Models & Products

• Beam 1.0 — instruction-tuned model, released with multiple numerical formats. (source)
• Mirror CLI — terminal harness with resumable conversations, tool approvals, MCP connections and parallel agents in separate worktrees. (source)

Recent Activity

• 2026-10-16: released Beam weights under Apache 2.0, alongside deployment and customization integrations. (source)

Strategic Position

The release emphasizes developer control across self-hosting, managed endpoints, agent runtimes and post-training. This is Reflection's stated strategy; its selected demos do not establish general production reliability. (source)
