ElevenLabs Surpasses $500M ARR and Closes Series D with BlackRock and NVIDIA
ElevenLabsElevenLabs announced it has surpassed $500 million in annual recurring revenue and added strategic investors to its Series D round, now totaling over $550 million raised. New investors include BlackRock, Wellington Management, NVIDIA's NVentures, Santander, D.E. Shaw, Jamie Foxx, and Eva Longoria. Growth is driven by enterprise voice agent deployments across customer support, sales, and marketing — up from $350M ARR at end of 2025.
Suno in Talks to Raise $250M+ at $5 Billion Valuation, Doubling Prior Round
SunoAI music generation startup Suno is in talks to raise over $250 million at a valuation exceeding $5 billion, more than double its $2.45 billion post-money valuation from a November 2025 Series C. The round is expected to close within weeks. Suno currently has 2 million paid subscribers, $300 million ARR, and over 100 million total users, with growth driven by consumer adoption despite ongoing copyright litigation with Universal Music Group and Sony Music Entertainment.
DeepSeek Closes First External Funding Round at Up to $50B Valuation
DeepSeekDeepSeek is closing its first-ever external funding round at a valuation of $45–50 billion, led by affiliates of China's Big Fund III (China Integrated Circuit Industry Investment Fund), with Tencent and Alibaba reportedly also participating. The company aims to raise $3–4 billion to fund compute infrastructure and employee equity programs. Founder Liang Wenfeng, who controls nearly 90% of DeepSeek, previously resisted outside investment; the dramatic valuation reflects DeepSeek's strategic importance to China's AI self-sufficiency drive, as its models are optimized to run on Huawei Ascend chips.
Anthropic Signs $1.8 Billion Seven-Year Cloud Computing Deal with Akamai
AnthropicAnthropic signed a $1.8 billion, seven-year cloud computing agreement with Akamai Technologies — the largest deal in Akamai's history. The announcement coincided with CEO Dario Amodei disclosing 80-fold annualized ARR growth in Q1 2026, with revenue reaching approximately $30 billion annualized. The deal supplements the SpaceX Colossus arrangement announced earlier in the week, as Anthropic expands compute capacity to meet surging Claude Code enterprise adoption.
ByteDance Launches Doubao-Seed-2.0-lite: First Omni-Modal Model in Seed Series
ByteDanceByteDance's Volcano Engine announced Doubao-Seed-2.0-lite, the first full-modal understanding model in the Doubao Seed family, natively processing video, image, audio, and text within a single model. The model supports transcription in 19 languages, translation across 14 languages, and introduces GUI interaction capabilities enabling it to recognize and operate interface elements (clicking, dragging, typing). A more efficient Doubao-Seed-2.0-mini variant was also released simultaneously for cost-effective enterprise deployment.
Zyphra Releases ZAYA1-8B: Open Reasoning MoE Model Trained on AMD Hardware
ZyphraZyphra released ZAYA1-8B, an Apache 2.0-licensed mixture-of-experts reasoning model with under 1 billion active parameters that matches or exceeds larger open-weight models on AIME, LiveCodeBench, and GPQA-Diamond. The model was pretrained on 1,024 AMD Instinct MI300X GPUs and introduces Markovian RSA, a new test-time compute method enabling unbounded reasoning at constant memory cost. Weights are on HuggingFace and a serverless endpoint is live on Zyphra Cloud.
OpenAI Discloses Accidental Chain-of-Thought Grading in RL Training Across Six Models
OpenAIOpenAI disclosed that six released models — GPT-5.4 Thinking, GPT-5.1–5.4 Instant, and GPT-5.3–5.4 mini — were inadvertently exposed to chain-of-thought grading during RL training, a practice their policy prohibits because it creates incentives for models to produce misleading reasoning traces. An automated detection system based on regex matching identified three specific accidental CoT-grading instances; reward pathways were fixed and ablations found no clear reduction in CoT monitorability, though unmeasured effects cannot be ruled out. Redwood Research provided an independent external review.
