Phone Agent New Setup + Upgrades
- Redesigned create & edit experience Creating and editing a phone agent is now a streamlined, modal-first flow — cleaner advanced settings, an improved workflow picker, voice selection, and a review step before you save.
New Phone Agent Setup:
Existing Agent Edit:
- Post-call summary emails Enable summary emails on your agent to get a recap delivered after every call.
- Smarter call handling If a caller goes silent, the agent now politely re-engages before ending the call, and we fixed an issue where the first word of the agent's greeting could be clipped. Call logs now show times in your local timezone with clearer status badges.
- Caller Blocklist Phone agents can now block spam and unwanted callers. Manage blocked numbers from the new Blocklist Manager in your agent's settings, or block a number in one click straight from the call logs. Blocked callers are screened out before the AI engages, and their calls are automatically labeled with a new Blocked status in your logs.
Artifact Upgrades
- Public artifact links — share artifacts with anyone, no Hatz login required. Generate a public link and recipients get a secure, view-only page; rotate or revoke the link at any time.
Account Teams
- Account Teams let you limit which members of your organization can access which customer tenants. When Account Team enforcement is on, a team member who is not an admin can only open and manage the tenants they have been added to. This is useful when different people own different books of business and you want each person to see only their own accounts.
New LLM
- Grok 4.5 is now available in the model catalog
"SpaceXAI's smartest model built to excel at coding, agentic tasks, and knowledge work. It's our strongest model ever and was trained alongside Cursor. Grok 4.5 was trained on datasets spanning knowledge in coding, science, engineering, and math. With both intelligent and efficient reasoning, Grok 4.5 excels at real engineering tasks and exceeds comparable leading models at these tasks."
- SpaceXAIImprovements
- Workflows with expired or broken integration credentials are now clearly flagged reconnect required, and triggers can no longer dispatch through unauthorized connections.
- Items shared by a group editor are now visible to all group members.
- Fixed: workflow canvas appearing empty
- Custom platform roles now correctly see the Integrations & Tools page.
- New guardrails prevent publishing apps or workflows pointed at retired models, and existing apps and workflows referencing a retired model are automatically healed to its successor — nothing silently breaks when a model is sunset.
- File download links in chat output now work reliably, long-running code executions recover from sandbox timeouts, and deep research no longer hangs on long runs.

New LLMs
- Fable 5 (Anthropic) has been re-enabled
"Claude Fable 5 introduces our 5th model generation for your most ambitious work. Tackle days-long, complex, and asynchronous tasks previous models couldn't sustain." — Anthropic
Claude Fable 5 is Anthropic's most capable generally available model, built for long-horizon coding projects, deep research, and multi-stage enterprise workflows. It can plan across stages, delegate to sub-agents, and check its own work — including using vision to evaluate outputs against the original goal. It's state-of-the-art on coding, knowledge work, and computer use.
⚠️ Note: Claude Fable 5 consumes significantly more credits than other models — approximately 12x our baseline. It also requires special 30-day data retention for safety monitoring. Learn more about Fable's data retention practices.
- GPT-5.6 Sol (OpenA)
- GPT-5.6 Terra (OpenAI)
- GPT-5.6 Luna (OpenAI)
"GPT‑5.6 Sol is our strongest model yet. To give a preview of model performance, we share a set of evaluations highlighting improved agentic capabilities in coding, biology, and cybersecurity" - OpenAI
Artifacts
- An artifact is a reusable item created by AI and distributed through Workshop, group shares, or public links.
- Ask Hatz to build a report, slide deck, tracker, or interactive web page, and it's created as an artifact you can preview and refine right in the conversation.
- Creates Code, PDF, DOCX, PPTX, and HTML
Compliance & Logs
- Admins can review a complete, searchable record of every AI interaction in their organization.
- See each invocation — the user, their tenant, the model used, and the chat, app, or agent it came from — then filter by user or date range and open any entry to inspect its content.
- Records can be exported for audits and reporting.
- MSP Admins have full control over who has access to this feature and can choose whether or not to enable it per tenant.
