New OpenAI feature: Predicted Outputs (via) Interesting new ability of the OpenAI API - the first time I've seen this from any vendor.
If you know your prompt is mostly going to return the same content - you're requesting an edit to some existing code, for example - you can now send that content as a "prediction" and have GPT-4o or GPT-4o mini use that to accelerate the returned result.
OpenAI's documentation says:
When providing a prediction, any tokens provided that are not part of the final completion are charged at completion token rates.
I initially misunderstood this as meaning you got a price reduction in addition to the latency improvement, but that's not the case: in the best possible case it will return faster and you won't be charged anything extra over the expected cost for the prompt, but the more it differs from your prediction the more extra tokens you'll be billed for.
I ran the example from the documentation both with and without the prediction and got these results. Without the prediction:
"usage": {
"prompt_tokens": 150,
"completion_tokens": 118,
"total_tokens": 268,
"completion_tokens_details": {
"accepted_prediction_tokens": 0,
"audio_tokens": null,
"reasoning_tokens": 0,
"rejected_prediction_tokens": 0
}
That took 5.2 seconds and cost 0.1555 cents.
With the prediction:
"usage": {
"prompt_tokens": 166,
"completion_tokens": 226,
"total_tokens": 392,
"completion_tokens_details": {
"accepted_prediction_tokens": 49,
"audio_tokens": null,
"reasoning_tokens": 0,
"rejected_prediction_tokens": 107
}
That took 3.3 seconds and cost 0.2675 cents.
Further details from OpenAI's Steve Coffey:
We are using the prediction to do speculative decoding during inference, which allows us to validate large batches of the input in parallel, instead of sampling token-by-token!
[...] If the prediction is 100% accurate, then you would see no cost difference. When the model diverges from your speculation, we do additional sampling to “discover” the net-new tokens, which is why we charge rejected tokens at completion time rates.
Claude 3.5 Haiku
Anthropic released Claude 3.5 Haiku today, a few days later than expected (they said it would be out by the end of October).
[... 478 words]Bringing developer choice to Copilot with Anthropic’s Claude 3.5 Sonnet, Google’s Gemini 1.5 Pro, and OpenAI’s o1-preview. The big announcement from GitHub Universe: Copilot is growing support for alternative models.
GitHub Copilot predated the release of ChatGPT by more than year, and was the first widely used LLM-powered tool. This announcement includes a brief history lesson:
The first public version of Copilot was launched using Codex, an early version of OpenAI GPT-3, specifically fine-tuned for coding tasks. Copilot Chat was launched in 2023 with GPT-3.5 and later GPT-4. Since then, we have updated the base model versions multiple times, using a range from GPT 3.5-turbo to GPT 4o and 4o-mini models for different latency and quality requirements.
It's increasingly clear that any strategy that ties you to models from exclusively one provider is short-sighted. The best available model for a task can change every few months, and for something like AI code assistance model quality matters a lot. Getting stuck with a model that's no longer best in class could be a serious competitive disadvantage.
The other big announcement from the keynote was GitHub Spark, described like this:
Sparks are fully functional micro apps that can integrate AI features and external data sources without requiring any management of cloud resources.
I got to play with this at the event. It's effectively a cross between Claude Artifacts and GitHub Gists, with some very neat UI details. The features that really differentiate it from Artifacts is that Spark apps gain access to a server-side key/value store which they can use to persist JSON - and they can also access an API against which they can execute their own prompts.
The prompt integration is particularly neat because prompts used by the Spark apps are extracted into a separate UI so users can view and modify them without having to dig into the (editable) React JavaScript code.
You can now run prompts against images, audio and video in your terminal using LLM
I released LLM 0.17 last night, the latest version of my combined CLI tool and Python library for interacting with hundreds of different Large Language Models such as GPT-4o, Llama, Claude and Gemini.
[... 1,399 words]Prompt GPT-4o audio. A week and a half ago I built a tool for experimenting with OpenAI's new audio input. I just put together the other side of that, for experimenting with audio output.
Once you've provided an API key (which is saved in localStorage) you can use this to prompt the gpt-4o-audio-preview model with a system and regular prompt and select a voice for the response.
I built it with assistance from Claude: initial app, adding system prompt support.