OpenSearch-VL: Open Recipe for Training Frontier Multimodal Search Agents
Tencent HunyuanOpenSearch-VL provides a fully open framework for training multimodal deep-search agents that operate as closed-loop systems: they inspect images, crop regions of interest, issue web and image searches, visit retrieved pages, and answer grounded in gathered evidence. The paper introduces a multi-turn fatal-aware GRPO training algorithm that handles cascading tool failures, achieves over 10-point average improvements across seven benchmarks, and releases all data, code, and model checkpoints.
ARIS: Autonomous ML Research via Adversarial Multi-Agent Collaboration
Shanghai Jiao Tong UniversityARIS is an open-source research harness for autonomous ML research addressing 'plausible unsupported success' — where long-running agent claims lack proper evidential grounding. The system pairs an executor model with a reviewer from a different model family (adversarial cross-model collaboration) and adds a three-stage assurance layer: integrity check, results-to-claims mapping, and manuscript audit against raw evidence. 65+ reusable research skills cover the full experiment lifecycle.

Direct Corpus Interaction: Rethinking Retrieval for Agentic Search
TIGER-LabThis paper challenges the assumption that vector-similarity retrieval is optimal for language agents. Direct Corpus Interaction (DCI) lets agents use general-purpose tools such as grep and file reads to search raw corpora, enabling exact lexical constraints, multi-step hypothesis refinement, and local context verification. DCI substantially outperforms strong sparse, dense, and reranking baselines on BRIGHT and BEIR benchmarks without requiring offline indexing or specialized retrieval APIs.
Cola DLM: Continuous Latent Diffusion Language Model with Competitive Scaling
Cola DLM proposes an alternative to autoregressive text generation through hierarchical information decomposition: a VAE maps text to continuous latents, a diffusion transformer models semantic patterns, and a decoder generates text conditionally. This separation of global semantic organization from local textual realization enables non-autoregressive generation while demonstrating scaling efficiency comparable to conventional autoregressive models at approximately 2B parameters.
Codex CLI 0.130.0: Remote-Control Command for Headless App-Servers
OpenAICodex CLI 0.130.0 ships the new `codex remote-control` entry point for headless, remotely controllable app-servers, letting users drive Codex sessions programmatically from another machine. The release also adds support for AWS console-login credentials via Bedrock, plugin hook exposure in details views, and thread pagination for app-server clients.
Claude Code v2.1.136: MCP Reliability Fixes and hard_deny Auto Mode
AnthropicClaude Code v2.1.136 adds `settings.autoMode.hard_deny` for unconditional auto-mode classifier rules and `CLAUDE_CODE_ENABLE_FEEDBACK_SURVEY_FOR_OTEL` for enterprise OpenTelemetry users. The release fixes MCP servers disappearing from `.mcp.json`, plugins, and claude.ai connectors after `/clear`; resolves OAuth refresh token loss during concurrent MCP server refreshes; and corrects a 400 API error when extended thinking emitted a redacted thinking block after a tool call.
Windsurf 2.2.17: Devin Review and Quick Review Open to All Subscribers
WindsurfWindsurf 2.2.17 opens Devin Review and Quick Review to all Windsurf subscribers, bringing AI-driven code review into the editor without an additional plan. The release also improves Agent Command Center session management with list display, sorting/filtering, and performance fixes for session loading and switching, and increases MCP server and Devin Local agent stability.
llama.cpp b9085: MiMo-V2.5 Flash Attention and Vertex AI Server Support
llama.cpp builds released May 8–9 include two notable features: b9077 adds a Vertex AI-compatible server API endpoint configured via `AIP_*` environment variables for drop-in cloud integration, and b9085 adds flash attention MMA/tiles support for MiMo-V2.5 models with GQA handling optimizations. Additional builds add a Hexagon HTP kernel for Gated Delta Net recurrence and Gemma4_26B_A4B_NVFP4 GGUF conversion support.
Zed 1.1.5: DeepSeek V4-Pro, OpenCode Go, and Agentic Panel Layout
Zed IndustriesZed 1.1.5 adds DeepSeek V4-Pro/Flash and OpenCode Go as model/provider options, improves edit tool performance for streaming tool calls, and introduces a panel layout switcher with a dedicated 'agentic' mode alongside the classic editor layout. The release also adds LSP code lens support, Helix navigation motions, a git graph view, and GFM alert callouts in markdown preview.
