# Changelog

> Product updates and new features across OpenServ.

<Update label="July 31, 2026" tags={["SERV Reasoning"]}>
  ## Updates

  * **Model selection guidance, generalized.** Day One now recommends starting with the smallest, least expensive model that plausibly fits your task — rather than naming specific tiers — and moving up only when evaluations show a meaningful quality gap. [Open Day One →](/serv-reasoning/day-one)
  * **Model catalog refresh.** Claude Opus 4.8 Fast has been removed from the catalog. Remaining Opus 4.x models continue to be available. [Browse models →](/serv-reasoning/models)
</Update>

<Update label="July 24, 2026" tags={["SERV Reasoning"]}>
  ## New features

  * **`serv_disable_content_filter`.** SERV runs a system-prompt content filter on every request by default; declare this tool by name to turn it off for requests where your application intends the model to quote or explain its own instructions. [See usage →](/serv-reasoning/tools#serv_disable_content_filter)

  ## Updates

  * **New models available through SERV.** Added Claude Opus 4.7, Opus 4.8, Opus 4.8 Fast, Sonnet 5, and Fable 5; GPT-5.6 Luna, Sol, and Terra; Gemini 2.5 Flash, 2.5 Flash Lite, 3 Flash Preview, 3.1 Pro Preview, and 3.5 Flash; Grok 4.5; Qwen 3.7 Max and 3.7 Plus; Kimi K2.6 and K2.7 Code; Nemotron 3 Ultra and OpenRouter Fusion; and Z.ai GLM 5.2. Retired the OpenAI o3, o3 Mini, o3 Pro, and o4 Mini entries. [Browse the full catalog →](/serv-reasoning/models)
  * **Auto-updating model catalog.** The [models page](/serv-reasoning/models) is now generated from the live SERV API, so pricing and context windows stay current without a docs release. Several existing models (Claude Opus 4.6, Sonnet 4.6, Grok 4.3/4.20, Qwen3.6 Flash, DeepSeek V4, GPT-5.4 Nano) now show corrected context windows.
</Update>

<Update label="July 3, 2026" tags={["SERV Reasoning"]}>
  ## New features

  * **SERV Tools.** Enable server-side features by declaring specially named tools in any request — no SERV-specific API required. SERV detects tools prefixed with `serv_`, activates the feature, and strips the tool before the model runs. Works identically across the OpenAI SDK, Anthropic SDK, Vercel AI SDK, and raw HTTP. [Read the reference →](/serv-reasoning/tools)
  * **`serv_prompt_guard`.** Opt-in protection against prompt-injection attacks that try to leak or override your system prompt. Declare the tool by name to enable it — no parameters needed. [See usage →](/serv-reasoning/tools#serv_prompt_guard)
  * **`serv_shadow_agent`.** Runs a validate-and-iterate loop over the model's output to raise accuracy on hard tasks. Configure `hint` and `max_iterations` through schema defaults. [See usage →](/serv-reasoning/tools#serv_shadow_agent)
</Update>

<Update label="June 26, 2026" tags={["Build", "Launch", "Run", "SERV Reasoning"]}>
  ## New features

  * **Build, Launch, Run.** The full OpenServ platform is now organized around three product surfaces: [Build](/build/index) for shipping agents and apps, [Launch](/launch/index) for token launches without presales or VCs, and [Run](/run/index) for the AI Cofounder Suite that handles post-launch operations.
  * **OpenClaw.** A new OS-level gateway for AI agents across WhatsApp, Telegram, Discord, iMessage, and more — send a message, get an agent response. Includes a quickstart, ERC-8004 identity, x402 marketplace agents, and Telegram and Twitter integrations. [Start with OpenClaw →](/vibecode/openclaw/index)
  * **OpenServ Skills + ClawHub.** Official OpenServ skills (`openserv-agent-sdk`, `openserv-client`, `openserv-multi-agent-workflows`, `openserv-ideaboard-api`, `openserv-launch`) are now installable into any coding agent or IDE, with [ClawHub](https://clawhub.ai) as the public registry. [Browse skills →](/vibecode/skills)
  * **No-code path.** A guided no-code experience for building with Workflows, Agents, and Connect — no SDK required. [Open the no-code quickstart →](/no-code/index)

