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.
"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."
— AnthropicClaude 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.
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.
New
- Tenant Workspace Templates. MSP admins can now define a default configuration for every new tenant — including which AI model they start on, which models are available or blocked, whether memory, personalization, and subagents are enabled, and which apps and agents are pre-loaded. Create multiple templates for different customer types and choose the right one at provisioning time. Set it once, and every new tenant starts from the same baseline.
- Share apps, agents, and workflows with all current and future tenants in one toggle. From the Share Settings panel on any Workshop item, turn on Share with all current and future tenants and you're done. New tenants are automatically granted access the moment they're provisioned — no manual assignment required.
- Control who can edit, not just who can access. Enabling Allow internal organization to edit gives Workshop creation rights to internal team members — not tenant users — to make changes to a shared item. Opt-in per item, so you stay in control of what's editable and what's locked down.
- LLM Gateway expanded to include Anthropic messages compatibility. If you're already using the Anthropic SDK or building with Claude, you can now send requests in the Anthropic messages format directly to Hatz. Your calls route through Hatz's model system — usage tracked, billed, and governed the same way as everything else. It's not a full Anthropic API passthrough; it covers the messages endpoint.
- New LLM Opus 4.8 added to the model selector for chat, apps, agents, and workflows.
One of the most prominent improvements in Opus 4.8 is its honesty. We train all our models to be honest—for instance, to avoid making claims that they can’t support. But a general problem with AI models is that they sometimes jump to conclusions, confidently claiming to have made progress in their work despite the evidence being thin. Early testers report that Opus 4.8 is more likely to flag uncertainties about its work and less likely to make unsupported claims. This is borne out in our evaluations, which show that Opus 4.8 is around four times less likely than its predecessor to allow flaws in code it has written to pass unremarked.
- Anthropic
Improved
- Improved handling of oversized documents for greater reliability.
Fixed
- Fixed an issue impacting select users where images attached to a conversation weren't being read correctly.

New
- Connect your Autotask PSA to Hatz and put your ticket data to work. Search tickets, analyze trends, look up records, log time, create and update tickets, and make changes — all without leaving your Hatz workspace.
- Save generated files to Microsoft 365. Pick a destination in OneDrive or SharePoint right from Hatz and the file is copied using your Microsoft account.
- Admins can restrict direct downloads at the tenant or organization level, so users can still see and use files but can only export them to your sanctioned M365 destinations - or prevent downloading them at all.
- A new Usage tab gives client admins visibility into their organization's credit consumption, models, leaderboard, and activity — so you always know how your team is using Hatz without having to ask anyone.
- MSP Admins and Dashboard Users can now publish apps and workflows to a dedicated MSPs category in the Workshop community. Items published here are visible to MSP Admins and Dashboard Users across all MSPs and do not appear in the general community. Non-MSP users see no MSP category and cannot access MSP-published items.
Improved
- Email Agents now support attachments across all major file types — including documents, spreadsheets, images, audio, code files and plain text formats.
Fixed
- Fixed an issue where maximizing a workflow step output would cramp content against the edges of the overlay.
New
- Gemini 3.5 Flash is now available as a model option in Hatz AI. It supports fast, capable responses across chat, tool use, and image-based prompts, giving teams another strong option for everyday AI workflows. This new model boasts "Frontier intelligence, built for speed."
