New AI infra unicorns: Exa, Modal, Turbopuffer
A Latent Space AINews roundup (published 2026-05-22) highlights major AI infrastructure and compute developments: Modal closed a $355M Series C at a reported $4.65B valuation, Exa raised $250M at a $2.2B Series C, and Turbopuffer reached ~$100M ARR while remaining profitable after raising under $1M. The newsletter also summarizes technical research (RAEv2, Gated DeltaNet-2), product and agent tooling updates (OpenAI Codex product features, Gemini agent advances), developer infra improvements (Weaviate MCP server, LangChain sandbox proxy, vLLM elastic MoE resizing), and broader market signals including Hark’s $700M raise and compute-capacity taxonomies. The piece frames a clear capital and engineering flow toward AI infra, agent-native compute, and tooling that enable scaled multimodal and agentic workflows.
Major funding rounds and revenue milestones for core AI infrastructure firms, plus advances in agent-native compute and developer tooling, materially affect future model hosting, compute supply, developer workflows and costs that underpin AI-enabled products across industries.

AI infra decacorns: Fireworks, Baseten, OpenRouter $113M
Latent Space's AINews roundup (published 2026-05-27) highlights rapid AI infrastructure fundraising and technical trends. The newsletter reports Fireworks and Baseten moving toward decacorn-scale financings (Fireworks cited at ~$15B, Baseten at ~$11B, both described as in-talks/raising). OpenRouter announced a $113M raise and strong production token growth (weekly volume rising from 5T to 25T tokens in six months); coverage notes press discrepancies about whether that round is Series B or Series C. The issue also surveys agent and harness engineering as the key differentiator for coding/ research agents, benchmarks (DeepSWE, Qwen3.7) aligning with developer experience, memory and “sleep”-style consolidation research, optimizer and sparse-attention advances, datacenter power/inference supply concerns, and serving/observability improvements (vLLM Rust frontend, W&B MCP, Cloudflare startups credits). The piece frames routing and multi-model infra as durable platform layers as AI moves from experimentation to production.
AI Market Shifts: Funding, Model Releases, Agent Era
This newsletter summarizes a week of industry-moving AI developments that together signal a shift from demo-driven product cycles to infrastructure-driven competition. Major items include OpenAI closing a $122 billion funding round at an $852 billion valuation; Microsoft releasing three new models (MAI-Transcribe-1, MAI-Voice-1, MAI-Image-2); Google DeepMind expanding Gemma 4; and Z.ai open-sourcing GLM-5V Turbo. The piece argues the market is reorganizing around who can finance, compress, deploy and operationalize intelligence at scale, with speech/voice/image modalities and multimodal/agent capabilities becoming core platform differentiators. The newsletter also summarizes multiple research papers and additional funding, M&A and startup news (Arcee AI, Anthropic’s acquisition of Coefficient Bio, ScaleOps, Rebellions, Mistral, Sarvam AI, and others) that underscore growing capital flows, infrastructure builds, and a move toward agentic, multimodal AI systems.
AI Labs Race to Own Developer Tools and Agent Runtimes
Latent Space's AINews roundup (3/18–3/19/2026) reports consolidation and rapid product activity in developer-facing AI: OpenAI acquired Astral (the team behind uv, ruff, ty) into its Codex efforts; Cursor launched Composer 2, a frontier-class coding model claiming strong price/performance; Anthropic expanded Claude Code with messaging channels and persistent developer workflows; and LangChain introduced LangSmith Fleet for enterprise agent fleets. The dispatch highlights a shift from single agents to managed fleets, multi-agent runtimes, and permissioned agent control planes, while security, identity-based authorization, and observability were emphasized across launches. It also summarizes model releases and benchmarks (MiniMax M2.7, Qwen 3.5 Max Preview), advances in OCR/document parsing (Chandra OCR 2, LlamaIndex LiteParse), and infrastructure research trends like continued pretraining before RL and late-interaction retrieval gains.
