HomeTelegram Unleashes Major Bot API Update with Full Streaming Support
Telegram has made another major move! The official Bot API will be officially launched in version 9.5 on March 1, 2026. One of the most significant changes is the full release of the sendMessageDraft method to all bots. Previously, this feature was limited to specific scenarios (such as private chats with topics), but now all types of Telegram chatbots (including regular private chats, groups, and topics) can natively implement streaming. This allows AI responses to be displayed as they are generated, similar to ChatGPT, greatly enhancing the user experience. The open-source AI proxy framework OpenClaw has already completed its adaptation and has become the first publicly reported bot solution to fully support this new API.
Key Update Insights
The Telegram Bot API 9.5 clearly adds and expands the sendMessageDraft method. This allows bot developers to push partial message content to the user interface in real-time while generating replies, creating a "typing" bubble and dynamically updating the text. This change completely removes the previous restrictions on regular private chat bots. Now, all types of Telegram chatbots can seamlessly use streaming without requiring additional hacks or message editing workarounds.
OpenClaw's Leading Adaptation
As the most popular self-hosted AI proxy platform currently, OpenClaw has natively integrated this feature through its Telegram channel plugin. According to the official documentation and community feedback:
- In private chats (DM): It directly uses sendMessageDraft to update the draft bubble, achieving zero-latency native streaming display without sending additional preview messages.
- In groups/topics: It combines sendMessage + editMessageText to achieve real-time editing of preview messages, ensuring a consistent experience across all scenarios.
OpenClaw supports multiple streaming mode configurations (partial / block / progress, etc.). Enabling the default partial mode allows you to enjoy Telegram's latest native streaming capabilities. Developers simply need to refer to the sendMessageDraft method in the API documentation to easily integrate and optimize their own AI bots.
Significance for the AI Bot Ecosystem
This update marks Telegram's official alignment with mainstream chat AI platforms in terms of AI interaction experience. Previously, many self-built bots relied on the "send an empty message first and then constantly edit" approach to simulate streaming, which could trigger rate limits or appear unpolished. Now, with the official sendMessageDraft, all bot developers can achieve more natural and efficient real-time reply effects. Especially for platforms like OpenClaw, which act as multi-platform AI gateways, the experience of the Telegram channel has been significantly improved. This allows users to enjoy a smooth "think and speak" feeling similar to Claude or GPT on their mobile devices.