Search Hatz Docs From Hatz Chat
- Hatz users can now reach Hatz's own knowledge and capabilities through MCP, and without enabling tools.
- Get real time answers based on searches of our up to date documentation.
Improved
Phone agent improvements:
- Phone agents now report the correct, local time to callers
- Natural language interruptions - callers can now speak over the agent and it intelligently classifies whether that speech is a real interruption, so conversations feel more natural.
New
- Phone Agents now recognize and greets returning callers by name, using context from prior calls. Only the caller name is retained between calls from the same phone number. Can be enabled or restricted by Admins.
- Admins can now set a maximum call length for their AI phone agents, giving them control over how long the AI stays on a call. When enabled, the agent gracefully wraps up the conversation with a friendly message before the time limit is reached, then ends the call. This feature is off by default and only affects the AI portion of a call — calls that have been transferred to a live person are never cut off.
- Admins can now set business hours for a phone agent (days, hours, and timezone). Outside of those hours, the agent switches to after-hours mode — it can still chat and take a message for follow-up, but it won't transfer the caller.
- You can now use one of your existing agents as the brain behind a phone agent instead of building a phone agent from scratch. If an agent is not eligible to be selected for the phone agent, the reason is displayed.
Improved
- When you don't manually choose a model (you're on "Auto-LLM") the system decides which underlying model handles your request based on what you're asking for. We swapped in newer, better-performing models behind that automatic selection for Lite and Performance modes, so you get better output quality automatically.
- If an agent hits a step it can't get past, it now stops itself and tells you specifically what it was trying to do and where it got stuck instead of quietly retrying in the background indefinitely.
New
- Claude Sonnet 5 is now available in the model selector for chat, apps, agents, and workflows.
Sonnet 5 narrows the gap: its performance is close to that of Opus 4.8, but at lower prices. It’s a substantial improvement over its predecessor, Sonnet 4.6, on important aspects of agentic performance like reasoning, tool use, coding, and knowledge work.
- Anthropic
Scores for Sonnet 5 on a variety of evaluations compared to those of Sonnet 4.6 and Opus 4.8 (a more generally capable model, for reference).
- Anthropic-Seven new LLMs added to the model selector. These models are US-based, lightning-fast, and built for efficiency — delivering powerful AI performance with low credit usage.

- The Microsoft 365 integration got several upgrades: browse and search calendar events across any date range (previously capped at about a week or 50 events), filter email search by date range, read/unread status, importance, and attachments, create and move Outlook mail folders, and read and search from shared mailboxes you have access to.
New
- Admins can restrict which AI models are available to each role. From the Customize Roles page, limit the models a role is permitted to use. MSP admins can also set model restrictions on tenant creation templates, so new tenants start with the right policy already applied.
- Workflows can now use a saved agent as an LLM step. From the workflow builder, open the model picker on any LLM step and select one of your agents instead of a base model. The agent runs with its full configuration — system prompt, tools, and model settings — so you can compose agents into multi-step automations without rebuilding their behavior from scratch.
- Phone agents support warm transfers. When enabled, instead of dropping a caller directly to a department, the agent dials the destination first, briefs the recipient on the call, and lets them accept or decline before bridging. If the recipient declines or doesn't answer, the agent returns to the caller with a take-a-message offer. Turn it on from Call Settings on any phone agent with transfer destinations configured.
- MSP admins can now set a monthly extra usage budget per tenant. When a tenant exhausts their package credits, instead of hitting a hard block they draw from the extra usage budget and keep working. Set the threshold in dollars or credits from the tenant overview — once the extra budget is exhausted the tenant falls back to Lite mode until the limit is raised or the month resets. Tenants whose MSP hasn't enabled extra usage yet can request it directly, which sends a notification to their admin.
New
- Phone agents can now route callers to the right team — by reading the conversation, or by keypad. Configure a list of up to 10 departments — each with a label, phone number, and description — and choose how routing works. In agent-routed mode, the agent reads the conversation and transfers to whichever department fits the caller's need, using your descriptions to decide. In caller presses a key mode, the agent presents a menu ("press 1 for Sales, press 2 for Billing…") and routes on the digit the caller enters. Your phone agent can now act as a full front-line router. Callers reach the right team on the first transfer, without a human triaging calls in the middle.
