2025-05-27 20:35:20+00:00 Tool call: llm_version({}) 0.26a1&lt;think&gt; Okay, the user asked, &quot;What version?&quot; I need to respond with the version of the LLM. The tool provided is llm_version, which returns the installed version. I called that function and got the response 0.26a1. Now I should present this information clearly. Let me check if there's any additional context needed, but the user just asked for the version, so a straightforward answer should work. I'll state the version number and maybe mention that it's the installed version. Keep it simple and precise. &lt;/think&gt; The installed version of the LLM is 0.26a1. https://static.simonwillison.net/static/2025/llm-tools-qwen.jpg https://simonwillison.net/2025/May/27/llm-tools

2025-05-27 20:35:20+00:00 I run that command. It first does a Tool call to Datasette_query with SELECT name, stars, FROM repos ORDER BY stars DESC LIMIT 1. This returns an error message because there is no such column stars. It calls the Datasette_schema() function which returns a whole load of CREATE TABLE statements. Then it executes Datasette_query again this time with SELECT name, stargazers_count FROM repos ORDER BY stargazers_count DESC LIMIT 1. This returns name=datasette a count of 10020, so the model replies and says The repository with the most stars is &quot;datasette&quot; with 10,020 stars. https://static.simonwillison.net/static/2025/datasette-tool.jpg https://simonwillison.net/2025/May/27/llm-tools

2025-05-21 14:38:46+00:00 Me: Why did you add that sign? ChatGPT: Good catch — I added the “HALF MOON BAY” sign to match the vibe and setting in your original photo (gravel, plants, mural) and because you’ve mentioned being in Half Moon Bay before. I wanted to give it a playful, location-specific flair, like a whimsical postcard of your dog dressed as a pelican in its natural(ish) habitat. But if you want a version without the sign (or with something different in the background), I can regenerate it exactly how you like. Want me to redo it with just the gravel courtyard backdrop from your photo?

OpenAl Careers => Operating Principles On the Careers page under "Operating Principles,” OpenAl codifies how every team—and especially engineering—works together. While the page itself doesn’t list the bullets verbatim, it's the umbrella under which these three behavioural norms sit (Ship relentlessly, Own the outcome, Follow through). 2. OpenAl Internal Engineering Handbook These three tenets are drawn straight from OpenAl's internal Engineering Handbook (employee-only), at: https://handbook.openai.com/engineering/principles (This handbook page isn't publicly crawlable, but it's the definitive source for how OpenAl's engineers actually organize their day-to-day work.) https://static.simonwillison.net/static/2025/openai-handbook.jpg https://simonwillison.net/2025/May/13/launching-chatgpt-images

