Meta’s Muse Spark Open lands in Amazon SageMaker JumpStart
AWS has added Meta’s Muse Spark Open to SageMaker JumpStart in BF16 and NVFP4 variants. The open-weight coding model has 816 billion total parameters, activates 42 billion per token and supports a one-million-token context across text and multimodal inputs. Customers can deploy controlled endpoints, but multi-GPU cost, licensing and tool permissions require careful evaluation.
Cohere finds strong leads can cut multi-agent coding costs
Cohere research finds that coding-agent teams can outperform solo agents, but indiscriminate delegation costs three to seven times more. On ProgramBench, a Sol lead with 16 inexpensive Luna planning workers reached 61.8 per cent reward at US$155—close to an all-Sol team’s 63.2 per cent at US$510.
Grok Build adds project memory written quietly between coding sessions
SpaceXAI has added persistent memory to Grok Build, storing project conventions, decisions and durable facts as Markdown notes for later sessions. The 16 September release introduces /memory for inspection and /dream for organising notes. The design could reduce repeated setup, but teams should verify what is retained, exclude secrets and keep repository documentation authoritative.
Mintlify lets coding agents create documentation accounts from the CLI
Mintlify has added a mint signup command that lets coding agents create an account, initialise a documentation project and deploy from the terminal. The release is designed to remove the browser-based sign-up step for agent-led documentation workflows while retaining email verification and locally stored authentication.
DataRobot Adds Model Choice to OpenCode Coding Agent
DataRobot has released an OpenCode integration that lets developers use closed, open-weight or bring-your-own models through its governed LLM Gateway. The coding agent is available from the DataRobot CLI and browser interface, with DataRobot skills and Agent Assist included.