You can preview and download the resulting wav file, and you can also copy out the raw JSON. If you save that in a Gist you can then feed its Gist ID to https://tools.simonwillison.net/gpt-4o-audio-player?gist=GIST_ID_HERE (Claude transcript) to play it back again.
You can try using that to listen to my French accented pelican description.
There's something really interesting to me here about this form of application which exists entirely as HTML and JavaScript that uses CORS to talk to various APIs. GitHub's Gist API is accessible via CORS too, so it wouldn't take much more work to add a "save" button which writes out a new Gist after prompting for a personal access token. I prototyped that a bit here.
llm-whisper-api. I wanted to run an experiment through the OpenAI Whisper API this morning so I knocked up a very quick plugin for LLM that provides the following interface:
llm install llm-whisper-api
llm whisper-api myfile.mp3 > transcript.txt
It uses the API key that you previously configured using the llm keys set openai command. If you haven't configured one you can pass it as --key XXX instead.
It's a tiny plugin: the source code is here.
ChatGPT advanced voice mode can attempt Spanish with a Russian accent. ChatGPT advanced voice mode may refuse to sing (unless you jailbreak it) but it's quite happy to attempt different accents. I've been having a lot of fun with that:
I need you to pretend to be a California brown pelican with a very thick Russian accent, but you talk to me exclusively in Spanish
¡Oye, camarada! Aquí está tu pelícano californiano con acento ruso. ¿Qué tal, tovarish? ¿Listo para charlar en español?
How was your day today?¡Mi día ha sido volando sobre las olas, buscando peces y disfrutando del sol californiano! ¿Y tú, amigo, cómo ha estado tu día?
Pelicans on a bicycle. I decided to roll out my own LLM benchmark: how well can different models render an SVG of a pelican riding a bicycle?
I chose that because a) I like pelicans and b) I'm pretty sure there aren't any pelican on a bicycle SVG files floating around (yet) that might have already been sucked into the training data.
My prompt:
Generate an SVG of a pelican riding a bicycle
I've run it through 16 models so far - from OpenAI, Anthropic, Google Gemini and Meta (Llama running on Cerebras), all using my LLM CLI utility. Here's my (Claude assisted) Bash script: generate-svgs.sh
Here's Claude 3.5 Sonnet (2024-06-20) and Claude 3.5 Sonnet (2024-10-22):

OpenAI’s monthly revenue hit $300 million in August, up 1,700 percent since the beginning of 2023, and the company expects about $3.7 billion in annual sales this year, according to financial documents reviewed by The New York Times. [...]
The company expects ChatGPT to bring in $2.7 billion in revenue this year, up from $700 million in 2023, with $1 billion coming from other businesses using its technology.

Apple’s Knowledge Navigator concept video (1987) (via) I learned about this video today while engaged in my irresistible bad habit of arguing about whether or not "agents" means anything useful.
It turns out CEO John Sculley's Apple in 1987 promoted a concept called Knowledge Navigator (incorporating input from Alan Kay) which imagined a future where computers hosted intelligent "agents" that could speak directly to their operators and perform tasks such as research and calendar management.
This video was produced for John Sculley's keynote at the 1987 Educom higher education conference imagining a tablet-style computer with an agent called "Phil".
It's fascinating how close we are getting to this nearly 40 year old concept with the most recent demos from AI labs like OpenAI. Their Introducing GPT-4o video feels very similar in all sorts of ways.
Experimenting with audio input and output for the OpenAI Chat Completion API
OpenAI promised this at DevDay a few weeks ago and now it’s here: their Chat Completion API can now accept audio as input and return it as output. OpenAI still recommend their WebSocket-based Realtime API for audio tasks, but the Chat Completion API is a whole lot easier to write code against.
[... 1,522 words]ChatGPT will happily write you a thinly disguised horoscope
There’s a meme floating around at the moment where you ask ChatGPT the following and it appears to offer deep insight into your personality:
[... 1,236 words]openai/openai-realtime-console. I got this OpenAI demo repository working today - it's an extremely easy way to get started playing around with the new Realtime voice API they announced at DevDay last week:
cd /tmp
git clone https://github.com/openai/openai-realtime-console
cd openai-realtime-console
npm i
npm start
That starts a localhost:3000 server running the demo React application. It asks for an API key, you paste one in and you can start talking to the web page.
