If someone asked me, “What’s changed this year in LLMs”, here’s my list:"

• Prompt engineering is out. Evals are in. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7335146366681194496/
• Hallucinations are fewer and solvable by double-checking. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7326902628490059776/
• LLMs are great for throwaway code / tools. https://www.linkedin.com/feed/update/urn%3Ali%3AugcPost%3A7319277426029539329/
• LLMs can analyze data. No more Excel. https://www.linkedin.com/feed/update/urn%3Ali%3Aactivity%3A7345062233996988417/
• LLMs are good psychologists. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7326504476712808449/
• Image generation is much better. https://www.linkedin.com/feed/update/urn%3Ali%3AugcPost%3A7304716144379076608/
• LLMs can speak well enough to co-host a panel. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7283025621503356930/
• … and create podcasts. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7326544867734540288/

But:

• LLMs are still not great at slides. https://www.linkedin.com/feed/update/urn%3Ali%3Ashare%3A7311066572113002497/
• LLMs still can’t follow a data visualization style guide.
• LLMs can’t yet create good sketch notes. Apr 2026: With Nano Banana, they can, and Nano Banana Pro doesn’t even make spelling mistakes.
• LLMs still draw bounding boxes as well as specialized models.
• ~Agents (LLMs running tools in a loop) can think only for 6 min. Apr 2026: With Opus 4.6 and GPT 5.4, agents run for several hours independently.

UPDATES:

• 16 Apr 2026: LLMs don’t speak niche foreign language dialects perfectly. Gemini speaks Dutch, Tamil, etc. well but not specific accents. ElevenLabs cannot clone MGR’s voice perfectly yet.
