What's New in Spike AI

2.0.7

October 29, 2026

Ready for iPhone Duo: on the outer display and in multitasking, the chat buttons sit in the system's side bar. On the large display the side menu stands beside the chat and opens and closes in one smooth motion. Open Spike twice, side by side. Your own server and on-device models: the message bar now shows only what works for the chosen model, with a phone mark for models running on your iPhone. Suggestions for your next message appear in the empty message bar again. Max Mode has been retired. More reliable notifications and many small fixes.

Good but…

It takes a really long time to answer questions

Response from developer

Thank you for your feedback! If you’re using an On‑Device model, try the smaller Spike 2B model for faster responses. Also enable only the tools you need in the Quick Menu—larger models and more active tools require more processing and can make answers take longer. We’re continuing to improve performance and make these choices clearer in the app.

No Response

I can’t get a response from this app. It just sits there.

Response from developer

Sorry—Spike should not have just sat there. In version 1.6.5, messages could be sent without a configured model source, and the connection error was sometimes hidden instead of explaining what was missing. Spike requires either a configured server or a downloaded On-Device model. We appreciate you bringing this to our attention.

Nothing Loads; Slow AI replies

It would’ve been ok, if the response and replies don’t take 7+ minutes for the AI to generate an answer. Thats kind of ridiculous.

Response from developer

You’re right—waiting seven minutes for a reply is far too long. This version can run AI entirely on the iPhone, and larger On-Device models may be very slow depending on the device. Selecting a smaller compatible model should improve performance, but the app should have explained that tradeoff much more clearly. Thank you for the feedback.

Tools, MLX, and Voice Chat!

This is one of very few free apps offering so many great features for fully local LLMs. Nice clean interface, supports MLX, tons of tools. Soprano TTS and Qwen ASR!

Not Bad

You guys are off to a good start and you probably have the best client app on iOS. That being said, I have one major gripe people do a lot of research and document creation with AI that should’ve been one of the core aspects of the app.. But that turned out to be the Achilles heel of the app.

You checked every other box except for that one.. And it would be nice if you also added MCP Tools. Can we make this app more like a mobile agent?