The demo handles voice input, voice output and basic tool support - it has a tool that can show you the weather anywhere in the world, including panning a map to that location. I tried adding a show_map() tool so I could pan to a location just by saying "Show me a map of the capital of Morocco" - all it took was editing the src/pages/ConsolePage.tsx file and hitting save, then refreshing the page in my browser to pick up the new function.
Be warned, it can be quite expensive to play around with. I was testing the application intermittently for only about 15 minutes and racked up $3.87 in API charges.
Anthropic: Message Batches (beta) (via) Anthropic now have a batch mode, allowing you to send prompts to Claude in batches which will be processed within 24 hours (though probably much faster than that) and come at a 50% price discount.
This matches the batch models offered by OpenAI and by Google Gemini, both of which also provide a 50% discount.
Update 15th October 2024: Alex Albert confirms that Anthropic batching and prompt caching can be combined:
Don't know if folks have realized yet that you can get close to a 95% discount on Claude 3.5 Sonnet tokens when you combine prompt caching with the new Batches API
Gemini 1.5 Flash-8B is now production ready (via) Gemini 1.5 Flash-8B is "a smaller and faster variant of 1.5 Flash" - and is now released to production, at half the price of the 1.5 Flash model.
It's really, really cheap:
- $0.0375 per 1 million input tokens on prompts <128K
- $0.15 per 1 million output tokens on prompts <128K
- $0.01 per 1 million input tokens on cached prompts <128K
Prices are doubled for prompts longer than 128K.
I believe images are still charged at a flat rate of 258 tokens, which I think means a single non-cached image with Flash should cost 0.00097 cents - a number so tiny I'm doubting if I got the calculation right.
OpenAI's cheapest model remains GPT-4o mini, at $0.15/1M input - though that drops to half of that for reused prompt prefixes thanks to their new prompt caching feature (or by half if you use batches, though those can’t be combined with OpenAI prompt caching. Gemini also offer half-off for batched requests).
Anthropic's cheapest model is still Claude 3 Haiku at $0.25/M, though that drops to $0.03/M for cached tokens (if you configure them correctly).
I've released llm-gemini 0.2 with support for the new model:
llm install -U llm-gemini
llm keys set gemini
# Paste API key here
llm -m gemini-1.5-flash-8b-latest "say hi"
OpenAI DevDay: Let’s build developer tools, not digital God
I had a fun time live blogging OpenAI DevDay yesterday—I’ve now shared notes about the live blogging system I threw other in a hurry on the day (with assistance from Claude and GPT-4o). Now that the smoke has settled a little, here are my impressions from the event.
[... 2,090 words]OpenAI DevDay 2024 live blog
I’m at OpenAI DevDay in San Francisco, and I’m trying something new: a live blog, where this entry will be updated with new notes during the event.
[... 68 words]Whisper large-v3-turbo model. It’s OpenAI DevDay today. Last year they released a whole stack of new features, including GPT-4 vision and GPTs and their text-to-speech API, so I’m intrigued to see what they release today (I’ll be at the San Francisco event).
Looks like they got an early start on the releases, with the first new Whisper model since November 2023.
Whisper Turbo is a new speech-to-text model that fits the continued trend of distilled models getting smaller and faster while maintaining the same quality as larger models.
large-v3-turbo is 809M parameters - slightly larger than the 769M medium but significantly smaller than the 1550M large. OpenAI claim its 8x faster than large and requires 6GB of VRAM compared to 10GB for the larger model.
The model file is a 1.6GB download. OpenAI continue to make Whisper (both code and model weights) available under the MIT license.
It’s already supported in both Hugging Face transformers - live demo here - and in mlx-whisper on Apple Silicon, via Awni Hannun:
import mlx_whisper
print(mlx_whisper.transcribe(
"path/to/audio",
path_or_hf_repo="mlx-community/whisper-turbo"
)["text"])
Awni reports:
Transcribes 12 minutes in 14 seconds on an M2 Ultra (~50X faster than real time).
OpenAI’s revenue in August more than tripled from a year ago, according to the documents, and about 350 million people — up from around 100 million in March — used its services each month as of June. […]
Roughly 10 million ChatGPT users pay the company a $20 monthly fee, according to the documents. OpenAI expects to raise that price by $2 by the end of the year, and will aggressively raise it to $44 over the next five years, the documents said.
