It also updates a DeepSeek Flash endpoint to the latest version, and adds Gemini 3.7 Flash.

We have released Calcish 1.13 with the following changes:

Improved integer log2 precision

Previously, the top-level log2 function returned an inexact big float result for integers perfectly representable as a power of two. For example, log2(2**128) returned 127.99999999999999999999999999999999, even though it should have returned 128. We fixed that.

New models

• OpenAI GPT-5.6 Sol, Terra and Luna (via OpenAI and OpenRouter APIs)
• Anthropic Fable 5, Claude 5, Sonnet 5 (via OpenRouter API)
• Gemini 3.6 Flash, 3.5 Flash-Lite (via Google and OpenRouter APIs)
• Kimi K3 (via OpenRouter API)
• GLM 5.2 (via OpenRouter API)
• MiniMax M3 (via OpenRouter API)

Removed models

• We removed some models that were deprecated and superseded by better ones.

We have published the Calcish documentation online at docs.calcish.com. This is the same documentation that is included in the Calcish app.

It includes thousands of pages of JavaScript help, describing the functions, methods, and features, including the ones that are available in the standard ECMAScript and the ones that are specific to Calcish.

Calcish documentation is a work of love. It was partially derived from TypeScript documentation, but we wanted to make it as easy to use as the legendary Turbo Pascal and Delphi documentation. The main differentiation from the awesome MDN is that our docs are not too wordy and have short examples even for the basic functions. It also has the minimal old school design.

You don’t have to use Calcish to use it: if you need a quick and basic JavaScript reference you’re in the right place. At the top right corner of the page, you can see whether the function or property is available in the standard ECMAScript or only in Calcish.

Check it out.

PS The initial online version doesn’t have search, which works nicely in Calcish, but powered by SQLite’s trigram search engine, so we couldn’t include it easily. We’ll work on that later.

We have released Calcish 1.11 with updated language models:

New models

• OpenAI GPT-5.5 (via OpenAI and OpenRouter APIs)
• DeepSeek V4 Pro and DeepSeek V4 Flash (via DeepSeek and OpenRouter APIs)
• Kimi K2.6 (via OpenRouter API)

Updated models

• Gemini 3 Flash is now available via OpenRouter API, along with Google API.

We have released Calcish 1.10!

New features

Image Asset preview

Asset cells with image files now show a preview of the image in the cell.

Duplicate codebook

You can now duplicate a codebook by right-clicking on it in the sidebar and selecting “Duplicate” or by clicking Edit → Duplicate Codebook. This creates a copy of the codebook with all its cells and content, allowing you to easily make variations or backups of your codebooks.

Other improvements and bug fixes

• Kimi K2.5 now uses the Nitro variant in the OpenRouter API, which makes it much faster.
• Fixed setting incorrect cell type for newly created cells in some cases.
• Fixed image asset token counting. Previously, Calcish overcounted tokens for image assets, which could push them out of the context window.

We have released Calcish 1.9!

New features

Image support for AI context

Asset cells with images are now used as part of the AI context with models that support images. This allows you to include images in your prompts and have the AI model understand and respond to them.

Model updates

Added:

• GPT-5.4
• GPT-5.4-mini
• GPT-5.4-nano
• GPT-5.3-codex
• Gemini 3.1 Flash-Lite
• MiniMax M2.5 (via OpenRouter API)

Removed old deprecated versions of models.

Other improvements

• Improved performance of AI response processing.
• Fixed duplicate system prompts.
• Fixed documentation formatting.

We have released Calcish 1.8!

New features

Added “Initial cell type” setting

When you created a new codebook or cleared the scratchpad, the first cell was always a code cell. Now you can change this behavior in settings and choose whether the first cell should be a code cell, an AI cell, or a text cell.

Documented new functions and classes

Some functions were not documented, as they were experimental and we didn’t want to commit to their names. Now the following functions and classes are documented:

createBitmap

Creates a Bitmap object from pixel data or a generator function. This function was previously called bitmap, but it has been renamed to createBitmap for clarity and to avoid confusion with the Bitmap class.

Example: createBitmap((i, x, y) => [x * 10, y * 10, 128, 255], 32, 32) creates a 32x32 bitmap with a gradient pattern.

qrcode function

Generates a QR code as a Bitmap object from the given text.

Example:

remoteTable function

Returns the first Table found on the specified web page.

It fetches the given URL, parses is as HTML, and creates a Table for the first <table> tag found on the page.

Example:

There’s also remoteTables function to fetch all tables from a single URL as an array of Table objects.

feedTable function

Fetches an RSS or Atom feed from a URL and returns it as a Table with article titles and dates.

There are also convenience functions:

• feedTable.hn() to fetch Hacker News feed
• feedTable.nyt() to fetch The New York Times feed
• feedTable.guardian() to fetch The Guardian world news feed.

Example:

interact function

Creates an interactive widget that allows you to adjust parameters and see live results.

Widget kind depends on the type of default parameter:

• string or number: Creates a text input
• [...strings]: Creates a dropdown picker (first item is default)
• [min, max] or [min, max, step]: Creates a numeric slider
• an object provides multiple parameters, each of which can be a string, number, or array (for dropdown and sliders). In this case, the function takes an object with parameter values instead of individual parameters.

Example:

Full change log:

• Added “Initial cell type” setting.
• Renamed bitmap function to createBitmap
• Documented createBitmap, qrcode, interact, loadURL, remoteTable, feedTable functions and Bitmap, URL, URLSearchParams classes.
• Improve the look of horizontal ruler in Markdown.
• Fixed AI cell icon position.
• Switched to Gemini 3.1 Pro model, as Google deprecated 3.0 Pro.
• Added Claude Opus 4.6 and Sonnet 4.6 models via OpenRouter.

We have released Calcish 1.7, which adds two new remote models (one of which can be used for free) and bug fixes.

Changes:

• Added openrouter:free — a free remote model via OpenRouter API. It’s not backed by a single model, but rather it is a router that selects free models at random from the models available on OpenRouter.
• Added openrouter:kimi-k2.5 — MoonshotAI’s Kimi K2.5 model via OpenRouter API.
• Fixed crash when stopping a pending AI request while waiting for response (#9).
• Fixed cursor jumping in the system prompt input (#8).
