New deltas

Drafted from reviewed evidence and published without a site rebuild. They join the catalog below at the next release.

  1. NewBuildability B1

    A public index makes decision models comparable

    Builders had no cited public composite index for comparing models that select among fixed options. -> Builders can consult a documented composite benchmark to compare decision models across four evaluation areas.

  2. NewBuildability B2

    Decision models become selectable across hosted AI gateways

    Builders could use hosted gateways for model calls, but these items do not establish access there to the newly reported decision-model options and Decisions API. -> Builders can access decision-oriented models or APIs through multiple hosted AI gateway offerings.

  3. NewBuildability B3

    Microsoft’s MAI audio models become available through AI Gateway

    Builders could not use these newly launched MAI audio models for real-time transcription or voice generation. -> Builders can access the MAI audio models, including through Vercel AI Gateway, for audio applications.

  4. NewBuildability B3

    Agents can define document extraction schemas via natural language conversation

    Agents needed manually authored JSON schemas or code to specify how to parse and extract fields from documents. -> Agents can interactively create and run extraction pipelines by describing the desired fields in natural language, enabling on‑the‑fly schema generation.

01

Runtime memory becomes inspectable behavior

Operators can increasingly inspect what an agent stored, recalled, merged, and spent instead of treating memory as hidden prompt state.

BeforeMemory is hidden inside session context; operators infer its effects from an answer or failure.

Enabling changeMemory operations and long-running trajectories are emitted into observable runtime surfaces.

AfterAn operator can review memory actions, cost, confidence, and their role in a run.

Debugging and governance shift from reconstructing hidden context to inspecting evidence, while privacy and retention risks become visible obligations.

02

Agent-first API makes retries deterministic

Explicit fields, precise errors, request metadata, and raw facts turn an agent retry from guessing into near-deterministic repair.

BeforeAgent calls a human-friendly SDK and receives an opaque failure.

Enabling changeAPI returns command, exit code, stderr, allowed values, request id, timeout, and raw metadata.

AfterAgent can correct the next tool call from explicit machine-readable facts.

The human spends less time reading logs for the agent and explaining what exactly broke.

03

Attacker-first agents turn vuln triage into repair candidates

A security agent can start from attacker-first exploit-path search and prepare a production-code fix instead of following an abstract checklist.

BeforeSecurity review identifies a vulnerability and hands remediation back to humans.

Enabling changeVulnHunter-style agent reasons from attacker behavior to vulnerable code and repair candidates.

AfterThe workflow can move from exploit-oriented analysis to proposed code change faster.

Security teams get a more actionable review artifact, but still need human approval before code changes.

Shared context lets AI clients stop starting from zero

A separate context layer lets multiple AI clients read shared project context without a human manually copying memory.

BeforeEach AI client learns the project separately and loses context when the user switches tools.

Enabling changeA shared MCP-compatible context layer exposes structured memory outside one client.

AfterDifferent agents can reuse the same governed project context.

The user spends less time carrying decisions, architecture notes, and preferences between Claude, Codex, Cursor, and other clients.