Solving a bug with o1-preview, files-to-prompt and LLM.
I added a new feature to DJP this morning: you can now have plugins specify their middleware in terms of how it should be positioned relative to other middleware - inserted directly before or directly after django.middleware.common.CommonMiddleware for example.
At one point I got stuck with a weird test failure, and after ten minutes of head scratching I decided to pipe the entire thing into OpenAI's o1-preview to see if it could spot the problem. I used files-to-prompt to gather the code and LLM to run the prompt:
files-to-prompt **/*.py -c | llm -m o1-preview "
The middleware test is failing showing all of these - why is MiddlewareAfter repeated so many times?
['MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware5', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware2', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware5', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware4', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware5', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware2', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware5', 'MiddlewareAfter', 'Middleware3', 'MiddlewareAfter', 'Middleware', 'MiddlewareBefore']"The model whirled away for a few seconds and spat out an explanation of the problem - one of my middleware classes was accidentally calling self.get_response(request) in two different places.
I did enjoy how o1 attempted to reference the relevant Django documentation and then half-repeated, half-hallucinated a quote from it:
This took 2,538 input tokens and 4,354 output tokens - by my calculations at $15/million input and $60/million output that prompt cost just under 30 cents.
Notes on using LLMs for code
I was recently the guest on TWIML—the This Week in Machine Learning & AI podcast. Our episode is titled Supercharging Developer Productivity with ChatGPT and Claude with Simon Willison, and the focus of the conversation was the ways in which I use LLM tools in my day-to-day work as a software developer and product engineer.
[... 861 words]o1 prompting is alien to me. Its thinking, gloriously effective at times, is also dreamlike and unamenable to advice.
Just say what you want and pray. Any notes on “how” will be followed with the diligence of a brilliant intern on ketamine.
[… OpenAI’s o1] could work its way to a correct (and well-written) solution if provided a lot of hints and prodding, but did not generate the key conceptual ideas on its own, and did make some non-trivial mistakes. The experience seemed roughly on par with trying to advise a mediocre, but not completely incompetent, graduate student. However, this was an improvement over previous models, whose capability was closer to an actually incompetent graduate student.
Believe it or not, the name Strawberry does not come from the “How many r’s are in strawberry” meme. We just chose a random word. As far as we know it was a complete coincidence.

o1-mini is the most surprising research result I've seen in the past year
Obviously I cannot spill the secret, but a small model getting >60% on AIME math competition is so good that it's hard to believe

LLM 0.16.
New release of LLM adding support for the o1-preview and o1-mini OpenAI models that were released today.
Notes on OpenAI’s new o1 chain-of-thought models
OpenAI released two major new preview models today: o1-preview and o1-mini (that mini one is not a preview)—previously rumored as having the codename “strawberry”. There’s a lot to understand about these models—they’re not as simple as the next step up from GPT-4o, instead introducing some major trade-offs in terms of cost and performance in exchange for improved “reasoning” capabilities.
OpenAI says ChatGPT usage has doubled since last year. Official ChatGPT usage numbers don't come along very often:
OpenAI said on Thursday that ChatGPT now has more than 200 million weekly active users — twice as many as it had last November.
Axios reported this first, then Emma Roth at The Verge confirmed that number with OpenAI spokesperson Taya Christianson, adding:
Additionally, Christianson says that 92 percent of Fortune 500 companies are using OpenAI's products, while API usage has doubled following the release of the company's cheaper and smarter model GPT-4o Mini.
Does that mean API usage doubled in just the past five weeks? According to OpenAI's Head of Product, API Olivier Godement it does :
The article is accurate. :-)
The metric that doubled was tokens processed by the API.
OpenAI: Improve file search result relevance with chunk ranking (via) I've mostly been ignoring OpenAI's Assistants API. It provides an alternative to their standard messages API where you construct "assistants", chatbots with optional access to additional tools and that store full conversation threads on the server so you don't need to pass the previous conversation with every call to their API.
I'm pretty comfortable with their existing API and I found the assistants API to be quite a bit more complicated. So far the only thing I've used it for is a script to scrape OpenAI Code Interpreter to keep track of updates to their enviroment's Python packages.