- From the Integrations & Tools settings page, admins can now enable or disable built-in tools the same way they control integrations. Set your policy at the MSP level and it applies to all managed tenants. Tenant admins can restrict further from there. Role-based controls let you go even more granular — and if you're using tenant creation templates you can set your built-in tool policy in so every new tenant starts with the right defaults already applied.
In accordance with the US Government directive to disable Claude Fable 5, the model has been set to a disabled state in Hatz AI.
Access to all other Anthropic models available in Hatz will not be affected.
New
- From the Call Settings on any phone agent, select a workflow to run automatically at the end of every call. Use it for post-call summaries, CRM updates, ticket creation, or any follow-on automation you'd otherwise do by hand.
- Re-run a workflow from any step. When reviewing a completed workflow run, you can now re-run from a specific step and pre-fill previous step results — so you can iterate on one part of a workflow without re-running everything from scratch. Only the steps you clear will re-run with no credits used on steps that don't need to change.
- Admins can now control which integrations and custom MCP servers each role can access. From the Customize Roles page, configure integration access per standard role (Helpdesk, Billing Manager, etc.) or custom role. Role restrictions work within your MSP and tenant policy ceiling — a role can restrict access further, but never grant past what's already denied above it.
- MSP admins can now set integration and custom MCP access defaults directly on tenant creation templates. New tenants provisioned from that template start with those restrictions already applied as their own editable policy — no manual setup required per tenant.
- Read and attach files in Outlook. The Microsoft 365 integration now supports email attachments — agents can list and download attachments from emails, and can attach Hatz-managed files when composing or replying.
- 15 new Hatz Official workflows. Browse 15 new ready-to-use workflows in the Workshop under the Hatz Official filter in the Community.
Fixed
- Fixed an issue where occasionally image generation models incorrectly showed a Code Execution error when asked to generate an image. Image generation doesn't require Code Execution and the error was a false positive.
Claude Fable 5 is added to the model selector for chat, apps, agents, and workflows.

New
- From the new Integrations & Tools settings page, admins can enable or disable any Hatz integration — controlling exactly which integrations are available to their managed tenants.
- The Integrations & Tools settings page now shows the full list of Hatz built-in tools, giving admins full visibility into what's available in the workspace.
- MSP Admins and Client Admins can now view, enable, disable, and delete custom MCP servers from the Integrations & Tools settings page per tenant. Each server shows its connection health status so you can quickly spot and clean up anything that's broken or no longer needed. Custom MCP management has moved here from Org Settings, where previously only a single on/off toggle existed for all servers.
- Browse templates curated by the Hatz team using the Hatz Official filter in the Workshop alongside community contributions. Filter to Hatz Official to find verified, ready-to-use templates fast.
- Delete AI Generated files you no longer need directly from the files panel in any chat conversation. Open the menu on any Generated File and select Delete to remove it.
- XLSM, VTT, and PCAP files are now supported in Hatz. Excel macro-enabled workbooks, video subtitles, and network capture files are all fair game.
Improved
- The Microsoft 365 integration now takes action, not just reads. Compose, reply to, and draft emails with attachments. Triage your inbox — move, flag, and forward across folders. Find available times across attendees with the scheduling assistant, create meetings with Teams links and recurrence, edit and reschedule events, and respond to invites. In Teams, post messages to chats and channels, manage channels, look up people across your org, and set your presence. In OneDrive, create folders and move or copy files. When an agent composes on your behalf, it saves a draft — nothing sends without you.
- ConnectWise Manage integration can now pull a full audit trail for any record — see the complete change history for Tickets, Configurations, Purchase Orders, Product Catalog items, and Expenses.
- The Autotask integration has been improved to allow agents to run multiple tools simultaneously without running into Autotask's API rate limits. Previously, parallel tool calls would stall as they competed for Autotask's per-endpoint limits — now they're automatically coordinated so your work runs through without interruption.
