What is Speakeasy?
Speakeasy moved enforcement to the proxy: a bad prompt now dies before inference, not after.
Speakeasy is an AI control plane that meters agent spend and governs MCP servers, and it crossed 1.0 at the end of July by enforcing role-based access on every plan tier instead of gating it behind a plan. The August releases widen what it can see — ChatGPT and ChatGPT Work usage now counts toward tokens under management alongside Claude Code, Codex, and Cursor — and add a second shadow-MCP posture that allows servers by default and names the ones to block. LiteLLM has become a first-class source, with prompt policies checked at the proxy.
What is Sonic?
Sonic is shipping tokenizer control and a dependency diet, two tags at a time.
Sonic is a lightweight Rust search index that now releases in pairs — a server tag (v1.7.x) and a core-crate tag (v0.1.x) covering the same underlying commits. The recent work splits between tokenizer behavior, where pattern matching became opt-in and special tokens stopped being split apart, and a dependency audit that pinned every crate, disabled default features across the board, and trimmed unused RocksDB functionality. Release cadence is tight, with several tags landing within days.
Speakeasy vs Sonic: editorial side-by-side
Speakeasy
10.0DEVOPS
Speakeasy moved enforcement to the proxy: a bad prompt now dies before inference, not after.
◆ Current state
Speakeasy is an AI control plane that meters agent spend and governs MCP servers, and it crossed 1.0 at the end of July by enforcing role-based access on every plan tier instead of gating it behind a plan. The August releases widen what it can see — ChatGPT and ChatGPT Work usage now counts toward tokens under management alongside Claude Code, Codex, and Cursor — and add a second shadow-MCP posture that allows servers by default and names the ones to block. LiteLLM has become a first-class source, with prompt policies checked at the proxy.
◆ Where it's heading
The product is moving from observing AI usage to intercepting it. Early releases catalogued spend and inventoried shadow MCP servers; the newest ones stop a policy-violating prompt before it reaches a model, and turn a bypass approval into a project-wide unblock rather than a private exception. Coverage breadth and enforcement point are being pushed together, which is what a control plane needs in order to be authoritative rather than advisory.
◆ Prediction
Expect more first-class sources onboarded through the same proxy-ingestion pattern, and the project assistant to keep gaining the ability to act on findings rather than list them. The entries say nothing about enforcement latency or what happens when the proxy check fails, which is the open question for anything sitting in the request path.
Sonic
5.0DEVOPS
Sonic is shipping tokenizer control and a dependency diet, two tags at a time.
◆ Current state
Sonic is a lightweight Rust search index that now releases in pairs — a server tag (v1.7.x) and a core-crate tag (v0.1.x) covering the same underlying commits. The recent work splits between tokenizer behavior, where pattern matching became opt-in and special tokens stopped being split apart, and a dependency audit that pinned every crate, disabled default features across the board, and trimmed unused RocksDB functionality. Release cadence is tight, with several tags landing within days.
◆ Where it's heading
Two things are happening at once. The tokenizer changes are aimed at correctness for users indexing identifiers and structured strings — the recurring theme of treating more strings as IDs and performing implicit AND on ID queries suggests the index was mangling exactly the inputs developers reach for it with. The dependency work reads as supply-chain and binary-size discipline: pinning everything and disabling default features is what a project does when it wants a small, auditable, reproducible build. The core/server split into separate crates is what makes the paired tags necessary.
◆ Prediction
Expect the tokenizer work to continue toward configurable behavior rather than better defaults, given pattern matching was made opt-in and non-breaking in the same release. The paired v1.7.x/v0.1.x tagging will keep producing two changelog entries per actual release.