Code Interpreter aside, the other interesting assistants feature is File Search. You can upload files in a wide variety of formats and OpenAI will chunk them, store the chunks in a vector store and make them available to help answer questions posed to your assistant - it's their version of hosted RAG.
Prior to today OpenAI had kept the details of how this worked undocumented. I found this infuriating, because when I'm building a RAG system the details of how files are chunked and scored for relevance is the whole game - without understanding that I can't make effective decisions about what kind of documents to use and how to build on top of the tool.
This has finally changed! You can now run a "step" (a round of conversation in the chat) and then retrieve details of exactly which chunks of the file were used in the response and how they were scored using the following incantation:
run_step = client.beta.threads.runs.steps.retrieve( thread_id="thread_abc123", run_id="run_abc123", step_id="step_abc123", include=[ "step_details.tool_calls[*].file_search.results[*].content" ] )
(See what I mean about the API being a little obtuse?)
I tried this out today and the results were very promising. Here's a chat transcript with an assistant I created against an old PDF copy of the Datasette documentation - I used the above new API to dump out the full list of snippets used to answer the question "tell me about ways to use spatialite".
It pulled in a lot of content! 57,017 characters by my count, spread across 20 search results (customizable), for a total of 15,021 tokens as measured by ttok. At current GPT-4o-mini prices that would cost 0.225 cents (less than a quarter of a cent), but with regular GPT-4o it would cost 7.5 cents.
OpenAI provide up to 1GB of vector storage for free, then charge $0.10/GB/day for vector storage beyond that. My 173 page PDF seems to have taken up 728KB after being chunked and stored, so that GB should stretch a pretty long way.
Confession: I couldn't be bothered to work through the OpenAI code examples myself, so I hit Ctrl+A on that web page and copied the whole lot into Claude 3.5 Sonnet, then prompted it:
Based on this documentation, write me a Python CLI app (using the Click CLi library) with the following features:
openai-file-chat add-files name-of-vector-store *.pdf *.txt
This creates a new vector store called name-of-vector-store and adds all the files passed to the command to that store.
openai-file-chat name-of-vector-store1 name-of-vector-store2 ...
This starts an interactive chat with the user, where any time they hit enter the question is answered by a chat assistant using the specified vector stores.
We iterated on this a few times to build me a one-off CLI app for trying out the new features. It's got a few bugs that I haven't fixed yet, but it was a very productive way of prototyping against the new API.
My @covidsewage bot now includes useful alt text. I've been running a @covidsewage Mastodon bot for a while now, posting daily screenshots (taken with shot-scraper) of the Santa Clara County COVID in wastewater dashboard.
Prior to today the screenshot was accompanied by the decidedly unhelpful alt text "Screenshot of the latest Covid charts".
I finally fixed that today, closing issue #2 more than two years after I first opened it.
The screenshot is of a Microsoft Power BI dashboard. I hoped I could scrape the key information out of it using JavaScript, but the weirdness of their DOM proved insurmountable.
Instead, I'm using GPT-4o - specifically, this Python code (run using a python -c block in the GitHub Actions YAML file):
import base64, openai client = openai.OpenAI() with open('/tmp/covid.png', 'rb') as image_file: encoded_image = base64.b64encode(image_file.read()).decode('utf-8') messages = [ {'role': 'system', 'content': 'Return the concentration levels in the sewersheds - single paragraph, no markdown'}, {'role': 'user', 'content': [ {'type': 'image_url', 'image_url': { 'url': 'data:image/png;base64,' + encoded_image }} ]} ] completion = client.chat.completions.create(model='gpt-4o', messages=messages) print(completion.choices[0].message.content)
I'm base64 encoding the screenshot and sending it with this system prompt:
Return the concentration levels in the sewersheds - single paragraph, no markdown
Given this input image:
Here's the text that comes back:
The concentration levels of SARS-CoV-2 in the sewersheds from collected samples are as follows: San Jose Sewershed has a high concentration, Palo Alto Sewershed has a high concentration, Sunnyvale Sewershed has a high concentration, and Gilroy Sewershed has a medium concentration.
The full implementation can be found in the GitHub Actions workflow, which runs on a schedule at 7am Pacific time every day.
