Hi everyone!

If Codex already has a strange affinity for goblins, why not /hatch a /pet by yourself?

Or browse for some random inspiration here.

OpenAI is considering buying Pinterest. Do you see this acquisition as promising?

Today, I read in the news that OpenAI is considering "expanding its data footprint" and possibly buying Pinterest, as there is a lot of data on it just for the sake of users finding inspiration (which can be key for purchase decision making and understanding personas Pinterest has 600M+ users).

I also take into account how Pinterest started to resent the proliferation of AI content there users do not like it so much (as far as I know, OpenAI also wants to have its own social network, and Sora curation is a bit reminiscent of that)

Does OpenAI have the potential to replace LinkedIn? Their latest project.

I often hear that LinkedIn is starting to be cringe, becoming a second Facebook, but let s be honest: it s still a career platform. A little cringe, but it still is.

On the other hand, Sam Altman introduced a new ambition OpenAI Jobs Platform an AI-powered hiring platform, expected to launch by mid-2026.

How do you approach Context Engineering when building with OpenAI models?

Lately, I have been experimenting with how to feed context into GPT models more effectively.

For example, when fine-tuning or working with larger context windows, I have noticed that the dilemma is in organizing the surrounding information, rather than the prompt itself. Last week, I came to know that it's called Context Engineering.

View all

GPT-5.1 represents a meaningful step forward in LLM capabilities. Three key improvements stand out:

1. Engine Segmentation & Personality Presets

The ability to segment different engine types with distinct personalities is genuinely useful. As a GTM builder, this means I can deploy contextually-optimized responses without extensive prompt engineering overhead.

2. Superior Instruction Following

The model now handles multi-step constraints simultaneously. Complex instructions that previously required 3-4 iterations now work on the first try. This directly reduces latency in production systems.

3. Improved Tone Adaptation

GPT-5.1 understands conversational context better. It shifts tone appropriately based on input, which matters more than people realize for enterprise adoption. Technical superiority loses to human-like interaction every time.

The Real Unlock: This isn't a revolutionary leap. It's a solid incremental advance that compounds when deployed at scale. The real advantage goes to teams building on top of this—not those claiming AGI is here.
