📁 Artifacts

A new Artifacts page brings together the files created in your conversations, in both the Web console and the desktop client:

Automatic collection: documents, web pages, images, and videos your Agents create show up in Artifacts automatically, on one timeline across all Agents.
Preview and trace back: filter by type or Agent, search, preview in place, and jump back to the conversation that produced a file (Thanks @rudycelekli #3732).
Pin and manage: pin, rename, or remove artifacts; a file card in a conversation takes you straight to it in Artifacts. The Artifacts page is hidden by default and can be turned on in the menu editor.

Custom menu: customize the groups, order, names, icons, and visibility of menu entries in the Web console and desktop client, with one shared configuration; artifacts and web links can be added as menu entries. See Custom Menu.
Token usage: each reply shows the tokens actually used in that turn, including cache hits. Thanks @Harbor404 (#3440)
Mermaid diagrams: Mermaid code blocks can switch to a rendered diagram, with zoom and full screen. Thanks @akushonkamen (#3620)
Faster long sessions: long sessions with many tool calls open faster.
Fixes: new session titles are no longer lost, and session actions on the default Agent no longer fail (Thanks @6vision #3625, #3617); settings saved together now all take effect, and workspace files are saved under the Agent they belong to (Thanks @aniruddhaadak80 #3454, #3488).
Collapsible sidebar: the Web console sidebar can collapse into an icon rail.

🔌 Open Agent Chat API

Agents are now available through a standard chat API, so you can connect third-party clients or call an Agent directly from your own systems:

Switch and key: turn the API on and generate an API key in one click on the Config page; the key is kept when the API is turned off. It can also be enabled through the config file or environment variables (Thanks @AaronZ345 #3068, @Bdysj #3342).
Agent and model selection: choose the Agent with agent_id and the model with model; without a model, the Agent’s default model is used.
Multi-turn conversations: by default the caller sends the full message history; with a conversation_id, the server keeps the history and only the latest message needs to be sent.
Complete output: streaming and non-streaming responses, including reasoning, token usage, and the tool call trace (Thanks @AaronZ345 #3068, @c020627 #3545, #3588).

📐 Prompt Caching & Context Cost

Claude prompt caching: the system prompt, tool definitions, and conversation prefix are cached, greatly improving cache hit rates and cutting token cost and latency. The cache lifetime is configurable via claude_cache_ttl.
Headroom after trimming: trimming the context now leaves headroom, so the prefix stays unchanged for the next several turns and long sessions keep hitting the cache.
Budget changes apply immediately: changes to the context budget and maximum steps apply to running Agents right away, without clearing the session.
Tool records kept in compaction: compacted turns keep a summary of their tool calls, so the model does not make up results (Thanks @tsumon #3634).
Fixes: messages arriving during compaction are no longer lost, and orphaned tool results are cleaned up more accurately (Thanks @c020627 #3518, @rudycelekli #3652, #3653).

🤖 Model Capabilities

Claude extended thinking: the connection stays open during long thinking, and when output stalls the request is retried at a lower thinking effort.
Custom headers: custom model providers support headers, with support for OpenCode Go.
Model discovery: when editing a model list, available models can be fetched from the provider automatically. Thanks @Harbor404 (#3441)
Reasoning content: both reasoning and thinking fields are supported, and an unclosed <think> tag no longer cuts off the reply (Thanks @a1094174619 #3601, @fly0sheep-1734 #3538).
Fallback models: the fallback model is reset at the start of each turn instead of staying in use.
OpenAI: improved handling of the Responses API and streaming responses (Thanks @rudycelekli #3659, #3660, #3661, #3663, @aniruddhaadak80 #3486).
Model list: fixed concurrent edits overwriting each other, custom primary models not taking effect, and capability tag matching (Thanks @rudycelekli #3577, #3662, #3666, @aniruddhaadak80 #3501).
Other providers: fixed compatibility issues with MiniMax, ModelScope, Baidu ERNIE, and Azure DALL·E (Thanks @aniruddhaadak80 #3464, #3476, #3479, #3507, #3512, @rudycelekli #3678).
Error handling: rejected requests are no longer resent, errors are recognized more accurately, and context usage shows real token counts (Thanks @c020627 #3442, #3443, #3445, @aniruddhaadak80 #3505, @6vision #3624).
Images: image generation keeps the original format and prompt, and image understanding on macOS no longer upscales images (Thanks @aniruddhaadak80 #3503, #3504, @rudycelekli #3568).

🧠 Memory & Knowledge Base

Knowledge editing and skill authoring: edit knowledge base pages directly in the console with the index updated automatically, write skills from scratch, and edit the files in a skill’s directory. Thanks @zkjqd (#3377)
Hit-based ranking: a new optional memory.hit_boost ranks frequently retrieved memories slightly higher. Off by default. Thanks @foreverjix (#3621)
Time decay: applies only to daily memory files, so dated knowledge base pages are no longer ranked down (Thanks @fly0sheep-1734 #3376).
Indexing: fixed content lost on very long lines, chunks exceeding the budget, and stale index entries after clearing notes (Thanks @fly0sheep-1734 #3585, @rudycelekli #3426, #3578, #3616).
Retrieval: improved full-text search fallback, Unicode keywords, and handling of invalid parameters and vectors (Thanks @aniruddhaadak80 #3480, #3481, #3482, #3483, @rudycelekli #3559, #3656, #3658).
Memory writes: failed writes can be retried, and session data from older versions can be imported (Thanks @aniruddhaadak80 #3406, @c020627 #3590, @rudycelekli #3387).
Knowledge base: fixed graph paths on Windows and documents with upper-case extensions not showing, and tightened import path validation (Thanks @Lesereingrape #3332, @rudycelekli #3612, #3649, #3651).

🤝 Multi-Agent Collaboration

Permissions and delegation: delegation and handoff keep the initiator’s permission mode, and the receiving Agent re-checks the delegation allowlist, depth, and wait time (Thanks @c020627 #3541, #3546, #3547, #3548, #3552).
Default Agent aliases: always resolved to the default Agent’s real ID (Thanks @c020627 #3553, #3554).
Team sessions: deleting a team session now removes it for every participant; fixed the model setting display and follow-up message delivery (Thanks @c020627 #3519, #3537, #3549, #3550, #3613).
Sub-agents: stopping a task also stops its sub-agents; fixed prompt parsing (Thanks @rudycelekli #3637, #3638, #3639).
Sessions and projects: fixed error handling for session settings and project paths (Thanks @c020627 #3551, @rudycelekli #3640, #3654).

🧩 Tools & Skills

File read/write: the original file is kept when a write fails; fixed line ending detection, concurrent edits overwriting each other, and argument parsing (Thanks @aniruddhaadak80 #3365, #3404, #3413, @rudycelekli #3525, #3531, #3563, #3566, #3567, #3667).

🛡 Security Hardening

Permissions: read-only mode now blocks git write operations it previously missed (Thanks @aniruddhaadak80 #3352, @drakeo338 #3357); dangerous operations such as command substitution, writes through arguments, and deleting the root directory are detected (Thanks @c020627 #3579, #3602, @aniruddhaadak80 #3506); outside full-access mode, the MCP config and session permissions cannot be changed.
