What's New

GPT-6.1 Sol (gpt-6.1-sol) is now available in the model picker and the AI workflow designer. OpenAI positions it close to GPT-6 Astra on complex coding, computer use, and professional work, at a lower cost, with a 1.05M token context window. Select it under the OpenAI provider anywhere a model can be chosen.

Three new Claude models are available in the model picker and the AI workflow designer:

• Claude Opus 5.5 (claude-opus-5-5) — succeeds Claude Opus 5 at a lower price, with a 1M token context window.
• Claude Sonnet 5.5 (claude-sonnet-5-5) — succeeds Claude Sonnet 5 at the same price, with a 1M token context window.
• Claude Haiku 5.5 (claude-haiku-5-5) — the fastest and most cost-effective Claude model, now with a 1M token context window.

Select them under the Anthropic provider anywhere a model can be chosen. Claude Sonnet 5.5 is now the default model when you choose Anthropic.

Google has deprecated two Gemini models and now routes their API requests to newer ones:

• Gemini 3.7 Flash (gemini-3.7-flash) → Gemini 3.8 Flash (gemini-3.8-flash)
• Gemini 3.5 Flash (gemini-3.5-flash) → Gemini 3.6 Flash (gemini-3.6-flash)

Both are removed from the model picker. Existing workflows keep running and now call the replacement model directly. Agent nodes that still use a deprecated model show a warning in the editor with a one-click Switch button. Gemini 3.8 Flash uses more tokens than 3.7 Flash, so expect higher usage on those nodes.

Gemini 3.8 Flash is now the default model when you choose Google Gemini. Gemini 3.5 Flash-Lite is not affected.

We've shipped a set of security improvements across the platform.

Shell Runner and Script Runner are now off by default. An organization Admin can enable code execution in Settings → General. If an existing workflow uses either node, an Admin needs to enable it before the workflow will run again.

GPT-6 Astra (gpt-6-astra) is now available in the model picker and the AI workflow designer — OpenAI's frontier GPT-6 model, a step-change over the GPT-5.6 family (Sol/Terra/Luna) on deep reasoning, agentic tool use, and long-horizon work, with a 2M token context window. Select it under the OpenAI provider anywhere a model can be chosen. GPT-5.6 Terra remains the recommended production default for OpenAI.

Zhipu AI's latest GLM release is now available via the Ollama Cloud provider (glm-5.3). It supersedes GLM-5 with major gains in coding and agentic-task performance from scaled post-training, and a 1M token context window.

Four new models landed in the model picker:

• Claude Fable 5.1 (claude-fable-5-1) — Anthropic's most capable widely-released model, succeeding Claude Fable 5 in the same tier and at the same price.
• Gemini 3.8 Flash (gemini-3.8-flash) — Google's most intelligent workhorse yet, with major gains on software engineering and agentic tasks over 3.7 Flash.
• Gemini 3.7 Flash (gemini-3.7-flash) — the prior-generation Flash release, still fully supported for lower-token-usage workloads.
• Grok 4.6 (grok-4.6) — xAI's new flagship, succeeding Grok 4.5 with configurable reasoning effort up to xhigh.

Claude Opus 5 (claude-opus-5) is now available — the new flagship of the Opus tier, a step-change over Opus 4.8 on deep reasoning, agentic coding, and long-horizon work, at the same $5/$25-per-million-token pricing as its predecessor. Now the recommended Opus-tier pick on the platform.

Added Claude Fable 5, Claude Opus 4.8, and Claude Sonnet 5 (Anthropic); GPT-5.6 Sol/Terra/Luna (OpenAI); Gemini 3.6 Flash and Gemini 3.5 Flash-Lite (Google); Grok 4.5 (xAI); Kimi K3/K2.6 (Ollama Cloud); and Llama 4, Qwen 3.6, Mistral Small 4 (HuggingFace). Also refreshed each provider's recommended default model and fixed several default-model IDs that no longer matched any model in the catalog.

Organizations can now export a full, tamper-evident audit trail of account activity from Settings, with a dedicated log viewer and CSV export — built for compliance reviews.
