Pi 0.79.1

New version of pi. Download from npm or view release on GitHub.

New Features

  • Claude Fable 5 - Claude Fable 5 is now available on the Anthropic and Amazon Bedrock providers, with adaptive thinking and xhigh effort support.
  • Prompt template defaults - Prompt templates can use default positional arguments such as ${1:-7} for optional values. See Prompt Template Arguments.

Release notes

Pi 0.77.0

New version of pi. Download from npm or view release on GitHub.

New Features

  • Claude Opus 4.8 support - Adds Anthropic Claude Opus 4.8 metadata and updates Opus adaptive-thinking coverage.
  • Selective tool disablement - --exclude-tools / -xt disables specific built-in, extension, or custom tools while leaving the rest available. See Tool Options.
  • Headless Codex subscription login - /login can use device-code auth for ChatGPT Plus/Pro Codex subscriptions. See Subscriptions and OpenAI Codex.
  • Streaming-aware extension input - extensions can distinguish idle prompts, mid-stream steers, and queued follow-ups with InputEvent.streamingBehavior. See Input Events.

Added

  • Added --exclude-tools / -xt to disable specific built-in, extension, or custom tools while leaving the rest available (#5109).
  • Added OpenAI Codex subscription device-code login as a selectable headless alternative while keeping browser login as the default (#4911 by @vegarsti).

Release notes

Pi 0.76.0

New version of pi. Download from npm or view release on GitHub.

New Features

  • Explicit session IDs for automation - --session-id <id> lets scripts create or resume an exact project-local session. See Sessions.
  • RPC bash output can stay out of model context - RPC clients can pass excludeFromContext to bash for commands whose output should not be sent with the next prompt. See RPC mode.
  • More predictable provider retries and timeouts - Codex WebSocket/SSE waits are bounded, and retry.provider.maxRetries controls provider retries instead of hidden SDK defaults. See Retry settings.
  • Better terminal editing across environments - Apple Terminal Shift+Enter, Windows/JetBrains capability detection, and Unicode-aware word navigation improve interactive editing. See Terminal setup and Keybindings.

Added

  • Added --session-id to let CLI callers use an exact project-local session ID, creating it if missing (#4874).
  • Added excludeFromContext flag to the bash RPC command for parity with the internal executeBash API (#5039).

Release notes

Pi 0.75.5

New version of pi. Download from npm or view release on GitHub.

New Features

  • Cleaner read tool output - Collapsed read tool cards now show only the read line by default, while Ctrl+O still expands the full file content.
  • Faster file tools on Windows - Built-in file tools now use async filesystem operations during streaming, and image resizes run off the main TUI thread in a worker.
  • More reliable package updates - pi update and git package installs now reconcile pinned git refs and keep package settings intact. See Packages.
  • Custom Anthropic-compatible adaptive thinking - Custom provider model configs can opt into adaptive-thinking Claude behavior with compat.forceAdaptiveThinking. See Custom providers and Models.

Added

  • Added compat.forceAdaptiveThinking support to custom Anthropic-compatible model configuration docs and validation (#4797 by @mbazso).
  • Added a standard unified patch to edit tool result details for SDK consumers (#4821).
  • Added a Codex subscription login method selector with device-code auth for headless environments.

Changed

  • Changed collapsed read tool cards to show only the read line until expanded (#4916).
  • Replaced the inherited optional koffi dependency for Windows VT input with a tiny vendored native helper, reducing install size while preserving Shift+Tab handling (#4480).
  • Changed the root development install documentation to use npm install --ignore-scripts (#4868).

Release notes

Pi 0.75.4

New version of pi. Download from npm or view release on GitHub.

New Features

  • Hardened npm install and release path - Pi now ships the CLI with a generated shrinkwrap for transitive dependencies, blocks accidental lockfile changes, verifies dependency pinning and lifecycle-script allowlists in checks, disables lifecycle scripts for self-update and local release installs where supported, and smoke-tests isolated npm and Bun installs before release. See Supply-chain hardening.

Added

  • Added interactive update notes after pi update runs, so users can see the installed version's changelog before continuing (#4724 by @mitsuhiko).
  • Exported image resize utilities from the package root for SDK consumers (#4775 by @xl0).

Changed

  • Changed source syntax to avoid TypeScript constructs that require JavaScript emit, keeping core sources compatible with Node.js strip-only TypeScript checks.
  • Removed web UI workspace references from the CLI package and dropped the package-level development watch script.
  • Published npm installs now include an npm-shrinkwrap.json to lock transitive dependencies for the CLI package.
  • Improved terminal theme detection for light/dark and truecolor handling.
  • Changed self-update package-manager commands to disable lifecycle scripts during reinstall.

New version of pi. Download from npm or view release on GitHub.

