to the next Image-To-Image step? Let's call this the full program, because the word pipeline seems to be difficult.

3D Model Processing and Geometric Transformations in AI Pipelines
By
–
Hypothetically, if the full pipeline can be shown to do rotations/transformations, then by your explanation of geometric transformations above, then it *must* be processing 3D model data?

Mixed Results: Diffusion in Text, AR in Images, Hybrid Architectures
By
–
honestly its gotten more mixed. diffusion in text, AR in images. hybrid archs everywhere (altho most researchers tell me the differences between SSM vs transformers not that material). not clear.

BullshitBench update: The new GPT-5.4 mini and nano models score quite low. This screenshot shows OpenAI models only, on the full list would put GPT-5.4-mini around 40th place and Nano is around 70th place. Again thinking didn't help much at all. https://t.co/EdwOBStKa4 pic.twitter.com/mxBGoFUzio

Couldn't resist getting OpenAI Codex to render me a pelican for every combination of model and reasoning effort – I do think gpt-5.4 xhigh came out the best, the pelican has a fish in its beak!
