Big-AGI 2.1.0 - Weights Dust

Six new vendors.

Cerebras, NVIDIA NIM, Sakana AI, Cohere, Modular and Nous Research, each with a setup guide. Plus model updates across Anthropic, OpenAI, Gemini, xAI, Moonshot and Z.ai, a multi-vendor transcription framework, explicit reasoning-effort and mode controls, and code sandboxes that persist across turns. 628 commits since 2.0.5.

New Vendors

• Cerebras first-class vendor support, with live catalog and CSF (#1146) - setup
• NVIDIA NIM with a curated catalog and sync tooling - setup
• Sakana AI on the Responses API: Fugu Cyber, Fugu Ultra 1.1, Namazu (#1142) - setup
• Cohere model family, including Aya - setup
• Modular with MiniMax M3, Kimi K2.7 Code and Gemma 4 - setup
• Nous Research Hermes models and the Portal subscription gateway, and EmpirioLabs (#1129), both via custom endpoints

Models

• Anthropic Opus 5, Sonnet 5, Opus 4.8, plus Fable 5 and Mythos 5
• OpenAI GPT-5.6 Sol/Terra/Luna, with Reasoning Mode (#1158) and Max effort (#1159)
• Google Gemini 3.5 / 3.6 / 3.7 Flash, Nano Banana 2 Lite, Robotics-ER 2, and 3.7 video understanding
• xAI Grok 4.5, 4.6 and Grok Build 0.1, with none/x-high efforts (#1104)
• Moonshot Kimi K3, and Kimi Code subscription keys (#1161)
• Z.ai GLM-5.2 / 5.3, Alibaba Qwen 3.7 Flash, DeepSeek V4 Flash and Pro, MiniMax M3

Transcription (New)

• Multi-vendor speech-to-text framework, with its own Settings section - voice docs
• Deepgram diarization, dictionaries, topic and sentiment detection, word-level spans
• OpenAI gpt-transcribe with keyword and language hints, and diarization
• Per-engine instances and profiles, sharing the config layout with Speech and Draw

Sandboxes & Containers

• Anthropic: standalone Code Sandbox toggle, container re-attached across dynamic-web turns (#1087)
• OpenAI: container files as hosted resources - download, embed, sandbox-link interception; code execution downgrades to function calls when a container expires
• Gemini: Omni, video output, Antigravity agent events, and the Interactions protocol rewrite with usage metrics (#1143)

Reasoning & Caching

• OpenAI Responses: reasoning phase (commentary vs final) and client-controlled policy, defaulting to all-turns on GPT-5.4+
• OpenRouter: reasoning on/off/default (#1138), Anthropic-style prompt caching via ephemeral breakpoints, session affinity
• Anthropic: reasoning token accounting, x-high auto-probing, cache breakpoints capped at the API limit (#623)
• Vertex AI redirect links resolved automatically or on demand (#1114)

Reliability

• Multi-tab rewritten on Web Locks; demote-by-wipe replaces the old heuristic (#802)
• Warning that chats live in the browser and are lost on cache clear (#672)
• Auto-reload once on stale-deploy chunk load errors, and denoised error reporting
• Browser support floor enforced in lint, Intl.Segmenter fallback, tiktoken preload failures tolerated

Also New

• Draw: OpenRouter image generation on the dedicated Image API, engine-instance settings
• Settings redesign, Diagnostics section, model assignments with per-domain Auto picks
• Token stats during generation, not just at the end (#1125)
• Markdown preview for .md fenced code (#1126), rendered ```svg blocks, Live-SVG
• Mobile wake lock, model-select search that keeps focus, attachment rename
• Removed: Helicone (maintenance mode), OpenPipe (discontinued), react-player

Developers

• AIX Protocol Lab: protocol microscope and differential tester for the decode layer, alongside the AI Inspector
• Anthropic and Claude Code protocol eviscerators, standalone storage and diagnostics tools
• Per-vendor model-defs manifest with selective boot refresh: model updates no longer need an AIX roll
• Tests wired into CI, type-checking extended over tools/

New Contributors

• @mahirhir made their first contribution in #1145
• @Robinnnnn made their first contribution in #1156
