Highlights​

This release brings a wave of new AI models — including Claude Opus 4.7, GPT-5.5, the Grok 4.20 family, and GPT Image 2 — adds custom prompts at both the account and organization level, and rolls out tenant-branded link previews for shared chats.

New features​

New AI models​

Several new models are now available across chat:

  • Claude Opus 4.7 — Anthropic's latest flagship model
  • GPT-5.5 — the newest model in the GPT-5 family
  • GPT Image 2 — improved image generation
  • Grok 4.20 and Grok 4.20 Imagine — xAI's latest release, including image generation

Account-level custom prompts​

You can now set your own system prompt overrides in account settings. Personal prompts apply to your conversations and stack cleanly with organization-level defaults.

Organization-level custom prompts​

Organization admins can now configure a shared system prompt for everyone in the org. Organization and account prompts follow a clear precedence so it's always obvious which one is active in a given conversation.

Link previews for shared chats now use your tenant's branding for the preview image. When someone shares a Devs.ai link in Slack, Teams, or any platform that unfurls links, the preview reflects your tenant's identity.

Improvements​

Smoother organization switching​

When you switch between marketplace organizations, sign-in is re-validated automatically so the new organization's permissions and settings take effect immediately, without manual sign-out.

Public API alignment​

The public API now mirrors the OpenAI Responses API specification more closely, making integrations and tooling more portable.

MCP improvements​

MCP tool calls now handle fallback JSON responses more gracefully when a provider returns non-standard output.

Security​

Stronger API key fingerprinting​

New API keys now use a stronger fingerprinting algorithm. Existing API keys continue to work — the change applies to keys created from this release forward.

Model retirements​

The legacy grok-beta model has been retired. Existing references continue to resolve to grok-3 automatically.

Bug fixes​

Various fixes across authentication, chat streaming, search, model selection, and reporting.
