Artificial Analysis (@ArtificialAnlys) updated its Speech to Speech Index: Google Gemini 3.8 Live Extended Thinking (High) debuts at #1 with 82.6, ahead of GPT-Live-1 (Astra medium) at 81.5 and Grok Voice Think Fast 2.0 High at 81.3; standard Gemini 3.8 Live lands #5 at 76.0. The same drop covers Speech Agent Arena, Tau Voice (Extended Thinking leads at 68.6%), Big Bench Audio, time-to-first-audio, and input-audio cost ($0.84/hr standard, $3.50/hr Extended Thinking).

Arena updated the Image-to-WebDev leaderboard: GPT-6 Astra (Max) leads at 1733 points, 129 above GPT-5.6 Sol (xHigh); Claude Fable 5.1 (Max) is second at 1710. The board compares newly evaluated model releases on image-to-webdev delivery.

Artificial Analysis (@ArtificialAnlys) published its Speech to Speech Index: OpenAI GPT-Live-1 with Astra (medium) as the delegated backend debuts at #1 with 81.5, while Sol (low) scores 80.1 at #3, with Grok Voice Think Fast 2.0 High between them at 81.3. GPT-Live-1 is a full-duplex speech model that can delegate reasoning and tool use to a backend text model mid-conversation. The same drop covers Speech Agent Arena, Tau Voice, Big Bench Audio, plus cost and time-to-first-audio.

Arena.ai (@arena) reports Agent Arena results: DeepSeek-V4.1-Flash (Max) posts about +4.87% net improvement at roughly $0.07 median task cost — lowest among the top-3 open models — retaining ~98% of Hy4 preview’s net gain at ~73% lower cost and ~76% of Kimi K3 (Max) performance at ~92% lower cost.

LMArena reports Muse Spark 1.3 (Max) at #13 on Agent Arena with +4.2% net improvement across 8.7K+ real agentic sessions — a 17-rank climb from Muse Spark 1.2 (xHigh) at #30. Code, Work, and Chat all improved, with Code moving to #15 (+4.3%).

Arena.ai says Anthropic Claude Fable 5.1 (Max) is #1 on Agent Arena across 6.7k+ real-world long-horizon agentic sessions with +15.8% net improvement, redrawing the price-performance frontier at a $4.14 median cost/task. Implicit praise-vs-complaint leads by +42.5%, confirmed success +22.4%, bash recovery +13.1%, and no tool hallucinations; GPT-6 Astra traces are still coming in.

Arena.ai (@arena) says Meta Muse Spark 1.3 is now in the Arena: Agent Arena measures long-horizon agentic tasks with web search, filesystem, and terminal tools via causal tracing vs the average model; it is also in Code Arena WebDev/Text/Vision/Document. Voting is open and scores are coming soon.

Arena.ai (@arena) says Google DeepMind’s Gemini 3.8 Flash (High) put Gemini on the Agent Arena Pareto frontier for the first time: $0.75/$3.75 per MTok, ~$0.22 median cost per Agent Arena task with +5.94% net gain—on par with Grok 4.5 and GLM 5.2 (Max) at roughly 44–50% lower price.

Cursor (@cursor_ai) announces Gemini 3.8 Flash is now available in Cursor. Paired with Google DeepMind’s same-day agent/cyber narrative and clear Agent Arena gains, developers can use the faster, stronger Flash-tier model inside their familiar AI coding IDE.

LMArena (@arena) breaks down Gemini 3.8 Flash (High) vs 3.7 Flash (High) on Agent Arena: net improvement jumps from +0.84% (#32) to +5.94% (#14). Agent Arena scores relative gains on real long-horizon tasks with web, filesystem, and terminal tools. Among five signals, Praise vs Complaint improves most (+14.78% vs -1.60%); Confirmed Success and Bash Recovery also rise, while Steerability remains a relative weakness but better than 3.7.

LMArena (@arena) says Gemini 3.8 Flash (High) is live across Agent Arena, Text Arena, and Code Arena WebDev. It ranks #14 in Agent Arena (+5.94% net, up from 3.7 Flash at #32), #7 in Text Arena (1494 pts) with Coding category jumping #22→#7, and #18 in Code Arena WebDev (1567 pts).

LMArena (@arena) said Anthropic’s Claude Fable 5.1 is now live for Arena voting, with scores coming soon. Agent Arena measures long-horizon real-world agent tasks where models can use web search, filesystem, and terminal tools; Fable 5.1 is also in Code Arena WebDev, Text, Vision, and Document.