Fixed

  • Fixed Bun-compiled release binaries failing to start when Bun's built-in undici shim lacks npm undici's install export (#4661 by @dmasiero).
  • Fixed Xiaomi MiMo generated model metadata to replay assistant tool-call messages with reasoning_content for thinking-mode multi-turn requests, inherited from @earendil-works/pi-ai (#4678).
  • Fixed Windows external editor handoff so vim/nvim can receive input after opening from the TUI (#4612).
  • Fixed Windows npm self-updates to move loaded native dependency packages out of the active install before reinstalling pi (#4157).
  • Fixed pi update --self detection for pnpm v11 global installs whose package path resolves through the pnpm store (#4647).
  • Fixed Windows pnpm self-updates to resolve pnpm command shims and run through pnpm instead of requiring manual updates (#4157).
  • Fixed Windows npm-family command execution to use cross-spawn instead of parsing .cmd shim internals (#4665).

Release notes

Pi 0.73.1

New version of pi. Download from npm or view release on GitHub.

New Features

  • Self-update support for the npm scope migration: pi update --self now supports the upcoming package rename from @mariozechner/pi-coding-agent to @earendil-works/pi-coding-agent. After the new package is published, existing global installs can update through the normal self-update flow; pi will uninstall the old global package and install the package name returned by the version check endpoint.
  • Interactive OAuth login selection: OAuth providers can now present multiple login choices in /login, enabling provider-specific interactive authentication flows. See Providers.
  • JSONC-style models.json parsing: models.json now allows comments and trailing commas, making custom provider and model configuration easier to maintain. See Providers and Custom Providers.

Added

  • Added interactive login selection support so OAuth providers can present multiple login choices (#4190 by @mitsuhiko).

Changed

  • Changed pi update --self to honor the active package name returned by the Pi version check endpoint, defaulting to the current package when omitted and uninstalling the old global package before installing a renamed package.
  • Changed extension loading to use upstream jiti 2.7 instead of the @mariozechner/jiti fork (#4244 by @pi0).
  • Changed models.json parsing to allow comments and trailing commas (#4162 by @julien-c).

Release notes

Pi 0.73.0

New version of pi. Download from npm or view release on GitHub.

New Features

  • Xiaomi MiMo API billing and regional Token Plan providers - xiaomi now uses API billing, with separate xiaomi-token-plan-{cn,ams,sgp} providers. See docs/providers.md#api-keys and README.md#providers--models. (#4112 by @Phoen1xCode)
  • Incremental bash output streaming - Bash tool output now appears while commands run instead of only after completion. (#4145)
  • Compact read rendering - Interactive read output for Pi docs, context files, and skills is collapsed by default and shows selected line ranges.

Breaking Changes

  • Switched the built-in xiaomi provider from Token Plan AMS to Xiaomi's API billing endpoint, and renamed its /login display from "Xiaomi MiMo Token Plan" to "Xiaomi MiMo". XIAOMI_API_KEY now refers to the API billing key from platform.xiaomimimo.com. Users on Token Plan should switch to the appropriate xiaomi-token-plan-* provider and set the corresponding env var (#4112 by @Phoen1xCode).

Added

  • Added three Xiaomi MiMo Token Plan regional providers visible in /login: xiaomi-token-plan-cn (XIAOMI_TOKEN_PLAN_CN_API_KEY), xiaomi-token-plan-ams (XIAOMI_TOKEN_PLAN_AMS_API_KEY), xiaomi-token-plan-sgp (XIAOMI_TOKEN_PLAN_SGP_API_KEY). Each defaults to mimo-v2.5-pro (#4112 by @Phoen1xCode).

Changed

  • Changed read tool rendering to collapse Pi documentation, AGENTS/CLAUDE context files, and SKILL.md contents by default in interactive output.

Pi 0.72.0

New version of pi. Download from npm or view release on GitHub.

New Features

Breaking Changes

  • Replaced compat.reasoningEffortMap in models.json and pi.registerProvider() model definitions with model-level thinkingLevelMap (#3208). Migration: move old mappings from compat.reasoningEffortMap to thinkingLevelMap. Use string values for provider-specific thinking values and null for unsupported pi levels that should be hidden and skipped by cycling. See docs/models.md#thinking-level-map and docs/custom-provider.md.

Added

  • Added Xiaomi MiMo Token Plan provider support with XIAOMI_API_KEY, default model resolution, /login display support, and provider documentation (#4005 by @Phoen1xCode).
  • Added model-level thinkingLevelMap support in models.json and pi.registerProvider(), allowing models to expose only the thinking levels they actually support (#3208).
  • Added shouldStopAfterTurn agent loop callback for post-turn stop control, inherited from @mariozechner/pi-agent-core. See packages/agent/README.md.

Pi 0.71.1

New version of pi. Download from npm or view release on GitHub.

Added

  • Added websocket-cached to the transport setting options for the OpenAI Codex provider used with ChatGPT subscription auth. This keeps the same WebSocket open for a session and, after the first request, sends only the new conversation items instead of resending the full chat history when possible.
