## Releases

### [How We Optimized Browser Use for Deep Agents](https://mediarelease.co/us/mr02670-langchain-optimized-browser-use-deep-agents-stagehand-04112026.html)

Issued by: LangChain · Original source: https://www.langchain.com/blog/how-we-optimized-browser-use-for-deep-agents

LangChain describes how it chose and tuned browser-use tools for Managed Deep Agents after comparing seven toolsets and selecting Stagehand from Browserbase. The team used LangSmith traces and evals on WebVoyager, HardBench and WebTailBench to cut wasted steps and tokens. The post argues that tool design has a large effect on agent cost and trajectory for long-running browser tasks.

Lambda has added identity and access management with role-based access control to Lambda Cloud. Admins can assign fine-grained roles to users, groups and service identities at account or workspace scope, so automation no longer needs a personal API key with full access. Predefined roles include Account Admin, IAM Admin, Billing Admin, Workspace Owner, Workspace Member and Instance Reader, with audit logs retained for six months.

### [ElevenAgents integrates natively with leading contact center platforms to deliver enterprise-ready agents](https://mediarelease.co/us/mr02665-elevenlabs-elevenagents-nice-genesys-amazon-connect-five9-04112026.html)

ElevenLabs says ElevenAgents now integrates natively with NiCE CXone, Genesys Cloud, Amazon Connect and Five9, with SIP available for other platforms. Enterprises can add voice agents inside existing call flows, routing, compliance recording and CRM systems without replacing their contact center stack. Agents can verify callers, complete routine tasks, log outcomes and hand off to a person with full context when needed.

### [Embed 5 and Rerank 5 now on OpenRouter](https://mediarelease.co/us/mr02663-cohere-embed-5-rerank-5-openrouter-rag-04112026.html)

Issued by: Cohere · Original source: https://cohere.com/blog/embed-rerank-5-openrouter

Cohere’s Embed 5 and Rerank 5 retrieval models are now available on OpenRouter through a single API with unified billing. Cohere says the models are its strongest yet for enterprise documents and complex retrieval, and that Embed 5 Pro and Fast share one embedding space so teams can index for quality and query for latency. Rerank 5 scores are calibrated across queries and domains so one relevance threshold can filter weak context before generation.

Fireworks AI says Moonshot AI’s Kimi K3.1 Pro is available on its platform at launch, with serverless pay-per-token pricing and dedicated deployments. In Fireworks’ Specialized Intelligence Index evaluations, K3.1 Pro was the fastest model on Legacy Bench and CorporateBench and second-fastest on ORCA. Moonshot post-trained K3.1 Pro from K3 and replaced full-attention layers with sparse attention for more efficient long-context serving.