  ## Updates

  * **SDK Integration reference.** New page covering the three SERV endpoints (`/v1/chat/completions`, `/v1/responses`, `/v1/messages`) with side-by-side OpenAI and Anthropic SDK examples and a full parameter map. [Open the reference →](/serv-reasoning/sdk-integration)
  * **SDK Migration guide.** Step-by-step migration paths for Python (`openai`, `anthropic`), the Vercel AI SDK, LangChain, LlamaIndex, Mastra, AutoGen, CrewAI, Instructor, LiteLLM, and raw `fetch`. [Read the guide →](/serv-reasoning/sdk-migration)
  * **Day One with SERV.** Production-ready defaults — which model size to start with, when to upgrade, and which tasks to delegate to the model vs. your application. [Open Day One →](/serv-reasoning/day-one)
</Update>

<Update label="June 12, 2026" tags={["SERV Reasoning"]}>
  ## Updates

  * **Expanded model catalog.** Added GPT-5.5, GPT-5.4, GPT-5.4 Mini, GPT-5.4 Nano, Claude Opus 4.6, Claude Sonnet 4.6, Claude Haiku 4.5, Gemini Flash Latest, Gemini Pro Latest, Gemma 4, Grok 4.3 and 4.20, Qwen 3.6, and DeepSeek v4 — all available through the same SERV endpoint with pricing and context windows on a single page. [Browse models →](/serv-reasoning/models)
  * **Same-model performance comparison.** New benchmark visual on the [SERV Reasoning overview](/serv-reasoning/index) shows accuracy vs. inference cost for each model with and without SERV Reasoning on a DeFi trade-decision benchmark.
  * **Quickstart, refined.** First-request examples now cover the OpenAI SDK, Anthropic SDK, and raw HTTP against `/v1/chat/completions`, `/v1/responses`, and `/v1/messages`, with the SERV-specific behaviors called out up front. [Open the quickstart →](/serv-reasoning/introduction)
  * **`reasoning_effort` values clarified.** Accepted values are `none`, `low`, `medium`, and `high`. If you were passing `minimal`, switch to `low`.
</Update>

<Update label="May 29, 2026" tags={["SERV Reasoning"]}>
  ## New features

  * **Playground.** Try SERV Reasoning side by side with any base model — same prompt, two outputs, real token, cost, and latency numbers. No SDK setup required. [Open the Playground →](/serv-reasoning/playground)
  * **OpenAI- and Anthropic-compatible inference API.** Point your existing OpenAI or Anthropic SDK at the SERV endpoint and keep your prompts, tool definitions, and application logic unchanged. See the [Chat Completions](/serv-reasoning/api/chat-completions), [Responses](/serv-reasoning/api/responses), and [Messages](/serv-reasoning/api/messages) references, plus the [compatibility notes](/serv-reasoning/api/compatibility).
  * **BRAID research framework.** Published the research behind SERV Reasoning — bounded, machine-readable reasoning graphs that replace free-form chain-of-thought. [Read the summary →](/serv-reasoning/research)
  * **Public roadmap.** The SERV Reasoning roadmap is now public, from the current Private Beta through Public API, fine-tuned models, and longer-horizon research. [See the roadmap →](/serv-reasoning/roadmap)

  ## Updates

  * **Model catalog and pricing.** Refreshed pricing for Claude Opus and Qwen models, plus a single page covering every available model, API ID, context window, and per-million-token rate. [Browse models →](/serv-reasoning/models)
  * **Quickstart.** Streamlined the [SERV Reasoning quickstart](/serv-reasoning/introduction) with first-request examples for the OpenAI SDK, Anthropic SDK, and raw HTTP.
