Tinfoil Release Notes

New SDK: Rust

Released the Tinfoil Rust SDK at v0.0.3 with attestation-verified TLS, an async-openai-compatible chat surface, and first-class shortcuts for chat (chat_relaxed), embeddings (embed_batch), and audio transcription (transcribe). Streams Tinfoil-specific vendor events (web search progress, structured-outputs constraints, PII checks) through a permissive JSON builder. Crate: tinfoilsh/tinfoil-rs

Model Sunset: Whisper Large V3 Turbo

Whisper Large V3 Turbo (whisper-large-v3-turbo) has been removed from the catalog. Use Voxtral Small 24B (voxtral-small-24b) for speech-to-text transcription.

Document Processing API: New Pipeline

PDF parsing moved from docling to sandboxed MuPDF; scanned pages route to the gemma4-31b VLM. Adds a mode query parameter on /v1/convert/file (text, vision, images, raw, vlm), multi-file uploads, and proper 502 failures on OCR errors. See the Document Processing Guide.

New Model: DeepSeek V4 Pro

Added support for DeepSeek V4 Pro, a 1.6T-parameter Mixture-of-Experts model with 49B active parameters per token, strong long-context reasoning, coding, math, and agentic task performance. Model ID: deepseek-v4-pro

New Model: Kimi K2.6

Added support for Kimi K2.6, Moonshot’s latest multimodal agentic model with stronger long-horizon coding, design-to-code, image and video understanding, and large-scale tool-using workflows. Model ID: kimi-k2-6

New Model: GLM-5.1

Added support for GLM-5.1, a frontier-class model built for agentic engineering with state-of-the-art performance on coding benchmarks and sustained reasoning over long tool-use sessions. Model ID: glm-5-1

New Model: Gemma 4 31B

Added support for Gemma 4 31B, a multimodal model from Google DeepMind with image understanding, built-in thinking mode, and native function calling. Model ID: gemma4-31b

Model Sunset: DeepSeek R1

DeepSeek R1 (deepseek-r1-0528) has been removed from the catalog.

Model Sunset: Kimi K2.5

Kimi K2.5 (kimi-k2-5) has been removed from the catalog.

New Model: Kimi K2 Thinking

Added support for Kimi K2 Thinking, an advanced thinking agent with deep multi-step reasoning and stable long-horizon tool orchestration capabilities. Model ID:

kimi-k2-thinking

Model Sunset: DeepSeek V3.1 Terminus

DeepSeek V3.1 Terminus (

deepseek-v31-terminus

) has been removed from the catalog.

Tinfoil Code Sunset

The Tinfoil Code experiment has been discontinued. Maintaining feature parity with the upstream Qwen-Code project proved unsustainable, and we shut down the experiment.

Encrypted HTTP Body Protocol (EHBP)

Breaking Change: The API now supports Encrypted HTTP Body Protocol (EHBP) for end-to-end encryption of request and response payloads using attested encryption keys while keeping HTTP headers in the clear for routing purposes. EHBP cryptographically guarantees that user data can only be decrypted inside the TEE when the key is retrieved from an attestation report.

Migration Required: Update all SDKs to version 0.10.0 or greater to maintain compatibility.

Python: pip install --upgrade tinfoil>=0.10.0

JavaScript: npm install tinfoil@latest

Swift: Update package dependency to 0.10.0 or greater

Go: go get github.com/tinfoilsh/tinfoil-go@latest

See the EHBP documentation for technical details.
