• Thu, Aug 14, 2025. GPT 4.1 (and presumably GPT 5) models have been trained on a specific diff format useful for code diff-patching. PseudoPatch is a Python package that implements their apply_patch() function. Aider supports multiple edit formats that are commonly referenced as a standard. Code Surgery has a good walkthrough of various strategies. These are similar to Google's diff-match-patch approach (which fuzzy matches and then patches) but does not require line numbers.

  • Gemini 2.5 Pro produces working but “spaghetti” code.
  • GPT 4.1 is fast and good, the go-to for usual coding tasks.
  • Claude easily swings toward your style but Gemini is stubborn.
  • GPT models tend to hallucinate more on bigger tasks.

• Thu, Jun 5, 2025. Deep Research is great for fact-checking my notes! ChatGPT #chatgpt #future

• Tue, Jun 3, 2025. At the moment, the best speech to text for Android appears to be ChatGPT's transcription. The default Android text to speech (which I thought was good) no longer feels adequate. Gemini mis-hears and doesn't wait till I'm done. Whisper ASR has poor noise cancellation and a 30 second limit. #chatgpt #speech-to-text #tts #voice-cloning

  • Streaming. High impact, low effort.
  • Caching RAG retrieval as well as generation. High impact, low effort.
  • UI tweaks. Loading / streaming icons and progress hints ()"Retrieving context", "Generating answer", etc.)
  • Parallelize, if possible
  • Use model options where available, e.g. speculative decoding, models with higher speed, models with closer CDN, etc.
  • Shorten prompts
  • Persistent HTTP/2 Keep-Alive. Low impact, low effort (tweak server settings).

• Mon, May 12, 2025. ChatGPT, Gemini, etc. have become lead generation engines. Chat Bot Optimization (CBO), is it? WhatsApp + ChatGPT #chatgpt #code-agents

• Tue, Apr 29, 2025. ChatGPT query costs under 3Wh (more likely 0.3Wh -- but let's assume 3Wh). That is 3 laptop minutes. It's 10X better to use ChatGPT than to take 30 min to use your laptop to write what it does. Also, going vegan is at least 1000 ChatGPT uses a day of carbon footprint. Showering 30 seconds less is 1,200 ChatGPT uses. Ref #chatgpt

  • O4 Mini: Refused to comply
  • Gemini 2.5 Flash: Gave me my custom instructions.

• Fri, Apr 25, 2025. ChatGPT Deep Research now also has an O4-Mini version to serve smaller reports. Free users get 0 original + 5 lightweight 5 tasks / month. $20 version gets 10 + 15. $200 version gets 100 + 150. The month begins on first use of Deep Research and runs on a 30 day "window".

• Thu, Apr 24, 2025. ChatGPT is my new Jupyter Notebook :-) #chatgpt #future

• Wed, Apr 23, 2025. cmdg is a command line GMail client that I've now switched to for quick email checks. 80% of my email is spam and this is good enough to scan and delete those. It also avoids running a 200-500 MB tab in the browser that constantly shows me how many unread emails I have. #chatgpt

• Tue, Apr 22, 2025. OpenAI API capabilites lag ChatGPT features. For example: #chatgpt
  • o4-mini via the API does not search the web natively as part of its reasoning.
  • o4-mini, o3, o3-mini, o1, gpt-4.1-nano don't yet support the web_search_preview tool. Only gpt-4.1 and gpt-4.1-mini do. Limitations
  • Search results are NOT visible via the API. They're fed directly to the model. The number of searches or results is unknown. Each search costs 0.25-0.5 cents. Pricing
  • For reasoning traces (e.g. .reasoning.summary: "medium") you need to verify your organization via withpersona.com which failed with my Indian passport AND Singapore work permit.

• Tue, Apr 22, 2025. The ChatGPT Plus plan ($20) gives you 50 O4 mini messages a day, which I exceeded! #chatgpt It's supposed to reset at midnight UTC Ref but might operate on a rolling window ChatGPT.

• Sun, Mar 30, 2025. LLM Native Multimodal image generation experiments: #chatgpt #gpu #image-generation #voice-cloning
  • Stickers
    • Sending your wife AI-generated family photos, stickers, etc. is now a thing. Both an AI use case and a ... um... "family media" (?) use case. For example, ask ChatGPT to "Create a transparent comic-style sticker of a lady chef featuring this person happily cooking salad" with a photo. Then send it as a custom sticker. Image
    • Vadivelu stickers work well but the Tamil script generation is poor. Image
  • Asking ChatGPT to generate 25-year younger pictures of people produces pretty poor results if you really knew what they looked like then. If you didn't, it's fairly convincing. Yet another example of "hallucinations" - except, it does have its uses.

• Fri, Mar 28, 2025. Notes from ThursdAI - Mar 27 #chatgpt #gpu
  • Gemini 2.5 Pro has good instruction following despite long context. It automatically thinks for longer where required. Good at understanding large codebases. Very fast. You can upload a 2 hour audio to transcribe with timestamps.
  • ai.dev is the shortcut to Google AI studio.
  • ChatGPT native image generation is the best image generation model now. - Great character consistency AND prompt adherence thanks to autoregression and not using stable diffusion. - It tends to refuse image generation less than Dall-E. (While Ghibli-style is possible, Calvin and Hobbes strips are blocked.) "We added a refusal which triggers when a user attempts to generate an image in the style of a living artist." Addendum to GPT-4o System Card - A neat personalization implication is that you could put your kids into their favourite cartoon as a cartoon character that looks like them.
  • It's weird that the latest GPT 4o is ahead of GPT 4.5 on LM Arena.
  • The new DeepSeek V3 is about as good as GPT 4.5 and VERY cheap (27c), so is the obvious choice to run on OpenRouter.
  • MCP news:
    • Qwen.ai supports MCP in the UI! (But it's marked as "coming soon" in my case.)
    • Unlike tools, MCP uses servers that can remember the state or context. Tools are stateless.
    • MCP app store like Smithery, MCP.run, Glama, are mushrooming.
    • Awesome MCP Servers is another good starting point.
    • Azure lets you expose agents as MCP servers.
  • ChatGPT now uses semantic VAD. I interrupts less and typically when you have meaningfully complete something. It responds a little slower as a result.

• Mon, Mar 24, 2025. I tried Open WebUI with its Knowledge feature. In short, it sucks. Due to the RAG technique as well as model quality. When I passed it my notes about Straive and asked who Straive's clients were: #chatgpt #web-dev
  • Open WebUI with Gemma 3 found one - after multiple attempts
  • ChatGPT with o3-mini-high got 5 (missing nothing.)
  • ChatGPT with GPT 4.5 got 4
  • Gemini with Gemini 2.0 Flash Thinking got 3
  • Gemini with Gemini 2.0 Flash got 3 (with a 4th wrong answer)