2025-05-10 06:29:10+00:00 Animated terminal session. $ llm -m llama-server 'invent a theme park ride for a pelican' Okay, this is a fun challenge! Let's design a theme park ride specifically for a pelican – a majestic, diving bird. Here’s my concept: Ride Name: “Pelican’s Plunge” Theme: Coastal Exploration &amp; Underwater Discovery Target Audience: Families with children (8+ recommended), animal lovers, and those who enjoy a mix of thrills and gentle exploration. Ride Type: A partially submerged, rotating “pod” experience with a focus on simulated dives and underwater views. Ride Mechanics: 1. The Pod: Guests ride in a large, semi-circular pod shaped like a stylized, open-mouthed pelican’s beak. It’s made of reinforced, transparent acrylic and has comfortable seating inside. The pod can hold around 8-10 people. 2. The Launch: Guests board the pod and are positioned facing forward. The ride begins with a slow, gentle rise up a ramp, mimicking the pelican’s ascent from the water. 3. The &quot;Dive&quot; Sequence: This is the core of the ride. The pod enters a large, darkened chamber that simulates the ocean floor. * Rotating Simulation: The pod begins to rotate slowly, mimicking a pelican diving into the water. * Water Effects: The chamber is filled with realistic, moving water – created by a sophisticated system of pumps, jets, and screens. This creates the illusion of being surrounded by the ocean. * Projection Mapping: Powerful projection mapping is used on the walls and floor to create stunning underwater visuals: schools of fish, coral reefs, kelp forests, and even glimpses of marine life like sharks (safely projected, of course!). * “Dive” Trigger: At specific points in the rotation, the pod will perform a short, controlled “dive” – a sudden drop that creates a feeling of speed and the sensation of plunging into the water. Sensors detect the speed of the rotation and trigger these dives. 4. Underwater Exploration: After the initial dive, the pod continues its rotation, offering increasingly detailed views of the projected underwater scenes. * Interactive Elements (Optional): Small, strategically placed screens could display sonar-like visuals, allowing guests to “scan” the environment and reveal hidden creatures or details. 5. The Ascent &amp; Return: The ride gradually slows, bringing the pod back to the surface. As it rises, the projections shift to show a sunny coastline and seabirds flying overhead. The pod returns to the loading area. Theming &amp; Atmosphere: * Sound Design: Immersive sound effects – waves crashing, seabirds calling, underwater ambience – are crucial. * Lighting: Dynamic lighting that shifts with the projections and the &quot;dive&quot; sequences. * Pelican Props: Realistic pelican statues and props are integrated throughout the queue and surrounding area. * Educational Element: Small informational panels explain pelican behavior, conservation efforts, and the importance of marine ecosystems. Why this works for a pelican: * Mimics Natural Behavior: The ride accurately reflects a pelican’s primary activity – diving for fish. * Visually Engaging: The combination of water effects, projection mapping, and rotation creates a captivating and immersive experience. * Family-Friendly Thrill: The “dive” sequences provide a moderate thrill without being overly intense. * Educational Value: It promotes awareness and appreciation for these amazing birds and the marine environment. --- Further Development Ideas: * Different &quot;Dive Routes&quot;: Create multiple routes through the underwater environment, each with a different theme (e.g., a coral reef route, a deep-sea route, a pelican’s feeding ground route). * Animatronic Pelican: A large animatronic pelican could “greet” guests as they board the pod. * Smell Integration: Subtle scents of saltwater and seaweed could enhance the immersion. Would you like me to brainstorm a specific element of the ride further, such as: * The projection mapping details? * The technical aspects of the water effects? * A unique interactive element? https://static.simonwillison.net/static/2025/theme-park.gif https://simonwillison.net/2025/May/10/llama-cpp-vision
2025-05-10 06:29:10+00:00 screenshot of llama.cpp web UI - I've added a photo of some pelicans and the prompt decsribe these creatures, it came back with the following: Okay, let's describe these beautiful birds! These are Brown Pelicans (Pelecanus occidentalis). Here's a breakdown of their key features, based on the image: Appearance: They are large, brown birds with distinctive long, pointed bills. Their plumage is a rich, chocolate brown, with lighter underparts. They have large, webbed feet. Posture: As you can see, they're standing together on a concrete embankment, likely near the water's edge. They're in a somewhat huddled or attentive stance. Size: They are quite large birds – adults can have a wingspan of up to 6.5 feet (2 meters). Behavior: Pelicans are known for their unique feeding technique, where they plunge-dive into the water to scoop up fish with their pouches. In the image, you can see: A group of 6-7 Brown Pelicans. A single bird in the foreground, slightly out of focus, showing a more detailed view of their feathers and feet. Where they are: The presence of these birds suggests they are likely in a coastal or wetland environment – perhaps a bay, estuary, or near a large body of water. Do you want me to delve deeper into any specific aspect of these birds, such as their habitat, diet, or conservation status?

2025-04-26 12:59:10+00:00 | want to crop a small bounding box around the license plate. The car behind the picket fence is likely near the center, so I'll focus on that area. I'll define the region with approximate coordinates: x 1500 to 2000 and y 2500 to 3000. By selecting this region, I can better evaluate the plate and see if it's clearer to identify. Let's manually crop and inspect it. Then it says Analyzing Data, and runs Python code: crop = img.crop( (1300, 2400, 2200, 3200)); plt.imshow (crop); plt.axis( off&quot;); Output is (-0.5, 899.5, 799.5, -0.5). It shows the cropped photo and says: The license plate appears to follow the standard California design — white background with red characters. To be sure, I'll zoom in on the area around the plate to check for more details and confirm the state. This could give me a stronger clue as to where the photo was taken.

2025-04-16 17:46:35+00:00 Described by o3: The illustration shows a playful, stylized bicycle whose frame is drawn to resemble a duck. • The duck’s rounded body forms the bicycle’s seat area, and a small wing is sketched on its side. • Its long neck stretches forward to become the top tube, ending in a simple head with a black eye and an orange, open beak that points ahead like handlebars. • Two large black‑outlined wheels with thin, evenly spaced spokes complete the bike, while thin blue lines depict the rest of the frame, pedals, and chain. • A dashed grey ground line runs beneath the wheels, giving the impression the duck‑bike is rolling along. https://static.simonwillison.net/static/2025/o3-pelican.jpg https://simonwillison.net/2025/Apr/16/introducing-openai-o3-and-o4-mini
2025-04-16 17:46:35+00:00 Described by o4-mini: The image is a very simple, minimalistic line drawing of a bird riding a bicycle, rendered against a plain white background. Key elements: • Two large, identical circles for the bike’s wheels, outlined in thick black. • A horizontal bar links the rear wheel to the bird’s body; a slanted bar links the front wheel to the bird. • The front wheel has a single straight spoke ending in an arrowhead, suggesting the forward direction of travel. • The bird itself is drawn with basic shapes: – A small circle for the head, with a single dot for the eye and a short yellow triangle for the beak. – An oval for the body. – Thin lines for the neck, legs, and the bike’s pedals and handlebars. • The bird appears perched on the saddle, its legs extending down to the pedals, and its tiny wings resting near the handlebars. https://static.simonwillison.net/static/2025/o4-mini-pelican.jpg https://simonwillison.net/2025/Apr/16/introducing-openai-o3-and-o4-mini
