Voice model company Cartesia launched Managed Agents on Oct 29, an end-to-end voice agent platform for enterprise phone calls that tunes its own speech-to-text and text-to-speech models together with the agent harness, and bundles telephony, knowledge bases, tool calls and outbound batches. Cartesia says it ranks #1 on Artificial Analysis's Speech Agent Arena with a 1115 Elo and scores 87.4% accuracy and 90.7% experience on ServiceNow's EVA-Bench (vendor-reported, with GPT-5.5 as the reasoning model). Launch pricing is 50% off at $0.03 per minute.

Google DeepMind announced Gemini 4 Carbon on Oct 28, calling it its strongest model, just two weeks after Gemini 4 Argon. The official blog says it ranks first on v5.0 of the Artificial Analysis Intelligence Index at 59 and leads three cybersecurity evaluations: 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation and 71.0% on CWE-bench for patching; it also gains 89 points to rank fourth on WebDev Arena at 1769. Access starts this week for a subset of cyber defenders in the Fairwind program, with developers, businesses and consumers to follow. Introductory pricing matches Argon at $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 afterwards.

Microsoft AI announced on Oct 27 that MAI-Image-2.6 and MAI-Image-2.6-Flash are generally available in Microsoft Foundry, with multi-reference editing from up to five images, Bing web grounding, output up to 1.5K and published per-token pricing. The same day its next image editing model, MAI-Image-2.7-Preview, reached #3 overall in Arena's Image Edit leaderboard at 1470 points, 45 points above 2.6; for now it is available only for editing in MAI Playground.

On Oct 22 Canva released Canva Craft, the first image-generation foundation model trained from scratch by its in-house lab, Canva Research. It works in two stages: a planning model writes out the composition (elements, spatial relationships, hierarchy and any text), then a rendering model produces the image at up to 2K across more than 30 aspect ratios. Training leaned heavily on millions of human-made templates from Canva's library, such as posters, social posts, slides and infographics. Canva says it debuted 4th overall on the crowdsourced DesignArena leaderboard and 1st in the People & Portraits and Landscapes & Nature categories. It is available now to all Canva users in Dream Lab and to developers through the Connect API as craft_v1_2k, with Canva MCP access coming soon.

On Oct 20, Krea said Krea 3, the image-editing model it released on Oct 15, has entered several third-party leaderboards. On Arena's Multi-Image Edit board, Krea 3 Ultra ranks #4 at 1435±11 (preliminary, 2,991 votes), behind three OpenAI models; it is #8 on single-image editing. On Artificial Analysis, Ultra scores 1151 Elo (#5) and Fast scores 1125 (#11). Krea 3 edits at native 2K, returns most edits in under 8 seconds and costs $0.06 per image.

On Oct 19 (UTC) fal released FLUX 3 Max, a video model built by fal Research with Black Forest Labs through post-training, reinforcement learning and inference optimization on top of the FLUX 3 foundation model. It handles text-to-video, image-to-video and keyframes, up to 20 seconds, at 720p or 1080p, with audio on by default. On Artificial Analysis's preliminary image-to-video arena it scores 1,139 Elo, level with Seedance 2.5 and within the confidence interval of leader MiniMax H3 (1,141), and fal says a 10-second clip takes about 12.45 seconds. A 75% launch discount runs until Nov 7, putting 720p at $0.0425 per second.

LMSYS officially announced a 14-day exclusive direct testing window for OpenAI flagship vision generative model GPT-Image-2.5 Sunburst in Direct Mode (active until Nov 2, 8 a.m. PT). Currently holding the undisputed #1 ranking across LMSYS Text-to-Image, Image Edit, and Multi-Image Edit arenas, the model can now be directly chosen from the dropdown menu before returning exclusively to anonymous Battle and Agent Mode.

MiniMax officially announced M3.1 Flash, its next-generation lightweight frontier model (previously dominating leaderboards as the secret model Space Bunny across 200T+ tokens). Featuring a native 1M context window, flat-rate API pricing of $0.15 / $0.60 per 1M input/output tokens ($0.015 cache reads), and 3x faster inference at 1/3 the cost of M3. It surged +106 points to 1588 on LMSYS Code Arena: WebDev (#12 among open models), with full weights set for open release on October 23.

Three new frameworks advance web and multimodal agent post-training: Salesforce AI Research's CLIFT (arXiv:2610.06829) certifies URL-conditional self-verification questions for dense RL rewards and judge-free Conformal Trajectory Selection (CTS), propelling Gemma-4 31B to a 74.6% SOTA on WebArena Infinity (beating Gemini 3 Flash at 70.1%) and lifting GPT-5.5 to 53.7% on VisualWebArena. Meanwhile, MMSearch-OPD (arXiv:2610.22240) boosts 9B multimodal deep search by +15.3 points to 60.2%, and Northeastern University's SCOPED-8B (arXiv:2610.22217) uses skill-decoupled on-policy expert distillation to reach 73.13% across 8 benchmarks—surpassing Qwen3-VL-32B (72.01%) and Claude Opus 4.6 (72.86%).

Robotics research typically separates world models (predicting scene transitions) from control policies (generating actions), fragmented by proprietary robot-specific kinematic formats. Sber AI researchers introduced GreenWAM, a foundational world model for robotics. GreenWAM unifies 20 robot embodiment families (from bimanual arms to dexterous humanoids) under a common joint coordinate space, co-training across visual, action-conditioned, and world-action objectives with specialized action-expert heads. GreenWAM achieves top-tier 3D trajectory and depth accuracy on WorldArena 1.0, establishes state-of-the-art policy benchmark scores on RoboTwin 2.0 and LIBERO-plus, and successfully drives real-world humanoid robots outperforming Cosmos 3 Edge and pi_0.5.

Arena released an agentic version of its Max router. Trained on 2.5M+ real Agent Arena sessions, it picks between Fable 5.1 (Max), Astra (Max) and Astra (Medium) per task based on complexity, task type and cost. In a live test it ranked #1 in Agent Arena with a +14.7% score at a $3.27 median cost per task — 0.3% better than the top public model, Fable 5.1 (Max), at 37.5% lower cost — and sent 67% of coding sessions to the cheaper Astra (Medium). It is free to try in Agent Mode for a limited time; API access is via a signup form.
