Gladia vs vLLM
A side-by-side editorial comparison of Gladia and vLLM — release velocity, themes, recent moves, and the top alternatives to consider.
Gladia vs vLLM: at a glance
What is Gladia?
Gladia ships a new flagship speech-to-text model and edges into the meeting-bot stack.
Gladia sells speech-to-text as an API, competing with Deepgram and AssemblyAI. Its recent work centers on model accuracy — the new Solaria-3 model and an open benchmark — alongside developer ergonomics (an official async SDK, a multilingual normalization library) and enterprise trust signals. A new Attendee integration pushes it toward live meeting transcription.
What is vLLM?
vLLM in a six-RC sprint to stabilize v0.29.0 with Mamba and hybrid prefix caching
vLLM is in intensive release candidate territory for v0.29.0, shipping six RC builds in under a week. The work is concentrated on prefix caching for Mamba and hybrid architectures, CUTLASS MoE permutation correctness, and TRT-LLM backend synchronization. None of these are user-visible capabilities — they're pre-release bug convergence.

Gladia
6.3AI-ASSISTANTS
Gladia ships a new flagship speech-to-text model and edges into the meeting-bot stack.
◆ Current state
Gladia sells speech-to-text as an API, competing with Deepgram and AssemblyAI. Its recent work centers on model accuracy — the new Solaria-3 model and an open benchmark — alongside developer ergonomics (an official async SDK, a multilingual normalization library) and enterprise trust signals. A new Attendee integration pushes it toward live meeting transcription.
◆ Where it's heading
Two threads run through the changelog: advancing the core STT model on real-world, multilingual audio, and positioning Gladia inside the meeting-assistant ecosystem it mapped publicly in May. The Attendee integration, multilingual normalization, and async SDK all lower the friction of wiring Gladia into voice and meeting products.
◆ Prediction
Expect continued Solaria model iteration and more meeting-platform integrations — or first-party bot tooling — as Gladia leans into the meeting-transcription use case it keeps signaling.
vLLM
6.3AI-ASSISTANTS
vLLM in a six-RC sprint to stabilize v0.29.0 with Mamba and hybrid prefix caching
◆ Current state
vLLM is in intensive release candidate territory for v0.29.0, shipping six RC builds in under a week. The work is concentrated on prefix caching for Mamba and hybrid architectures, CUTLASS MoE permutation correctness, and TRT-LLM backend synchronization. None of these are user-visible capabilities — they're pre-release bug convergence.
◆ Where it's heading
Repeated prefix-cache fixes for Mamba and hybrid models signal that non-transformer architecture support is being promoted to first-class status in vLLM. The CUTLASS and TRT-LLM work shows backend coverage expanding beyond vanilla GPU inference. Once v0.29.0 stable lands, the next focus is likely speculative decoding maturity — the DSpark and DFlash2 work from earlier entries were architecturally more interesting than anything in this RC cycle.
◆ Prediction
v0.29.0 stable is days away given the RC cadence. The stable release will formally include dense prefix caching as a default for Mamba models, the recurring theme across rc5 and rc6.
